蝗虫：request_success.fire不执行任何操作

Question

只需围绕蝗虫的API整理我的第一个包装。触发了API函数（如果提供了错误的参数，则会在控制台中引发异常）。使用正确的参数，它可以工作，但是Locust界面中没有反映任何统计信息，就像什么也没有发生。

import time
from business_logic_refactored import BusinessLogic
from locust import User, task, between, events
class PolyClinet(BusinessLogic):

_locust_environment = None

def __getattr__(self, name):
    #func = BusinessLogic.__getattr__(self, name)
    func = BusinessLogic.authorize
    def wrapper(*args, **kwargs):
        start_time = time.time()
        try:
            result = func(*args, **kwargs)
            events.request_success.fire(request_type="TEST", name=name, response_time=total_time, response_length=0)
            self._locust_environment.events.request_success.fire(request_type="TEST", name=name, response_time=total_time, response_length=0)
        except Fault as e:
            total_time = int((time.time() - start_time) * 1000)
            self._locust_environment.events.request_failure.fire(request_type="TEST", name=name, response_time=total_time, exception=e)
        else:
            total_time = int((time.time() - start_time) * 1000)
            events.request_success.fire(request_type="grpc", name=name, response_time=total_time, response_length=0)
            ###self._locust_environment.events.request_success.fire(request_type="TEST", name=name, response_time=total_time, response_length=0)
            # In this example, I've hardcoded response_length=0. If we would want the response length to be
            # reported correctly in the statistics, we would probably need to hook in at a lower level

    return wrapper

要记录事件，您应该在User类中执行self.environment.events.request_success.fire（...）

例如，请参见https://github.com/SvenskaSpel/locust-plugins/blob/2958d265857a8730af3b6cd9fd05f8839ec8f383/locust_plugins/users.py#L70。

我不确定当您直接致电events.request_success时会发生什么。也许应该抛出一个异常..也可能有更好的记录...
