Python 我想用django soet创建一个自定义中间件

我想在我的项目中创建自定义中间件。但我遇到了这样的错误：

[  django.core.exceptions.ImproperlyConfigured: WSGI application 'custommiddle.wsgi.application' could not be loaded; Error importing module. ]

我想问题可能是我的python版本，我使用的是版本3.7

以下是我的文件夹结构：

custommiddle/  # project name
  __init__.py
  settings.py
  urls.py
  wsgi.py
  cmiddle/  # app name
    middle/  # directory
      __init__.py
      middleware.py
    __init__.py
    admin.py
    apps.py
    models.py
    tests.py
    views.py

中间件.py

from django.conf import settings

class StackOverflowMiddleware(object):
  def __init__(self, get_response):
      self.get_response = get_response

  def __call__(self, request):
      response = self.get_response(request)
      return response

  def process_exception(self, request, exception):
      if settings.DEBUG:
          print (exception.__class__.__name__)
          print (exception.message)
      return None

INSTALLED_APPS = [ 'soet' ]
MIDDLEWARE_CLASSES = [  'soet.middleware.StackOverFlowMiddleware' ]

    'django.contrib.staticfiles',

    'soet', # your apps
]

我假设您已正确编辑了设置.py。因为中间件部分似乎是正确的。您能否确认您正确编辑了settings.py，如下所示

设置.py

      self.get_response = get_response

  def __call__(self, request):
      response = self.get_response(request)
      return response

  def process_exception(self, request, exception):
      if settings.DEBUG:
          print (exception.__class__.__name__)
          print (exception.message)
      return None

soet正在使用python2语法。在Python 3中，print语句已替换为print（）函数

看看下面的代码库 您可以将其更改为python3语法（基本上只查看print语句）

访问django文档创建中间件，网址为：

访问django文档以创建中间件，网址为：

I在soet\middleware.py中解决了print语句。但是它会抛出同样的错误你能显示出你的错误的全部痕迹吗。也许您的应用程序中存在其他问题，只需卸载一次中间件即可检查。我在soet\middleware.py中解决了print语句。但是它会抛出同样的错误你能显示出你的错误的全部痕迹吗。您的应用程序中可能存在其他问题，只需卸载一次中间件即可进行检查。请在settings.py文件中正确配置所有内容。但它会抛出相同的错误，即在settings.py文件中正确配置的所有内容。但它抛出了同样的错误
