Question

我在after_sign_in_path_for覆盖ApplicationController。

这是方法，使用Domainatrix解析URL：

  def after_sign_in_path_for(resource)
      "#{resource.subdomain}." + host(request.url) + ":3000/profile" 
  end

  def subdomain(url)
    Domainatrix.parse(url).subdomain
  end

  def host(url)
    Domainatrix.parse(url).host
  end

当我的日志为：

时，我点击“提交”

它显示它正在重定向到正确的URL，但实际上没有发生任何事情。

如果我再次点击“提交”，则不会发生任何事情并生成以下日志（请注意第2行至最后一行）：

Started POST "/users/sign_in" for 127.0.0.1 at 2014-02-26 17:10:08 -0700
Processing by Devise::SessionsController#create as HTML
  Parameters: {"utf8"=>"✓", "authenticity_token"=>"0aZ8da/kt+uxPDvzQj4ypyVDgTBW7FzRNR7uHN6Hryo=", "user"=>{"email"=>"EMAIL", "password"=>"[FILTERED]", "remember_me"=>"0"}, "commit"=>"Sign in"}
  User Load (0.2ms)  SELECT "users".* FROM "users" WHERE "users"."id" = 16 ORDER BY "users"."id" ASC LIMIT 1
Redirected to trevor.lvh.me:3000/profile
Filter chain halted as :require_no_authentication rendered or redirected
Completed 302 Found in 2ms (ActiveRecord: 0.2ms)

当我将after_sign_in_path_for更改为：

时，为了进一步增加神秘感

def after_sign_in_path_for(resource)
  if resource.subdomain == subdomain(request.url)
  "#{root_url}profile"
  end
end

它正确地重定向到trevor.lvh.me:3000/profile。

知道这个Filter chain halted as :require_no_authentication rendered or redirected错误是什么？

替换

def after_sign_in_path_for(resource)
      "#{resource.subdomain}." + host(request.url) + ":3000/profile" 
  end

使用

def after_sign_in_path_for(resource)
      "http://#{resource.subdomain}." + host(request.url) + ":3000/profile" 
 end

http://协议遗失。

覆盖设计after_sign_in_path_for会出错：过滤链停止为：require_no_authentication呈现或重定向
