WO2012171391A1 - Network resource access optimization method, web browser, and terminal - Google Patents

Abstract

A network resource access optimization method, a Web browser, and a terminal. The method comprises: after receiving a request for accessing a linked file, parsing a path uniform resource locator (URL) of the linked file in a page to obtain an absolute path of the linked file in a service server; detecting whether file data corresponding to the absolute path is buffered; if yes, canceling the request for accessing the linked file; and if no, initiating the request for accessing the linked file. The present invention not only can correctly access a linked file but also can discriminatively process linked files, that is, for the same linked file, even if the paths are different, multiple requests for accessing the file server can be avoided, thereby achieving the purpose of saving network resources and apparatus resources.

Description

 Optimization method for accessing network resources, web browser and terminal

Technical field

 The present invention relates to the field of software applications, and in particular, to an optimization method for accessing network resources, a web browser and a terminal. Background technique

 The Internet has developed rapidly. Its main carrier is HTML pages based on Hyper Text Mark-up Language (HTML) encoded files. In HTML pages, a large number of external links are used, such as: script files (such as JavaScript). File), Cascading Style Sheet (CSS) files, image files (such as bitmap images (BMP) files, Joint Photographic Experts Group (JPEG) files, image interchange formats (Graphics Interchange) Format, GIF) files, Portable Network Graphic Format (PNG) files, and more. In the process of writing a specific page code, the page developer may use the same outer chain file multiple times in the HTML file, but the path of the corresponding outer chain file in the HTML file may be different. For example: test.jpg file in the server home folder, for the test.jpg file in the home folder, the following path of the external link file may appear in the page, respectively: path 1, path 2:

 Path 1 : htt ://127.0.0.1 /home/webserver/, ./test.jpg;

 Path 2: htt ://127.0.0.1 /home/httpserver/../test.jpg;

 The above path 1, path 2 is actually pointing to the test.jpg file in the server home directory, for the terminal, the absolute path of the file is:

 Http :〃127.0.0.1 /home/test.jpg.

However, when parsing the path to the external link file in the terminal browser, it parses into two different Uniform / Universal Resource Locators (URLs), and initiates a resource access request to the service server. Although the general browser will have two URLs with different paths 1 and 2, which are actually pointing to the same external file on the service server, the terminal browser sends two requests to the service server, for the service server resources and the terminal devices. Resources are wasted. When a large number of external file files have the same path and different paths, the large number of terminal devices accessing at the same time can easily cause overload of the service server, which brings certain risks to the system operation. Summary of the invention

 The technical problem to be solved by the embodiments of the present invention is to provide an optimization method for accessing network resources.

The web browser and the terminal are used to avoid multiple requests for access to the service server for the external link files with different paths, thereby saving the network resources and the resources of the device itself.

 Detecting whether the file data corresponding to the absolute path is cached, and if so, canceling the request to access the outer chain file; if not, initiating the request to access the outer chain file.

 The foregoing method further has the following features: after the request for the access to the external link file is initiated, the method further includes:

 The file data corresponding to the outer chain file is downloaded, and the correspondence between the absolute path and the downloaded file data is saved.

 The foregoing method further has the following feature: the step of parsing the absolute path of the outer chain file in the service server from the path URL in the page of the outer chain file includes:

 Determining whether the path URL includes a file path symbol, and if not, using the path URL as an absolute path of the outer chain file in the service server; if yes, performing simplification processing according to the meaning of the file path symbol The absolute path of the outer chain file in the business server.

 The invention also provides a terminal comprising the above web browser.

 2 is a flowchart of an optimization method for accessing network resources according to an embodiment of the present invention. As shown in FIG. 2, the method includes the following steps:

 S201. After receiving the request for accessing the outer chain file, the path from the outer chain file in the page

The absolute path of the outer chain file in the service server is parsed in the URL;

S202. Detect whether the file data corresponding to the absolute path is cached, and if yes, cancel the A request to access an outer chain file; if not, a request to access the outer chain file is initiated.

 The method in this embodiment can avoid the problem of wasting resources by initiating multiple requests to the service server for the external link file with multipath in the web page.

 The embodiment of the present invention recalculates the path URL of the web browser for parsing the outer chain file in the page, for example, simplifying calculation of path symbols such as "../", "./", "//" in the path URL, and calculating The result is an absolute path that does not contain external links such as "../", "./", "//", etc., so that the web browser can detect the data related to the external link file.

 The file caching function is introduced on the terminal side of the web browser, and the data of the external chain file that has been accessed is saved, and the mapping relationship between the outer chain file data and the absolute path of the outer chain file is also saved.

 FIG. 3 is a flowchart of an optimization method for accessing network resources according to an embodiment of the present invention. As shown in FIG. 3, the method includes the following steps:

 Step 301: The web browser receives a request for accessing an external link file.

 Step 302: The web browser parses the web page, and parses the absolute path from the path URL specified by the outer chain file in the page;

 In this step, when the web browser parses the path URL defined by the outer chain file in the page, it is determined whether the path URL has a file path symbol, such as "../" "./" "//", etc., if none of the above If the path symbol does not need to be simplified, the path URL is directly returned. If the path contains the path symbol, the path is simplified according to the meaning of the symbol. The processed path URL is the absolute path of the external link file in the service server. .

 Step 303, the web browser detects whether the file data corresponding to the absolute path has been cached, if the cache has passed, then proceeds to step 304; if there is no cache, then proceeds to step 305;

 Step 304: directly use the cached related file data;

 Step 305: Download related file data, cache the file data after the download is completed, and save the correspondence between the absolute path of the file and the file data for subsequent query.

One of ordinary skill in the art can understand that all or part of the above steps can be completed by a program to instruct related hardware, and the program can be stored in a computer readable storage medium, such as read only. Memory, disk or disc, etc. Alternatively, all or part of the steps of the above embodiments may also be implemented using one or more integrated circuits. Correspondingly, each module/unit in the foregoing embodiment may be implemented in the form of hardware, or may be implemented in the form of a software function module.
