Apache2 mod_rewrite规则

Question

我如何将静态文件请求（如http://example.com/assets/img/logo.png）重写为http://assets.example.com/img/logo.png

主站点重写规则

    ServerName    example.com
    ServerAlias   example.com
    DocumentRoot /var/www/html/example.com/public/

   <Directory  /var/www/html/example.com/public/ >
      Options Indexes FollowSymLinks MultiViews
      AllowOverride All
      Order allow,deny
      allow from all
    </Directory>

RewriteEngine on
RewriteCond %{HTTP_HOST} !assets\.site\.com
RewriteCond %{REQUEST_URI} \.(png|gif|ico|css|js|tiff|woff|woff2|ogg|mp3)$ [NC]
RewriteRule ^(.*) http://assets.example.com$1 [NC,L]

资产子域正常运行

asset.example.com的虚拟主机配置

    ServerName     assets.example.com
    ServerAlias   assets.example.com
    DocumentRoot /var/www/html/example.com/public/assets/

   <Directory  /var/www/html/example.com/public/assets/ >
      Options Indexes FollowSymLinks MultiViews
      AllowOverride All
      Order allow,deny
      allow from all
    </Directory>

http://assets.example.com/img/logo.png给出了404，但如果我创建了/var/www/html/example.com/public/assets/assets/，则http://assets.example.com /img/logo.png回复200

根据您的评论，您只需要更改RewriteRule使用的正则表达式中捕获的内容即可。 现在$1是(.*) 。 您可以通过将其添加到捕获组之前的路径来从其中删除“资产”。

更改：

RewriteRule ^(.*) http://assets.example.com$1 [NC,L]

至：

RewriteRule ^assets/(.*) http://assets.example.com/$1 [NC,L]
