您需要使用支持正则表达式的RedirectMatch:

You need to use RedirectMatch that supports regex:

RedirectMatch 301 ^/(abc\.php).*$ /$1

或者您也可以使用mod_rewrite.

通过httpd.conf启用mod_rewrite和.htaccess，然后将此代码放入您的DOCUMENT_ROOT/.htaccess文件:

Enable mod_rewrite and .htaccess through httpd.conf and then put this code in your DOCUMENT_ROOT/.htaccess file:

RewriteEngine On
RewriteRule ^(abc\.php).*$ /$1 [L,NC,R=301]
