我正在努力跟随this tutorial 也就是说，我可以让服务器发送类似文件的样式。css，如果请求的文件是样式。15458888.css，将重写规则放入htaccess文件中。

此规则

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.+).(d+).(js|css)$ $1.$3 [L]

所以我在head 标签：

<?php $time = filemtime(get_template_directory() .\'/assets/css/main.css\');?>
<link href="<?php echo get_template_directory_uri().\'/assets/css/main.\'.$time.\'.css\'?>" rel="stylesheet" type="text/css">

这个在Htaccess:

    # BEGIN WordPress
<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresByType image/jpg "access plus 6 hours"
    ExpiresByType image/jpeg "access plus 6 hours"
    ExpiresByType image/gif "access plus 6 hours"
    ExpiresByType image/png "access plus 6 hours"
    ExpiresByType text/css "access plus 6 hours"
    ExpiresByType application/pdf "access plus 1 week"
    ExpiresByType text/javascript "access plus 6 hours"
    ExpiresByType text/html "access plus 10 minutes"
    ExpiresByType image/x-icon "access plus 1 year"
    ExpiresDefault "access plus 3 hours"
</IfModule>
Header set X-Endurance-Cache-Level "2"
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteRule ^(.+).(d+).(js|css)$ $1.$3 [L]
</IfModule>

# END WordPress

正如您所看到的RewriteRule ^(.+).(d+).(js|css)$ $1.$3 [L] 已添加到</IfModule>

文件名已正确更改，如下所示：

<link href="http://ask.prosentra.com/wp-content/themes/tutorialblog/assets/css/main.1504604028.css" rel="stylesheet" type="text/css">

但服务器仍然没有实现我提到的规则。怎么了？

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.+)\\.(\\d+)\\.(js|css)$ $1.$3 [L]
