Page push method, apparatus and system, and information obtaining method and apparatus

Abstract

The embodiment of the invention provides a page push method, apparatus and system, and an information obtaining method and apparatus, and relates to the field of data communication. The page push method comprises the following steps: a proxy server receives a second network access request sent by a terminal based on the address information of the proxy server; and the proxy server returns a middlepage to the terminal based on the second network access request, so that the terminal obtains identification information based on the middle page. After the proxy server receives the second network access request sent by the terminal based on the address information of the proxy server, the proxy server returns the middle page to the terminal based on the second network access request, so that the terminal obtains identification information based on the middle page, therefore the terminal is identified, the corresponding Portal page is pushed to the identified terminal subsequently to performdifferent access permission control, so that the network security is improved, the application range is wider, the expandability is higher, and the hardware system requirements are lower.

Description

technical field [0001] The present invention relates to the field of data communication, in particular, to a page pushing method, device, system, and information acquisition method and device. Background technique [0002] With the rapid development of computer and Internet technology, governments, banks, enterprises and other units have deployed wireless or wired networks for employees and visitors. For security and other reasons, the above wireless networks are not completely open networks and require You can access the Internet only after authentication and authorization. At present, there are two main access authentication and authorization methods. One is enterprise-level 802.1x encryption authentication, and the other is semi-open Portal authentication. The former requires a one-time input of a valid user name and The password is used for authentication and cannot interact with the user. The latter interacts with the user through the Portal page, which can realize the ...

Problems solved by technology

[0004] The existing solution to obtain terminal information is to obtain terminal information through the User-Agent attribute in the http request, and then use the obtained terminal information to accurately deliver the push page when the user accesses the network, which has the following shortcomings: theoretically, it cannot It is compatible with the information collection of all terminals; the User-Agent parameter in the http request can be modified, and the push page cannot be delivered accurately, and can deceive the authentication server to obtain improper access rights, which brings hidden dangers to network security
