【问题描述】:
我一直在使用 Django 的身份验证模块,但最近不得不关闭它。 auth 模块通过重定向到登录页面并将您退出的页面设置为?next=/currentPage 参数来处理会话到期。
因此,如果我的会话在 #dashboard 过期,我将被重定向到:
mydomain/account/login?next=/#dashboard
在离开 Django auth 模块后,我注意到这已更改为:
mydomain/account/login/#dashboard
这似乎与我在阅读 URL Fragment and 302 redirects 后理解它应该起作用的方式一致,但是,我想操纵这个片段,但在我的 HttpResponse 对象中的任何地方都看不到它。
django.contrib.auth 使用以下函数来处理此请求,但我看不到它们将片段移动到哪里。实际上,我只想完全删除该片段,但如果不能,我会满足于将其放回 ?next= 参数中。
