我知道有很多问题但很遗憾,其中任何一项都适合我。
我正在尝试阻止pdf直接访问,但让服务器在PDFJS中显示它。
这是我在尝试查看PDFJS中的pdf时可以得到的:文件丢失,403禁止,意外的服务器响应
我尝试过但没有用过:
RewriteEngine on rewriteRule
^path/to/folder? index.php [L]
这是执行所有验证的php文件的代码

无法粘贴整个html查看器代码,但它与其网站上的演示示例相同。为了显示文件,我用我的$文件更改了DEFAULT_URL。

最好的解决方案是将文件放在项目文件夹之外,类似于:
-joomla folder
--administrator
--components
--...
-pdf
通过这种方式,无法从网址访问您的pdf文件,但仍可从脚本访问:
$file = JPATH_ROOT."/../pdf/" . $page . ".pdf";
