Broadcasting method based on real-time message

Abstract

The invention relates to the computer application technology field and especially relates to a broadcasting method based on a real-time message. The method comprises the following steps of S1, in a server side, recording a cursor B of a last message in the server side in a session; S2, in a client side, setting a cursor C of the last message displayed in a chat window into the session; S3, comparing the cursor C of the message with the cursor B of the message of the server side by the client side: when the cursor B is determined not to be equal to the cursor C, and at the same time, a new message is generated on the client side, executing operation of reading the message and pulling the message; and when the cursor B is determined to be equal to the cursor C, and at the same time, the newmessage is not generated on the client side, carrying out nothing on the server side. The method is simple and effective, the newest message can be pulled in real time and a database load is not large, a client demand for message pulling is satisfied, and a problem of the large database load is solved.

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 prior art solution, the client requests the server in real time, and actively obtains the latest information from the server. The principle is as follows: First, the frequency of the information pull method of the client must be high enough to ensure the timeliness of the data. However, the high frequency will cause the system overhead to be very large, and the load on the data will increase. The same piece of code is executed more often in a unit of time and not every time the client pulls the information that is the latest and effective 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, pulling server infor...

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.
