Instant messaging method and system based on XMPP protocol

Abstract

The invention relates to an instant messaging method and an instant messaging system based on an XMPP protocol. The method comprises the steps as follows: S1, a sending end generates an instant message and a primary check code, and sends the instant message and the primary check code to a server; S2, the server generates a re-check code, judges whether the primary check code and the re-check code are identical, and generates receipt information and sends the same to the sending end; S3, the sending end judges whether to send again, if yes, resending and returning to the step S2 are performed, and otherwise, an execution command is sent to the server, and the step S4 is executed; S4, the server sends the re-check code and the instant message to a receiving end; S5, the receiving end generates a final check code, judges whether the re-check code and the final check code are identical, and generates corresponding receipt information and sends the same to the server; and S6, the server judges whether to resend, if yes, resending and returning to the step S5 are performed, and otherwise the method ends. According to the method and the system provided by the invention, completeness and security of data during an instant messaging process are improved.

Description

technical field [0001] The invention belongs to the field of instant messaging, in particular to an instant messaging method and system based on the XMPP protocol. Background technique [0002] XMPP (Extensible Messaging and Presence Protocol) is a protocol based on XML (Extensible Markup Language, Extensible Markup Language), which is used for IM (Internet Message, Instant Messaging) and online presence detection. It facilitates quasi-instant operations between servers. The protocol may eventually allow Internet users to send instant messages to anyone else on the Internet, even if those Internet users have different operating systems and browsers. [0003] The existing instant messaging based on the XMPP protocol has the following defects: [0004] The prerequisite for realizing instant messaging based on the XMPP protocol is that the connection between the client and the server is stable, but due to various reasons, the stability of the connection between the client and...

AI Technical Summary

Problems solved by technology

[0004] The prerequisite for realizing instant messaging based on the XMPP protocol is that the connection between the client and the server is stable, but due to various reasons, the stability of the connection between the client and the server is difficult to guarantee;

[0005] The client includes the sending end and the receiving end. When the message is transmitted, the integrity and security of the transmitted message will be poor due to the disconnection between the client and the server.

[0006] The message is sent from the sender, passes through the server, and consumes too much traffic when it reaches the receiver, which is a serious waste of resources
