-----------------------------------
Summary: GCS's presigned url requires blank Content-Type
Key: JCLOUDS-1400
URL: https://issues.apache.org/jira/browse/JCLOUDS-1400
Project: jclouds
Issue Type: Bug
Components: jclouds-blobstore
Affects Versions: 2.1.0
Reporter: Ivan Orlov
I am trying to signPutBlob for google cloud storage.
1)
{code:java}
BlobStoreContext context = ContextBuilder.newBuilder("google-cloud-storage")
.credentials(GOOGLE_ACCESS_KEY, GOOGLE_SECRET_KEY)
.buildView(BlobStoreContext.class);
BlobStore blobStore = context.getBlobStore();
Blob blob = blobStore
.blobBuilder("3.png")
.forSigning()
.contentLength(20493)
.contentType(MediaType.PNG) // setting contentType
.build();
HttpRequest httpRequest = context
.getSigner()
.signPutBlob("cs-29337eeb-27c1-4dbc-805c-f01ba1744eb1", blob, 3600);
{code}
2)
{code:java}
PUT
http://storage.googleapis.com/cs-29337eeb-27c1-4dbc-805c-f01ba1744eb1/3.png?Expires=1523454042&GoogleAccessId=access-s3%40storage-app-199609.iam.gserviceaccount.com&Signature=Aoam8qw0NYIDGDKBW4PpJXPklchTndaFwk4syrw0/K4c50hrDZFKG/oARWn1nSEKqRZlBuh2BBQtRSRNNH7Ol6Qhybo%2BX1hst7PxkaUue2iQwR%2B/t8p4izl%2BTGEJ99x2KdYsZb3Q7CmJvWkPlJ27KUGdVyJf/tTDGYwtE2uekXFxMu9r355N5RsBWBftW8kKnOaZBFsjO/q25bYs%2BAa/gQ01HfoQdDSPCYZ5QZST5G1vXYLuRcxYs3Hb33N3s5hq07/Nnopoai7CtrPKR1iSm766fzMaqZaSihXAQzCge5F25esML0kUkKvK%2BQBdFESD433Y1%2B33vg%2BZ9xvVlV3UlA%3D%3D
HTTP/1.1
Headers:
Content-Type: image/png{code}
Response:
{code:java}
<?xml version='1.0' encoding='UTF-8'?>
<Error>
<Code>SignatureDoesNotMatch</Code>
<Message>The request signature we calculated does not match the signature you
provided. Check your Google secret key and signing method.</Message>
<StringToSign>PUT

/cs-29337eeb-27c1-4dbc-805c-f01ba1744eb1/3.png</StringToSign>
</Error>
{code}
3) With no passed content-type it becomes text/plain
{code:java}
<?xml version='1.0' encoding='UTF-8'?>
<Error>
<Code>SignatureDoesNotMatch</Code>
<Message>The request signature we calculated does not match the signature you
provided. Check your Google secret key and signing method.</Message>
<StringToSign>PUT
text/plain
1523454042
/cs-29337eeb-27c1-4dbc-805c-f01ba1744eb1/3.png</StringToSign>
</Error>
{code}
4) And with passed _Content-Type: ""_ it's okay.
5) GoogleCloudStorageBlobRequestSigner.java
{code:java}
@Override
public HttpRequest signPutBlob(String container, Blob blob, long timeInSeconds)
{
return sign("PUT", container, blob.getMetadata().getName(),
GetOptions.NONE, timestamp.get() + timeInSeconds, null);
}
private HttpRequest sign(String method, String container, String name,
GetOptions options, long expires, String contentType) {
checkNotNull(container, "container");
checkNotNull(name, "name");
...
}
{code}
Why is the last parameter "contentType" always null? We could read it from the
blob, from
{code:java}
blob.getMetadata().getContentMetadata().getContentType();{code}
