Javascript FB.getLoginStatus不'；不能在Chrome甚至沙盒中工作禁用
我按照railscast在我的网站上添加了“使用Facebook登录”功能，登录没有问题。但当尝试注销时，即使我在facebook开发者应用程序设置中禁用了沙盒模式，FB.getLoginStatus似乎也从未被激活（如其他一些讨论中所建议的）： 单击“注销”时，我无法看到我的警报 我运行的Chrome和Firefox具有相同的行为。谁能帮我找出我遗漏了什么？非常感谢 让我更具体地描述一下我遇到的“行为”：Javascript FB.getLoginStatus不'；不能在Chrome甚至沙盒中工作禁用,javascript,ruby-on-rails,omniauth,Javascript,Ruby On Rails,Omniauth,我按照railscast在我的网站上添加了“使用Facebook登录”功能，登录没有问题。但当尝试注销时，即使我在facebook开发者应用程序设置中禁用了沙盒模式，FB.getLoginStatus似乎也从未被激活（如其他一些讨论中所建议的）： 单击“注销”时，我无法看到我的警报 我运行的Chrome和Firefox具有相同的行为。谁能帮我找出我遗漏了什么？非常感谢 让我更具体地描述一下我遇到的“行为”： 第一次从mysite.com登录Facebook时，Facebook登录窗口将弹出并询问
<%= link_to "sign out facebook", "#" , id: "sign_out" %>
有类似问题的人有何评论？请告知。非常感谢。请尝试将true作为第二个参数添加到getLoginStatus，如FB dev doc中所述：
FB.getLoginStatus(function(response) {
// this will be called when the roundtrip to Facebook has completed
}, true);

// do something with response
