Problems solved by technology

[0007] Because the web-based instant messaging technology adopts the http protocol, the connectionless and stateless nature of http makes it difficult to manage the online status of instant messaging users and has a large delay
[0008] In addition, web-based instant messaging technology has one-way: only the client (web browser) actively contacts the server, but the server cannot actively contact a user
Therefore, the sending and receiving of messages may cause information loss and delay

Embodiment Construction

[0054] See figure 1 , The operation of the Web instant messaging method of the present invention adopts the server push technology, and the user does not need to install any browser plug-ins when using it; because the technology adopted is based on the HTTP protocol, it can easily traverse the firewall restrictions and is suitable for any operating system; all instant messages Both sending and receiving are asynchronous (AJAX), which improves user experience and reduces the amount of interaction. To use the system, the user must have a unique identification code.

[0055] figure 1 Clients of several users access the server through the gateway. Messages can be sent and received between the user and the gateway, and between the gateway and the server. The server can obtain the status of the user by accessing the gateway. In the figure, the first user is the sender of the instant message, the first user is connected to the server through the first gateway, the second user is the rec...

Abstract

The invention discloses a Web instant messaging method which comprises the steps of: a, sending an instant message to a server by a first user; b, forwarding the instant message to a second gateway registered by a second user if the second user registers the Web, or storing the instant message into a database in an off-line message way if the second user does not register the Web; c, returning the off-line message to a client end of the second user through the second gateway when the second user is changed into the register state from the non-register state, and accessing the second gateway by the client end of the second user to obtain the instant message when the second user is in the register state; and d, if getting the instant message, displaying the instant message to the second user, if not, returning to the step c until the second user leaves the Web. By updating the state information of the user state, the Web instant messaging method solves the problem of delay of managing the on-line state of the user, and greatly lowers the possibility of information loss and delay in processes of sending and receiving the message.

Description

Technical field [0001] The invention relates to Internet Web instant communication technology. technical background [0002] Nowadays, most instant messaging technologies are based on application programs, usually using tcp / ip protocol, corresponding application software must be installed when using, and it is easy to be restricted by firewalls and operating systems. The web-based instant communication method adopts the http protocol, which has the advantages of cross-operating system, immediate use without downloading and installing software, and no firewall influence (port 80: general firewall does not make any restrictions). There are roughly three existing web-based instant messaging technologies: [0003] 1. Based on the browser plug-in (ActiveX), it is relatively stable, but requires the user's permission, download and installation, and is easily intercepted by security software. At the same time, it is restricted by the browser and needs to develop different browser version...
