how to get an object's storage class ?

[jdkealy]

I see in the Java SDK you'd get an object's storage class using the following, how would I do it using amazonica?

http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/s3/model/StorageClass.html

[mcohen01]

maybe (:storage-class (s3/get-object-metadata "bucket" "key"))

[jdkealy]

that returns nil

[mcohen01]

    getStorageClass

    public String getStorageClass()

    Returns:
        The storage class of the object. Returns null if the object is in STANDARD storage. See StorageClass for possible values

[jdkealy]

The key I'm looking at though is in Glacier.

This is what get-object-metadata returns

{:content-disposition nil, :expiration-time-rule-id nil, :user-metadata nil, :instance-length 1855830, :version-id nil, :server-side-encryption nil, :server-side-encryption-aws-kms-key-id nil, :etag "49a370b2166390078800941d9ccb39c3", :last-modified #object[org.joda.time.DateTime 0x78b85044 "2017-12-11T16:40:39.000-05:00"], :cache-control nil, :http-expires-date nil, :content-length 1855830, :content-type "image/gif", :restore-expiration-time nil, :content-encoding nil, :expiration-time nil, :content-md5 nil, :ongoing-restore nil}

get-object returns this error indicating it is not the standard storage class

   The operation is not valid for the object's storage class (Service:
   Amazon S3; Status Code: 403; Error Code: InvalidObjectState; Request
   ID: 6C4A2F86F24BE092)

i'm guessing maybe the storage class comes in as a header that we're not parsing

[mcohen01]

dumping the headers shows it's in the response headers. not sure why it isn't being populated in the ObjectMetadata. you may want to try asking on the sdk project.
