“运行时错误：此事件循环已在运行”当同时收到多个请求时发生

如何解决“运行时错误：此事件循环已在运行”当同时收到多个请求时发生

我有一个宁静的烧瓶应用程序，我用 gunicorn 部署了这个应用程序。然后，我在某处阅读了有关异步编程的内容并想尝试一下。我加了一系列async/await和一个循环，但是好像有问题。当我使用 jmeter 发送几个同时请求时，RuntimeError: this event loop is already running. 发生了，而在这些异步更改之前，我的应用程序可以处理大量同时请求，但现在它甚至无法处理 5 个请求！我该如何解决这个问题？一般情况下，切换到异步可以让我的服务处理更多请求吗？

class Interpret(Resource):
    def get(self):
        user_id = request.args.get('user_id')
        query = request.args.get('query')
        client_id = request.args.get('client_id')

        # response,code = AGENT.handle_message(user_id,client_id,query)
        response,code = LOOP.run_until_complete(AGENT.handle_message(user_id,query))
        return [response],code

api.add_resource(Interpret,'/api/v1/interpret',endpoint='interpret')
