如何在 Python-auth/Django-Social 处理 AuthAlreadyAssociated？

Question

我使用此python-social-auth/social-app-django 将我的网络与社交媒体连接起来 想问一下同一个账号注册报错怎么处理？

例如，我使用 facebook 注册，然后再次使用 twitter 注册。两者都成功注册到两个单独的帐户，当我使用我的 Facebook 登录，然后在我的帐户设置页面上，我想连接我已经注册的 Twitter，然后它会显示错误消息

“AuthAlreadyAssociated at /oauth/complete/twitter/”

AuthAlreadyAssociated

当我在 twitter 重定向页面上授权后，当它被重定向回我的网站时，会出现此消息。

总之，已经注册在其他账户的账户怎么处理？

这是我的views.py：

@login_required
def settings(request):
    user = request.user
    try:
        github_login = user.social_auth.get(provider='github')
    except UserSocialAuth.DoesNotExist:
        github_login = None

    try:
        twitter_login = user.social_auth.get(provider='twitter')
    except UserSocialAuth.DoesNotExist:
        twitter_login = None

    try:
        facebook_login = user.social_auth.get(provider='facebook')
    except UserSocialAuth.DoesNotExist:
        facebook_login = None

    can_disconnect = (user.social_auth.count() > 1 or 
    user.has_usable_password())

    return render(request, 'profile/settings.html', {
        'github_login': github_login,
        'twitter_login': twitter_login,
        'facebook_login': facebook_login,
        'can_disconnect': can_disconnect
    })

这是我的 settings.html 模板：

{% load crispy_forms_tags %}

谢谢你，我希望有人可以为此提供解决方案，对不起我的英语不好。

您的问题已在此处得到解答： AuthAlreadyAssociated Exception in Django Social Auth

基本上答案是覆盖social_auth.middleware.SocialAuthExceptionMiddleware类中的默认方法process_exception()，并将这个中间件添加到你的settings.py中。
