利用浏览器缓存在 PHP 项目的 htaccess 中不起作用

Question

我在 php 项目的 .htaccess 文件中添加了以下代码。

<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType application/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 2 days"
</IfModule>

但 google 分析器仍未将其标记为已解决。它显示（未指定过期）每个图像，css 和 js。我需要做其他事情才能让它发挥作用吗？

你的配置看起来不错。

mod_expires 是否在您的 apache 配置中启用？

能否提供以下结果：

curl -I http://yourdomain/an_asset.jpg

只需使用此 php 代码 dirname(__FILE__)

将“/the/full/path/of/this/file”路径替换为正确的目录
