在我的 vBulletin 板上使用 Facebook 的 Like 按钮时，我遇到了一个非常非常非常奇怪的问题。在我的线程模板中，我使用了以下代码，它位于 body 标记内：

<td class="vbs_forumdata alt1">
    <div id="fb-root"></div>
        <script type="text/javascript">(function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(d.getElementById(id))return;js=d.createElement(s);js.id=id;js.src="//connect.facebook.net/en_US/all.js#xfbml=1";fjs.parentNode.insertBefore(js,fjs)})(document,"script","facebook-jssdk");</script>
        <div id="thread_sharing_content_facebook">
            <div class="fb-like" data-href="{vb:raw sharingurl}" data-layout="button_count" data-send="false" data-show-faces="false" data-width="90"></div>
        </div>
    </div>
</td>

一旦模板被 vBulletin 引擎处理，变量 {vb:rawsharingurl} 就会被线程的规范 URL 替换，如下所示：

http://MYDOMAIN/threads/THREADID-THREADTITLE

例如：

http://www.mydomain.com/threads/1-Hello-Community

查看线程页面的 HTML 源代码，一切似乎都按预期工作：

<td class="vbs_forumdata alt1">
    <div id="fb-root"></div>
        <script type="text/javascript">(function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(d.getElementById(id))return;js=d.createElement(s);js.id=id;js.src="//connect.facebook.net/en_US/all.js#xfbml=1";fjs.parentNode.insertBefore(js,fjs)})(document,"script","facebook-jssdk");</script>
        <div id="thread_sharing_content_facebook">
            <div class="fb-like" data-href="http://www.mydomain.com/threads/1-Hello-Community" data-layout="button_count" data-send="false" data-show-faces="false" data-width="90"></div>
        </div>
    </div>
</td>

但是，如果我点击“Like”按钮来分享线程页面……戏剧性的来了：

线程页面的原始 URL 被搞砸了，变成了这样的东西：

http://MYDOMAIN/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/threads/THREADID-THREADTITLE

任何人都知道为什么我会遇到这个奇怪的问题？我唯一想自己弄清楚的是我的 htaccess 文件，其中包含一些重写规则。这几乎是 vBulletin 的默认设置……但是，无论如何，它们是：

RewriteEngine On
RewriteBase /

// Block Bad Bots
RewriteCond %{HTTP_USER_AGENT} [...]
RewriteRule ^.*$ - [F,L]

RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_HOST} !^www\..+$ [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]

RewriteRule ^forums/.* forumdisplay.php [QSA]
RewriteRule ^members/.* member.php [QSA]
RewriteRule ^threads/.* showthread.php [QSA]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]

RewriteRule ^(?:(.*?)(?:/|$))(.*|$)$ $1.php?r=$2 [QSA]

RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^(.*)$ - [NC,L]

RewriteRule ^(.*)$ - [R=404,L]

您可能需要添加 meta og 标签

 <meta type="og:url" content="<?php get_current_url(); ?>" >

试试看
