从WordPress Web中删除规范的URL错误

<link rel="canonical"
   href="http://www.brooklynsigns.com/retail-signs/stand-off-office-signs-new-york/"
   />

Google says to do it like this:

<link rel="canonical"
href="http://www.brooklynsigns.com/retail-signs/stand-off-office-signs-new-york"/>

What I want to do is that I URL in form like that "/> instead of /"/>.

Just change your Permalinks settings (/wp-admin/options-permalink.php) to use a Custom Structure and remove the last slash, putting the value /%postname%.
