PROSAGA码农传奇-Linux/Unix-Python套接字在使用pygame时只接收一次输入

<div class =“post-text”itemprop =“text”>
  
    它只能工作一次，因为您只创建一个到服务器的连接。 （在客户端代码的第6行。）您需要为每个请求创建一个新连接。
  
  
    客户代码：
  
   <pre>
 <code>
 import socket
import pygame
host = 'localhost' #loop back
port = 59769
pygame.init()
pygame.display.set_mode((250, 250))

def send(data):
    # Create a socket (SOCK_STREAM means a TCP socket)
    with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as sock:
        # Connect to server and send data
        sock.connect((host, port))
        sock.sendall(bytes(data + "\n", "utf-8"))

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()

if event.type == pygame.KEYDOWN and event.key == pygame.K_LEFT:
            send('2')
        if event.type == pygame.KEYDOWN and event.key == pygame.K_RIGHT:
            send('3')
        if event.type == pygame.KEYDOWN and event.key == pygame.K_UP:
            send('1')
        if event.type == pygame.KEYDOWN and event.key == pygame.K_DOWN:
            send('2')

pygame.display.update()

</code>
 </pre>
  
    服务器代码：
  
   <pre>
 <code>
 import socketserver

class MyTCPHandler(socketserver.BaseRequestHandler):
    """
    The request handler class for our server.

It is instantiated once per connection to the server, and must
    override the handle() method to implement communication to the
    client.
    """

def handle(self):
        # self.request is the TCP socket connected to the client
        self.data = self.request.recv(1024).strip()
        print(self.data.decode())

if __name__ == "__main__":
    HOST, PORT = "0.0.0.0", 59769

# Create the server, binding to localhost on port 9999
    with socketserver.TCPServer((HOST, PORT), MyTCPHandler) as server:
        # Activate the server; this will keep running until you
        # interrupt the program with Ctrl-C
        server.serve_forever()

</code>
 </pre>
