Python进阶篇：Socket多线程

1. 初识Socket

server和clinet之间的交互方式

2. 客户端和服务端的单次交互

 ====================================
 服务端

 import socket

 host = '127.0.0.1'
 port = 8090
 sk=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
 sk.bind((host,port))
 sk.listen(1)

 conn,addr = sk.accept()
 accept_data = conn.recv(1024).decode('UTF-8', 'ignore')
 print(accept_data)
 feedback_data =("回复\""+accept_data+"\":\n\t你好，我是Server端").encode("utf8")
 conn.send(feedback_data)

 ======================================
 客户端

 import socket

 host = '127.0.0.1'
 port = 8090

 sk=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
 sk.connect((host,port))

 sk.sendall(("你好，我是Client @Simple").encode("utf8"))
 data = sk.recv(1024)
 print(data.decode('UTF-8', 'ignore'))

3. 客户端和服务端单线程交互

 服务端

 import socket

 host = '127.0.0.1'
 port = 8090
 sk=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
 sk.bind((host,port))
 sk.listen(1)

 while True:
     conn,addr = sk.accept()
     while True:
         accept_data = conn.recv(1024).decode('UTF-8', 'ignore')
         if not accept_data:
             break
         print(accept_data)
         feedback_data =("回复\""+accept_data+"\":\n\t你好，我是Server端").encode("utf8")
         conn.sendall(feedback_data)

     conn.close()

 客户端

 import socket,time

 host = '127.0.0.1'
 port = 8090

 sk=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
 sk.connect((host,port))

 for i in range(10):
     sk.sendall(("你好，我是Client No.%d" %i).encode("utf8"))
     data = sk.recv(1024)
     print(data.decode('UTF-8', 'ignore'))
     time.sleep(2)
     i = i + 1
 sk.close()

4. 多个客户端和服务端的多线程交互

 服务端

 import socketserver

 class myTCPhandler(socketserver.BaseRequestHandler):
     def handle(self):
         while True:
             self.data = self.request.recv(1024).decode('UTF-8', 'ignore').strip()
             if not self.data : break
             print(self.data)
             self.feedback_data =("回复\""+self.data+"\":\n\t你好，我是Server端").encode("utf8")
             self.request.sendall(self.feedback_data)

 host = '127.0.0.1'
 port = 9090
 server = socketserver.ThreadingTCPServer((host,port),myTCPhandler)
 server.serve_forever()

 客户端1-n

 import socket,time

 host = '127.0.0.1'
 port = 9090

 sk=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
 sk.connect((host,port))

 for i in range(10):
     sk.sendall(("你好，我是Client No.%d" %i).encode("utf8"))
     data = sk.recv(1024)
     print(data.decode('UTF-8', 'ignore'))
     time.sleep(2)
     i = i + 1
 sk.close()
