在Python3.6.8中，需要将main函数中定义的子函数`build_req`和`build_rep`，调整到调用的语句之前。 手动停止的办法[参考](https://blog.csdn.net/qq_16583687/article/details/78163015) 1. 引入signal模块，构造退出函数 ```python import signal def quit(signum,frame): print('终止攻击') sys.exit(0) ``` 2. 在while循环前加入信号识别 ```python signal.signal(signal.SIGINT,quit) signal.signal(signal.SIGTERM,quit) while True: ...... ```
