Show assets in CP from private S3 Bucket with Temporary URLs

[nicorttngr]

Hi all,
i'm using temporary Urls for displaying images from our private S3 Bucket, which are transformed into a StreamDownload.

$path = 'asset.jpg';
$url = Storage::disk('s3)->temporaryUrl(
    $path, now()->addSeconds(30)
);

return response()->streamDownload(function () use ($url) {
    echo file_get_contents($url);
}, 'asset.jpg');

However in the control panel, the images when clicked on are still broken and return 404. The smallt humbs are shown, though.
Can I hook in the CP Asset Display and change the URL to also use the temporaryUrl? Or is there any other solution?

ya I made an addon to do this, but haven't released it yet: https://github.com/edalzell/private-eye

Thanks! I imported it and the frontend works, but the images in the cp are still broken.. 404 if AWS_URL is "/" or 403 if AWS_URL is the bucket with endpoint URL.
And regarding the Tag: What's the difference between the result of download and show?

[edalzell]

download is to download a private asset, like a PDF or something.

show creates a publicly accessible url you can use to access.

Ah okay, that's really helpful for what I've trying to do, thank you!
So I guess I have to wait for correct images in CP until your addon is released? But isn't this a common problem, when the bucket is private?

Nevermind, the problem comes with my S3 Hoster. I switched to AWS and the images in cp are working fine using your plugin. Thank you very much!
