Cross-domain network resource request method and device for client

Abstract

The invention discloses a cross-domain network resource request method and a cross-domain network resource request device for a client. The method comprises the following steps: receiving an asynchronous webpage request transmitted by the client with a first server, wherein the asynchronous webpage request carries a network resource address of a second server, and the first server and the client belong to a first domain; acquiring a server flag bit in the asynchronous webpage request; if the server flag bit indicates that the second server belongs to a second domain, extracting the network resource address and generating a network resource request by the first server, wherein the first domain is different from the second domain; forwarding the network resource request to the second server; transmitting the received response data of the second server to the client, wherein the response data carries the network resource corresponding to the network resource address. According to the method and the device, the problems that a cross-domain network resource request operation in the prior art is fussy and low in efficiency are solved; the effect of accessing cross-domain network resource quickly and efficiently by the client is achieved.

Description

technical field [0001] The present invention relates to the Internet field, in particular to a method and device for a client to request network resources across domains. Background technique [0002] At present, the arrival of the second generation of Internet Web 2.0 has made AJAX technology widely used, and the core of AJAX technology is the JavaScript object XmlHttpRequest, which is a technology that supports asynchronous requests. Users can use JavaScript to make requests to the server and get Responsive, while not affecting the use of other users. However, in practice, AJAX technology interacts with data through XMLHttpRequest objects. When users need to access page content in other domains, browsers do not allow JS codes to perform cross-domain operations for security reasons. In view of the above problems, the current solutions are as follows: [0003] Solution 1: JSONP method: use HTML script tags to load and execute other domain JavaScript files. Site B passes t...
