How to make a link work only for one ip address?

Question

Laravel

There is a file sharing service, it has links to download files. How to make the link work only for one ip address?

Answer 1

if($_SERVER[REMOTE_ADDR] === '....') echo "<a href='/'>Hidden</a>";

Answer 2

Write down the IP when you first download, generating a link.
In this case, the file must be given not in the form of a direct path, but through a proxy script that will also check the ip and give the file.
Perhaps there is a point in unique links that live for some limited time.

Answer 3

I don’t know how everything is arranged there, but on the download page, paste this code, changing it to your parameters

@if($_SERVER[REMOTE_ADDR] === '192.168.1.1')
        <a href='{{route('page.download')}}'>Download</a>;
@endif

Answer 4

It is better to do this not in PHP, but in Nginx: nginx.org/ru/docs/http/ngx_http_secure_link_module.html
