我正在尝试使用 Facebook 将表单数据发布到我的应用程序。我的表单与对话框集成，我正在使用 form.submit() 提交表单。请看我的代码。post 数据不会出现在后端（例如 load-cargo-radio、city-id、train-id），但 fb_sig* 数据会出现。有谁知道关于使用 Facebook 发布表单数据是否有任何警告？谢谢！
注意：我已经尝试使用我的服务器域和我的 fb 回调 url 进行表单操作。两者都不起作用。
<div id="action_prompt">
Loading cargo...
</div>
<fb:js_string var="fbjs_load_cargo_select">
<div id="load_cargo_select">
<form id="load_cargo_select_form" action="http://railsacrosseurope.com/turn/load_cargo_select" method="POST">
<p>Your train has stopped in the city of Arhus.</p>
<p>Arhus produces the following goods:</p>
<ul>
<li>Dairy</li>
</ul>
<p>Your train is hauling the following goods:</p>
<ul>
<li>Timber</li>
</ul>
<p>What would you like to do?</p>
<input type="radio" id="load_cargo_radio" value="1">Load new goods</input>
<input type="radio" id="load_cargo_radio" value="2">Discard existing goods</input>
