A real-time message-based broadcasting method

Abstract

The present invention relates to the technical field of computer application, and specifically relates to a broadcasting method based on real-time messages. The specific steps are as follows: S1, on the server side, record the cursor B of the last message on the server side into the session; S2, on the client side In the client, the cursor C of the last message displayed in the chat window is also set in the session; S3. The client compares the cursor C of the message with the cursor B of the message on the server: when it is judged that cursor B is not equal to cursor C, At this time, the client has new information, and then executes the operation of reading the message to pull out the message; when it is judged that the cursor B is equal to the cursor C, and the client does not generate a new message at this time, no operation is performed on the server. This method is simple and effective, and can pull the latest news in real time without causing a heavy database load, which not only meets the client's demand for message pulling, but also solves the problem of heavy load on the database.

Description

technical field [0001] The present invention relates to the field of computer application technology, in particular to a broadcasting method based on real-time messages. Background technique [0002] In the existing technical solution, the client requests the server in real time and actively obtains the latest news from the server. The principle is as follows: firstly, the frequency of the information pulling method of the client must be high enough to ensure the timeliness of the data. However, a high frequency will cause a very large system overhead, and the load on the data will increase. The number of executions of the same piece of code per unit time will increase, and not every time the information pulled by the client is the latest and valid content. , the frequency of pulling information may be higher than the update frequency of server messages, which reduces the effective probability of pulling and leads to an increase in network traffic. On the other hand, low fre...

Problems solved by technology

[0005] Therefore, the present invention proposes a broadcasting method based on real-time messages, which is used to solve the problem that the existing technology has a large overhead on the server, the database load is too large, and the speed of pulling messages from the server is uncontrollable.
