Question

在提供有效数据并提交表格后，我得到以下信息：Forbidden (CSRF cookie not set.): /membership/success/。我的模板中有一个{% csrf_token %}，并且我的settings.py中间件已配置为CSRF。

#urls.py

from django.contrib import admin
from django.urls import path, include
from membership import views as ms_views

membership_patterns = ([
    path("", ms_views.RegistrationPage.as_view(), name="register"),
    path("success/", ms_views.SuccessPage.as_view(), name="success")
], 'membership')

urlpatterns = [
    path('admin/', admin.site.urls),
    path('membership/', include(membership_patterns, namespace="new_members"))
]

# membership/views.py

from django.shortcuts import render
from django.template.loader import get_template
from django.views import View
from django.http import HttpResponse, HttpResponseRedirect
from membership.forms import RegisterForm
from django.urls import reverse
# Create your views here.

class RegistrationPage(View):
    def get(self, request):
        register_page = get_template('membership/signup.html')
        register_form = RegisterForm()
        return HttpResponse(register_page.render({'form' : register_form}))

    def post(self, request):

        submitted_form = RegisterForm(request.POST)
        if submitted_form.is_valid():
            return HttpResponseRedirect(reverse('membership:success'))
        return HttpResponse(reverse('membership:register'))


class SuccessPage(View):
    def get(self, request):
        return HttpResponse("Success")

# signup.html

{% extends 'index.html' %}

{% block content %}
    <form action="{% url 'membership:success' %}" method='post'>
        {% csrf_token %}
        {{ form.as_p }}
        <button type="submit">Submit</button>
    </form>
{% endblock %}

一旦表单提交并有效，我希望会出现302。就像我说的，尽管我被禁止了403。

由于成功页面没有逻辑，因此您可以选择免除CSRF令牌。导入以下模块

from django.views.decorators.csrf import csrf_exempt

并将@csrf_exempt放在函数开头

    @csrf_exempt
    def get(self, request):
        return HttpResponse("Success")

请参阅https://docs.djangoproject.com/en/2.2/ref/csrf/

但是，最好为您使用的每个模板包括{％csrf_token％}，以确保CSRF令牌的一致性传递
