我想在我的django项目中创建一个auth模块.但是,当我打开我的网站url时,我有一个错误:'WSGIRequest'对象没有属性'user'
我试图找到有关此问题的信息,有人说问题出在MIDDLEWARE_CLASSES中,但我无法理解.
这是我的MIDDLEWARE_CLASSES:
MIDDLEWARE_CLASSES = (
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
#'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
)
MyProject的/ admin.py
from django.contrib import admin
from personal_area.models import UserProfile
admin.site.register(UserProfile)
MyProject的/ forms.py
from personal_area.models import UserProfile
from django.contrib.auth.models import User
from django import forms
class UserForm(forms.Model):
password = forms.CharField(widget=forms.PasswordInput())
class Meta:
model = User
fields = ('username', 'email', 'password')
class UserProfileForm(forms.ModelForm):
class Meta:
model = UserProfile
fields = ('website', 'picture')
MyProject的/ models.py
from django.db import models
from django.contrib.auth.models import User
class UserProfile(models.Model):
user = models.OneToOneField(User) …假设我有一个观点:
def pony_view(request, arg1, arg2):
... Make ponies, etc ...
和中间件:
class MyMiddleware(object):
def process_request(request):
# How do I access arg1, arg2 here?
当然arg1和arg2将通过URL params与urls.py传递.
我需要这样做的原因是因为我想在view函数运行之前向request.session添加一些东西(虽然我需要从URL中获取).
我可以在中间件中获取当前会话或cookie吗？
我试过但是我得到了:
'WSGIRequest' object has no attribute 'session'
我正在尝试在注册后立即重定向用户以转到协议条款页面。
这是我的中间件课程：
class TermsMiddleware(object):
def process_request(self, request):
if request.user.profile.filled_terms is None:
return redirect(reverse('terms'))
我收到以下错误，可以快速浏览一下我的服务器：
This webpage has a redirect loop
我有一个带有fill_terms字段的Profile模型类。
我有一个术语模板，当我手动访问它时，它工作得很好。
这也是我的网址匹配器：
url(r'^terms/', 'hana.views.terms', name='terms')
我如何摆脱这种重定向循环，并使用中间件将注册用户重定向到协议条款页面？
我想创建一个非常简单的中间件,只需在每个请求上打印"OK".问题是它会引发错误:
Traceback (most recent call last):

我用了django-allauth.
在我的 Django 应用程序中，白噪声通过以下方式起作用：
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'whitenoise.middleware.WhiteNoiseMiddleWare',
和
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
我正在将 django 应用程序部署到 heroku。我收到以下错误。白噪声安装成功。

ImportError: Module "whitenoise.middleware" does not define a "WhiteNoiseMiddleWare" attribute/class
下面是我的堆栈跟踪。我包含了完整的堆栈跟踪，以便可以了解完整的情况。事实上，我不确定现在发生了什么，而且相当令人沮丧。Heroku 整天都在和我战斗。

在我的中间件中，我想使用 Rest 框架中的 Response 对象。
我的中间件.py
from django.contrib.sessions.models import Session
from django.contrib.auth import logout
from django.contrib.auth.models import AnonymousUser
from rest_framework.response import Response
from rest_framework import status
class OneSessionPerUserMiddleware:

self.get_response = get_response

if request.user.session_key != Session.objects.filter(session_key__in = request.user.session_key):
logout(request)
return Response(request)
return self.get_response(request)
我想我通过了我的条件，但我收到了这个错误：
The response content must be rendered before it can be accessed
如何在中间件中正确使用 API Response 对象？ …
我编写了一个简单的 JWT 中间件来从 JWT 获取用户。该方法get_user_from_jwt返回一个 User 对象。
# app.middlewares.py
class JwtMiddleware:
def __init__(self, get_response):
self.get_response = get_response
def __call__(self, request):
self.process_request(request)
return self.get_response(request)
def process_request(self, request):
request.user = self.get_user_from_jwt(request.headers)
def get_user_pk_from_jwt(self, auth_header: str) -> int:
_, token = auth_header.split(' ')
decoded_payload = jwt.decode(token, settings.SECRET_KEY)
user_pk = decoded_payload.get('user_id', None)
return user_pk
def get_user_from_jwt(self, auth_header: str) -> User:
auth_header = headers.get('Authorization', None)
if auth_header:
try:
user_pk = self.get_user_pk_from_jwt(auth_header)
user = get_object_or_404(User, pk=user_pk)
return user
