你可以试试这个代码:

RewriteBase /
RewriteRule ^tags/([^/]+)$ /tags/$1/ [L,R=301]

RewriteBase/ 告诉 apache 您的 URI 以 / 开头.如果您的站点位于子文件夹中，则应改为编写 RewriteBase/subfolder/.
^tags/([^/]+)$:搜索以 tags/ 开头的 URI，后跟 [^/]+ 表示除 / 之外的任何字符.它周围的 ( ) 用于捕获它并在重定向中使用它.因此，我们捕获 URI 中 tags/.../ 之间不是 / 的任何字符.(^ 标记字符串的开始，$ 标记字符串的结尾)
/tags/$1/ 是重定向.$1 表示第一个捕获的元素(那个巫婆在 ( ) 之间).
[L,R=301] 向 apache 指示它应该停止处理其他规则并使用 301 标头代码重定向.

RewriteBase / tells apache that your URI starts by a /. If your site was in a subfolder you should write RewriteBase /subfolder/ instead.
^tags/([^/]+)$: you search for an URI starting with tags/ followed by [^/]+ that means any characters except /. The ( ) around it are there to capture it and use it in the redirection. So we capture any characters that are not / between tags/.../ in the URI. (^ marks the start of the string while $ marks the end)
/tags/$1/ is the redirection. $1 means the first previous captured element (the one witch was between ( )).
[L,R=301] indicates to apache that it should stop process other rules and redirect with a 301 header code.
