Content-Type Metadata Incorrect

[swroberts]

When uploading files to s3, the content-type is not correctly read from the filename. As a result, each file is assigned "application/octet-stream", which affects the way files load in the browser, defaulting to downloading.

This thread on AWS Developer Forums (https://forums.aws.amazon.com/thread.jspa?threadID=86700) seems to suggest it can be solved with a slightly different method of passing arguments in the PUT command, but I don't know enough to test it out.

Thanks for all the hard work!

It is probably fixed in last version for Omeka v3, but can you check?

This still seems to be a problem.

Modifying put to explicitly supply the mime type using the ContentType parameter seems to work (at least for jpgs).

public function put($source, $storagePath): void
    {
        $bucket = $this->getBucketName();
        $mime = mime_content_type($source);
        $args = [
            'Bucket' => $bucket,
            'Key' => $storagePath,
            'SourceFile' => $source,
            'ACL' => 'public-read',
            'ContentType' => $mime,
        ];

I know very little about PHP coding, but I can put this in a merge request if it's helpful.
