Python Socket

 无论是tcp协议的socket还是udp协议的socket,都是通过socket.socket(socket.AF_INET,socket.SOCK_STREAM/SOCK_DGRAM) 创建

第一个参数一般都是填写socket.AF_INET

第二个参数

Tcp: SOCK_STREAM

Udp:SOCK_DGRAM

 简单代码:

client.py

import socket
import time

if __name__=='__main__':
    sock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    addr=('localhost',2000)
    sock.connect(addr)
    time.sleep(2)
    try:
        while True:
            sock.send(raw_input('>>'))
            buff=sock.recv(1024)
            print 'get: %s    %s' % (buff,time.ctime())
    except Exception,e:
        print "Error:",e
        sock.close()

services.py

　　

import socket
import datetime

if __name__=='__main__':
    sock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    sock.bind(('127.0.0.1',2000))
    sock.listen(5)
    while True:
        connection,address=sock.accept()
        connection.settimeout(10000)
        while True:
            try:
              buf=connection.recv(1024)
              print 'get: %s   %s' % (buf,datetime.datetime.now())
              if buf=='exit':
                    break
              connection.send(raw_input('>>'))
            except socket.timeout:
                print 'time out'
                connection.close()

Udp协议与tcp协议差不多,只是关键字不同而已
