python 套接字实现本机通信

tcp服务器端

from socket import *
from time import ctime

HOST = ''
PORT = 2567
BUFSIZE = 1024
ADDR = (HOST, PORT)
tcpServer = socket(AF_INET, SOCK_STREAM)
tcpServer.bind(ADDR)
tcpServer.listen(5)

while True:
    print("waiting connection")
    tcpClisock, addr = tcpServer.accept()
    print('accept from:', addr)

    while True:
        #从客户端接收过来的信息是二进制形式的
        data = tcpClisock.recv(BUFSIZE)
        if not data:
            break
        #发送信息，该信息必须是二进制字符串的形式，也就是send里面的参数
        tcpClisock.send('[%s] %s'.encode('utf-8') % (bytes(ctime(),'utf-8'), data))
    tcpClisock.close()
tcpServer.close()

tcp客户端

from socket import *
HOST = '127.0.0.1'
PORT = 2567
BUFSIZE = 1024
ADDR = (HOST, PORT)
Clisocket = socket(AF_INET, SOCK_STREAM)
Clisocket.connect(ADDR)

while True:
    data = input('> ')
    if not data:
        break
    #发送的信息必须是二进制
    Clisocket.send(data.encode(encoding='utf-8'))
    data = Clisocket.recv(BUFSIZE)
    if not data:
        break
    print(data)
Clisocket.close()
