Description

An optimization method for accessing network resources, a web browser and a terminal

technical field

The invention relates to the field of software applications, in particular to an optimization method for accessing network resources, a Web (web page) browser and a terminal.

Background technique

The Internet is developing rapidly, and its main carrier is HTML web pages based on HTML (Hyper Text Mark-up Language, Hypertext Markup Language) encoded files, and a large number of external link files are used in HTML web pages, such as: script files (such as JavaScript file), CSS (Cascading Style Sheet, Cascading Style Sheet) file, image file (such as BMP (bitmap, bitmap image) file, JPEG (Joint Photographic Experts Group, Joint Photographic Experts Group) file, GIF (Graphics Interchange Format, image Interchange format) files, PNG (Portable Network Graphic Format, streaming network graphics format) files), etc. In the process of writing specific page codes, the page developer may use the same external link file multiple times in the HTML file, but the paths of the corresponding external link files in the HTML file may be different. For example: the test.jpg file is under the home (homepage) folder of the server. For the test.jpg file under the home folder, the following external link file path writing methods may appear on the page, which are recorded as: path 1 and path 2:

Path 1: http://127.0.0.1/home/webserver/../test.jpg;

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

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

http://127.0.0.1/home/test.jpg.

However, when the path of the external link file is parsed in the terminal browser, it is parsed into two different path URLs (Uniform / Universal Resource Locator, Uniform Resource Locator), and a resource access request is initiated to the business server. Although the general browser regards path 1 and path 2 as two different URLs, which actually point to the same external link file on the business server, the terminal browser sends two requests to the business server, which affects the resources of the business server and the terminal equipment. Resources are wasted. When a web file has a large number of external links with the same file but with different paths, simultaneous access by a large number of terminal devices will easily cause the business server to be overloaded and bring certain risks to the system operation.

Parsing module, after receiving the request for accessing the external chain file, resolve the absolute path of the external chain file in the service server from the path URL of the external chain file in the page;

The access processing module is used to detect whether the file data corresponding to the absolute path is cached, and if yes, cancel the request for accessing the external link file; if not, initiate the request for accessing the external link file.

Wherein, after the parsing module receives the request for accessing the external chain file, it is specifically used to judge whether the path URL includes a file path symbol, and if not, use the path URL as the URL of the external chain file in the service server. Absolute path; if there is, simplify the processing according to the meaning of the file path symbol to obtain the absolute path of the external link file in the service server.

In this embodiment, the web server may also include:

The download module is configured to download the file data corresponding to the external link file after the access processing module initiates the request for accessing the external link file.

The caching module is used to save the correspondence between the absolute path and the file data downloaded by the download module.

Wherein, the external link files include one or more of script files, cascading style sheet files and image files.

The present invention also provides a terminal, which includes the above-mentioned Web server.

Fig. 2 is a flow chart of an optimization method for accessing network resources of the present invention, as shown in Fig. 2, the method comprises the following steps:

S10. After receiving the request for accessing the external link file, analyze the absolute path of the external link file in the service server from the path URL of the external link file in the page;

S20. Detect whether the file data corresponding to the absolute path is cached, and if yes, cancel the request for accessing the external link file; if not, initiate the request for accessing the external link file.

The method of the present invention can avoid the problem of resource waste caused by initiating multiple requests to the service server for external chain files with multiple paths in the Web page.

The embodiment of the present invention recalculates the path URL of the external chain file in the page that the Web browser parses, for example, the path symbols such as "../", "./", and "//" in the path URL are simplified and calculated. The result is the absolute path of the external link file that does not contain symbols such as "../", "./", "//", so that the web browser can detect the relevant data of the external link file.

Introduce the file caching function on the terminal side of the web browser, which saves the data of the external link file that has been accessed, and also saves the mapping relationship between the external link file data and the absolute path of the external link file.

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 , including the following steps:

Step 101, the web browser receives a request to access an external link file;

Step 102, the web browser parses the web page, and resolves the absolute path from the path URL specified by the coded external link file in the page;

Specifically, after the web browser parses the path URL defined by the external link file on the page, it judges whether there is a file path symbol in the path URL, such as "../", "./", "//", etc., if there is no such path symbol, the path simplification process is not required, and the path URL is returned directly; if the path contains the above path symbols, the path simplification process needs to be performed according to the meaning of the symbol, and the processed path URL is the absolute path of the external link file in the business server.

Step 103, the web browser detects whether the file data corresponding to the absolute path has been cached, if cached, then turn to step 104; if not cached, then turn to step 105;

Step 104, directly using cached related file data;

Step 105, download relevant file data, cache the file data after the download is completed, and save the absolute path of the file and the corresponding relationship between the file data for subsequent query.
