一种浏览器及其进行域名解析的方法A browser and its method for domain name resolution

技术领域technical field

本发明涉及互联网技术领域，具体涉及一种浏览器及其进行域名解析的方法。The invention relates to the technical field of the Internet, in particular to a browser and a domain name resolution method thereof.

背景技术Background technique

目前，浏览器在访问指定的URL（UniformResourceLocator，统一资源定位符）时，获得该URL的根内容，解析该根内容，建立相应的网络请求。可见，现有方案是等用户输入网址才解析，且下载根URL后，分析HTML（超文本标记语言，HypertextMarkupLanguage）数据内容，然后才根据需要渲染的对象进行下载。其中，在下载需要渲染的对象之前需要进行解析DNS，然而，DNS解析的时间可能从几个毫秒到100秒之间，所以，当采用现有方案访问一个URL，消耗的时间比较长。Currently, when a browser accesses a specified URL (UniformResourceLocator, Uniform Resource Locator), it obtains the root content of the URL, parses the root content, and establishes a corresponding network request. It can be seen that the existing solution is to wait for the user to input the URL before parsing, and after downloading the root URL, analyze the HTML (Hypertext Markup Language, HypertextMarkupLanguage) data content, and then download according to the object to be rendered. Among them, DNS needs to be resolved before downloading the object to be rendered. However, the DNS resolution time may range from a few milliseconds to 100 seconds. Therefore, when using the existing solution to access a URL, it takes a relatively long time.

为了解决DNS解析耗时的问题，目前存在几种DNS预取技术，具体为：In order to solve the time-consuming problem of DNS resolution, there are currently several DNS prefetching technologies, specifically:

1)通过meta信息告知浏览器需要做DNS预取。如：<metahttp-equiv=″x-dns-prefetch-control″content=″on″/>；1) Inform the browser that DNS prefetching needs to be done through meta information. Such as: <metahttp-equiv=″x-dns-prefetch-control″content=″on″/>;

2)使用Link标签强制做DNS预取。如：<linkrel=″dns-prefetch″href＝″http://some-web-site.com″/>；2) Use the Link tag to force DNS prefetching. Such as: <linkrel=″dns-prefetch″href=″http://some-web-site.com″/>;

3)在地址栏发生变化时，猜测相关后缀，如当用户输入www.sina时，就猜测输入www.sina.com，www.sina.org,www.sina.gov等域名。3) When the address bar changes, guess the relevant suffix, such as when the user inputs www.sina, guess and input www.sina.com, www.sina.org, www.sina.gov and other domain names.

然而，上述DNS预取技术中，需要指定Link标签，对于目前大量现存的网页，不能解决DNS加速问题。另外，若仅为了DNS加速而升级网页，也不划算，并且对于不需要的连接进行预读取，浪费了网络资源，增加了网络流量费用。However, in the above-mentioned DNS prefetching technology, it is necessary to specify a Link tag, which cannot solve the problem of DNS acceleration for a large number of existing web pages. In addition, it is not cost-effective to upgrade webpages only for DNS acceleration, and pre-reading unnecessary connections wastes network resources and increases network traffic costs.

实施例三Embodiment Three

本发明实施例提供一种浏览器进行域名解析的方法，该方法是对实施例一和实施例二所述方法的进一步详细阐述，具体包括：An embodiment of the present invention provides a method for a browser to perform domain name resolution. The method is a further detailed elaboration of the methods described in Embodiment 1 and Embodiment 2, and specifically includes:

一，DNS加速数据信息生成步骤；1. DNS acceleration data information generation steps;

当在在服务器侧生成时，包括：When generated on the server side, include:

1）搜集主域名，并利用搜集到的主域名配置主域名池；1) Collect primary domain names, and use the collected primary domain names to configure the primary domain name pool;

其中，搜集主域名配置主域名池的方式包括但不限于为：接收用户侧上报的各主域名，和/或，获取全网热点域名信息，利用访问量前N位主域名配置所述主域名池；所述N为正整数。Among them, the method of collecting primary domain names to configure the primary domain name pool includes but is not limited to: receiving the primary domain names reported by the user side, and/or obtaining the hotspot domain name information of the entire network, and using the top N primary domain names to configure the primary domain names pool; said N is a positive integer.

2）在主域名池内逐一选取各主域名，拦截系统函数getaddrinfo()，获取对应主域名对应的二级子域名，以及主域名与各二级子域名的IP地址信息。2) Select each main domain name one by one in the main domain name pool, intercept the system function getaddrinfo(), obtain the second-level sub-domain name corresponding to the main domain name, and the IP address information of the main domain name and each second-level sub-domain name.

该步骤中，拦截的系统函数为getaddrinfo(constchar*nodename,constchar*service,conststructaddrinfo*hints,structaddrinfo**result)函数。In this step, the intercepted system function is the getaddrinfo(constchar*nodename, constchar*service, conststructaddrinfo*hints, structaddrinfo**result) function.

其中，nodename：待解析的域名(ASCII格式）；service：包含服务名称或端口的ANSI字符串；hints：网络socket提示数据结构，指明网络协议族、socket类型、协议等；result：解析返回数据结构，用来保存系统解析的数据。Among them, nodename: the domain name to be parsed (ASCII format); service: the ANSI string containing the service name or port; hints: the network socket prompt data structure, indicating the network protocol family, socket type, protocol, etc.; result: the parsed return data structure , used to save the data parsed by the system.

如果getaddrinfo函数返回成功，那么由result参数指向的变量已被填入一个指针，它指向的是由其中的ai_next成员串联起来的addrinfo结构链表。可以导致返回多个addrinfo结构的情形有以下两个：If the getaddrinfo function returns successfully, the variable pointed to by the result parameter has been filled with a pointer, which points to the addrinfo structure linked list concatenated by its ai_next members. There are two situations that can cause multiple addrinfo structures to be returned:

1，与nodename参数关联的地址有多个，那么适用于所请求地址簇的每个地址都返回一个对应的结构。1. If there are multiple addresses associated with the nodename parameter, a corresponding structure is returned for each address applicable to the requested address cluster.

2，service参数指定的服务支持多个套接口类型，那么每个套接口类型都可能返回一个对应的结构，具体取决于hints结构的ai_socktype成员。2. The service specified by the service parameter supports multiple socket types, and each socket type may return a corresponding structure, depending on the ai_socktype member of the hints structure.

本发明实施例，在拦截getaddrinfo函数前，先分配一个hints结构，把它清零后填写需要的字段，再拦截getaddrinfo（）函数，获取相应主域名对应的二级子域名、以及所述主域名与各二级子域名对应的套接口地址结构，再根据套接口地址结构，得到主域名和各二级子域名对应的IP地址信息。In the embodiment of the present invention, before intercepting the getaddrinfo function, first allocate a hints structure, clear it and fill in the required fields, and then intercept the getaddrinfo() function to obtain the secondary sub-domain name corresponding to the corresponding main domain name and the main domain name The socket address structure corresponding to each second-level subdomain name, and then according to the socket address structure, the IP address information corresponding to the main domain name and each second-level subdomain name is obtained.

本发明实施例利用getaddrinfo（）函数可以将主机名和服务名转换成套接口地址结构的技术特性，获取了主域名池内各主域名对应的二级子域名，以及各域名对应的IP地址信息。The embodiment of the present invention utilizes the technical characteristics that the getaddrinfo() function can convert the host name and service name into a socket address structure, and obtains the secondary sub-domain names corresponding to each main domain name in the main domain name pool, and the corresponding IP address information of each domain name.

3）将获取的各主域名及其对应的二级子域名，以及主域名与各二级子域名的IP地址信息保存到DNS加速数据信息中。3) Save the obtained main domain names and their corresponding second-level sub-domain names, as well as the IP address information of the main domain names and each second-level sub-domain names, into the DNS acceleration data information.

该步骤中，在保存主域名及其对应的二级子域名时，建立主域名与对应的各二级子域名间映射关系的map表，具体映射关系如图3所示。In this step, when saving the main domain name and its corresponding second-level sub-domain names, a map table of the mapping relationship between the main domain name and each corresponding second-level sub-domain name is established, and the specific mapping relationship is shown in FIG. 3 .

当在在浏览器侧生成时：所述DNS加速数据信息为浏览器统计用户访问的URL而获取的DNS加速数据信息。When generated on the browser side: the DNS acceleration data information is the DNS acceleration data information acquired by the browser to collect statistics on the URLs accessed by the user.

其中，所述浏览器获取DNS加速数据信息的方式包括：Wherein, the manner in which the browser acquires DNS acceleration data information includes:

获取用户访问的URL，提取该URL对应的主域名；Obtain the URL accessed by the user, and extract the main domain name corresponding to the URL;

拦截系统函数getaddrinfo()，获取所述主域名对应的二级子域名、以及所述主域名与各二级子域名对应的套接口地址结构；Intercepting the system function getaddrinfo() to obtain the secondary sub-domain name corresponding to the main domain name and the socket address structure corresponding to the main domain name and each secondary sub-domain name;

根据所述套接口地址结构，得到主域名和各二级子域名对应的IP地址信息；According to the socket address structure, the IP address information corresponding to the main domain name and each secondary sub-domain name is obtained;

将所述主域名、所述主域名对应的各二级子域名、以及各域名对应的IP地址信息存入DNS加速数据信息中。其中，在保存主域名及其对应的二级子域名时，建立主域名与对应的各二级子域名间映射关系的map表，具体映射关系继续如图3所示。The primary domain name, the secondary sub-domain names corresponding to the primary domain name, and the IP address information corresponding to each domain name are stored in the DNS acceleration data information. Wherein, when storing the main domain name and its corresponding second-level sub-domain name, a map table of the mapping relationship between the main domain name and each corresponding second-level sub-domain name is established, and the specific mapping relationship continues to be shown in FIG. 3 .

二，DNS加速步骤；Two, DNS acceleration steps;

1，启动浏览器，调用DNS加速数据信息；1. Start the browser and call DNS to accelerate data information;

其中，调用的DNS加速数据信息为在服务器侧下载的DNS加速数据信息，或者，为接收到的服务器侧主动推送的DNS加速数据信息，和/或，调用的DNS加速数据信息为浏览器统计用户访问的URL而获取的DNS加速数据信息。Wherein, the DNS acceleration data information called is the DNS acceleration data information downloaded on the server side, or is the DNS acceleration data information actively pushed by the server side received, and/or, the DNS acceleration data information called is the browser statistics user The DNS acceleration data information obtained by visiting the URL.

2，当浏览器地址栏发生变化时，即用户发起了对某URL的访问请求，解析该访问请求，获取待访问的URL；2. When the address bar of the browser changes, the user initiates an access request to a certain URL, parses the access request, and obtains the URL to be accessed;

其中，地址栏发生变化是指用户在地址栏输入或由地址栏自动推荐的URL。Wherein, the change in the address bar refers to the URL input by the user in the address bar or automatically recommended by the address bar.

3，判断待访问的URL是否为系统已经缓存过的URL，若是，说明URL对应的对象未过期，可以直接使用本地系统缓存的信息，此时就不用进行DNS加速处理了；若否，则执行步骤4；3. Determine whether the URL to be accessed is a URL that has been cached by the system. If it is, it means that the object corresponding to the URL has not expired, and the information cached by the local system can be used directly. At this time, there is no need to perform DNS acceleration processing; if not, execute Step 4;

4，分割URL，得到该URL对应的域名，并在DNS加速数据信息中搜索该域名，当搜索到时，执行步骤5；若未搜索到，按正常访问流程处理。4. Split the URL to obtain the domain name corresponding to the URL, and search for the domain name in the DNS acceleration data information. When found, perform step 5; if not found, follow the normal access process.

例如，当用户在浏览网页时，会点击主域名下的二级域名的连接，这时会获取到该二级域名并进行URL的分割，根据上述DNS加速数据信息内的map表，进行分割后的主域名、二级域名的映射关系的查找。For example, when a user browses a webpage, he will click on the link of the second-level domain name under the main domain name. At this time, the second-level domain name will be obtained and the URL will be divided. According to the map table in the above-mentioned DNS acceleration data information, after segmentation Search for the mapping relationship between the primary domain name and the secondary domain name.

5，调用DnsAccelerate()函数，将待加速域名插入到加速列表中。5. Call the DnsAccelerate() function to insert the domain name to be accelerated into the acceleration list.

该步骤具体为：The steps are specifically:

DnsAccelerate()函数调用Windows系统函数QueueUserWorkItem()，通知队列守护线程有域名待加速。The DnsAccelerate() function calls the Windows system function QueueUserWorkItem() to notify the queue daemon thread that there is a domain name to be accelerated.

队列守护线程调用ParallelGetAddrInfoProc()函数，执行如下操作：The queue daemon thread calls the ParallelGetAddrInfoProc() function to perform the following operations:

调用CreateSemaphore函数，创建信号量；Call the CreateSemaphore function to create a semaphore;

调用::QueueUserWorkItem(GetAddrInfoSysProc,&pParseDataArray[index],0)，解析域名；该函数的调用过程即为在DNS加速数据信息中搜索待加速域名对应的IP地址的过程；Call ::QueueUserWorkItem(GetAddrInfoSysProc,&pParseDataArray[index],0) to resolve the domain name; the calling process of this function is the process of searching the IP address corresponding to the domain name to be accelerated in the DNS acceleration data information;

等待所有队列中的任务完成。Wait for all queued tasks to complete.

6，当域名加速完成后，获取到待访问URL对应的IP地址信息，利用该IP地址信息进行访问处理；6. After the domain name acceleration is completed, obtain the IP address information corresponding to the URL to be accessed, and use the IP address information for access processing;

7，当用户浏览所述URL对应的网页时，检测用户鼠标是否在当前浏览的网页上悬停，若是，获取鼠标悬停位置对应的网页分区DIV元素；其中，鼠标悬停示意图如图4所示；7. When the user browses the web page corresponding to the URL, detect whether the user mouse hovers over the currently browsed web page, and if so, obtain the DIV element of the web page section corresponding to the mouse hover position; wherein, the mouse hover schematic diagram is shown in Figure 4 Show;

8，将所述DIV元素内各URL进行分割，得到各URL对应的域名，并对得到的域名进行去重处理；8. Divide each URL in the DIV element to obtain the domain name corresponding to each URL, and perform deduplication processing on the obtained domain name;

9，检测DNS加速数据信息中是否包含各所述URL对应的域名，若包含，则提取各域名对应的IP地址信息，并在用户访问所述DIV元素内的URL时，直接利用所述提取的IP地址信息进行访问处理。9. Detect whether the domain name corresponding to each of the URLs is included in the DNS acceleration data information, and if so, extract the IP address information corresponding to each domain name, and directly use the extracted IP address information when the user accesses the URL in the DIV element. IP address information for access processing.

对于鼠标悬停方案举例说明如下：An example of the mouse hover scheme is as follows:

检测鼠标的当前位置，以及鼠标所覆盖在网页元素中的子元素的URL链接。例如鼠标当前处在<divclass=″nav_2″>Detect the current position of the mouse, and the URL link of the sub-element in the web page element covered by the mouse. For example, the mouse is currently in <divclass="nav_2">
