python之socket编程

单用户连接：

socket_client.py

import socket
client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.connect(('127.0.0.1', 8000))
while True:
    re_data = input()
    client.send(re_data.encode('utf8'))
    data = client.recv(1024)
    print(data.decode('utf8'))

socket_server.py

import socket

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind(('0.0.0.0', 8000))
server.listen()
sock,addr = server.accept()
while True:
    data = sock.recv(1024)
    print(data.decode('utf8'))
    re_data = input()
    sock.send(re_data.encode('utf8'))

多用户连接(利用多线程）

socket_server.py

import socket, threading

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind(('0.0.0.0', 8000))
server.listen()

def handle_sock(sock, addr):
    data = sock.recv(1024)
    print(data.decode('utf8'))
    re_data = input()
    sock.send(re_data.encode('utf8'))

while True:
    sock,addr = server.accept()
    current_thread = threading.Thread(target=handle_sock, args=(sock,addr))
    current_thread.start()
