首先,我是 django/python
的新手。
我正在尝试创建一个登录网站,允许用户注册一个帐户
并通过电子邮件
或直接登录
通过 验证
fb
或 google
(Oauth
)
当我点击发送到 email
的验证 url 时,我收到错误消息。
错误
:
ValueError at /activate/Mjk/4p1-dcc5f7ed2e7c847fe362/
You have multiple authentication backends configured and therefore must
provide the `backend` argument or set the `backend` attribute on the user.

我的网站/设置
AUTHENTICATION_BACKENDS = (
'social_core.backends.facebook.FacebookOAuth2',
'social_core.backends.google.GoogleOAuth2',
'django.contrib.auth.backends.ModelBackend',
)
这是我收到错误时调用的函数
def activate(request, uidb64, token):
try:
uid = force_text(urlsafe_base64_decode(uidb64))
user = User.objects.get(pk=uid)
except (TypeError, ValueError, OverflowError, User.DoesNotExist):
user = None
if user is not None and account_activation_token.check_token(user,
token):
user.is_active = True
user.profile.email_confirmed = True
user.save()
login(request, user)
return redirect('home')
else:
return render(request, 'account_activation_invalid.html')
在通过fb
、google
添加oath
登录后,我开始收到错误
。
如果我从 AUTHENTICATION_BACKENDS
中删除“social_core.backends.facebook.FacebookOAuth2
”、“social_core.backends.google.GoogleOAuth2
” 电子邮件确认
将再次工作。
我在网上搜索过,我发现的唯一解决方案如下,但它没有解决我的问题。
最佳答案
我找到了解决方案。使用 login(request, user, backend='django.contrib.auth.backends.ModelBackend')
login()
完整代码如下:
def activate(request, uidb64, token, backend='django.contrib.auth.backends.ModelBackend'):
try:
uid = force_text(urlsafe_base64_decode(uidb64))
user = User.objects.get(pk=uid)
except (TypeError, ValueError, OverflowError, User.DoesNotExist):
user = None
if user is not None and account_activation_token.check_token(user, token):
user.is_active = True
user.profile.email_confirmed = True
user.save()
login(request, user, backend='django.contrib.auth.backends.ModelBackend')
return redirect('home')
else:
return render(request, 'account_activation_invalid.html')
关于python - 配置了多个身份验证后端,因此必须提供 `backend` 参数或为用户设置 `backend` 属性,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/45961459/
