未经授权的错误视图django-rest-framework-social-oauth2

Question

成功社交登录后，我被重定向到

SOCIAL_AUTH_LOGIN_REDIRECT_URL = "/users/ldata/"

但是它给出了未经授权的错误

HTTP 401 Unauthorized
Allow: GET, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept
WWW-Authenticate: Bearer realm="api"

{
  "detail": "Authentication credentials were not provided."
}

我的settings.py

REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': (
    'oauth2_provider.contrib.rest_framework.OAuth2Authentication',
    'rest_framework_social_oauth2.authentication.SocialAuthentication',
),

'DEFAULT_PERMISSION_CLASSES': (
    'rest_framework.permissions.IsAuthenticated',
),
}


AUTHENTICATION_BACKENDS = (
# for Google authentication
'social_core.backends.open_id.OpenIdAuth',
'social_core.backends.google.GoogleOpenId',
'social_core.backends.google.GoogleOAuth2',

#linkedin
