使用套接字recv的无限循环终止线程

import socket
import threading

# 创建套接字
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind(('localhost', 8000))
sock.listen(1)

# 标志变量，用于控制循环的终止
running = True

# 线程函数，用于接收数据
def receive_data():
    global running
    while running:
        try:
            data, addr = sock.recvfrom(1024)
            # 处理接收到的数据
            print(data)
        except socket.error as e:
            print("Error: ", e)
            break

# 创建并启动线程
thread = threading.Thread(target=receive_data)
thread.start()

# 程序主逻辑
try:
    while True:
        command = input("请输入命令：")
        if command == "exit":
            # 修改标志变量的值为False，终止线程的执行
            running = False
            break
        else:
            # 执行其他操作
            pass
except KeyboardInterrupt:
    # 修改标志变量的值为False，终止线程的执行
    running = False

# 等待线程结束
thread.join()

# 关闭套接字
sock.close()
