当您在Facebook上发布YouTube链接时,播放器会显示在墙上,让其他人立即播放视频。这是怎么做到的,你如何为自己的网站做同样的事情,这样当人们发布你的某个网页的链接时,你可以在Facebook上显示一个小部件而不是实际的链接?

实际上,您需要向网站添加多个元标记
非常简单类似的东西:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:og="http://ogp.me/ns#"
xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<title>The Rock (1996)</title>
<meta property="og:title" content="The Rock"/>
<meta property="og:type" content="movie"/>
<meta property="og:url" content="http://www.imdb.com/title/tt0117500/"/>
<meta property="og:image" content="http://ia.media-imdb.com/rock.jpg"/>
<meta property="og:site_name" content="IMDb"/>
<meta property="fb:admins" content="USER_ID"/>
<meta property="og:description"
content="A group of U.S. Marines, under command of
a renegade general, take over Alcatraz and
threaten San Francisco Bay with biological
weapons."/>
...
</head>
...
</html>
如果你想嵌入视频,你可以这样做:
<html xmlns:og="http://ogp.me/ns#">
<head>
...
