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)
