python网络编程——实现简单聊天
通过socket建立简单的聊天工具
server.py
import socketimport threading
import time
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('ip.*.*.*', 9999))
s.listen(5)
print('Waiting for connection...')
def tcplink(sock, addr):
print('Accept new connection from %s:%s...' % addr)
sock.send(b'Welcome!')
while True:
data = sock.recv(1024)
time.sleep(1)
if not data or data.decode('utf-8') == 'exit':
break
print('Client:%s'%data.decode('utf-8'))
sock.send(('Server:%s'% input()).encode('utf-8'))
sock.close()
print('Connection from %s:%s closed.' % addr)
while True:
# 接受一个新连接:
sock, addr = s.accept()
# 创建新线程来处理TCP连接:
t = threading.Thread(target=tcplink, args=(sock, addr))
t.start()
client.py
import sockets = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# 建立连接:
s.connect(('ip.*.*.*', 9999))
# 接收欢迎消息:
print(s.recv(1024).decode('utf-8'))
while True:
msg=input()
# 发送数据:
s.send(msg.encode('utf-8'))
print(s.recv(1024).decode('utf-8'))
if msg =='exit':
break
s.send(b'exit')
s.close()
