技术领域technical field

本申请涉及计算机技术领域，特别涉及一种资源访问方法及装置。The present application relates to the field of computer technologies, and in particular, to a resource access method and device.

背景技术Background technique

低代码开发平台(Low-Code Development Platform，LCDP)是无需编码或通过少量代码就可以快速生成应用程序的开发平台。通过可视化进行应用程序开发的方法，使具有不同经验水平的开发人员可以通过图形化的用户界面，使用拖拽组件和模型驱动的逻辑来创建网页和移动应用程序。Low-Code Development Platform (LCDP) is a development platform that can quickly generate applications without coding or with a small amount of code. A visual approach to application development that enables developers of varying experience levels to create web and mobile applications using drag-and-drop components and model-driven logic through a graphical user interface.

若想要在低代码开发平台中快速预览业务应用程序(被开发的应用程序) 的效果，需要实时渲染当前应用程序，此时应用程序所属域名是低代码开发平台的域名。业务应用程序(被开发的应用程序)仅可以请求和低代码开发平台网站域名相同的接口，并不能请求其他业务域名接口。如果业务应用程序请求与其对应的业务域名接口，便出现跨域访问的情况，业务应用程序请求会被浏览器拦截。如果想要实现请求业务域名接口，需要接口提供方的业务服务器设置跨域资源共享(Cross-Origin Resource Sharing，CORS)配置，业务应用程序才能进行接口调试和效果预览。If you want to quickly preview the effect of the business application (the application being developed) in the low-code development platform, you need to render the current application in real time. At this time, the domain name to which the application belongs is the domain name of the low-code development platform. Business applications (developed applications) can only request the same interface as the low-code development platform website domain name, and cannot request other business domain name interfaces. If a business application requests its corresponding business domain name interface, cross-domain access occurs, and the business application request will be intercepted by the browser. If you want to implement the request business domain name interface, you need to set the Cross-Origin Resource Sharing (CORS) configuration on the business server of the interface provider, so that the business application can perform interface debugging and effect preview.

相关技术中，低代码开发平台中应用访问资源复杂度高、资源访问效率低。In the related art, the application access resources in the low-code development platform have high complexity and low resource access efficiency.

A client in the terminal 10 that can install applications.

在本申请实施例中，上述应用程序可以是任何能够发送网络请求的应用程序，网络请求既可以直接发送至待访问资源所在的资源服务器，也可以通过代理服务器请求资源服务器中的待访问资源。典型地，该应用程序为应用开发程序，例如低代码开发平台。由用户在低代码开发平台开发快速生成的目标应用，可在低代码开发平台中调试预览，通过低代码开发平台进行网络连接和数据传输，目标应用发送的网络请求既可以直接发送至为目标应用提供后台服务的资源服务器，也可以将低代码开发平台的后台服务器作为云端代理服务器，以帮助目标应用获取资源服务器中的待访问资源。当然，除了应用开发程序之外，其它类型的应用程序中也能够发送网络请求。例如，浏览器类应用程序、社交类应用程序、互动娱乐类应用程序、虚拟现实(Virtual Reality，VR)类应用程序、增强现实(AugmentedReality，AR)类应用程序、三维地图程序等，本申请实施例对此不作限定。另外，对于不同的应用程序来说，其发送的网络请求以及请求的网络资源也会有所不同，这都可以根据实际需求预先进行配置，本申请实施例对此不作限定。可选地，终端10中运行有上述应用程序的客户端。In this embodiment of the present application, the above application program may be any application program capable of sending network requests. The network request may be directly sent to the resource server where the resource to be accessed is located, or may request the resource to be accessed in the resource server through a proxy server. Typically, the application is an application development program, such as a low-code development platform. The user develops the quickly generated target application on the low-code development platform, can debug and preview in the low-code development platform, and perform network connection and data transmission through the low-code development platform. The network request sent by the target application can be directly sent to the target application. The resource server that provides background services can also use the background server of the low-code development platform as a cloud proxy server to help the target application obtain the resources to be accessed in the resource server. Of course, in addition to application development programs, other types of applications can also send network requests. For example, browser applications, social applications, interactive entertainment applications, virtual reality (Virtual Reality, VR) applications, augmented reality (Augmented Reality, AR) applications, 3D map programs, etc., are implemented in this application.

在介绍本申请提供的方法实施例之前，先对本申请方法实施例中可能涉及的相关术语或者名词进行简要介绍，以便于本申请领域技术人员理解。Before introducing the method embodiments provided in the present application, relevant terms or nouns that may be involved in the method embodiments of the present application are briefly introduced to facilitate the understanding of those skilled in the art of the present application.

计算机与网络设备要相互通信，双方就必须基于相同35的方法。比如，如何探测到通信目标、由哪一边先发起通信、使用哪种语言进行通信、怎样结束通信等规则都需要事先确定。不同的硬件、操作系统之间的通信，所有的这一切都需要一种规则。而我们就把这种规则称为协议(protocol)。TCP/IP是互联网相关的各类协议族的总称。For computers and network devices to communicate with each other, both sides must be based on the same 35 method. For example, rules such as how to detect the communication target, which side initiates the communication first, which language is used for communication, and how to end the communication need to be determined in advance. Communication between different hardware, operating systems, all of this requires a discipline. And we call this rule a protocol. TCP/IP is a general term for various protocol families related to the Internet.

超文本传输协议(Hypertext Transfer Protocol，HTTP)是请求-响应协议，它通常运行在TCP之上。它指定了客户端可能发送给服务器什么样的消息以及得到什么样的响应。Hypertext Transfer Protocol (HTTP) is a request-response protocol, which usually runs on top of TCP. It specifies what kind of messages the client might send to the server and what kind of response it gets.

云端：是指线上服务器。Cloud: refers to the online server.

代理服务器：是客户端与服务器之间的一个中转站，当用户访问网络上资源的时候，可通过代理服务器来访问目标资源，再返回对应的结果。其基本行为就是接收客户端发送的请求后转发给其他服务器。在HTTP通信过程中，可级联多台代理服务器。请求和响应的转发会经过数台类似锁链一样连接起来的代理服务器。转发时，需要附加首部字段以标记出经过的主机信息。Proxy server: It is a transfer station between the client and the server. When users access resources on the network, they can access the target resources through the proxy server, and then return the corresponding results. Its basic behavior is to receive the request sent by the client and forward it to other servers. During HTTP communication, multiple proxy servers can be cascaded. Requests and responses are forwarded through several proxy servers connected like a chain. When forwarding, additional header fields are required to mark the passing host information.

持有资源实体的服务器被称为源服务器。从源服务器返回的响应经过代理服务器后再传给客户端。The server holding the resource entity is called the origin server. The response returned from the origin server passes through the proxy server and then forwards it to the client.

同源策略：是指在Web浏览器中，允许某个网页脚本访问另一个网页的数据，但前提是这两个网页必须有相同的URI、主机名和端口号，一旦两个网站满足上述条件，这两个网站就被认定为具有相同来源。此策略可防止某个网页上的恶意脚本通过该页面的文档对象模型访问另一网页上的数据。在一个示例中，如图2所示，其示例性示出了应用同源策略的示意图。终端20中浏览器加载的网页的域名为www.site-a.com，若用户通过该网页请求向域名同样为 www.site-a.com的服务器21请求资源，浏览器可通过终端20，向域名为www.site-a.com的服务器21发送网络请求，以请求响应的资源。服务器21收到该请求后，判断该网络请求的发送方的域名与本地域名是否一致，若都是 www.site-a.com，且协议版本与端口均一致，便会向终端20发送携带有网络请求对应的网络资源的响应报文。若用户通过该网页向域名为www.site-b.com的服务器22请求资源，因同源策略的限制，即该网页的域名www.site-a.com与服务器22的域名www.site-b.com不一致，会导致此次网络请求失败。Same-origin policy: In a web browser, a web page script is allowed to access the data of another web page, but the premise is that the two web pages must have the same URI, host name and port number. Once the two websites meet the above conditions, The two sites are identified as having the same origin. This policy prevents malicious scripts on one web page from accessing data on another web page through that page's Document Object Model. In one example, as shown in FIG. 2 , it exemplarily shows a schematic diagram of applying the same-origin policy. The domain name of the webpage loaded by the browser in the terminal 20 is www.site-a.com. If the user requests resources from theserver 21 whose domain name is also www.site-a.com through the webpage request, the browser can use the terminal 20 to request the resource. Theserver 21 whose domain name is www.site-a.com sends a network request to request a corresponding resource. After receiving the request, theserver 21 determines whether the domain name of the sender of the network request is consistent with the local domain name. The response message of the network resource corresponding to the network request. If the user requests resources from theserver 22 whose domain name is www.site-b.com through the webpage, due to the restriction of the same-origin policy, that is, the domain name of the webpage www.site-a.com and the domain name of theserver 22 www.site-b The .com is inconsistent, which will cause the network request to fail.

跨域资源共享(Cross-Origin Resource Sharing，CORS)是用于让网页的受限资源能够被其他域名的页面访问的一种机制。通过该机制，页面能够自由地使用不同源(cross-origin)的图片、样式、脚本、iframes以及视频。一些跨域的请求常常会被同源策略(Same-origin policy)所禁止的。跨域资源共享定义了一种方式，使浏览器和服务器之间能互相确认是否足够安全以至于能使用跨域请求(cross-origin requests)。在一个示例中，如图3所示，其示例性示出了跨域资源共享的网络示意图。终端30中显示有域名为domain-a.com的浏览器页面 31，浏览器页面31中的图像32是由域名为domain-a.com的服务器33提供的，浏览器页面31向服务器33发送图像32的获取请求，服务器33收到该请求后，向终端30发送图像32。而浏览器页面31中的图像34是由域名为domain-b.com 的服务器35提供的，由于服务器35与浏览器页面31的域名不同，两者之间存在同源策略限制，因此服务器35中需要设置跨域资源共享的配置信息，只有在服务器35中设置允许浏览器页面31进行跨域资源共享的配置信息后，服务器 35与浏览器页面31才能突破两者之间的同源策略限制，由终端30向服务器35 发送图像34的获取请求，服务器35接收到图像34的获取请求后向终端30发送图像34。这样，浏览器页面31中才可以正常显示图像34。Cross-Origin Resource Sharing (CORS) is a mechanism for enabling restricted resources of web pages to be accessed by pages of other domains. Through this mechanism, pages are free to use cross-origin images, styles, scripts, iframes, and videos. Some cross-origin requests are often prohibited by the same-origin policy. Cross-origin resource sharing defines a way for browsers and servers to mutually confirm that they are secure enough to use cross-origin requests. In one example, as shown in FIG. 3 , it exemplarily shows a network diagram of cross-domain resource sharing. The terminal 30 displays abrowser page 31 whose domain name is domain-a.com, theimage 32 in thebrowser page 31 is provided by aserver 33 whose domain name is domain-a.com, and thebrowser page 31 sends the image to theserver 33 32 . After receiving the request, theserver 33 sends theimage 32 to the terminal 30 . Theimage 34 in thebrowser page 31 is provided by theserver 35 whose domain name is domain-b.com. Since the domain names of theserver 35 and thebrowser page 31 are different, there is a same-origin policy restriction between the two, so theserver 35 has a different domain name. The configuration information of cross-domain resource sharing needs to be set. Only after the configuration information that allows thebrowser page 31 to perform cross-domain resource sharing is set in theserver 35, theserver 35 and thebrowser page 31 can break through the same-origin policy restriction between the two. The terminal 30 sends an acquisition request for theimage 34 to theserver 35 , and theserver 35 sends theimage 34 to the terminal 30 after receiving the acquisition request for theimage 34 . In this way, theimage 34 can be displayed normally in thebrowser page 31 .

URI(Uniform Resource Identifier，统一资源标识符)，规定统一的格式可方便处理多种不同类型的资源，而不用根据上下文环境来识别资源指定的访问方式。另外，加入新增的协议方案(如http：或ftp:)也更容易。Resource资源的定义是“可标识的任何东西”。不仅是文档文件，图像或服务(例如当天的天气预报)等能够区别于其他类型的，全都可作为资源。另外，资源不仅可以是单一的，也可以是多数的集合体。Identifier表示可标识的对象。也称为标识符。综上所述，URI就是由某个协议方案表示的资源的定位标识符。协议方案是指访问资源所使用的协议类型名称。URI (Uniform Resource Identifier, Uniform Resource Identifier), specifies a unified format to facilitate the processing of multiple different types of resources, without identifying the access method specified by the resource according to the context. In addition, it is easier to add new protocol schemes such as http: or ftp:. The definition of Resource is "anything that can be identified". Not only document files, but also images or services (such as the weather forecast for the day) can be distinguished from other types, all of which can be used as resources. In addition, the resource may be not only a single, but also a plurality of aggregates. Identifier represents an identifiable object. Also called an identifier. In summary, a URI is a location identifier for a resource represented by a protocol scheme. The protocol scheme refers to the name of the protocol type used to access the resource.

URL(UniformResource Locator，统一资源定位符)，URI用字符串标识某一互联网资源，而URL表示资源的地点(互联网上所处的位置)。可见URL是 URI的子集。URL (UniformResource Locator, Uniform Resource Locator), URI identifies a certain Internet resource with a string, and URL indicates the location of the resource (the location on the Internet). Visible URLs are a subset of URIs.

XMLHTTP是一组API函数集，可被JavaScript、JScript、VBScript以及其它web浏览器内嵌的脚本语言调用，通过HTTP在浏览器和web服务器之间收发XML或其它数据。XMLHTTP最大的好处在于可以动态地更新网页，它无需重新从服务器读取整个网页，也不需要安装额外的插件。该技术被许多网站使用，以实现快速响应的动态网页应用。例如：Google的Gmail服务、Google Suggest 动态查找界面以及Google Map地理信息服务。XMLHTTP is a set of API functions that can be invoked by JavaScript, JScript, VBScript and other scripting languages embedded in web browsers to send and receive XML or other data between browsers and web servers through HTTP. The biggest advantage of XMLHTTP is that it can dynamically update web pages without re-reading the entire web page from the server or installing additional plug-ins. This technology is used by many websites to achieve fast and responsive dynamic web applications. For example: Google's Gmail service, Google Suggest dynamic search interface and Google Map geographic information service.

Ajax(Asynchronous JavaScript and XML，异步JavaScript与XML技术)是一种有效利用JavaScript和DOM(Document Object Model，文档对象模型)的操作，以达到局部Web页面替换加载的异步通信手段。和以前的同步通信相比，由于它只更新一部分页面，响应中传输的数据量会因此而减少，这一优点显而易见。Ajax的核心技术是名为XMLHttpRequest的API，通过JavaScript脚本语言的调用就能和服务器进行HTTP通信。借由这种手段，就能从已加载完毕的 Web页面上发起请求，只更新局部页面。Ajax (Asynchronous JavaScript and XML, asynchronous JavaScript and XML technology) is an asynchronous communication method that effectively utilizes JavaScript and DOM (Document Object Model, Document Object Model) to achieve partial Web page replacement loading. Compared to the previous synchronous communication, since it only updates a part of the page, the amount of data transferred in the response is reduced, which is an obvious advantage. The core technology of Ajax is an API called XMLHttpRequest, which can communicate with the server through HTTP calls by the JavaScript scripting language. In this way, a request can be initiated from a loaded Web page and only a partial page is updated.

请参考图4，其示出了本申请一个实施例提供的资源访问方法的流程图。该方法可应用于计算机设备中，所述计算机设备是指具备数据计算和处理能力的电子设备，如各步骤的执行主体可以是图1所示的应用程序运行环境中的终端 10。该方法可以包括以下几个步骤(410～450)。Please refer to FIG. 4 , which shows a flowchart of a resource access method provided by an embodiment of the present application. The method can be applied to computer equipment, which refers to electronic equipment with data computing and processing capabilities, for example, the execution subject of each step may be the terminal 10 in the application running environment shown in FIG. 1 . The method may include the following steps (410-450).

步骤410，获取目标应用发送的资源请求报文。Step 410: Obtain the resource request message sent by the target application.

可选地，目标应用为程序开发应用中调试预览的应用。资源请求报文包括待访问资源的位置信息。Optionally, the target application is a debug preview application in the program development application. The resource request message includes location information of the resource to be accessed.

资源请求报文是指为了请求访问服务器上的网络资源发送的请求报文。The resource request message refers to a request message sent to request access to network resources on the server.

可选地，获取目标应用在调试预览过程中发送的资源请求报文。上述待访问资源是指目标应用在调试预览过程中请求的网络资源。Optionally, obtain a resource request message sent by the target application during the debugging preview process. The above resource to be accessed refers to the network resource requested by the target application in the process of debugging and previewing.

在一种可能的实施方式中，终端中加载显示程序开发应用的应用页面，在程序开发应用的应用页面中显示目标应用页面的调试预览页面。用户可以在目标应用的调试预览页面中执行调试操作。在用户操作涉及资源访问的情况下，会触发生成相应的资源访问指令，响应于资源访问指令，目标应用生成资源请求报文。目标应用为获取待访问资源，需要向服务器发送资源请求报文，上述服务器可以是为目标应用提供网络资源服务的后台服务器，也可以是云端代理服务器。可选地，程序开发应用的后台服务器可以作为目标应用的代理服务器。In a possible implementation manner, an application page displaying the program development application is loaded in the terminal, and a debugging preview page of the target application page is displayed in the application page of the program development application. Users can perform debug operations in the debug preview page of the target app. When the user operation involves resource access, it will trigger the generation of a corresponding resource access instruction, and in response to the resource access instruction, the target application generates a resource request message. In order to obtain the resource to be accessed, the target application needs to send a resource request message to the server. The server may be a background server that provides network resource services for the target application, or a cloud proxy server. Optionally, the background server of the program development application can serve as the proxy server of the target application.

在一种可能的实施方式中，目标应用可通过调用程序开发应用的请求发送接口，发送资源请求报文。可选地，上述请求发送接口是应用开发程序为目标应用发送网络请求设置的应用程序接口。程序开发应用基于请求发送规则，拦截目标应用发送的资源请求报文。由于目标应用是运行在程序开发应用下的，其所用到的所有API都是由程序开发应用提供的，因此作为程序开发应用侧可以拦截目标的所有HTTP请求。比如程序开发应用提供的HTTP请求API是 app.request，即可在app.requeset函数方法里面编写代码逻辑对所有的请求进行拦截。In a possible implementation manner, the target application may send the resource request message by invoking the request sending interface of the program development application. Optionally, the above-mentioned request sending interface is an application program interface set by the application development program for sending a network request to the target application. The program development application intercepts the resource request message sent by the target application based on the request sending rule. Since the target application runs under the program development application, all APIs used by the target application are provided by the program development application, so the program development application side can intercept all HTTP requests of the target. For example, the HTTP request API provided by the program development application is app.request, and you can write code logic in the app.requeset function method to intercept all requests.

步骤420，若资源请求报文的报文发送模式为跨域代理模式，则生成代理标识参数。Step 420: If the message sending mode of the resource request message is the cross-domain proxy mode, generate a proxy identification parameter.

报文发送模式是指请求报文向服务器发送的方式。可选地，报文发送模式包括同域发送模式、跨域代理模式。上述同域发送模式是指报文发送方与报文接收方符合同源策略的发送方式，报文发送方与报文接收方的域名，协议，端口均相同。上述跨域代理模式是指报文发送方与报文接收方的域名、协议、端口任一项不同的情况下，报文发送方与报文接收方通过代理服务传输报文的方式。The message sending mode refers to the way in which request messages are sent to the server. Optionally, the message sending mode includes a same-domain sending mode and a cross-domain proxy mode. The above-mentioned same-domain sending mode refers to the sending method in which the message sender and the message receiver conform to the same-origin policy. The domain name, protocol, and port of the message sender and the message receiver are the same. The above-mentioned cross-domain proxy mode refers to the way in which the message sender and the message receiver transmit messages through a proxy service when any of the domain names, protocols, and ports of the message sender and the message receiver are different.

其中，代理标识参数用于在代理服务器设置缓存策略的情况下，标识跨域代理请求的唯一性。The proxy identifier parameter is used to identify the uniqueness of the cross-domain proxy request when the proxy server sets the cache policy.

缓存是指代理服务器或客户端本地磁盘内保存的资源副本。利用缓存可减少对源服务器的访问，因此也就节省了通信流量和通信时间。上述缓存策略是指预先将资源的副本(缓存)保存在代理服务器或者客户端上。当代理服务器或者客户端再次接收到对相同资源的请求时，就可以不从源服务器那里获取资源，而是将之前缓存的资源作为响应返回，减少网络带宽的流量。A cache is a copy of a resource held on a proxy server or client's local disk. Using caching reduces access to origin servers, thus saving communication traffic and communication time. The above caching strategy refers to storing a copy (cache) of the resource on the proxy server or the client in advance. When the proxy server or client receives a request for the same resource again, it can not obtain the resource from the origin server, but return the previously cached resource as a response, reducing the traffic of network bandwidth.

可选地，缓存具有有效期限。即便代理服务器或者客户端内有缓存，也不能保证每次都会返回对同资源的请求。因为这关系到被缓存资源的有效性问题，当遇上源服务器上的资源更新时，如果还是使用不变的缓存，那就会演变成返回更新前的“旧”资源了。即使存在缓存，也会因为客户端的要求、缓存的有效期等因素，向源服务器确认资源的有效性。若判断缓存失效，将会再次从源服务器上获取更新后的网络资源。Optionally, the cache has an expiration date. Even if there is a cache in the proxy server or client, there is no guarantee that a request for the same resource will be returned every time. Because this is related to the validity of the cached resource, when the resource on the origin server is updated, if the unchanged cache is still used, it will evolve into returning the "old" resource before the update. Even if there is a cache, the validity of the resource will be confirmed to the origin server due to the client's request and the validity period of the cache. If it is determined that the cache is invalid, the updated network resources will be obtained from the origin server again.

可选地，请求报文中包含max-age指令，max-age指令指定文档被访问后的存活时间，这个时间是个相对值，相对的是文档第一次被请求时服务器记录的请求时间。在客户端发送的请求中包含max-age指令时，如果判定缓存资源的缓存时间数值比指定时间的数值更小，那么客户端就接收缓存的资源。当服务器返回的响应中包含max-age指令时，代理服务器将不对资源的有效性再作确认，max-age数值代表资源保存为缓存的最长时间。Optionally, the request message contains a max-age instruction, and the max-age instruction specifies the survival time after the document is accessed. This time is a relative value, which is relative to the request time recorded by the server when the document is requested for the first time. When the request sent by the client contains the max-age command, if it is determined that the cache time value of the cached resource is smaller than the specified time value, then the client receives the cached resource. When the response returned by the server contains the max-age directive, the proxy server will not confirm the validity of the resource, and the max-age value represents the maximum time that the resource is stored in the cache.

由于代理服务器的代理服务接口地址是固定的，客户端每次发送的跨域代理请求(下文进行介绍)的请求路径都会指向这一固定的代理服务接口地址，代理服务器会对跨域代理请求的请求路径进行判定，容易将此次发送的跨域代理请求认定为，与接收到的跨域代理请求是相同的请求，其请求资源相同，进而误将代理服务器缓存内容返回给客户端，或者错误地指示客户端从客户端本地缓存中获取待访问资源，导致代理服务器未能正确地根据跨域代理请求向资源服务器获取待访问资源并转发至客户端。示意性地，如果有部分跨域代理请求的对应的响应报文的响应头设置了max-age＝31536000，immutable(表征强缓存)的话，后续的跨域代理请求将永远不会再到达代理服务器。Since the proxy service interface address of the proxy server is fixed, the request path of each cross-domain proxy request (described below) sent by the client will point to this fixed proxy service interface address. To determine the request path, it is easy to determine that the cross-domain proxy request sent this time is the same request as the received cross-domain proxy request, and its requested resources are the same, and then the cached content of the proxy server is returned to the client by mistake, or an error Instructs the client to obtain the resource to be accessed from the client's local cache, so that the proxy server fails to correctly obtain the resource to be accessed from the resource server according to the cross-domain proxy request and forward it to the client. Illustratively, if the response header of the corresponding response packet of some cross-domain proxy requests is set with max-age=31536000, which is immutable (representing strong caching), subsequent cross-domain proxy requests will never reach the proxy server. .

为了避免上述情况发生，可生成代理标识参数，添加至跨域代理请求中，标识跨域代理请求的唯一性，使得代理服务器在设置缓存策略的情况下，仍能够正确地根据跨域代理请求向资源服务器获取待访问资源并转发至客户端。In order to avoid the above situation, the proxy identification parameter can be generated and added to the cross-domain proxy request to identify the uniqueness of the cross-domain proxy request, so that the proxy server can still correctly send the request according to the cross-domain proxy request when the cache policy is set. The resource server obtains the resource to be accessed and forwards it to the client.

可选地，代理标识参数为时间戳参数。可选地，标识参数为随机产生的字符串。可选地，代理标识参数为随机产生的数字序列。在一种可能的实施方式中，根据时刻信息确定上述时间戳参数。例如，根据当前时刻确定时间戳参数。Optionally, the proxy identification parameter is a timestamp parameter. Optionally, the identification parameter is a randomly generated string. Optionally, the proxy identification parameter is a randomly generated number sequence. In a possible implementation manner, the above time stamp parameter is determined according to the time information. For example, the timestamp parameter is determined according to the current moment.

下面进行举例说明，浏览器向www.a.com发送HTTP请求，浏览器基于该 HTTP请求生成跨域代理请求并初次向代理服务器发送该跨域代理请求，跨域代理请求的请求路径为www.lowcode.com/proxy，即代理服务器中代理服务的接口地址。代理服务器针对此跨域代理请求生成响应报文，并设置响应报文的响应头，告诉浏览器，这个请求地址www.lowcode.com/proxy可以缓存。当浏览器向 www.b.com发送HTTP请求的时候，浏览器若还是生成请求路径为 www.lowcode.com/proxy的跨域代理请求，因代理服务器的缓存策略，浏览器便无法获得www.b.com中的网络资源。此时可在请求路径中添加代理标识参数，如时间戳参数t＝4564564654564，那么跨域代理请求的请求路径为 www.lowcode.com/proxy？t＝456456465456，由于加了时间戳参数，使得本次跨域代理请求与上次跨域代理请求的请求路径不相同，可强制刷新缓存，避免上述情况发生，代理服务器便会帮助浏览器获取www.b.com中的网络资源，在节省网络传输效率的同时，仍能保证跨域资源的正确访问。The following is an example, the browser sends an HTTP request to www.a.com, the browser generates a cross-domain proxy request based on the HTTP request and sends the cross-domain proxy request to the proxy server for the first time, and the request path of the cross-domain proxy request is www. lowcode.com/proxy, the interface address of the proxy service in the proxy server. The proxy server generates a response message for the cross-domain proxy request, and sets the response header of the response message to tell the browser that the request address www.lowcode.com/proxy can be cached. When the browser sends an HTTP request to www.b.com, if the browser still generates a cross-domain proxy request with the request path www.lowcode.com/proxy, the browser cannot obtain www. Web resources in b.com. At this time, the proxy identification parameter can be added to the request path, such as the timestamp parameter t=4564564654564, then the request path of the cross-domain proxy request is www.lowcode.com/proxy? t=456456465456, because the timestamp parameter is added, the request path of this cross-domain proxy request is different from the last cross-domain proxy request, and the cache can be forced to refresh to avoid the above situation, and the proxy server will help the browser to obtain www The network resources in .b.com can still ensure correct access to cross-domain resources while saving network transmission efficiency.

在示例性实施例中，位置信息包括待访问资源的第二域名信息，资源请求报文的报文发送模式可通过如下方法确定。In an exemplary embodiment, the location information includes second domain name information of the resource to be accessed, and the message sending mode of the resource request message can be determined by the following method.

获取目标应用的第一域名信息；根据第二域名信息以及第一域名信息，确定报文发送模式；若第一域名信息与第二域名信息不一致，则确定报文发送模式为跨域代理模式；若第一域名信息与第二域名信息一致，则确定报文发送模式为同域发送模式。上述第一域名信息是指目标应用的域名信息，上述第二域名信息是指待访问资源的域名信息。用户请求的业务服务器如果在本地 (localhost/127.0.0.1，局域网)或者业务域名是通过改本地hosts来实现的时候，服务器代理转发是无法请求用户本地的服务器的，此时代理请求转发功能不仅帮不上忙，还阻塞了开发流程，耽误了开发时间，通过客户端来智能判别是否开启跨域代理模式，提升开发效率，保证开发顺利进行。Obtain the first domain name information of the target application; determine the message sending mode according to the second domain name information and the first domain name information; if the first domain name information is inconsistent with the second domain name information, determine that the message sending mode is the cross-domain proxy mode; If the first domain name information is consistent with the second domain name information, it is determined that the message sending mode is the same domain sending mode. The above-mentioned first domain name information refers to the domain name information of the target application, and the above-mentioned second domain name information refers to the domain name information of the resource to be accessed. If the business server requested by the user is local (localhost/127.0.0.1, local area network) or the business domain name is implemented by changing the local hosts, the server proxy forwarding cannot request the user's local server. At this time, the proxy request forwarding function not only helps If you are not busy, it also blocks the development process and delays the development time. The client can intelligently determine whether to enable the cross-domain proxy mode, improve development efficiency, and ensure smooth development.

在一种可能的实施方式中，将待访问资源的位置信息与本地网络地址进行比较，进而确定报文发送模式。通常，本地网络地址为localhost/127.0.0.1/ 10.*.*.1/192.168.*.*，其中*代表任一数字。或者检查本地网络地址文件，检查本地网络地址文件中的网络地址是否与待访问资源的位置信息匹配。若待访问资源的位置信息与本地网络地址匹配，则确定报文发送模式为同域发送模式。若待访问资源的位置信息与本地网络地址不匹配，则确定报文发送模式为跨域代理模式。In a possible implementation manner, the location information of the resource to be accessed is compared with the local network address, so as to determine the message sending mode. Typically, the local network address is localhost/127.0.0.1/10.*.*.1/192.168.*.*, where * represents any number. Or check the local network address file to check whether the network address in the local network address file matches the location information of the resource to be accessed. If the location information of the resource to be accessed matches the local network address, it is determined that the message sending mode is the same-domain sending mode. If the location information of the resource to be accessed does not match the local network address, it is determined that the packet sending mode is the cross-domain proxy mode.

在一种可能的实施方式中，将待访问资源的位置信息与低码开发平台域名 (即代理服务器域名)进行比较，进而确定报文发送模式。若待访问资源的位置信息与低码开发平台域名匹配，则确定报文发送模式为同域发送模式。若待访问资源的位置信息与低码开发平台域名不匹配，则确定报文发送模式为跨域代理模式。在一种可能的实施方式中，响应于跨域代理模式的设置指令，设置报文发送模式为跨域代理模式。例如，响应于针对应用页面中的跨域代理按钮的点击操作，设置报文发送模式为跨域代理模式。在一个示例中，如图5所示，其示例性示出了一种设置跨域代理模式的页面示意图。用户可通过点击应用开发程序页面50中的跨域请求代理按钮51，使跨域请求代理按钮51保持在开启状态，调试预览区域52中目标应用即可通过跨域代理模式访问相应的网络资源。In a possible implementation manner, the location information of the resource to be accessed is compared with the domain name of the low-code development platform (ie, the domain name of the proxy server), and then the message sending mode is determined. If the location information of the resource to be accessed matches the domain name of the low-code development platform, it is determined that the message sending mode is the same-domain sending mode. If the location information of the resource to be accessed does not match the domain name of the low-code development platform, it is determined that the message sending mode is the cross-domain proxy mode. In a possible implementation manner, in response to the setting instruction of the cross-domain proxy mode, the packet sending mode is set to the cross-domain proxy mode. For example, in response to a click operation on the cross-domain proxy button in the application page, the message sending mode is set to the cross-domain proxy mode. In an example, as shown in FIG. 5 , it exemplarily shows a schematic diagram of a page for setting a cross-domain proxy mode. The user can click the cross-domainrequest proxy button 51 in the applicationdevelopment program page 50 to keep the cross-domainrequest proxy button 51 in the open state, and the target application in thedebugging preview area 52 can access corresponding network resources through the cross-domain proxy mode.

在另一种可能的实施方式中，若第一域名信息与第二域名信息不一致，则确定待访问资源的来源信息；若来源信息中包括第一域名信息，则确定报文发送模式为同域发送模式；若来源信息中不包括第一域名信息，则确定报文发送模式为跨域代理模式。这里以低代码开发平台为例，对上述步骤进行说明，用户在低代码开发平台中可以上传目标应用使用的数据源，由低代码开发平台将上述数据源部署至业务服务器中，低代码开发平台中也可以存储上述数据源，目标应用在发布前会先调试预览，此时数据源既可以在代理服务器中，也可以在资源服务器中，若上述来源信息表征待访问资源是来自于上述数据源(即来源信息中包括第一域名信息)，虽然第二域名信息与第一域名信息不一致，但是代理服务器中具有同样的待访问资源，此时客户端可以直接向代理服务器获取待访问资源(即确定报文发送模式为同域发送模式)，无需再由代理服务器向资源服务器获取待访问资源。In another possible implementation, if the first domain name information is inconsistent with the second domain name information, the source information of the resource to be accessed is determined; if the source information includes the first domain name information, it is determined that the message sending mode is the same domain Sending mode; if the source information does not include the first domain name information, it is determined that the message sending mode is the cross-domain proxy mode. Taking the low-code development platform as an example, the above steps are described. The user can upload the data source used by the target application in the low-code development platform, and the low-code development platform deploys the above data source to the business server. The low-code development platform The above data source can also be stored in the target application, and the target application will be debugged and previewed before release. At this time, the data source can be in the proxy server or the resource server. If the above source information indicates that the resource to be accessed is from the above data source (that is, the source information includes the first domain name information), although the second domain name information is inconsistent with the first domain name information, but the proxy server has the same resources to be accessed, at this time the client can directly obtain the resources to be accessed from the proxy server (ie It is determined that the message sending mode is the same-domain sending mode), and it is no longer necessary for the proxy server to obtain the resource to be accessed from the resource server.

步骤430，根据代理标识参数和位置信息生成跨域代理请求。Step 430: Generate a cross-domain proxy request according to the proxy identification parameter and the location information.

上述跨域代理请求以请求报文的方式发送，请求报文是由请求方法、请求 URI、协议版本、可选的请求首部字段和内容实体构成的。其中，请求访问服务器的类型，称为请求方法(method)。指明请求访问的资源对象的字符串，例如 /index.htm，也叫做请求URI(request-URI)。协议版本是指HTTP的版本号，用来提示客户端使用的HTTP协议功能。综合来看，资源请求报文请求内容的意思大致可以理解为：请求访问某台HTTP服务器上的/index.htm页面资源。The above cross-domain proxy request is sent in the form of a request message. The request message is composed of the request method, request URI, protocol version, optional request header fields and content entities. Among them, the type of the request to access the server is called the request method (method). A string indicating the resource object requested to access, such as /index.htm, also known as the request-URI (request-URI). The protocol version refers to the version number of HTTP, which is used to indicate the HTTP protocol function used by the client. In general, the meaning of the content of the resource request message can be roughly understood as: requesting access to the /index.htm page resource on an HTTP server.

将资源请求报文中的请求URI(也可是目标地址URL)存储到请求报文的请求头中，并替换资源请求报文中的请求URI(也可是目标地址URL)为代理服务器专门用于代理的接口地址，生成跨域代理请求。此时由于跨域代理请求的请求域名和代理服务器所属的域名是一致的，此时跨域代理请求不会受同源策略影响，资源服务器也不需要额外设置跨域资源共享(CORS)配置，就能通过代理服务器正常访问资源。Store the request URI (or the target address URL) in the resource request message into the request header of the request message, and replace the request URI (or the target address URL) in the resource request message with the proxy server for proxy use. interface address to generate cross-domain proxy requests. At this time, since the request domain name of the cross-domain proxy request is the same as the domain name to which the proxy server belongs, the cross-domain proxy request will not be affected by the same-origin policy, and the resource server does not need to set additional cross-domain resource sharing (CORS) configuration. You can access resources normally through the proxy server.

在一种可能的实施方式中，根据代理服务器的地址以及代理标识参数，生成目标地址信息；基于目标地址信息和位置信息，生成跨域代理请求。In a possible implementation manner, the target address information is generated according to the address of the proxy server and the proxy identification parameter; the cross-domain proxy request is generated based on the target address information and the location information.

上述目标地址信息是指跨域代理请求的请求路径信息。可选地，目标地址信息由代理服务器的地址以及代理标识参数构成。上述位置信息为待访问资源的位置信息，将待访问资源的位置信息存储于跨域代理请求的请求头中。The above target address information refers to the request path information of the cross-domain proxy request. Optionally, the target address information consists of the address of the proxy server and the proxy identification parameter. The above location information is the location information of the resource to be accessed, and the location information of the resource to be accessed is stored in the request header of the cross-domain proxy request.

在示例性实施例中，对代理服务器的地址以及代理标识参数进行拼接处理，生成跨域代理请求的目标地址信息。In an exemplary embodiment, the address of the proxy server and the proxy identification parameter are concatenated to generate the target address information of the cross-domain proxy request.

在示例性实施例中，将资源请求报文的接收地址信息，由待访问资源的位置信息，替换为目标地址信息；再将待访问资源的位置信息存储到资源请求报文的请求头中，生成跨域代理请求。In an exemplary embodiment, the receiving address information of the resource request message is replaced by the location information of the resource to be accessed with the target address information; and then the location information of the resource to be accessed is stored in the request header of the resource request message, Generate cross-domain proxy requests.

在一种可能的实施方式中，这里以应用开发程序为低代码开发平台为例进行说明，低代码开发平台可以被集成到其他的应用平台中，作为其他的应用平台中的一个功能。假如其他的应用平台的域名为www.x.com，那么低代码开发平台的域名为www.x.com/lowcode，低代码开发平台的代理接口地址为 www.x.com/lowcode/proxy，此时跨域代理请求的目标地址信息是由低代码开发平台的代理接口地址与上述时间戳参数进行拼接处理得到的。In a possible implementation, the application development program is taken as an example of a low-code development platform for illustration, and the low-code development platform can be integrated into other application platforms as a function of other application platforms. If the domain name of other application platforms is www.x.com, then the domain name of the low-code development platform is www.x.com/lowcode, and the proxy interface address of the low-code development platform is www.x.com/lowcode/proxy. The target address information requested by the time cross-domain proxy is obtained by splicing the proxy interface address of the low-code development platform and the above timestamp parameter.

在示例性实施例中，上述资源请求报文还包括目标应用的应用标识参数。上述应用标识参数是表征上述目标应用的唯一的编码，以区别其他应用。上述代理服务器的地址可通过如下方式确定。In an exemplary embodiment, the above resource request message further includes an application identification parameter of the target application. The above-mentioned application identification parameter is a unique code that characterizes the above-mentioned target application, so as to distinguish other applications. The address of the above proxy server can be determined as follows.

获取代理授权信息，上述代理授权信息表征各应用与各应用授权的代理服务器之间的映射关系；根据应用标识参数与代理授权信息，确定目标应用授权的目标代理服务器；相应地，对目标代理服务器的地址以及代理标识参数进行拼接处理，生成跨域代理请求的目标地址信息。上述目标代理服务器可以代理服务器集群中被目标应用授权的代理服务器，上述代理服务器集群可以是低代码开发平台的各后台服务器构成的集群，由低代码开发平台的各后台服务器提供代理服务。上述目标代理服务器的地址可以是目标代理服务器的代理接口的接口地址，上述代理接口可以是目标代理服务器的各个代理接口中被目标应用授权的代理接口。上述目标代理服务器的地址还可以是部署于目标代理服务器中运行代理服务的容器的接口地址，上述容器可以是目标代理服务器的各个容器中被目标应用授权的容器。Obtain proxy authorization information, which represents the mapping relationship between each application and the proxy server authorized by each application; determine the target proxy server authorized by the target application according to the application identification parameter and the proxy authorization information; Correspondingly, to the target proxy server The address and proxy identification parameters are spliced and processed to generate the target address information of the cross-domain proxy request. The target proxy server may be a proxy server authorized by the target application in the proxy server cluster, and the proxy server cluster may be a cluster formed by each background server of the low-code development platform, and each background server of the low-code development platform provides the proxy service.

在一个示例中，如图8所示，其示例性示出了跨域代理模式下资源访问流程的示意图。其中，低代码开发平台客户端80可以是浏览器前端页面；业务应用程序的实时预览页面81在低代码开发平台客户端80中显示；业务应用程序是指在低代码开发平台下用户需要进行开发的业务应用程序；业务服务器82指按照用户业务逻辑为业务应用程序提供网络服务的服务器，其域名和低代码开发平台客户端80的域名一般不会相同；低代码开发平台服务器83指为低代码开发平台客户端80提供后台服务的服务器，可在这里做业务应用程序的代理服务器，实现低代码开发平台的云端代理功能。低代码开发平台客户端80的域名是lowcode.com，相应地，低代码开发平台服务器83的域名也是owcode.com。业务服务器82的域名为business.com，业务应用程序在实际部署应用时，业务应用程序的域名与业务服务器82的域名相同，都是business.com。但此时，因业务应用程序在低代码开发平台客户端80中调试预览，所以业务应用程序的域名与低代码开发平台客户端80的域名相同，是lowcode.com。用户可在业务应用程序的实时预览页面81执行操作，进而触发业务应用程序的资源访问进程，由业务应用程序生成业务请求，以获取相应的网络资源。若业务应用程序通过低代码开发平台客户端80或者业务应用程序自己直接向业务服务器82发送业务请求，由于浏览器的同源策略限制并且业务服务器82中未设置跨域资源共享配置信息，业务服务器82的响应信息无法发送至业务应用程序。为了解决上述问题，可由低代码开发平台客户端80拦截业务应用程序发送的业务请求，更改业务请求的请求路径为低代码开发平台服务器83中的云端代理接口地址，并保存业务请求的原请求路径，生成代理请求并将代理请求发送至低代码开发平台服务器83。这样便满足浏览器的同源策略，同域名的网络请求的发送不受限制，低代码开发平台服务器83可以顺利接收代理请求。低代码开发平台服务器83接收代理请求后，基于代理请求中的保存的业务请求的原请求路径，向业务服务器发送资源获取请求。由于服务器之间的请求不存在同源策略限制，业务服务器82可顺利接收资源获取请求，并可将响应信息发送至低代码开发平台服务器83。低代码开发平台服务器83接收到响应信息后，便可将响应信息转发至低代码开发平台客户端80中的业务应用程序，这样一来，业务应用程序便可成功访问未经跨域资源共享配置的业务服务器82中的网络资源。In one example, as shown in FIG. 8 , it exemplarily shows a schematic diagram of the resource access process in the cross-domain proxy mode. The low-codedevelopment platform client 80 may be a browser front-end page; the real-time preview page 81 of the business application is displayed on the low-codedevelopment platform client 80; the business application refers to the low-code development platform where the user needs to develop The business application program; thebusiness server 82 refers to the server that provides network services for the business application program according to the user business logic, and its domain name and the domain name of the low-codedevelopment platform client 80 are generally different; the low-codedevelopment platform server 83 refers to the low-code development platform. Thedevelopment platform client 80 provides a server for background services, and can be used as a proxy server for business applications here to realize the cloud proxy function of the low-code development platform. The domain name of the low-codedevelopment platform client 80 is lowcode.com, and correspondingly, the domain name of the low-codedevelopment platform server 83 is also owcode.com. The domain name of thebusiness server 82 is business.com. When the business application program is actually deployed and applied, the domain name of the business application program is the same as the domain name of thebusiness server 82, and both are business.com. However, at this time, since the business application is debugged and previewed in the low-codedevelopment platform client 80, the domain name of the business application is the same as the domain name of the low-codedevelopment platform client 80, which is lowcode.com. The user can perform operations on the real-time preview page 81 of the service application, thereby triggering the resource access process of the service application, and the service application generates a service request to obtain corresponding network resources. If the business application directly sends a business request to thebusiness server 82 through the low-codedevelopment platform client 80 or the business application itself, due to the limitation of the browser's same-origin policy and the cross-domain resource sharing configuration information is not set in thebusiness server 82, the business server A response of 82 could not be sent to the business application. In order to solve the above problems, the low-codedevelopment platform client 80 can intercept the service request sent by the service application, change the request path of the service request to the cloud proxy interface address in the low-codedevelopment platform server 83, and save the original request path of the service request , generate a proxy request and send the proxy request to the low-codedevelopment platform server 83 . In this way, the same-origin policy of the browser is satisfied, the sending of network requests of the same domain name is not restricted, and the low-codedevelopment platform server 83 can smoothly receive the proxy request. After receiving the proxy request, the low-codedevelopment platform server 83 sends a resource acquisition request to the service server based on the original request path of the service request saved in the proxy request. Since there is no same-origin policy restriction on requests between servers, theservice server 82 can successfully receive the resource acquisition request, and can send the response information to the low-codedevelopment platform server 83 . After receiving the response information, the low-codedevelopment platform server 83 can forward the response information to the business application program in the low-codedevelopment platform client 80, so that the business application program can successfully access the non-cross-domain resource sharing configuration network resources in theservice server 82 of the
