使用 Devise after_sign_in_path_for 重定向循环 [英] Redirect loop with Devise after_sign_in_path_for

问题描述

我遇到了一些菜鸟问题.我想让设计重定向到用户访问的最后一页.所以我做了以下...

I'm having a bit of a noob issue. I wanted to get devise to redirect to the last page the user visited. So I did the following...

def after_sign_in_path_for(resource)
    request.referer
end

效果很好...除非用户实际上是通过导致重定向循环的原始表单登录.

Works great...except if the user is actually logging in through the original form which causes a redirect loop.

我试过了

def after_sign_in_path_for(resource)
   if (request.referer == "/users/sign_in")
  :pages_home
 else
  request.referer
 end

end

但这不起作用，很可能是因为我不知道 request.referer 在遇到原始用户登录页面 (www.example.com/users/sign_in) 时实际上返回了什么.

But thats not working, most likely because I have no idea what request.referer is actually returning when it encounters the original user login page (www.example.com/users/sign_in).

有什么想法吗?

tldr;使用devise，我想重定向到从(即/blog/4)登录的页面，除非页面是/users/sign_in

tldr; Using devise, I want to redirect to the page logged in from (i.e /blog/4) unless the page is /users/sign_in

已解决:

Matchu 是对的.request.referer 也在返回域...

Matchu was right. The request.referer was returning the domain as well...

http://example.com/users/sign_in

(注意:没有 www 前缀)

(note: no www prefix)

我仍然对 request.referer 的替代方法感兴趣，如果它不安全或效率低下.

I'm still interested in an alternative to request.referer if its an insecure or inefficient way.

推荐答案

不要重定向到推荐人 - 这通常是一个坏主意.

Don't redirect to referrers - it's generally a bad idea.

相反，在查询字符串或表单数据中传递一个 next 值.也许使用类似的东西:

Instead, pass a next value across in the query-string or form-data. Perhaps use something like:

def after_sign_in_path_for(resource)
  params[:next] || super
end

当用户尝试访问需要身份验证的页面(例如，/admin/posts/3/edit)时，身份验证 before_filter 会发出 redirect_to new_session_url(:next => request.path).然后编写登录操作和视图以保留 :next 查询字符串参数.

When a user tries to visit a page requiring authentication (e.g., /admin/posts/3/edit) the authentication before_filter issues a redirect_to new_session_url(:next => request.path). Then code up the login action and view to preserve the :next query-string parameter.
