Problems solved by technology

[0003] Most AJAX requests are dynamically generated by executing dynamic code in the browser. Traditional proxies achieve the purpose of proxy by replacing the statically identifiable complete request address. These dynamically generated addresses cannot be recognized, and cannot be found in the source code of the web page. Find the address of the request, which makes it difficult for the proxy to function

Embodiment

[0032] (1) Experimental environment

[0033] The current environment adopts the reflow mode. An agent program is deployed on a server. Only when the agent program is running can the Internet be accessed normally, otherwise the external network cannot be accessed. Deploy the shunt program on another server, the client is deployed on the server, and the virtual machine with the operating system installed normally accesses the Internet through the browser.

[0034] (2) Experiment and result analysis

[0035] After entering the user name, the login box on Alipay’s homepage can dynamically trigger an AJAX request according to webpage events, and then verify whether the entered account exists or is valid. This function is currently adopted when entering login information on most websites. After the user enters the account information, the AJAX request is triggered without reloading or other changes in the webpage. The execution code executes the request through the XMLHttpRequest o...

Abstract

The invention belongs to the field of computer networks and data communication and mainly relates to a WEB proxy method based on the AJAX support. The method includes the steps that webpage source code information sent by a server is received by a system; the AJAX is found and called, a request method is created according to a prototype mechanism, and an original inner request method is replaced; modified content is sent to a client side and a modified AJAX request executed by a client side browser is sent to a proxy system; a proxy extracts a real request address from the request address of the AJAX request sent by the client side and requests data from the server. In order to solve the problem that the request that a dynamic code of the AJAX is dynamically generated can not be effectively represented is solved, the method for rewriting the packaged internally-arranged method is designed on the basis of the prototype mechanism, the purpose of request address modification is achieved, and the proxy function of the AJAX dynamic request is achieved.

Description

technical field [0001] The invention belongs to the field of computer network and data communication, and mainly relates to a WEB agent method based on supporting AJAX. Background technique [0002] With the introduction of the Internet 2.0 concept, AJAX technology has become an important way to request web page information. Since AJAX is based on asynchronous loading, it is not necessary to reload the entire web page when requesting data, and the browser will not be blocked until the end of the request like a synchronous request. When the requested data is returned, the webpage is dynamically adjusted according to the execution result, which significantly improves the loading speed of the webpage. [0003] Most AJAX requests are dynamically generated by executing dynamic code in the browser. Traditional proxies achieve the purpose of proxy by replacing the statically identifiable complete request address. These dynamically generated addresses cannot be recognized, and canno...
