Embodiment Construction

[0025] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] The embodiment of the present invention provides a method and device for network cross-domain access, the method includes: the cross-domain access management module sends the access request to the cross-domain proxy service module running on the same device as the browser, and the access request is An access request to the domain corresponding to the second domain name sent by a script program running inside the browser, the script program is a script program running in a web page corresponding to the first domain name; the cross-domain proxy service module verifies all the legiti...

Abstract

The invention provides a method and device for accessing data by crossing network domains in order to solve the technical problem that the prior art is time consuming and labor consuming. The method comprises that: a cross-domain access management module transmits an access request to a cross-domain proxy service module which runs on a same device with a browser; the cross-domain proxy service module verifies the validity of the access request; if the access request is valid, the cross-domain proxy service module forwards the access request to a domain corresponding to a second domain name and returning the result of accessing the domain corresponding to the second domain name to a cross-domain access management module; and the cross-domain access management module returns the result of accessing the domain corresponding to the second domain name to a script. On one hand, because the cross-domain proxy service module runs on the same device with the browser, which avoids the modification on the accessed target domain and the Web server and simplifies the realization process of cross-domain access. On the other hand, the method of the invention for realizing the cross-domain access has a wide application.

Description

technical field [0001] The invention belongs to the field of computer networks, in particular to a method and device for network cross-domain access. Background technique [0002] JavaScript is a dynamically typed, weakly typed, prototype-based literal scripting language with built-in support for types. The JavaScript interpreter is called the JavaScript engine, which is part of the browser and is widely used as a client-side scripting language. The JavaScript source code does not need to be compiled before being sent to the client to run, but the character code in text format is sent to the browser to be interpreted and run by the browser. [0003] However, similar to the weaknesses of other literal languages, JavaScript is also less secure. Based on the above-mentioned weaknesses of JavaScript, the browser has strict restrictions on the network access of JavaScript programs running inside it. The data of the network under the domain name, that is, the cross-domain acces...
