在python中实现强制关闭线程的示例

 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')
