SSE (server-sent event) specification-based message push method and device

Abstract

The present invention discloses an SSE (server-sent event) specification-based message push method and device. The method comprises the following steps that: an SSE long connection is built between a server and a terminal; whether a message to be pushed exits is monitored in real time; when it is monitored that a message to be pushed exits, the message to be pushed is sent to the terminal. According to the above method, since the SSE specification is a lightweight protocol, the SSE specification is not required to be deployed additionally compared with the Websocket protocol, at the same time, the technology of the SSE specification is relatively simple compared with that of the Websocket protocol, and requirements for developers are low; since the SSE specification supports one-way communication between the server side and the terminal, that is, as long as a new message exists at the server side, the new message can be pushed to the terminal, the terminal does not need to perform polling, and thus, the real-time push of the message can be ensured; and a connection between the server side and the terminal is a long connection, and therefore, bandwidth can be saved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for pushing messages based on the SSE specification. Background technique [0002] With the continuous development of network technology, it has become an indispensable part of people's daily life to obtain information from the Internet. In order to better provide users with information, pushing messages to users has gradually become an increasingly important way, such as , to push the news that happened that day to the user. [0003] At present, since existing terminal applications are usually developed based on html5, the existing message push method is mainly implemented based on html5. [0004] There are two main ways to push messages. One is to use the Websocket protocol to push messages to the terminal in real time when the messages on the server end change. The other is to use short connection polling, that is, The terminal will send an up...

Problems solved by technology

[0006] The embodiment of the present application provides a message push method and device based on the SSE specification, which is used to solve the complex technology brought by the message push using the Websocket protocol in the prior art, and has high requirements for developers, and the Websocket protocol is heavy Level protocol, the problem of additional deployment, and the waste of bandwidth brought by message push using short connection polling, and the problem of real-time push of messages cannot be guaranteed
