Question

我已经在users/middleware.py文件中创建了自定义中间件。直到昨天，该请求在中间件返回HttpResponseRedirect之后终止。但是今天，请求继续进行并重新加载了个人资料页面。下面是我的middleware.py文件。我正在使用Django 2.1.7

from django.utils.deprecation import MiddlewareMixin
import pytz
from django.urls import reverse_lazy , reverse
from django.utils import timezone
from django.http import HttpResponse ,HttpResponseRedirect


class TimezoneMiddleware(MiddlewareMixin):
    def process_request(self, request):
        request.session['timezone'] = 'Asia/Kolkata'
        timezone.activate(pytz.timezone('Asia/Kolkata'))

class CheckProfileMiddleware(MiddlewareMixin):
    def process_request(self,request):
        if request.user.first_name == "" or request.user.last_name == "":

            if 'profile' not in request.path_info:
                request.session['is_incomplete']=1
                # return HttpResponse("ok")
                return HttpResponseRedirect(reverse('profile')) 
        else:
            request.session['is_incomplete']=0
            return None

基本上，如果用户的个人资料不完整，我想将其重定向到个人资料页面。以下是我在setings.py

中的中间件

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'users.middleware.TimezoneMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'users.middleware.CheckProfileMiddleware',
]

当我使用return HttpResponse时，它会停止执行，但会继续在HttpResponseRedirect上执行

这是我的URLConf。

path('profile/', profile, name='profile'),

我的view.py

@login_required
def profile(request):
    user= User.objects.get(id=request.user.id)
    user_profile = Profile.objects.get(user_id=request.user.id)
    if request.method == 'POST':
        u_form = UserUpdateForm(request.POST,instance=request.user)
        p_form = ProfileUpdateForm(request.POST, request.FILES, instance=request.user.profile)
        if u_form.is_valid() and p_form.is_valid():
            u_form.save()
            p_form.save()
            messages.success(request, f' Your Profile has been updated!')
            return redirect('profile')

    else:
        u_form = UserUpdateForm(instance=request.user)
        p_form = ProfileUpdateForm(instance=request.user.profile)
        context={
            'profile' : profile,
            'u_form': u_form,
            'p_form': p_form,
            'users':user,
        }
        return render(request,'profile.html', context)

实际上我找到了解决方案。罪魁祸首是AJAX请求。在每个页面上，AJAX与页面加载同时调用。因此，每当调用AJAX时，中间件就将其视为GET请求，并再次重定向到profile视图。所以我把条件放在中间件中以避免它是AJAX请求。我更新的middleware.py

class CheckProfileMiddleware(MiddlewareMixin):
    def process_request(self,request):

        if request.user.is_authenticated:
            if not request.path.startswith(settings.STATIC_URL):
                if request.user.first_name == "" or request.user.last_name == "":
                    if ('profile' not in request.path_info) and (not request.is_ajax()):
                        request.session['is_incomplete']=1
                        return HttpResponseRedirect(reverse('profile')) 
                else:
                    request.session['is_incomplete']=0

通过Django中间件重定向后，请求仍继续
