How To Get Base64 String (via Storage, not getUrl)?

[SlyDave]

A similar question to #1269, but the resolution for that was to use file_get_contents against $media->getPath(). I unfortunately cannot do that as the S3 bucket is private. I need to get the file's content from Storage before encoding it, rather than downloading it via file_get_contents across the public internet.

I was unable to find a method exposed by media-lib that would allow me to download the file from the configured disk in its binary format that I can then run through base64_encode.

Additionally, #1269 suggests using pathinfo, but that also needs access to the file.

And was wondering how best to achieve this?

I assume I'm going to have to do something like, using MimeTypes to resolve the pathinfo issue:

$file = Storage::disk($media->disk)->get($media->file_name);
$ext = MimeTypes::getDefault()->getExtensions($media->mime_type)[0] ?? 'jpg'; // TODO: throw if mimetype not knowable
$base64 = 'data:application/' . $ext . ';base64,' . base64_encode($file);

This doesn't work tho because using $media->file_name to pass to Storage::get() is missing the media key identifier (or whatever the PathGenerator is spitting out, in the uuidv4 attribute), using $media->getPath() includes it, but also includes the disk's root, which is added against when calling Storage::get(), and lastly using $media->getFullPath() wont work because it gives you the full path including http etc.

Cam up with the following that's working:

    $stream = $media->stream();
    $file = stream_get_contents($stream);
    fclose($stream);

    $ext = MimeTypes::getDefault()->getExtensions($media->mime_type)[0] ?? null; // TODO: throw if extension not knowable
    $base64 = 'data:application/' . $ext . ';base64,' . base64_encode($file);
    unset($file);
