在Sinatra简单身份验证中将家乡路由设置为直达

Question

我正在尝试使用Sinatra简单身份验证来强制用户在能够访问站点之前登录。因此，主页将是登录，然后应该能够在不提示的情况下使用该站点。目前我无法找到登录后重定向到主页的方法。设置：家庭正在正常工作。

如果要检查用户是否在除"/"以外的任何路由之前登录，则可以使用以下命令：

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