facebook使用django app成功登录后重定向url

【中文标题】facebook使用django app成功登录后重定向url【英文标题】：redirecting url after facebook logs in successfully with django app 【发布时间】：2011-07-29 19:50:30 【问题描述】：我创建了一个带有用户登录/注册页面的 django 应用程序。我正在尝试与我的 django 登录一起实现 facebook 登录。为此，我关注了这个链接：enter link description here。正如文档所说，我创建了一个名为 FaebookConnectMiddleware.py 的文件并放入 settings.py 文件夹；并将数据库名称更改为我的数据库名称。现在 facebook 登录工作正常，但登录后，它被重定向到同一页面（django 注册页面，我放置 FB 登录按钮的位置）。我如何将它重定向到我的应用程序中的另一个页面。有人可以帮我解决这个问题。我将在此处粘贴 FacebookConnectMiddleware.py 代码。

【问题讨论】：
【参考方案1】：我认为你只需要将类顶部的变量声明为 false
class FacebookConnectMiddleware(object):
facebook_user_is_authenticated = False
【讨论】：
修复了错误，但是你能告诉我在使用 FB id 登录后如何重定向 url 吗？ 我不太了解 facebook 的东西，但我想你可以使用 Django 的重定向？ - ***.com/questions/523356/python-django-page-redirect以上是关于facebook使用django app成功登录后重定向url的主要内容，如果未能解决你的问题，请参考以下文章
