Question

我刚开始学习Django，并尝试向我的应用程序添加中间件。

在ProjectFolder / app下，我具有以下文件：

一个空的__init__.py文件
settings.py文件-该文件的内容是默认内容，除了：

  MIDDLEWARE = (
     'SimpleMiddleware',
     'django.middleware.security.SecurityMiddleware',
     'django.contrib.sessions.middleware.SessionMiddleware',
     'django.middleware.common.CommonMiddleware',
     'django.middleware.csrf.CsrfViewMiddleware',
     'django.contrib.auth.middleware.AuthenticationMiddleware',
     'django.contrib.messages.middleware.MessageMiddleware',
     'django.middleware.clickjacking.XFrameOptionsMiddleware',
 )

SimpleMiddleware.py文件：

class SimpleMiddleware(MiddlewareMixin):

    def __init__(self, get_response):
        print("***********************************SIMPLE MIDDLEWARE")
        self.get_response = get_response
        # One-time configuration and initialization.

    def __call__(self, request):
        # Code to be executed for each request before
        # the view (and later middleware) are called.
        print("***********************************SIMPLE MIDDLEWARE")
        response = self.get_response(request)
        # Code to be executed for each request/response after
        # the view is called.
        return response

    def process_request(self, request):
        print("***********************************SIMPLE MIDDLEWARE")
        return None

url.py文件：

    from app import views

    urlpatterns = [
        path('hello', views.index, name='index'),
        path('core', include('core.urls')),
    ]

但是，当我通过命令“ python manage.py runserver”运行应用程序时，出现错误：

ImportError：SimpleMiddleware看起来不像模块路径

您知道我在做什么错吗？

您需要中间件的完整路径，并假设您给出的结构很可能是app.SimpleMiddleware.SimpleMiddleware

MIDDLEWARE = (
     'app.SimpleMiddleware.SimpleMiddleware',
     'django.middleware.security.SecurityMiddleware',
     'django.contrib.sessions.middleware.SessionMiddleware',
     'django.middleware.common.CommonMiddleware',
     'django.middleware.csrf.CsrfViewMiddleware',
     'django.contrib.auth.middleware.AuthenticationMiddleware',
     'django.contrib.messages.middleware.MessageMiddleware',
     'django.middleware.clickjacking.XFrameOptionsMiddleware',
 )
