总结一下之前写的一个python聊天程序

本文从WordPress迁移而来, 查看全部WordPress迁移文章

一直没空，今天翻出来，总结一下，虽然都是比较基础的东西，但还是记录一下吧….

一：程序的功能

1.服务器与客户端通信，客户端与客户端通信
2.服务器和客户端都可以显示在线的客户，客户上线，下线，可以实时刷新
3.基于第2点，在通信的时候，无论是服务器还是客户端，都可以选择和一人或多人通信

二：开发环境

1.环境：win7，python2.7,PyQt4
2.使用python的socket模块，threading模块
3.PyQt4开发图形界面(用designer布置控件，不是手写)

三：设计思路

  • 服务器

    1. 主线程负责图形界面等
    2. 创建一个线程负责监听客户的连接请求
    3. 没当有客户端成功连接，就又创建一个线程，专门负责和该用户通信

  • 客户端

    1. 主线程负责图形界面等
    2. 创建一个线程负责连接服务器，当连接失败或中断后，可以自动重复连接

四：使用的QT控件

QWidget
QGroupBox
QTextBrowser
QTextEdit
QListWidget
QPushButton

五：发送，接收信息自定义的协议

  • 服务器发送信息：
    1. 服务器发给客户端：FS>信息内容
    2. 服务器接收A客户端信息，发给B客户端：FA客户端地址>信息内容
  • 服务器接收信息：
    1. 客户端发给服务器的信息：TS>信息内容
    2. A客户端发给B客户端的信息（经服务器中转）：TB客服端地址>信息内容
  • 客户端发送信息：
    1. 发送给服务器： TS>信息内容
    2. 发送给客户端： T对方地址>信息内容
  • 客户端接收信息：（其实都是服务器发过来的，一种是服务器直接发送，一种是服务器转发其他客户端的信息）
    1. 接收来自服务器的信息：FS>信息内容
    2. 接收客户端的信息：F对方地址>信息内容

六：问题

  1. 处理异常的方面做得不好
  2. 多线程方面考虑的东西太少
  3. find那个功能没有做，懒得做了。。。。以后把这个程序写得更丰富的时候再做了
  • 服务器程序MyServer.py

由designer布置控件后，用PyQt4的命令自动生成的代码(其实使用的是同一个界面，只是做了稍微的修改….)
