Question

我想在我的项目中创建自定义中间件。但我收到这样的错误：

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

我认为问题可能出在我的python版本上，我正在使用版本 3.7 。

这是我的文件夹结构：

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

middleware.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

settings.py

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

Answer 1

我认为您已经正确编辑了 settings.py 。因为中间件部分似乎正确。您可以确认是否正确编辑了settings.py，如下所示

settings.py

import os

BASE_DIR = ...

SECRET_KEY = ...

DEBUG = ...

ALLOWED_HOSTS = ...

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    'soet', # your apps
]


MIDDLEWARE = [
    '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',

    'soet.middleware.StackOverFlowMiddleware' # your_middleware
]

Answer 2

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

查看位于https://github.com/vitorfs/soet/blob/master/soet/middleware.py的代码库并且您可以将其更改为python3语法（基本上只查看print语句）。

在以下位置访问django文档以创建中间件：https://docs.djangoproject.com/en/2.2/topics/http/middleware/

我想用django-soet创建一个自定义中间件
