Linux下基于C++语言开发即时通信软件 关键词:聊天软件 文字聊天 Linux平台 C/S架构ICE中间件 Linux-based instant messaging software using C++ language development Abstract Network communication is the computer users to communicate the most common way, all kinds of chat software also emerge in endlessly; Service providers also provide more and more rich communication service functions. The current Chinas Internet technology has entered a rapid development period, instant communication tools as the network application of mainstream, more and more get the favour of people, make people online life more colorful. The most widely used instant communication tools, Microsofts MSN and chat software the tecent company for peoples work and life bring great convenience. Especially for tencent speaking, the companys earnings, a large part is attributed to large clientele, and based on this, expand the other business. The graduation design is simulated chat software, the development of a text chat, group chat function of instant communication software. Using C/S structure, based on Linux platform development, the C++ programming language. From the server and client program composition. The ICE middleware, and remove the server and client coupling. And use QT for the design of the graphical interface. The realization of the main chat software is part of the function, which text chat, the function such as news group, the main task of the module design, including the server text chat, mass news etc. Function. Through the operation, test and analysis, the multifunctional chat software operation is stable, reliable, and has a certain practical value.
