版本:python 2.7.3 开发工具:IDLE (Python GUI)和Eclipse Pydev 服务器端代码:
- # -*- coding: cp936 -*-
- import socket
- sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)#初始化socket
- sock.bind(("127.0.0.1", 8001))#绑定本机地址,8001端口
- sock.listen(5)#等待客户连接
- while True:
- print "waiting client connection..."
- connection,address = sock.accept()#接收客户连接请求
- print "a client have connected..."
- while True:
- try:
- connection.settimeout(5) #设置超时时间
- buf = connection.recv(1024) #接收数据
- if buf == "1":
- connection.send("you have send me 1!welcome to server!")
- elif buf=="2":
- connection.send("you have send me 2!I have recv!")
- elif buf=="3":
- connection.send("close the connection!")
- break
- else:
- connection.send("unknow command!")
- except socket.timeout:
- print "time out"
- connection.close()
- print "a client exit..."
客户端代码:
- import socket
- sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
- sock.connect(("127.0.0.1", 8001))
- import time
- time.sleep(2)
- while True:
- data=raw_input("input command:");
- sock.send(data)
- print sock.recv(1024)
- if data=="3":
- break
- sock.close()
实验过程: 在Eclipse编程环境下,上述代码运行没有任何的问题。但是在IDLE中,首次运行‘Run Model’时也能正常运行。运行结果如下: [img1]

[img2]

但是,当服务器程序再次运行时,会出现如下错误: [img3]

此时,是因为sock绑定失败,原因是因为第一次运行的窗口进程没有关闭!在任务管理器中,找到进程pythonw.exe关闭,然后再次运行正常!
注:IDLE代码整理的快捷键:和matlab很像,选中一段代码,Ctrl+[ 向左边缩进 Ctrl+] 向右边缩进。Python语法是强制缩进的 源代码下载地址:http://download.csdn.net/detail/nuptboyzhb/4929631
