Python套接字在使用pygame时只接收一次输入

import pygame
import threading
import socket

# 初始化pygame
pygame.init()

# 创建套接字
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind(('localhost', 8888))
sock.listen(1)

# 接收数据的函数
def receive_data():
    while True:
        conn, addr = sock.accept()
        data = conn.recv(1024)
        # 处理接收到的数据
        print("Received:", data.decode())
        conn.close()

# 创建接收数据的线程
receive_thread = threading.Thread(target=receive_data)
receive_thread.start()

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