python基于tcp/ip协议的服务端(支持多个客户端同时连接处理)

代码如下:

 1 import threading
 2 import socket
 3 
 4 
 5 class Server(object):
 6     """服务端"""
 7 
 8     def __init__(self):
 9         self.server_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
10         self.Address = ("192.168.67.102",7890)
11         self.server_socket.bind(self.Address)
12         self.server_socket.listen(128)
13         self.clientsocket = dict()
14         self.count = 0
15         self.isrunning = dict()
16 
17     def WaitClient(self):
18         while True:
19             print("正在等待客户端的连接......")
20             clientsocket,clientAddresss = self.server_socket.accept()
21             print("%s已经连接成功！" % str(clientAddresss))
22             # print(clientsocket,clientAddresss)
23             self.count += 1
24             self.clientsocket[clientAddresss] = clientsocket
25             print("当前客户端连接个数为：%d" % self.clientsocket.__len__())
26             self.isrunning[self.count]=True
27             print("集合中的元素为:%s" % str(self.isrunning.__len__()))
28             t = threading.Thread(target=self.RecvMsg,args = (clientsocket,clientAddresss,self.isrunning,self.count))
29             t1 = threading.Thread(target=self.SendMsg,args=(clientsocket,clientAddresss,self.isrunning,self.count))
30             t.start()
31             t1.start()
32 
33     def RecvMsg(self,client,clientaddress,isrun,count):
34         if isrun[count] is True:
35             while True:
36                 try:
37                     recvmsg = client.recv(1024)
38                     print("来自%s的消息为：%s" % (str(clientaddress),recvmsg.decode("utf-8")))
39                 except Exception as ret:
40                     print("客户端%s已经离去！" % str(clientaddress))
41                     client.close()
42                     isrun[count] = False
43                     self.clientsocket.pop(clientaddress)
44                     break
45         else:
46             return
47 
48     def SendMsg(self,client,clientAddresss,isrun,count):
49             while True:
50                 sendstr = input("请输入你要发送的消息:")
51                 if isrun[count] is True: # 先判断该客户端是否还在
52                     if client:
53                         client.send(sendstr.encode("utf-8"))
54                     else:
55                         isrun.pop(count)
56                         return
57 
58 
59 
60 def main():
61     """测试函数"""
62     S = Server()
63     S.WaitClient()
64 
65 if __name__ == '__main__':
66     main()

客户端代码如下:

import socket
import threading


class Client(object):
    """客户端"""

    def __init__(self):
        self.client_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
        self.Address = ("192.168.67.102",9090)
        self.client_socket.bind(self.Address)
        self.server_Address = ("192.168.67.102",7890)

    def ConnectionServer(self):
        print(self.client_socket)
        self.client_socket.connect(self.server_Address)
        print("连接成功！")
        t1 = threading.Thread(target=self.SendMsg)
        t2 = threading.Thread(target=self.RecvMsg)
        t1.start()
        t2.start()


    def RecvMsg(self):
        while True:
            recvstr = self.client_socket.recv(1024)
            print("接收到来自服务器的消息维为：%s" % recvstr.decode("utf-8"))

    def SendMsg(self):
        while True:
            sendstr = input("请输入你要发送的消息：")
            self.client_socket.send(sendstr.encode("utf-8"))

def main():
    """测试函数"""
    C = Client()
    C.ConnectionServer()
    

if __name__ == '__main__':
    main()
