推荐答案
这取决于您使用的服务器端语言.在PHP中，您可以执行以下操作，在其中引用 $ _ SERVER ['REQUEST_URI'] :
It depends on what server-side language you're using. In PHP you could do something like this, where I reference $_SERVER['REQUEST_URI']:
<?php $encodedUrl = htmlentities(urlencode($_SERVER['REQUEST_URI'])); ?>
<iframe src="http://www.facebook.com/plugins/like.php?href=<?php echo $encodedUrl; ?>&layout=standard&show_faces=true&width=450&action=like&colorscheme=light&height=80" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:450px; height:80px;" allowTransparency="true"></iframe>
如果您不使用服务器端语言，则可以使用JavaScript进行.这未经测试，但是:
If you're not using a server-side language, you could do it in JavaScript. This is untested, but:
<script type="text/javascript">
var encodedUrl = escape(encodeURIComponent(window.location));
document.write('<iframe src="http://www.facebook.com/plugins/like.php?href=' + encodedUrl + '&layout=standard&show_faces=true&width=450&action=like&colorscheme=light&height=80" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:450px; height:80px;" allowTransparency="true"></iframe>');
</script>
