socketserver实现并发（Python）

socketserver实现并发原理：给每一个前来链接的客户端开启一个线程执行通信。也就是给每一个连接“配备”了一个管家。

下面用一个简单的示例来演示socketserver实现并发（一个服务端，两个客户端）：

服务器端：

 1 # Author : Kelvin

 3 import socketserver
 4 from socket import *
 5 
 6 ip_conf = ("127.0.0.1", 8888)
 7 buffer_capcity = 1024
 8 
 9 
10 class Mysocket(socketserver.BaseRequestHandler):
11     def handle(self):
12         print(self.request)
13         print(self.client_address)
14 
15         while True:
16             data = self.request.recv(buffer_capcity).decode("utf8")
17             print("服务器收到信息：%s" % data)
18             self.request.send("服务器收到信息！".encode("utf8"))
19 
20 
21 if __name__ == "__main__":
22     s = socketserver.ThreadingTCPServer(ip_conf, Mysocket)
23     s.serve_forever()

客户端一：

 1 # Author : Kelvin
 2 # Date : 2019/2/3 21:51
 3 from socket import *
 4 
 5 ip_conf = ("127.0.0.1", 8888)
 6 buffer_capcity = 1024
 7 client = socket(AF_INET, SOCK_STREAM)
 8 client.connect(ip_conf)
 9 while True:
10     client.send(input("客户端1输入：").encode("utf8"))
11     data = client.recv(buffer_capcity).decode("utf8")
12     print(data)

客户端二：

 1 # Author : Kelvin
 2 # Date : 2019/2/3 21:51
 3 from socket import *
 4 
 5 ip_conf = ("127.0.0.1", 8888)
 6 buffer_capcity = 1024
 7 client = socket(AF_INET, SOCK_STREAM)
 8 client.connect(ip_conf)
 9 while True:
10     client.send(input("客户端2输入：").encode("utf8"))
11     data = client.recv(buffer_capcity).decode("utf8")
12     print(data)
