Rich text format realization system and method based on expanded XMPP (xml based messaging and presence protocol)

Abstract

The invention provides a rich text format realization system and a rich text format realization method based on an expanded XMPP (xml based messaging and presence protocol). The system comprises a client and a server end, wherein the client comprises an encoding and decoding module, a text receiving and sending module and an image receiving and sending module, the encoding and decoding module is used for encoding and decoding instant messages, the text receiving and sending module is used for sending and receiving the text messages, the picture receiving and sending module is used for sending and receiving image information, the server end comprises a message receiving and sending processing module, an off-line message module and an image management module, the message receiving and sending processing module is used for receiving and transferring instant messages from the client, the off-line message module is used for temporarily storing the text messages, and the picture management module is used for storing and managing the picture information. The system and the method provided by the invention have the advantages that expansibility and intercommunity are good, the separated picture and text sending is realized, the message passage blockage caused by over size pictures is prevented, the base64 coding is adopted for sending the pictures in the instant messages, and the efficiency is relatively higher.

Description

technical field [0001] The invention belongs to the field of computer network communication, and in particular relates to a rich text format realization system and method based on the extended XMPP protocol. Background technique [0002] Instant Messaging (IM) communication is a real-time Internet communication method. [0003] At present, there are many mainstream IM software in our country, and each has many specific users. For example: Tencent's QQ, Microsoft's MSN and Yahoo's Yahoo Manager and so on. They each use their own different protocol formats and communication technologies for their own commercial interests. The non-uniformity and non-disclosure of this agreement restricts the development of IM software to a large extent. [0004] Considering the openness and interoperability of IM applications, some organizations are working on the design and standardization of general IM protocols. At present, the general IM protocols mainly include the following types: XMP...

Therefore, this is not suitable for ordinary users who have less strict requirements on the format of messages

[0017] At the same time, if the picture is sent in the message, when the picture is relatively large, the length of the message will be very long; if the network condition is not very good, the message channel may be blocked, and the user experience is not good
