python多线程—终止子线程

总体思路

1、获取需要终止的子线程id

2、根据子线程id，终止子线程。

过程

• 获取子线程id：

import threading
Thread_id = threading.get_ident()  # 获取子线程的id值

• 线程终止函数

def async_raise(Thread_id, exctype):"""raises the exception, performs cleanup if needed"""tid = ctypes.c_long(Thread_id)if not inspect.isclass(exctype):exctype = type(exctype)res = ctypes.pythonapi.PyThreadState_SetAsyncExc(tid, ctypes.py_object(exctype))if res == 0:raise ValueError("invalid thread id")elif res != 1:# """if it returns a number greater than one, you're in trouble,# and you should call it again with exc=NULL to revert the effect"""ctypes.pythonapi.PyThreadState_SetAsyncExc(tid, None)raise SystemError("PyThreadState_SetAsyncExc failed")

• 调用终止函数

def stop_thread_func():async_raise(tid, SystemExit)
