Django休息框架认证测试

Question

我正在尝试使用JWT进行身份验证的测试用例,在这种情况下使用django-rest-framework-jwt,然后,curl我得到了下一个,所以:

curl -X POST -d "email=testuser@test.com&password=testing" http://localhost:8000/api/auth/token/

得到:

{"token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjo0LCJlbWFpbCI6InRlc3R1c2VyQHRlc3QuY29tIiwiZXhwIjoxNDIyNTkxMTQ5LCJ1c2VybmFtZSI6InRlc3R1c2VyQHRlc3QuY29tIn0.OT8ggcZYWxcbSy0Vv8u5PA3QISIdarNXTVuvu4QQjnw"}

但是,当我运行我的测试用例时:

class BaseTestCase(TestCase):

    def setUp(self):
        self.csrf_client = APIClient(enforce_csrf_checks=True)
        self.email = 'testuser@test.com'
        self.name = 'test user'
        self.password = 'testing'
        user = Usuario.objects.create_user(email=self.email, name=self.name, password=self.password)
        user.save()
        self.data = {
            'email': self.email,
            'password': self.password
        }
        self.url = '/api/auth/token/'


class ObtainJSONWebTokenTests(BaseTestCase):

    def test_jwt_login_json(self):
        """
        Ensure JWT login view using JSON POST works.
        """
        client = APIClient(enforce_csrf_checks=True)

        response = client.post(self.url, self.data, format='json')
        self.assertEqual(response.status_code, status.HTTP_200_OK, response.data)

    def test_jwt_login_json_incomplete_creds(self):
        """
        Ensure JWT login view using JSON POST fails
        if incomplete credentials are used.
        """
        client = APIClient(enforce_csrf_checks=True)

        self.data = {
            'email': self.email
        }
        response = client.post(self.url, self.data, format='json')
        self.assertEqual(response.status_code, status.HTTP_400_BAD_REQUEST, response.data)

我懂了:

Creating test database for alias 'default'...

任何的想法？

有同样的问题.显然,当您使用默认序列化程序和路径localhost:8000/users /创建用户时,不会保存密码.通过运行curl请求然后查询数据库来确认.

按照本网站的说明:http://www.django-rest-framework.org/api-guide/serializers/#hyperlinkedmodelserializer这里是我的新UserSerializer类:

class UserSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
    model = User
    fields = ('username', 'first_name', 'last_name', 'email', 'password')
    extra_kwargs = {'password': {'write_only': True}}

def create(self, validated_data):
    user = User(
        email=validated_data['email'],
        username=validated_data['username']
    )
    user.set_password(validated_data['password'])
    user.save()
    return user

此代码假定用户名和电子邮件都是必填字段.显然,这可以根据您自己的业务逻辑进行更改

希望这可以帮助,

我没有准备好测试这个的计算机，但我相信 Django 在测试时使用单独的数据库，该数据库分别在测试开始和结束时创建和销毁。您必须在测试中创建用户（如果尚未创建），然后尝试使用它登录。测试数据库不包含通过这些凭据进行身份验证的用户。
