Django 1.9.2测试客户端问题

我使用Django==1.9.2和djangorestframework==3.3.2和django.test.Client进行一些测试。问题是，当我执行我的测试，我流汗这个错误：Django 1.9.2测试客户端问题

ERROR: test_view (main.tests.test_http.TestMainViewSet)

KeyError: u'CSRF_COOKIE'

我的测试代码如下所示：

import json 

from django.test import Client 
from django.core.urlresolvers import reverse 
from django.contrib.auth.models import User 


class TestMainViewSet(TestCase): 

    def setUp(self): 
     self.client = Client(
      HTTP_HOST='example.com' # I have also tried removing this 
     ) 
     self.create_read_url = reverse('books-list') 
     User.objects.create_user(
      username="username", 
      email="[email protected]", 
      password="123" 
     ) 

    def test_create(self): 
     self.client.login(username='username', password="123") 
     # In this case I'm doing a POST, but it is the same with a GET 
     response = self.client.post(
      self.create_read_url, 
      data=json.dumps({'title': "Create"}), # I have also tried without the json.dumps 
      content_type='application/json' 
     ) 

     data = json.loads(response.content) 
     print data 

     self.assertEqual(response.status_code, 201) 
     self.assertEquals(data['title'], "Create")

我view代码：

from django.contrib.auth.mixins import LoginRequiredMixin 

from rest_framework import viewsets 

from .serialiazers import (
    BookSerializerRead, 
    BookSerializerWrite, 
) 

class MainViewSet(LoginRequiredMixin, viewsets.ModelViewSet): 
    queryset = Book.objects.all() 
    serializer_class_read = BookSerializerRead 
    serializer_class_write = BookSerializerWrite

上urls.py：

from rest_framework import routers 

router = routers.DefaultRouter() 
router.register(r'books', MainViewSet, 'books') 


urlpatterns = [ 
    url(r'^api/', include(router.urls)), 
]

根据关于它的Django doc，我不需要额外任何东西来避免CSRF checks, ，因为正如文中所说：“默认情况下，测试客户端将禁用您的站点执行的任何CSRF检查。”，并且我也知道即enforce_csrf_checks=False默认上的Client。

我已经找到了一个细节，但如果我创建一个客户端的实例self.client = Client(HTTP_HOST='example.com', CSRF_COOKIE='xxxxxx')然后它的工作，但是实际上需要？这不是文件所说的，所以我想我做错了什么。有人可以帮我吗？我将不胜感激任何帮助。在此先感谢

DRF提供不同的测试机制，你可能想尝试那些：HTTP：//www.django-rest-framework .org/api-guide/testing/ –

感谢您的建议@TomCarrick，非常有用，我之前没有使用它。我肯定会测试这个。我的主要问题是从“Django 1.8.4”变成了“Django 1.9.2”，这是否破坏了这个？从我的角度来看，它与'Django'本身有关，最后它是'json'到'Django Rest Framework'端点的请求，它应该已经工作了，我认为:(。再次感谢队友。 –

尝试使用DRF的APITestCase作为基类的测试用例：

from rest_framework.testing import APITestCase 

class TestMainViewSet(APITestCase): 
    ...
