Question

我已经建立了facebook应用程序。它托管在： http://resihop.herokuapp.com/

该应用程序可以在这里看到： https://apps.facebook.com/393963983989013/

在Facebook上，它嵌入在iframe中。奇怪的是，对于某些用户来说，iframe的内容是空的，只是：对于某些用户，它会显示该页面。这是我从inspect元素得到的html：

工作：

<div>
    <noscript>&lt;div class="mas"&gt;&lt;div class="pam uiBoxRed"&gt;Du måste ha javascript aktiverat i din webbläsare för att använda Facebook-applikationer.&lt;/div&gt;&lt;/div&gt;</noscript>
        <form action="https://resihop.herokuapp.com/?fb_source=search&amp;ref=ts" method="post" target="iframe_canvas_fb_https" id="canvas_iframe_post_4fe8ad942b9be6531902412" onsubmit="return Event.__inlineSubmit(this,event)">

</div>

断裂：

<div>
    <noscript>&lt;div class="mas"&gt;&lt;div class="pam uiBoxRed"&gt;You need Javascript enabled in your browser to use Facebook Applications.&lt;/div&gt;&lt;/div&gt;</noscript>

我注意到的一个不同之处是行动是不同的。我现在已经等了好几个小时了，所以它可能是服务器不同步的东西，但可能不是。

我的Facebook应用程序为某些用户呈现空白
