Django Rest Framework AttributeError：'響應'對象沒有'編碼'屬性

Question

我想通過使用APIClient類而不是APIRequestFactory對我新創建的視圖集進行簡單測試，但視圖失敗，並顯示以下錯誤：

AttributeError: 'Response' object has no attribute 'encoding' 

如果我使用API​​RequestFactory雖然，但我因爲我使用TokenAuthentication需要APIClient它工作正常。

這是上下文中，我使用的客戶端：

api_client = APIClient() 
reversed_url = reverse('showcase:ajax:publisher-dashboard', kwargs={'pk': 1}) 
client_token = cm.Client.objects.get(first_name='Cliente 1', 
            last_name='Prueba Showcase').user.auth_token.key 
api_client.credentials(HTTP_AUTHORIZATION='Token ' + client_token) 

request = api_client.get(reversed_url, format='json') 
response = views.PubViewSet.as_view({'get': 'dashboard'})(request, pk=1) 

的結果是不提供證書和settings.py中禁用TokenAuth相同。

使用時和APIClient：

這些使用API​​RequestFactory當是響應對象的內容

Answer 1

我覺得你在這行代碼有錯誤：

request = api_client.get(reversed_url, format='json') 
response = views.PubViewSet.as_view({'get': 'dashboard'})(request, pk=1) 

api_client.get已經返回HTTPResponse，所以你不需要傳遞我t以VewSet作爲請求。相反，它試試這個：

response = api_client.get(reversed_url) 
assert response.status_code == 200
