导读：一、验证客户端链接的合法性 socket * secret_key=b ( msg=os.urandom(32 h= digest= respone= data_handler(conn,bufsize=1024 ( ( data= data: server_handler(ip_port,bufsize,backlog=5 tcp_socket_server= conn,addr= ( %(addr[0],addr[1 == ip_port=(

一、验证客户端链接的合法性

socket * secret_key=b ( msg=os.urandom(32 h= digest= respone= data_handler(conn,bufsize=1024 ( ( data= data: server_handler(ip_port,bufsize,backlog=5 tcp_socket_server= conn,addr= ( %(addr[0],addr[1 == ip_port=(,9999 bufsize=1024 server_handler(ip_port,bufsize)

= socket * secret_key=b msg=conn.recv(32 h= digest= client_handler(ip_port,bufsize=1024 tcp_socket_client= data=input(>: data: data == : tcp_socket_client.sendall(data.encode( respone= (respone.decode( == ip_port=(,9999 bufsize=1024 client_handler(ip_port,bufsize)

二、socketserver

= self.request.recv(1024(if name == "main":
HOST,PORT = "127.0.0.1",9999

<span style="color: #008000"&gt;#</span><span style="color: #008000"&gt; 设置allow_reuse_address允许服务器重用地址</span>
socketserver.TCPServer.allow_reuse_address =<span style="color: #000000"&gt; True
</span><span style="color: #008000"&gt;#</span><span style="color: #008000"&gt; 创建一个server,将服务地址绑定到127.0.0.1:9999</span>
server =<span style="color: #000000"&gt; socketserver.TCPServer((HOST,PORT),Myserver)
</span><span style="color: #008000"&gt;#</span><span style="color: #008000"&gt; 让server永远运行下去，除非强制停止程序</span>
server.serve_forever()</pre>

HOST,9999
data = "hello"

# 创建一个socket链接，SOCK_STREAM代表使用TCP协议
with socket.socket(socket.AF_INET,socket.SOCK_STREAM) as sock:
sock.connect((HOST,PORT)) # 链接到客户端
sock.sendall(bytes(data + "n","utf-8")) # 向服务端发送数据
received = str(sock.recv(1024),"utf-8")# 从服务端接收数据

print("Sent: {}".format(data))
print("Received: {}".format(received))
