Question

I have created a bucket on Amazon S3 and I kept some images in this bucket inside a folder. All the images are private and I am using Zend_Service_Amazon_S3 class of Zend.

How can I access the private images?

Answer 1

You can do this task by making private url Like this

public function get_s3_signed_url($bucket, $resource, $AWS_S3_KEY, $AWS_s3_secret_key, $expire_seconds) {
     $expires = time()+$expire_seconds;
     // S3 Signed URL creation
     $string_to_sign = "GET\n\n\n{$expires}\n/".str_replace(".s3.amazonAWS.com","", $bucket)."/$resource";
     $signature = urlencode(base64_encode((hash_hmac("sha1", utf8_encode($string_to_sign), $AWS_s3_secret_key, TRUE))));

     $authentication_params = "AWSAccessKeyId=".$AWS_S3_KEY;
     $authentication_params.= "&Expires={$expires}";
     $authentication_params.= "&Signature={$signature}";
     return $link = "http://s3.amazonAWS.com/{$bucket}/{$resource}?{$authentication_params}";
}

now use this url to get access.
