技术领域Technical Field
本申请涉及通信技术领域，特别是涉及一种基于泛域名的多层级代理动态路由方法、装置及系统。The present application relates to the field of communication technology, and in particular to a multi-level proxy dynamic routing method, device and system based on wildcard domain names.
背景技术Background Art
服务的请求转发通常需要依靠代理服务器维护域名与IP地址之间的对应关系来进行路由，例如，此处引述公开号为CN112637346A的专利文件，其公开了一种代理方法、装置、代理服务器及存储介质，当接收到客户端发送的访问请求时，代理服务器获取该访问请求携带的目标域名，并根据预存的域名与IP地址的对应关系，获得目标域名对应的目标IP地址；之后，将访问请求转发给目标IP地址对应的目标业务服务器，以使目标业务服务器响应访问请求返回请求结果；再由代理服务器将请求结果反馈至客户端。The forwarding of service requests usually requires the proxy server to maintain the correspondence between the domain name and the IP address for routing. For example, the patent document with publication number CN112637346A is cited here, which discloses a proxy method, device, proxy server and storage medium. When receiving an access request sent by a client, the proxy server obtains the target domain name carried by the access request, and obtains the target IP address corresponding to the target domain name based on the pre-stored correspondence between the domain name and the IP address; then, the access request is forwarded to the target business server corresponding to the target IP address, so that the target business server responds to the access request and returns the request result; the proxy server then feeds back the request result to the client.
然而，域名通常具有较长的字符串，现有技术维护域名与IP地址之间的对应关系会带来繁重的配置管理或代码修改负担，也不利于开发人员进行访问。However, domain names usually have long character strings. The existing technology for maintaining the correspondence between domain names and IP addresses will bring heavy configuration management or code modification burdens and is not conducive to access by developers.

具体实施方式DETAILED DESCRIPTION
为使本申请的所述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本申请作进一步详细的说明。显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。In order to make the objects, features and advantages of the present application more obvious and understandable, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
发明人通过分析现有技术发现：域名通常具有较长的字符串，维护域名与IP地址之间的对应关系会带来繁重的配置管理或代码修改负担，也不利于开发人员进行访问。同时，对于较为复杂的业务场景，单个服务端（机房）下可以有多个环境，一个环境内可以有多个业务线，故同个服务端下的目标IP地址就有多个，现有技术则会从多个目标IP地址中选一个，并将访问请求转发给选定的目标IP地址对应的目标服务端，而无法直接从域名访问到具体的服务。现有技术在域名配置以及进行访问时的路由过程灵活性均较差。The inventors found through analyzing the prior art that domain names usually have long character strings, and maintaining the correspondence between domain names and IP addresses will bring about a heavy burden of configuration management or code modification, and is not conducive to developer access. At the same time, for more complex business scenarios, a single server (computer room) can have multiple environments, and an environment can have multiple business lines, so there are multiple target IP addresses under the same server. The prior art will select one from the multiple target IP addresses and forward the access request to the target server corresponding to the selected target IP address, and it is impossible to directly access the specific service from the domain name. The prior art has poor flexibility in domain name configuration and the routing process when performing access.
为解决以上技术问题，本申请的核心技术构思之一在于，在多层级业务场景下引入泛域名机制，以泛域名的形式携带多层级的路由信息，从而实现服务的请求转发。泛域名是一种特殊的互联网域名，它被用于指代一个特定领域内的多个子网站或页面。例如，一个企业可以使用泛域名将其不同产品或服务的网页归纳为一个大类，并在该泛域名下建立各自的子域名。泛域名中的通配符可以将所有相关的子域名都串联起来，方便用户访问和管理。To solve the above technical problems, one of the core technical concepts of this application is to introduce a wildcard domain name mechanism in a multi-level business scenario, carrying multi-level routing information in the form of a wildcard domain name, thereby realizing service request forwarding. A wildcard domain name is a special Internet domain name that is used to refer to multiple sub-websites or pages in a specific field. For example, a company can use a wildcard domain name to group the web pages of its different products or services into a large category and establish their own subdomains under the wildcard domain name. The wildcard in the wildcard domain name can connect all related subdomains in series, making it easier for users to access and manage.
需要说明的是，在本申请所公开的实施例中，除非特别限定，任一特征均可被其他等效或具有类似目的的替代特征进行替换；本申请实施例中的特征和/或步骤，除了互相排斥的特征和/或步骤以外，均可以任何方式进行组合。It should be noted that, in the embodiments disclosed in the present application, unless otherwise specified, any feature may be replaced by other alternative features that are equivalent or have similar purposes; the features and/or steps in the embodiments of the present application, except for mutually exclusive features and/or steps, may be combined in any way.

The present application provides a multi-level proxy dynamic routing method, device and system based on wildcard domain names, the method involving a user end, a gateway end, a proxy end and a server end; the gateway end pre-stores a wildcard domain name resolution rule; the gateway end pre-stores a first correspondence between a first domain name segment and proxy address information; the gateway end pre-stores a second correspondence between a second domain name segment and service address information; the user end is used to send an access request to the gateway end; wherein the access request includes a target wildcard domain name; the method includes: when receiving When receiving the access request, the gateway determines the target first domain name segment and the target second domain name segment according to the target wildcard domain name and the wildcard domain name resolution rule; the gateway determines the target proxy address information according to the target first domain name segment and the first corresponding relationship; the gateway determines the target service address information according to the target second domain name segment and the second corresponding relationship; the gateway sends the access request and the target service address information to the proxy through the target proxy address information; the proxy is used to send the access request to the server through the target service address information; the server is used to determine the request result according to the access request, and return the request result to the user. This application solves the problem that the prior art maintains the correspondence between domain names and IP addresses, which is not conducive to developers' access, and achieves the technical effect of realizing request forwarding through multi-level dynamic routing.
下面，将对本示例性实施例中一种基于泛域名的多层级代理动态路由方法作进一步地说明。Next, a multi-level proxy dynamic routing method based on wildcard domain names in this exemplary embodiment will be further described.
需要说明的是，所述网关端可以是一种基于OpenResty框架开发的web运维平台，简称OpenResty运维平台。OpenResty是一个基于Nginx与Lua的高性能Web平台，其内部集成了大量精良的Lua库、第三方模块以及大多数的依赖项。用于方便地搭建能够处理超高并发、扩展性极高的动态Web应用、Web服务和动态网关。OpenResty运维平台可供用户添加域名中特定标识与后端服务地址的对应关系，即可通过这些特定标识唯一确定后端服务的地址，OpenResty运维平台相当于为对应的具体服务自动生成了一个域名，将这些特定标识所代表的路由信息直接放置在一个标准规则下的域名中（对应于OpenResty运维平台的主域名）。OpenResty运维平台能够在进行请求转发前可从泛域名中快速获取到路由信息，进而完成请求的正确转发，因此，用户端需要以泛域名向OpenResty运维平台发起访问请求。It should be noted that the gateway end can be a web operation and maintenance platform developed based on the OpenResty framework, referred to as the OpenResty operation and maintenance platform. OpenResty is a high-performance Web platform based on Nginx and Lua, which integrates a large number of sophisticated Lua libraries, third-party modules and most dependencies. It is used to easily build dynamic Web applications, Web services and dynamic gateways that can handle ultra-high concurrency and high scalability. The OpenResty operation and maintenance platform allows users to add the correspondence between specific identifiers in the domain name and the backend service address, that is, the address of the backend service can be uniquely determined by these specific identifiers. The OpenResty operation and maintenance platform is equivalent to automatically generating a domain name for the corresponding specific service, and placing the routing information represented by these specific identifiers directly in a domain name under a standard rule (corresponding to the main domain name of the OpenResty operation and maintenance platform). The OpenResty operation and maintenance platform can quickly obtain routing information from the wildcard domain name before forwarding the request, and then complete the correct forwarding of the request. Therefore, the user end needs to initiate an access request to the OpenResty operation and maintenance platform with a wildcard domain name.
所述服务端可以与所述网关端部署于同一机房（内网访问），也可以是部署于不同机房（公网访问）。当所述服务端与所述网关端部署于不同机房时，出于安全性考虑，OpenResty运维平台无法直接访问到服务端的所有服务，因此，可以在服务端前部署一个同样是基于OpenResty实现的Proxy代理服务（代理端），由网关端通过IP白名单或者VPN网络访问模式对代理端进行网络安全控制访问。所有请求都是先从网关端转发至代理端上，然后再由代理端转发至服务端具体的后端服务上。The server can be deployed in the same computer room as the gateway (intranet access) or in different computer rooms (public network access). When the server and the gateway are deployed in different computer rooms, for security reasons, the OpenResty operation and maintenance platform cannot directly access all services of the server. Therefore, a Proxy service (agent) based on OpenResty can be deployed in front of the server, and the gateway can perform network security control access to the agent through IP whitelist or VPN network access mode. All requests are first forwarded from the gateway to the agent, and then forwarded by the agent to the specific backend service of the server.
所述第一对应关系和所述第二对应关系表示域名中特定标识与地址信息的对应关系，即，OpenResty运维平台并不直接存储所生成的泛域名与地址信息之间的对应关系，而是对访问请求中的目标泛域名进行解析后动态确定相应的服务地址，以实现动态路由。The first correspondence and the second correspondence represent the correspondence between a specific identifier in a domain name and address information, that is, the OpenResty operation and maintenance platform does not directly store the correspondence between the generated wildcard domain name and address information, but dynamically determines the corresponding service address after resolving the target wildcard domain name in the access request to achieve dynamic routing.
如所述步骤S110所述，当接收到所述访问请求时，所述网关端依据所述目标泛域名和所述泛域名解析规则确定目标第一域名段和目标第二域名段。As described in step S110, when receiving the access request, the gateway determines the target first domain name segment and the target second domain name segment according to the target wildcard domain name and the wildcard domain name resolution rule.
需要说明的是，所述泛域名解析规则可以用于将泛域名划分为第一域名段和第二域名段，以进一步确定代理地址信息和服务地址信息。It should be noted that the wildcard domain name resolution rule can be used to divide the wildcard domain name into a first domain name segment and a second domain name segment to further determine the proxy address information and the service address information.
如所述步骤S120和步骤S130所述，所述网关端依据所述目标第一域名段和所述第一对应关系确定目标代理地址信息；所述网关端依据所述目标第二域名段和所述第二对应关系确定目标服务地址信息；As described in step S120 and step S130, the gateway determines the target proxy address information according to the target first domain name segment and the first corresponding relationship; the gateway determines the target service address information according to the target second domain name segment and the second corresponding relationship;
需要说明的是，所述泛域名可以包括第一域名段、第二域名段以及主域名，第一域名段可以用于确定用于代理端的地址，第二域名段可以用于确定服务端及其具体服务的地址，主域名可以是用户端用于访问网关端的公网域名。It should be noted that the wildcard domain name may include a first domain name segment, a second domain name segment and a primary domain name. The first domain name segment may be used to determine the address used for the proxy end, the second domain name segment may be used to determine the address of the server end and its specific service, and the primary domain name may be the public domain name used by the user end to access the gateway end.
所述第一对应关系为第一域名段与代理地址信息之间的对应关系；当第一域名段为机房名称时，网关端可以依据机房名称和第一对应关系确定该机房（服务端）所对应的代理端，即，网关端并不直接发送访问请求至服务端，而是先发送访问请求至代理端后，由代理端转发至服务端，服务端和代理端是相对应的。The first correspondence is the correspondence between the first domain name segment and the proxy address information; when the first domain name segment is the name of a computer room, the gateway can determine the proxy corresponding to the computer room (server) based on the name of the computer room and the first correspondence, that is, the gateway does not directly send an access request to the server, but first sends the access request to the proxy, which is then forwarded to the server. The server and the proxy correspond to each other.
所述第二对应关系为第二域名段与服务地址信息之间的对应关系；网关端可以依据服务名称和第二对应关系确定服务端机房下具体服务的地址信息，代理端则通过所述服务地址信息进行转发。The second correspondence is the correspondence between the second domain name segment and the service address information; the gateway end can determine the address information of the specific service in the server room according to the service name and the second correspondence, and the proxy end forwards it through the service address information.
上述步骤S120~S130是本实施例下的具体实现方式，可根据实际需求调整步骤S120~S130的先后顺序，上述步骤的顺序不应理解为对本申请的限定。The above steps S120~S130 are specific implementation methods under this embodiment. The order of steps S120~S130 can be adjusted according to actual needs. The order of the above steps should not be understood as a limitation on this application.
如所述步骤S140所述，所述网关端通过所述目标代理地址信息发送所述访问请求和所述目标服务地址信息至所述代理端；所述代理端用于通过所述目标服务地址信息发送所述访问请求至所述服务端；所述服务端用于依据所述访问请求确定请求结果，以及返回所述请求结果至所述用户端。As described in step S140, the gateway sends the access request and the target service address information to the proxy via the target proxy address information; the proxy is used to send the access request to the server via the target service address information; the server is used to determine the request result based on the access request, and return the request result to the user.
需要说明的是，所有对泛域名的解析可以都在所述网关端上进行，所述代理端可以只负责将访问请求原封不动地进行转发；所述服务端可以依次通过所述代理端和所述网关端返回所述请求结果至所述用户端。It should be noted that all resolution of wildcard domain names can be performed on the gateway end, and the proxy end can only be responsible for forwarding the access request intact; the server end can return the request result to the user end through the proxy end and the gateway end in turn.
在本申请一实施例中，所述泛域名解析规则包括域名分隔符和域名段次序；In one embodiment of the present application, the wildcard domain name resolution rule includes domain name separators and domain name segment order;
可以结合下列描述进一步说明步骤S110所述“所述网关端依据所述目标泛域名和所述泛域名解析规则确定目标第一域名段和目标第二域名段”的具体过程。The specific process of "the gateway determines the target first domain name segment and the target second domain name segment according to the target wildcard domain name and the wildcard domain name resolution rule" in step S110 can be further explained in combination with the following description.
如下列步骤所述，所述网关端依据所述目标泛域名确定有效信息字符串；As described in the following steps, the gateway determines a valid information string according to the target wildcard domain name;
所述网关端依据所述有效信息字符串、所述域名分隔符和所述域名段次序确定目标第一域名段和目标第二域名段。The gateway determines the target first domain name segment and the target second domain name segment according to the valid information string, the domain name separator and the domain name segment order.
需要说明的是，有效信息字符串可以表示泛域名中包含有能够确定代理地址信息和服务地址信息的有效部分；域名分隔符可以表示将第一域名段和第二域名段进行分隔的标识符；所述域名段次序可以表示依据排列的次序分别确定第一域名段和第二域名段的规则。It should be noted that the valid information string can indicate that the wildcard domain name contains a valid part that can determine the proxy address information and the service address information; the domain name separator can indicate an identifier that separates the first domain name segment and the second domain name segment; the domain name segment order can indicate the rules for respectively determining the first domain name segment and the second domain name segment according to the order of arrangement.
在本申请一实施例中，可以结合下列描述进一步说明“所述网关端依据所述目标泛域名确定有效信息字符串”的具体过程。In an embodiment of the present application, the specific process of "the gateway determines a valid information string according to the target wildcard domain name" can be further explained in combination with the following description.
如下列步骤所述，所述网关端依据所述目标泛域名去除主域名信息，并截取有效信息字符串。As described in the following steps, the gateway removes the primary domain name information according to the target wildcard domain name and intercepts a valid information string.
需要说明的是，当泛域名中包含主域名时，所述网关端可以先去除主域名信息，再截取有效信息字符串。It should be noted that, when the wildcard domain name includes the primary domain name, the gateway may first remove the primary domain name information and then intercept the valid information string.
在本申请一实施例中，可以结合下列描述进一步说明“所述网关端依据所述有效信息字符串、所述域名分隔符和所述域名段次序确定目标第一域名段和目标第二域名段”的具体过程。In one embodiment of the present application, the specific process of "the gateway determines the target first domain name segment and the target second domain name segment based on the valid information string, the domain name separator and the domain name segment order" can be further explained in combination with the following description.
如下列步骤所述，所述网关端依据所述域名分隔符切分所述有效信息字符串并依次排列确定字符串序列；As described in the following steps, the gateway divides the valid information string according to the domain name separator and arranges them in sequence to determine a string sequence;
所述网关端依据所述字符串序列和所述域名段次序确定目标第一域名段和目标第二域名段。The gateway determines the target first domain name segment and the target second domain name segment according to the character string sequence and the order of the domain name segments.
需要说明的是，字符串序列可以表示切分出的不同域名段，也可以直接表示切分出的机房或具体服务的名称。It should be noted that the string sequence can represent different domain name segments that are segmented, or can directly represent the name of a segmented computer room or specific service.
作为一种示例，当以“server.idc.env.bu.moat.demo.com”作为访问请求的泛域名时，“所述网关端依据所述有效信息字符串、所述域名分隔符和所述域名段次序确定目标第一域名段和目标第二域名段”具体可以包括如下步骤：As an example, when "server.idc.env.bu.moat.demo.com" is used as the wildcard domain name of the access request, "the gateway determines the target first domain name segment and the target second domain name segment according to the valid information string, the domain name separator and the domain name segment order" may specifically include the following steps:
所述网关端去除泛域名中的主域名信息“.moat.demo.com”，截取有效信息字符串“server.idc.env.bu”；The gateway removes the primary domain name information ".moat.demo.com" from the wildcard domain name and intercepts the valid information string "server.idc.env.bu";
所述网关端通过“.”号作为域名分隔符对“server.idc.env.bu”进行切分，得到字符串序列“server”、“idc”、“env”和“bu”；The gateway splits "server.idc.env.bu" by using "." as a domain name separator to obtain a string sequence of "server", "idc", "env" and "bu".
所述网关端以域名段次序确定字符串序列中各域名段的名称：第一位置的“server”表示服务名称，第二位置的“idc”表示机房名称，第三位置的“env”表示环境名称，第四位置的“bu”表示业务线名称。The gateway determines the name of each domain name segment in the character string sequence in order of domain name segments: the "server" in the first position represents the service name, the "idc" in the second position represents the computer room name, the "env" in the third position represents the environment name, and the "bu" in the fourth position represents the business line name.
作为一种示例，当以“server.idc.env.bu.ip.port.moat.demo.com”作为访问请求的泛域名时，可见，相较于泛域名“server.idc.env.bu.moat.demo.com”，泛域名“server.idc.env.bu.ip.port.moat.demo.com”增加了“ip”和“port”两个层级，可以通过域名段次序确定域名段中所指向的服务地址：第五位置的“ip”表示IP地址，第六位置的“idc”表示端口号。As an example, when "server.idc.env.bu.ip.port.moat.demo.com" is used as the wildcard domain name of the access request, it can be seen that compared with the wildcard domain name "server.idc.env.bu.moat.demo.com", the wildcard domain name "server.idc.env.bu.ip.port.moat.demo.com" adds two levels of "ip" and "port". The service address pointed to in the domain name segment can be determined by the order of the domain name segments: the "ip" in the fifth position represents the IP address, and the "idc" in the sixth position represents the port number.
作为一种示例，当以“idc.ip.port.moat.demo.com”作为访问请求的泛域名时，所述网关端可直接通过该域名和第一对应关系确定服务端机房对应的代理端地址后，直接通过域名指定对应的IP地址和端口，这种情况下可以无需预先配置服务名称、环境名称等与真实地址之间的对应关系。As an example, when "idc.ip.port.moat.demo.com" is used as the wildcard domain name of the access request, the gateway can directly determine the proxy address corresponding to the server computer room through the domain name and the first correspondence, and then directly specify the corresponding IP address and port through the domain name. In this case, there is no need to pre-configure the correspondence between the service name, environment name, etc. and the real address.
需要说明的是，在上述的各个泛域名层级中，可以有至少一个层级为空，例如，在“服务名.机房名.环境名.业务线名.主域名”的结构中，“环境名”和“业务线名”可以为空，即表示为目标服务端机房里只有一套环境和一个业务线。对于开发运维人员而言，仅需记忆泛域名的结构，即可直接通过对应的名称对具体的服务进行访问。It should be noted that in each of the wildcard domain name levels mentioned above, at least one level can be empty. For example, in the structure of "service name. computer room name. environment name. business line name. primary domain name", "environment name" and "business line name" can be empty, which means that there is only one environment and one business line in the computer room of the target server. For development and operation and maintenance personnel, they only need to remember the structure of the wildcard domain name and can directly access specific services through the corresponding name.
在本申请一实施例中，所述目标第一域名段包括目标机房名称；In one embodiment of the present application, the target first domain name segment includes the target computer room name;
可以结合下列描述进一步说明“所述网关端依据所述目标第一域名段和所述第一对应关系确定目标代理地址信息”的具体过程。The specific process of "the gateway determines the target proxy address information based on the target first domain name segment and the first corresponding relationship" can be further explained in combination with the following description.
如下列步骤所述，所述网关端依据所述目标机房名称和所述第一对应关系确定目标代理地址信息。As described in the following steps, the gateway determines the target proxy address information according to the target computer room name and the first corresponding relationship.
需要说明的是，可以通过机房名称表示访问请求最终送达的服务端，机房名称和第一对应关系用于确定服务端所对应代理端的地址；服务地址信息由第二域名段和第二对应关系确定，而不直接通过机房名称确定服务端地址。It should be noted that the computer room name can be used to represent the server to which the access request is ultimately delivered, and the computer room name and the first correspondence are used to determine the address of the proxy corresponding to the server; the service address information is determined by the second domain name segment and the second correspondence, rather than directly determining the server address through the computer room name.
在本申请一实施例中，所述目标第二域名段包括目标服务名称、目标环境名称和目标业务线名称；In one embodiment of the present application, the target second domain name segment includes a target service name, a target environment name, and a target business line name;
可以结合下列描述进一步说明“所述网关端依据所述目标第二域名段和所述第二对应关系确定目标服务地址信息”的具体过程。The specific process of "the gateway determines the target service address information based on the target second domain name segment and the second corresponding relationship" can be further explained in combination with the following description.
如下列步骤所述，所述网关端依据所述目标服务名称、所述目标环境名称、所述目标业务线名称和所述第二对应关系确定目标服务地址信息。As described in the following steps, the gateway determines the target service address information according to the target service name, the target environment name, the target business line name and the second corresponding relationship.
需要说明的是，对于较为复杂的业务场景，服务端机房下可以有多个环境，一个环境内可以有多个业务线，故同个服务端可以包含多个服务地址；通过目标服务名称、目标环境名称和目标业务线名称，所述网关端所确定的目标服务地址信息为服务端机房下具体服务的地址信息，所述代理端能够通过目标服务地址信息直接访问到具体的服务实现多层级访问。It should be noted that for more complex business scenarios, there may be multiple environments under the server computer room, and there may be multiple business lines within an environment, so the same server may contain multiple service addresses; through the target service name, target environment name and target business line name, the target service address information determined by the gateway end is the address information of the specific service under the server computer room, and the proxy end can directly access the specific service through the target service address information to achieve multi-level access.
在本申请一实施例中，所述目标第二域名段包括：目标IP地址和目标端口号；In one embodiment of the present application, the target second domain name segment includes: a target IP address and a target port number;
可以结合下列描述进一步说明“所述网关端依据所述目标第二域名段和所述第二对应关系确定目标服务地址信息”的具体过程。The specific process of "the gateway determines the target service address information based on the target second domain name segment and the second corresponding relationship" can be further explained in combination with the following description.
如下列步骤所述，所述网关端依据所述目标IP地址、所述目标端口号和所述第二对应关系确定目标服务地址信息。As described in the following steps, the gateway determines the target service address information according to the target IP address, the target port number and the second corresponding relationship.
需要说明的是，对于目标服务在多个IP下都存在的情况，所述网关端可以直接通过目标IP地址、目标端口号和第二对应关系确定目标服务地址信息，即，可通过IP地址和端口号直接指定服务地址信息，域名中可以不包含服务名称、环境名称和业务线名称，也无需预先配置服务名称、环境名称和业务线名称与服务地址信息的对应关系。It should be noted that in the case where the target service exists under multiple IPs, the gateway can directly determine the target service address information through the target IP address, target port number and the second correspondence, that is, the service address information can be directly specified by the IP address and port number, and the domain name may not contain the service name, environment name and business line name, and there is no need to pre-configure the correspondence between the service name, environment name and business line name and the service address information.
在本申请一实施例中，参照图4-6，所述代理端可以包括至少两个；所述服务端可以包括至少两个；所述代理端和所述服务端可以是一一对应的；所述方法具体可以包括：In an embodiment of the present application, referring to FIGS. 4-6 , the proxy terminals may include at least two; the server terminals may include at least two; the proxy terminals and the server terminals may correspond one to one; the method may specifically include:
所述网关端通过所述目标代理地址信息发送所述访问请求和目标服务地址信息至目标代理端；所述目标代理端用于通过目标服务地址信息发送访问请求至目标服务端；所述目标服务端用于依据所述访问请求确定请求结果，以及通过所述目标代理端和所述网关端返回所述请求结果至所述用户端。The gateway sends the access request and target service address information to the target proxy via the target proxy address information; the target proxy is used to send the access request to the target server via the target service address information; the target server is used to determine the request result based on the access request, and return the request result to the user via the target proxy and the gateway.
需要说明的是，当所述代理端和所述服务端均包括至少两个时，所述方法可以用于跨机房访问，泛域名机制可使得跨机房场景下所有web服务均可生成一套统一规则的域名，实现对一个或多个服务端下的多个散乱的web服务进行集中地访问管理，开发运维人员查询或操作不同机房和环境的web服务时，不再需要频繁地来回切换VPN网络，极大提升工作效率，简化了访问和管理；开发运维人员也不再需要记录繁杂的各种web服务地址，并且所有的web平台数据增删改查都可按预分配的不同用户权限安全的自主进行操作，省去了每次排查问题时都要找运维人员协助的繁琐；排查生产业务问题时，在一个web运维平台上就能完成所有机房的服务运行状态数据获取、日志查询、监控数据查看等，使常用问题分析的工具和手段都集中于一个运维平台上，极大的提升了生产问题的处置效率。It should be noted that when the proxy end and the server end each include at least two, the method can be used for cross-computer room access, and the wildcard domain name mechanism can enable all web services in cross-computer room scenarios to generate a set of domain names with unified rules, thereby realizing centralized access management of multiple scattered web services under one or more servers. When development and operation personnel query or operate web services in different computer rooms and environments, they no longer need to frequently switch back and forth VPN networks, which greatly improves work efficiency and simplifies access and management; development and operation personnel no longer need to record various complicated web service addresses, and all web platform data additions, deletions, modifications and inquiries can be performed safely and independently according to pre-assigned different user permissions, eliminating the tediousness of having to seek assistance from operation and maintenance personnel every time a problem is investigated; when troubleshooting production business problems, service operation status data acquisition, log query, monitoring data viewing, etc. of all computer rooms can be completed on a web operation and maintenance platform, so that the tools and means for common problem analysis are concentrated on one operation and maintenance platform, greatly improving the efficiency of handling production problems.
在一具体实现中，参照图5，OpenResty运维平台可以部署于核心数据中心中；用户可以通过泛域名发起http/tcp访问请求至OpenResty运维平台；对于跨机房（多个数据中心）场景，OpenResty运维平台分别依据泛域名中不同数据中心的机房名称发送访问请求至对应的平台Proxy代理模块：idc_a对应于数据中心A的代理，idc_b对应于数据中心B的代理，idc_c对应于数据中心C的代理；对于数据中心A，平台Proxy代理模块再根据服务名称server_m对后端服务池进行访问；对于数据中心B，平台Proxy代理模块再根据服务名称server_n对后端服务池进行访问；对于数据中心C，平台Proxy代理模块再根据IP地址10.0.0.1以及端口号8080对后端服务池进行访问。In a specific implementation, referring to FIG5 , the OpenResty operation and maintenance platform can be deployed in a core data center; users can initiate http/tcp access requests to the OpenResty operation and maintenance platform through wildcard domain names; for cross-computer room (multiple data centers) scenarios, the OpenResty operation and maintenance platform sends access requests to the corresponding platform Proxy proxy modules according to the computer room names of different data centers in the wildcard domain names: idc_a corresponds to the proxy of data center A, idc_b corresponds to the proxy of data center B, and idc_c corresponds to the proxy of data center C; for data center A, the platform Proxy proxy module accesses the backend service pool according to the service name server_m; for data center B, the platform Proxy proxy module accesses the backend service pool according to the service name server_n; for data center C, the platform Proxy proxy module accesses the backend service pool according to the IP address 10.0.0.1 and the port number 8080.
在一具体实现中，参照图6，所述方法还可以涉及存储端，所述存储端可以为阿里云OSS（对象存储服务），所述目标泛域名可以包括控制指令域名段，所述控制指令域名段对应于shell指令和/或服务分析组件web请求；所述网关端解析出控制指令后将访问请求和控制指令发送至代理端，所述服务端依据访问请求确定请求结果后，将服务运行状态数据上传至阿里云OSS，再由网关端读取阿里云OSS中的服务运行状态数据，即，所述服务端通过所述存储端返回请求结果至所述网关端。In a specific implementation, referring to Figure 6, the method may also involve a storage end, which may be Alibaba Cloud OSS (object storage service), and the target wild-card domain name may include a control instruction domain name segment, which corresponds to a shell instruction and/or a service analysis component web request; after the gateway end parses the control instruction, it sends the access request and the control instruction to the proxy end, and after the server end determines the request result based on the access request, it uploads the service operation status data to Alibaba Cloud OSS, and then the gateway end reads the service operation status data in Alibaba Cloud OSS, that is, the server end returns the request result to the gateway end through the storage end.
在一具体实现中，用户可以使用一个标准的泛域名“http://rocketmq.alifin.moat.iboxpay.com”发起http访问请求，访问请求首先到达OpenResty运维平台网关；OpenResty运维平台网关根据域名中携带的服务名rocketmq、机房名alifin（阿里金融云），将访问请求转发至目标机房阿里金融云的OpenResty Proxy代理服务上；阿里金融云的OpenResty Proxy代理服务再将访问请求原封不动地代理至目标服务rocketmq上。In a specific implementation, a user can use a standard wildcard domain name "http://rocketmq.alifin.moat.iboxpay.com" to initiate an http access request. The access request first reaches the OpenResty operation and maintenance platform gateway; the OpenResty operation and maintenance platform gateway forwards the access request to the OpenResty Proxy service of the target data center Alibaba Financial Cloud based on the service name rocketmq and the data center name alifin (Ali Financial Cloud) carried in the domain name; the OpenResty Proxy service of Alibaba Financial Cloud then proxies the access request intactly to the target service rocketmq.
