至于知识点相关的内容，这里就不多说了。
udp方式
服务器端
# coding:utf-8 # __author__ = 'mark sinoberg' # __date__ = '2016/7/7' # __desc__ = 创建一个简单的套接字监听请求 import socket host = '192.168.59.255' port = 9998 s = socket.socket(socket.af_inet,socket.sock_dgram) s.bind(('',port)) print '套接字已启动！' while true: data,addr = s.recvfrom(1024) print addr,str(' : ')+data
客户端
# coding:utf-8 # __author__ = 'mark sinoberg' # __date__ = '2016/7/7' # __desc__ = socket的客户端的简单实现 import socket port = 9998 host = '192.168.59.255' s = socket.socket(socket.af_inet,socket.sock_dgram) words = raw_input('client:') while words != 'quit': s.sendto(words,(host,port)) words = raw_input('client:') s.close()
是不是很简单啊。我们需要注意的就是socket的第二个参数为sock_dgram。因为这和tcp方式的sock_stream 有所不同。
tcp方式
服务器端
# coding:utf-8 # __author__ = 'mark sinoberg' # __date__ = '2016/7/7' # __desc__ = 简单的tcpsocket的实现 from socket import * from time import ctime host = '' port = 9999 buffersize = 1024 address = (host,port) s = socket(af_inet,sock_stream) s.bind(address) s.listen(5) while true: print 'waiting for clients cennect!' tcpclient,addr = s.accept() print 'connected by ',addr while true: try: data = tcpclient.recv(buffersize) except exception,e: print e.message tcpclient.close() break if not data: print "no data received!" break senddata = 'hi,you send me:[%s]%s'%(ctime(),data.encode('utf8')) tcpclient.send(senddata.encode('utf8')) print addr,' says:',ctime(),data.encode('utf8') tcpclient.close() s.close()
客户端
# coding:utf-8 # __author__ = 'mark sinoberg' # __date__ = '2016/7/7' # __desc__ = 简单的tcp socket客户端的实现 from socket import * class tcpclient: # host = 'localhost' port = 9999 host = '192.168.59.225' buffsiz = 1024 addr = (host,port) def __init__(self): self.client = socket(af_inet,sock_stream) self.client.connect((self.host,self.port)) while true: senddata = raw_input('>>>') if not senddata: print 'please input some words!\n>>>' continue if senddata == "quit": break self.client.send(senddata.encode('utf8')) recvdata = self.client.recv(self.buffsiz) if not recvdata: break print recvdata.encode('utf8') if __name__ == "__main__": client = tcpclient()
tcp方式演示结果：(注意先开启服务器端)
服务器端
d:\software\python2\python.exe e:/code/python/mytestset/sockettest/simpletcpserver.py
waiting for clients cennect!

('192.168.59.225', 63095) says: thu jul 07 16:01:15 2016 haode

waiting for clients cennect!
客户端
d:\software\python2\python.exe e:/code/python/mytestset/sockettest/simpletcpclient.py
>>>hello world
hi,you send me:[thu jul 07 16:01:10 2016]hello world
>>>
please input some words!

>>>haode
hi,you send me:[thu jul 07 16:01:15 2016]haode
>>>quit
process finished with exit code 0
总结
简单的使用tcp或者是udp确实很容易，然而要想更好的利用这两个协议，就需要好好的设计一番了。
这里我想强调的是，注意tcp和udp创建套接字时指定的参数即可。
