Python两台电脑实现TCP通信的方法示例

# -*- encoding: utf-8 -*-
import socket
 
IP = "192.168.1.153" #服务器端可以写"localhost"，可以为空字符串""，可以为本机IP地址
port = 40005 #端口号
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((IP,port))
s.listen(1)
print('listen at port :',port)
conn,addr = s.accept()
print('connected by',addr)
 
while True:
  data = conn.recv(1024)
  data = data.decode()#解码
  if not data:
    break
  print('recieved message:',data)
  send = raw_input('return:')#python27要写raw_input,python3.X可写input
  conn.sendall(send.encode())#再编码发送
 
 
conn.close()
s.close()

# -*- encoding: utf-8 -*-
import socket
import sys
IP = '192.168.1.153' #填写服务器端的IP地址
port = 40005 #端口号必须一致
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
  s.connect((IP,port))
except Exception as e:
  print('server not find or not open')
  sys.exit()
while True:
  trigger = raw_input("send:")
  s.sendall(trigger.encode())
  data = s.recv(1024)
  data = data.decode()
  print('recieved:',data)
  if trigger.lower() == '1':#发送1结束连接
    break
s.close()
