我在这台服务器上有 apache 和许多图像。例如：http://test.com/images/abc.jpg我想有可能这样做：如果用户像这样访问 url http://test.com/images/download/abc.jpgapache 必须添加 header Content-Disposition: attachment; filename="abc.jpg"。我该怎么做？

You want to use a combination of mod_rewrite (to fake the "download" directory) and mod_headers (to add the Content-Disposition header).
您想使用 mod_rewrite（伪造“下载”目录）和 mod_headers（添加 Content-Disposition 标头）的组合。
Create a .htaccess file in the images directory:
在图像目录中创建一个 .htaccess 文件：
<filesmatch ".*"> Header set Content-Disposition attachment env=REDIRECT_force_download </filesmatch>
This will set the appropriate header whenever the "REDIRECT_force_download" environment variable is set.
每当设置“REDIRECT_force_download”环境变量时，这将设置适当的标头。
Create a download directory and add this .htaccess file:
创建一个下载目录并添加这个 .htaccess 文件：
RewriteEngine On RewriteRule (.*) ../ [L,NC,QSA,E=force_download:1]
This will redirect any image requests to the parent (images) directory while adding the "REDIRECT_force_download" environment variable that will trigger the Header command from above.
这会将任何图像请求重定向到父（图像）目录，同时添加将从上面触发 Header 命令的“REDIRECT_force_download”环境变量。
