Question

我正在尝试使用Sinatra simple auth强制用户登录，然后才能访问该站点。所以主页将是登录，然后应该能够使用该网站而不被提示它。目前我无法找到一种在登录后重定向到主页面的方法。 set：home正在按预期工作。

如果您要做的是检查用户是否在除＆＃34; /＆＃34;之外的任何路线之前登录;你可以用这个：

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