Method and system for barrier-free information push on basis of HTTP (hyper text transport protocol)

Abstract

The invention provides a method and a system for barrier-free information push on the basis of a HTTP (hyper text transport protocol). The method includes S1, acquiring a GET request message of the HTTP in a network; S2, judging whether information push is completed or not according to a source address of the GET request message, and entering a step S3 if the information push is not completed; S3, judging whether the content of pushed information is accessed or not according to parameters in a URL (uniform resource locator) of the GET request message, and entering a step S4 if the content of the pushed information is not accessed; S4, constructing a URL containing the information required to be pushed and redirection mark parameters according to information configured by a user; S5, forging a redirection reply of the HTTP and simultaneously resetting TCP (transmission control protocol) connection; S6, reconstructing the URL constructed in the step S4, and deleting the redirection mark parameters; S7, forging a redirection reply of the HTTP and simultaneously resetting TCP connection; S8, releasing the GET request message; S9, completing periodic information push; and S10, completing fixed-point information push. By the method and the system, the information required to be pushed can be assuredly pushed to the user for online browsing, and accordingly barrier-free information push is realized.

Description

【Technical field】 [0001] The invention relates to an HTTP-based barrier-free information push method and system, belonging to the field of information push. 【Background technique】 [0002] Existing information push technologies all use HTTP302 redirection. When the user goes online (online for the first time, or is forced to go offline after a certain period of time and then goes online after no action), the specified information is pushed. [0003] However, due to the use of HTTP302 redirection, it is impossible to accurately distinguish whether the request is sent by the HTTP application or the browser, so that it is impossible to ensure that the user sees the information that needs to be pushed, and it is impossible to push specific information to online users at a specific time, for example, It is impossible to push information such as real-time notifications to online users. At the same time, the existing information push technology also has the problem that a single ...

[0003] However, due to the use of HTTP302 redirection, it is impossible to accurately distinguish whether the request is sent by the HTTP application or the browser, so that it is impossible to ensure that the user sees the information that needs to be pushed, and it is impossible to push specific information to online users at a specific time, for example, It is impossible to push real-time notifications and other information to online users

At the same time, the existing information push technology still has the problem that the single push information cannot push different information at each time point
