发送对话框在iframe页面标签中不起作用。
在“发送对话框”页面https://developers.facebook.com/docs/reference/dialogs/send/
上执行了示例<html xmlns:fb="https://www.facebook.com/2008/fbml">
<body>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<div id="fb-root"></div>
<script>
// assume we are already logged in
FB.init({appId: '123050457758183', xfbml: true, cookie: true});
FB.ui({
method: 'send',
name: 'People Argue Just to Win',
link: 'http://www.nytimes.com/2011/06/15/arts/people-argue-just-to-win-scholars-assert.html',
});
</script>
</body>
</html>
但这会返回错误：
API Error Code: 3
API Error Description: Unknown method
Error Message: Unknown method
但是当更改为“Feed”对话框时，一切都运行正常。
