Question

我有一个RequestHandler类，该类将被实例化并传递给所有客户端，客户端将通过handle_new_request方法向其发送请求。 RequestHandler也应该能够独立执行这些请求。下面的请求看起来很普通，但是在服务于该请求的应用程序中可能要花一些时间，因此我想异步执行这些请求。

from collections import deque
import time
class Request:
    """
    Naive implementation of a request class.
    """
    def __init__(self, req_name: str):
        self.req_name = req_name


class RequestsHandler:
    """
    Implementation for a naive requests handler class that accepts
    requests from clients and serves them via a ThreadPool.
    """
    def __init__(self, max_working_threads:int = 5):
        self.max_working_threads = max_working_threads
        self.request_queue = deque()
    def handle_new_request(self, new_req: Request):
        """
        Puts the new request made by a client into the request_queue.
        :param new_req: Request made.
        :return: None
        """
        self.request_queue.append(new_req)
    def serve_request(self):
        """
        Pops a new request from the request queue and serves it.
        :return: None
        """
        new_request: Request = self.request_queue.popleft()
        time.sleep(5)
        print('served request %s'%new_request.req_name)

类handle_new_request的

serve_request和RequestHandler方法应该异步工作，而对象应该即使队列为空，也可以存活。

如何接受请求并在不同的线程中执行它们？
