Python——socketserver编程(客户端/服务器)
一、socketserver是标准库中的高级模块,它的目标是简化很多多样板代码,是创建网络客户端和服务器所必须的代码。(事件驱动)
二、模块类
BaseServer :包含核心服务器功能和mix-in类的钩子,可以用TCPServer或UDPserver创建类的实例
TCPserver/UDPserver:基础的TCP/UDP服务器
UnixStereamServer/UnixDatagramServer:基于文件的TCP/UDP服务器
ForkingMixIn/ThreadingMixIn:核心派出或线程功能
ForkingTCPServer/ForkingUDPServer:ForkingMixIn和TCPServer/UDPServer的组合
ThreadingTCPServer/ThreadUDPServer:ThreadingMixIn和TCPServer/UDPServer的组合
BaseRequestHandler:处理服务请求的核心功能
StreamRequestHandler/DatagramRequestHandler:实现TCP/UDP服务器的服务处理
三、TCP服务器
from socketserver import TCPServer as TCP, StreamRequestHandler as SRH from time import ctime Host = "" Post = 21567 Addr = (Host,Post) class MyRequestHandler(SRH): def handle(self): print ('...connectde from:',self.client_address) self.wfile.writr('[%s]%s'%(ctime(),self.rfile.readline())) tcpServ = TCP(Addr,MyRequestHandler) print ('waiting for connection ...') tcpServ.server_forever()
四、TCP客户端
from socket import * Host = 'localhost' Post = 21567 Bufsiz = 1024 Addr =(Host,Post) while True: tcpCliSock = socket(AF_INET,SOCK_STREAM) tcpCliSock.connect(Addr) data = raw_input('>') if not data: break tcpCliSock.Send('%s\r\n'%data) data = tcpCliSock.recv(Bufsiz) if not data: break print (data.strip()) tcpCliSock.close()
