socket server

#!/usr/bin/env python# -*- coding:utf-8 -*-import socketip_port = ('127.0.0.1',9999)sk = socket.socket()sk.bind(ip_port)sk.listen(5)while True:    print('server waiting...')    conn,addr = sk.accept()    client_data = conn.recv(1024)    print("recv>",client_data.decode('utf-8'))    resp = "我叫天南"    conn.sendall(resp.encode('utf-8'))    print("send>",resp)    conn.close()

socket client

#!/usr/bin/env python# -*- coding:utf-8 -*-import socketip_port = ('127.0.0.1',9999)sk = socket.socket()sk.connect(ip_port)sendstr = "你叫什麼名字？"sk.sendall(sendstr.encode('utf-8'))print("send>",sendstr)server_reply = sk.recv(1024)print("recv>",server_reply.decode('utf-8'))sk.close()

執行結果

client:send> 你叫什麼名字？recv> 我叫天南server:server waiting...recv> 你叫什麼名字？send> 我叫天南server waiting...
