Django 500错误：WSGIRequest对象没有属性“作用域”

Question

当我使用uwsgi在服务器上部署应用程序时，出现错误

AttributeError at /
'WSGIRequest' object has no attribute 'scope'

在本地计算机上没有这样的问题，一切正常。

出现此错误的代码部分：

class UserActivityMiddleware(MiddlewareMixin):

    def process_response(self, request, response):
        activities = [activity for activity in ACTIVITIES if re.match(activity['path'], request.scope.get('path'))
                      and activity['method'] == request.scope['method']]
        if activities:
                 .....
