How can I use Storage::disk('s3')->put() when my s3's x-amz-server-side-encryption is AES256 at Laravel 5.1?

RT.

This is my s3's filesystem configure:

's3' => [
        'driver' => 's3',
        'key'    => env('AWS_ACCESS_KEY_ID'),
        'secret' => env('AWS_SECRET_ACCESS_KEY'),
        'region' => env('AWS_REGION'),
        'bucket' => env('AWS_BUCKET'),
    ],

And this is my composer.json:

"require": {
        "laravel/framework": "5.1.*",
        "barryvdh/laravel-ide-helper": "~2.0",
        "predis/predis": "~1.0",
        "guzzlehttp/guzzle": "~5.0",
        "league/flysystem-aws-s3-v3": "~1.0",
        "raven/raven": "0.12.*"
    },

And this is my s3's bucket policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "DenyUnEncryptedObjectUploads",
            "Effect": "Deny",
            "Principal": {
                "AWS": "*"
            },
            "Action": "s3:PutObject",
            "Resource": "arn:aws:s3:::*****bucket_name*****/*",
            "Condition": {
                "StringNotEquals": {
                    "s3:x-amz-server-side-encryption": "AES256"
                }
            }
        }
    ]
}

Yes, I used "s3:x-amz-server-side-encryption": "AES256" as my PutObject's condition, but I wanna use like this code:

Storage::disk('s3')->put('test.log','123');

But when I run it, I will got response like this:

[Aws\S3\Exception\S3Exception]

So, how can I do this? Thanks!
