如何使用Django-oauth-toolkit进行身份验证,使用Django-rest-framework测试API端点

Question

我有一个Django-rest-framework视图集/路由器来定义API端点.视图集定义如下:

class DocumentViewSet(viewsets.ModelViewSet):
    permission_classes = [permissions.IsAuthenticated, TokenHasReadWriteScope]
    model = Document

并且路由器被定义为

router = DefaultRouter()
router.register(r'documents', viewsets.DocumentViewSet)

与网址模式 url(r'^api/', include(router.urls))

我可以通过获取正确的访问令牌并将其用于授权,在浏览器/通过curl中点击此端点.但是,目前尚不清楚如何针对此端点编写测试.

这是我尝试过的:

class DocumentAPITests(APITestCase):
    def test_get_all_documents(self):
        user = User.objects.create_user('test', 'test@test.com', 'test')
        client = APIClient()
        client.credentials(username="test", password="test")
        response = client.get("/api/documents/")
        self.assertEqual(response.status_code, 200) 

这会因client.get()呼叫的HTTP 401响应而失败.使用django-oauth-toolkit进行oauth2身份验证,在DRF中测试API端点的正确方法是什么？

在编写测试时,您应该从测试本身中提取您未测试的任何内容,通常将任何设置代码放在setUp测试方法中.对于使用OAuth进行API测试的情况,这通常包括测试用户,OAuth应用程序和活动访问令牌.

对于django-oauth-toolkit和其他Django应用程序,我总是建议查看测试,看看他们是如何做到的.这样可以避免进行不需要的API调用,尤其是对于像OAuth这样的多部分进程,并且只创建所需的少数模型对象.

def setUp(self):
    self.test_user = UserModel.objects.create_user("test_user", "test@user.com", "123456")

    self.application = Application(
        name="Test Application",
        redirect_uris="http://localhost",
        user=self.test_user,
        client_type=Application.CLIENT_CONFIDENTIAL,
        authorization_grant_type=Application.GRANT_AUTHORIZATION_CODE,
    )
    self.application.save()

def test_revoke_access_token(self):
    from datetime import datetime
    from django.utils import timezone

    tok = AccessToken.objects.create(
        user=self.test_user, token='1234567890',
        application=self.application, scope='read write',
        expires=timezone.now() + datetime.timedelta(days=1)
    )

从那里你只需要使用已生成的令牌进行身份验证.您可以通过注入Authorization标头来执行此操作,也可以使用force_authenticate Django REST Framework提供的方法.

我对 OAuth2 使用了相同的库，

这对我有用

from oauth2_provider.settings import oauth2_settings
from oauth2_provider.models import get_access_token_model, 
get_application_model
from django.contrib.auth import get_user_model
from django.utils import timezone
from rest_framework.test import APITestCase

Application = get_application_model()
AccessToken = get_access_token_model()
UserModel = get_user_model()

class Test_mytest(APITestCase):

    def setUp(self):

        oauth2_settings._SCOPES = ["read", "write", "scope1", "scope2", "resource1"]

        self.test_user = UserModel.objects.create_user("test_user", "test@example.com", "123456")

        self.application = Application.objects.create(
                                                name="Test Application",
                                                redirect_uris="http://localhost http://example.com http://example.org",
                                                user=self.test_user,
                                                client_type=Application.CLIENT_CONFIDENTIAL,
                                                authorization_grant_type=Application.GRANT_AUTHORIZATION_CODE,
                                            )

        self.access_token = AccessToken.objects.create(
                                                    user=self.test_user,
                                                    scope="read write",
                                                    expires=timezone.now() + timezone.timedelta(seconds=300),
                                                    token="secret-access-token-key",
                                                    application=self.application
                                                )
        # read or write as per your choice
        self.access_token.scope = "read"
        self.access_token.save()

        # correct token and correct scope
        self.auth =  "Bearer {0}".format(self.access_token.token)

    def test_success_response(self):

        url = reverse('my_url',)

        # Obtaining the POST response for the input data
        response = self.client.get(url, HTTP_AUTHORIZATION=self.auth)

        # checking wether the response is success
        self.assertEqual(response.status_code, status.HTTP_200_OK)

现在一切都会按预期进行。希望这可以帮助。谢谢
