Matlab（Client）和Python（Server）进行TCP通信

Posted 2021-01-24 xnlzz

import socket
import time
#IPV4,TCP协议
sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
#绑定ip和端口，bind接受的是一个元组
sock.bind((‘172.23.23.89‘,54378))
#设置监听，其值阻塞队列长度，一共可以有5+1个客户端和服务器连接
sock.listen(5)

a=[1,2,3,4]

while True:

    # 将发送数据转化为String
    s=str(a)
    # 等待客户请求
    connection,address = sock.accept()

    # 打印客户端地址
    print("client ip is:",address)
    # 接收数据,并存入buf
    buf = connection.recv(40960)
    print(buf.decode(‘utf-8‘))

    # 发送数据
    connection.send(bytes(s, encoding="utf-8"))
    # 关闭连接
    connection.close()
    time.sleep(1)
 # 关闭服务器
sock.close()
