设置家庭路线，以指导在Sinatra简单认证

我试图使用Sinatra简单认证来强制用户登录才能访问该网站。因此，主页将是登录，然后应该能够使用该网站而不会提示它。目前我无法找到一种方法来登录后重定向到主页面。设置：家庭正在工作，因为它应该。设置家庭路线，以指导在Sinatra简单认证

请从您的帖子删除多余的代码。我们不需要看到所有这些。另外，欢迎来到SO！ – thesecretmaster

感谢您的帮助，不幸的是，这造成了无限循环。为了说清楚，我不希望用户在没有登录的情况下能够做任何事情（甚至没有查看索引页） – Faisal

10但是用户必须先登录？他们必须访问登录路线。 – thesecretmaster

如果你想要做的是检查用户是否只是任何路线之前登录的“/”您可以使用此：

before do 
    if request.path != "/" 
     if # statement which returns false if a user is logged in 
      redirect "/" 
     end 
    end 
end
