浏览器与Server交互：

import socket

def handle_request(client):
    buf = client.recv(1024)
    client.send('HTTP/1.1 200 OK\r\n\r\n')

def main():
    #创建socket对象
    socketServer = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    #监听端口
    socketServer.bind(('127.0.0.1',8001))
    #开始监听
    socketServer.listen(5)

    while True:
        #阻塞，deng...
        #直到有请求连接
        print '.'*30
        connection,address = socketServer.accept()
        #connection,代表客户端socket对象
        #address，客户端地址
        #handle_request(connection)
        buf = connection.recv(1024)
        print buf
        connection.send('HTTP/1.1 200 OK\r\n\r\n')
        connection.send('Hello World')
        connection.close()

if __name__ == '__main__':
    main()

Client与Server交互：
Client端：

import socket

socket_client = socket.socket()
socket_client.connect(('127.0.0.1',8009))
socket_client.settimeout(5)

while True:
    inp = raw_input('please input:')
    socket_client.sendall(inp)
    res_size = socket_client.recv(1024)
    print 'going to recv data size:',res_size,type(res_size)
    total_size = int(res_size)
    receive_size = 0
    while True:
        data = socket_client.recv(1024)
        receive_size+=len(data)
        print '---data---'
        if total_size == receive_size:
            print data
            print '---not data---'
            break
        print data
    if inp == 'exit':
        break
socket_client.close()

单线程Server:

import socket

socketServer = socket.socket()
socketServer.bind(('localhost',8341))
socketServer.listen(5)
while True:
    print 'waiting...'
    conn,addr = socketServer.accept()
    #最多接受size
    client_data = buf = conn.recv(1024)
    print client_data
    conn.send('wo shi fu wu duan')
    conn.close()

多线程Server：

import SocketServer
import os

class MyServer(SocketServer.BaseRequestHandler):
    def handle(self):
        # print self.request,self.client_address,self.server
        # conn = self.request #每一个客户端
        print 'get connection from',self.client_address
        while True:
            data = self.request.recv(1024)
            print "Recv from [%s] cmd :%s"%(self.client_address,data)
            cmd_res = os.popen(data).read()
            self.request.send(str(len(cmd_res)))
            self.request.sendall(cmd_res)

if __name__ == '__main__':
    server = SocketServer.ThreadingTCPServer(('127.0.0.1',8009),MyServer)
    server.serve_forever()
