An instant messaging method and system based on xmpp protocol

Abstract

The invention relates to an instant messaging method and system based on the XMPP protocol. The method includes the following steps: S1, the sending end generates an instant message and a first verification code, and sends them to the server; S2, the server generates a re-verification code, judges whether the first verification code and the re-verification code are the same, generates a receipt information and sends it to the sending end ; S3, the sender judges whether to send again, if yes, send it again and return to S2, otherwise send the execution command to the server, and execute S4; S4, the server sends the re-check code and instant message to the receiver; S5, the receiver generates a final check code, determine whether the re-inspection code and final-inspection code are the same, generate corresponding receipt information and send it to the server; S6, the server judges whether to send it again, if yes, send it again and return to S5, otherwise end. The invention realizes improving the integrity and safety of data in the process of instant messaging.

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
