python强制结束线程_在python中实现强制关闭线程的示例

如下所示：

import threading

import time

import inspect

import ctypes

def _async_raise(tid, exctype):

"""raises the exception, performs cleanup if needed"""

tid = ctypes.c_long(tid)

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")

def stop_thread(thread):

_async_raise(thread.ident, SystemExit)

class TestThread(threading.Thread):

def run(self):

print

"begin"

while True:

time.sleep(0.1)

print('end')

if __name__ == "__main__":

t = TestThread()

t.start()

time.sleep(1)

stop_thread(t)

print('stoped')
