.htaccess批量数字ID跳转规则错在哪里？

Question

我想做一个批量301跳转，通过.htaccess

计划实现：domain.com/123/ 301重定向到 domain.com/123.html

自己写了一个不对，求高手帮看看错在哪里，如下。

RewriteEngine On
RewriteRule ^([0-9]+)/$ /([0-9]+).html$ [L,R=301]

谢谢了。

Answer 1

Change your second line to
RewriteRule ^([0-9]+)/$ /$1.html [L,R=301]

This works because the $1 refers to the matched section within the parenthesis of your regex.
