 服务端socket编程

 

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print(\'socket创建成功\')
try:
    s.bind((\'\', 888))
except socket.error as msg:
    print(msg)
    exit()

print(\'socket绑定端口成功\')
s.listen(10)
print(\'socket正在监听\')

while True:
    conn, addr = s.accept()
    print(addr[0]+\'::\'+addr[1], \'客户端连接成功\', )

    data = conn.recv(1024)
    print(\'接收到的数据为\',data)
    if not data:
        break
    conn.sendall(data)

conn.close()
s.close()
