python简单的socket 服务器和客户端

(安西)

　　服务器端代码
　　


if "__main__" == __name__:
try:
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM);
print("create socket succ!");
sock.bind(('localhost', 8001));
print("bind socket succ!");
sock.listen(5);
print("listen succ!");
except:
print("init socket err!");
while True:
print("listen for client...");
conn, addr = sock.accept();
print("get client");
print(addr);
conn.settimeout(5);
szBuf = conn.recv(1024);
print("recv:" + szBuf);
if "0" == szBuf:
conn.send('exit');
else:
conn.send('welcome client!');
conn.close();
print("end of sevice");

 　　客户端代码
　　


#!/usr/bin/env python
import socket;
if "__main__" == __name__:
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM);
sock.connect(('localhost', 8001));
sock.send('0');
szBuf = sock.recv(1024);
print("recv " + szBuf);
sock.close();
print("end of connect");
