#Python 网络编程-TCP服务端基础篇（一）简单的发送和接收
##TCP服务端基本流程图

TCP服务端-单个客户端

import socket
_BUFFSIZE = 1024
ip_addr = r"10.110.36.27"
port = 9000
ip_port = (ip_addr,port)
socket_server = socket.socket()
socket_server.bind(ip_port)
socket_server.listen()
print("正在等待客户端连接")
conn,addr = socket_server.accept()
print("当前连接的ip",addr)
while 1:
print("正在等待接收信息")
receive_msg = conn.recv(_BUFFSIZE)
print("接收到的信息为",receive_msg.decode())
if 'quit' in receive_msg.decode():
break
# send_msg = input("请输入要发送的信息")
conn.sendall(receive_msg)
socket_server.close()

TCP服务端-多个客户端(二)

import threading
import time
import re

_MAX_CLIENT = 5
ip_addr = r"10.110.36.27"
port = 9000
ip_port = (ip_addr,port)
# socket_server = socket.socket()
# socket_server.bind(ip_port)
# socket_server.listen(_MAX_CLIENT)
# print("正在等待客户端连接")

# conn,addr = socket_server.accept()
# print("当前连接的ip",addr)

            receive_msg = conn.recv(_BUFFSIZE)
            print("来自%s的信息为%s"%(addr,receive_msg))
            if receive_msg.decode() =='':
                break
            else:
                if 'quit' in receive_msg.decode():

        print("关闭连接：",addr)
        conn.close()

    def client_listen(self,conn,addr):
        thread_1 = threading.Thread(target=self.receive_send,args=(conn,addr,))
        thread_1.start()

try:
    server_obj = TcpServer(ip_addr,port)
    server_obj.serve_start()
    server_obj.con_info()
    # server_obj.client_listen()
finally:
    server_obj.serve_stop()
