How can I get all the files on the server with cookies to access the download?

May I ask you the great God, how to make the file on the server must be in the URL containing cookies to download?
In particular, PHP redirects to a real file (php method I tried, but not enough to meet the needs of the need is even PHP access to carry cookies, and then redirected to the real file, also need to bring a cookie to download the real file)

Like this, for example:

After authentication via cookies, redirect to:

It is still necessary to bring cookies to download this file.
(The second URL does not seem to be PHP, because the real address of the downloaded file is this, no more jumps and redirects)
(URL is just an example, not accessible)

How does that happen?

Server is Nginx/linux

Server is Nginx/linux

The second one might be PHP,

The implementation is validated,

PHP verification, after the verification of PHP output file content, validation does not pass the output error message or output something.

Don't jump again. After verifying the cookie is valid, return the file directly

It is unlikely that application server rules will be implemented to control, generally PHP verification after jumping to the real address.

Using interceptors to verify the first

I used to have someone write an nginx extension with C.
It's now easy to implement with Lua.

Nginx can implement X-sendfile, the download directory is set to internal can be
