Add Metadata, headers (Expires, CacheControl) to a file uploaded to Amazon S3 using the Laravel 5.0 Storage facade

I am trying to find out how to add in Metadata or headers (Expires, CacheControl etc.) to a file uploaded using the Laravel 5.0 Storage facade. I have use the page here as reference.

http://laravel.com/docs/5.0/filesystem

The following code works correctly:

Storage::disk('s3')->put('/test.txt', 'test');

After digging I also found that there is a 'visibility' parameter which sets the ACL to 'public-read' so the following also works correctly.

Storage::disk('s3')->put('/test.txt', 'test', 'public');

But I would like to be able to set some other values to the header of the file. I have tried the following:

Storage::disk('s3')->put('/index4.txt', 'test', 'public', array('Expires'=>'Expires, Fri, 30 Oct 1998 14:19:41 GMT'));

Which doesn't work, I have also tried:

Storage::disk('s3')->put('/index4.txt', 'test', array('ACL'=>'public-read'));

But that creates an error where the 'visibility' parameter can not be converted from a string to an array. I have checked the source of AwsS3Adapter and it seems there is code for options but I can not seem to see how to pass them correctly. I think it takes the following:

protected static $metaOptions = [
    'CacheControl',
    'Expires',
    'StorageClass',
    'ServerSideEncryption',
    'Metadata',
    'ACL',
    'ContentType',
    'ContentDisposition',
    'ContentLanguage',
    'ContentEncoding',
];

Any help on how to accomplish this would be appreciated.

First, you need to call getDriver so you can send over an array of options. And then you need to send the options as an array.

So for your example:

Storage::disk('s3')->getDriver()->put('/index4.txt', 'test', [ 'visibility' => 'public', 'Expires' => 'Expires, Fri, 30 Oct 1998 14:19:41 GMT']);

Be aware that if you're setting Cache-Control it has to be passed as CacheControl. This may well be true for other keys with non-alphanumierc characters.
