socket(): 创建一个套接字
bind()：绑定IP和端口
listen()：监听
accept()：接收请求
connect()：请求连接建立
write()：发送
read()：接收
close():关闭连接
socket通信示例：
服务器端tcpserver.py
#/usr/bin/pythonimport socketHOST=‘127.0.0.1‘PORT=9527BUFFER=4096sock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)sock.bind((HOST,PORT))sock.listen(3)print(‘tcpServer listen at: %s:%s\n\r‘ %(HOST,PORT))while True:client_sock,client_addr=sock.accept()print(‘%s:%s connect‘ %client_addr)while True:recv=client_sock.recv(BUFFER)if not recv:client_sock.close()breakprint(‘[Client %s:%s said]:%s‘ %(client_addr[0],client_addr[1],recv))client_sock.send(‘tcpServer has received your message‘)sock.close()客户端tcpclient
#/usr/bin/pythonimport socketHOST=‘127.0.0.1‘PORT=9527BUFFER=4096sock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)sock.connect((HOST,PORT))sock.send(‘hello, tcpServer!‘)recv=sock.recv(BUFFER)print(‘[tcpServer said]: %s‘ % recv)sock.close()执行下面命令测试
python tcpserver
phthon tcpclient
httpd服务和apache
