python3中的多线程

Question

我在python3中使用多线程与Flask如下.想知道下面的代码是否有任何问题,如果这是使用线程的有效方法

import _thread
COUNT = 0

class Myfunction(Resource):

    @staticmethod
    def post():
        global GLOBAL_COUNT
        logger = logging.getLogger(__name__)

        request_json = request.get_json()

        logger.info(request_json)

        _thread.start_new_thread(Myfunction._handle_req, (COUNT, request_json))
        COUNT += 1

        return Response("Request Accepted", status=202, mimetype='application/json')

    @staticmethod
    def _handle_req(thread_id, request_json):
        with lock:


            empID = request_json.get("empId", "")

            myfunction2(thread_id,empID)

api.add_resource(Myfunction, '/Myfunction')

Answer 1

我认为较新的模块线程更适合python 3.它更强大.

import threading

threading.Thread(target=some_callable_function).start()

或者如果你想传递参数

threading.Thread(target=some_callable_function,
    args=(tuple, of, args),
    kwargs={'dict': 'of', 'keyword': 'args'},
).start()

除非您特别需要_thread以实现向后兼容性.与您的代码的效率无关,但无论如何都很好.
