How to create download link for an Amazon S3 bucket's object?

Question

I am learning Amazon S3 using S3 PHP Class. I have uploaded my all files to my S3 bucket, now I want to create links for each available file in my bucket.

Will the following function work for me?

public static function getAuthenticatedURL($bucket, $uri, $lifetime, $hostBucket = false, $https = false)
{

}

    $s3 = new S3('access-key', 'secret-key');
    $s3->getAuthenticatedURL($bucket, $uri, $lifetime, $hostBucket = false, $https = false);

Or another function like get_object_url, but get_object_url() not in my S3 class.

I am using Undesigned's Amazon S3 PHP class.

Answer 1

The following patterns are valid for constructing S3 URLs:

http(s)://<bucket>.s3.amazonaws.com/<object>
http(s)://s3.amazonaws.com/<bucket>/<object>

Answer 2

If you want the public to access the bucket, it is as simple as

http://[YourBucketName].s3.amazonaws.com/[YourFileName]

So long as you set permissions correctly.

If you're worried about download abuse, you'll want an authenticated URL (which I guess you want from your code sammple). In which case, I suggest you use the Amazon SDK: http://aws.amazon.com/sdkforphp/ as it contains examples of what you need.

$s3->getObjectUrl($bucket, $filename, '5 minutes');
