tcp_server.py

tcp_client1.py
# coding:utf-8 from socket import * client = socket() ip_port = ("127.0.0.1", 8080) client.connect(ip_port) while 1: inp = input(">>>:").strip() if not inp: continue client.send(inp.encode("utf-8")) from_server_msg = client.recv(1024) print("來自服務端的消息:", from_server_msg) client.close()
tcp_client2.py和tcp_client1.py代碼完全一樣.
