python - 找不到 Facebook 后端

Question

伙计们，我似乎无法让它工作，在阅读了类似的问题后，我的问题不是因为没有指定 key 和 secret ，也不是因为我忘记在 facebook 之后添加“-oauth2”。 请帮忙??

我在浏览器上看到的只是未找到后端。也许只是因为我的 django 或 python 版本太新了？？ 我使用 python 3.6 和 django 2.0...

这是我项目的settings.py

SECRET_KEY = '<my_secret_key>'

                'social_django.context_processors.login_redirect',
            ],
        },
    },
]

# python social auth settings
SOCIAL_AUTH_FACEBOOK_KEY = '<facebook_app_id>'

SOCIAL_AUTH_FACEBOOK_SECRET = '<facebook_app_secret>'

SOCIAL_AUTH_FACEBOOK_SCOPE = ['email']

SOCIAL_AUTH_FACEBOOK_API_VERSION = '2.11'

AUTHENTICATION_BACKENDS = [
    'social_core.backends.facebook.FacebookAppOAuth2',
    'social_core.backends.facebook.FacebookOAuth2',
    'django.contrib.auth.backends.ModelBackend',
]

SOCIAL_AUTH_URL_NAMESPACE = 'social'

SOCIAL_AUTH_PIPELINE = (
    'social_core.pipeline.social_auth.social_details',
    'social_core.pipeline.social_auth.social_uid',
    'social_core.pipeline.social_auth.social_user',
    'social_core.pipeline.user.get_username',
    'social_core.pipeline.user.create_user',
    'social_core.pipeline.social_auth.associate_user',
    'social_core.pipeline.social_auth.load_extra_data',
    'social_core.pipeline.user.user_details',
    'social_core.pipeline.social_auth.associate_by_email',
)

更新...这是我的主要应用程序的 urls.py

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('', include('social_django.urls', namespace='social')),
    path('admin/', admin.site.urls),
    path('', include('main_app.urls') ),
    path('cuentas/', include('cuentas.urls')),
]

if settings.DEBUG is True:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

这是使用 facebook html 链接登录

<a href="{% url 'social:begin' 'facebook-oauth2' %}">Facebook</a>

我刚刚在 settings.py 中添加了配置以输出更多日志信息，所以这是我尝试使用 facebook 登录时的输出

omab绝对正确，为 facebook 后端插入 name 属性就成功了。

# Use 'facebook' instead of 'facebook-oauth2'
{% url 'social:begin' 'facebook' %}
