Google Storage PHP client: Can't create object by POSTing to signed URL

We're using the Google\Cloud\Storage\StorageObject's signedUploadUrl method in the backend to generate upload URLs for our JS-based clients to be able to upload data into these URLs without need of authentication.

This URL is then retrieved by the clients, which in turn start a resumable upload by creating a storage object with a POST request in order to obtain an upload_id, and subsequent PUT requests would add data to it making use of this upload_id as authenticating factor.

Problem we're facing is that this signed upload URL is not behaving as expected: we're supposed to POST metadata (file name, content type) to it in order to obtain an upload_id, but this request fails with "SignatureDoesNotMatch".

As we're using the official PHP client library, we're clueless on what can be happening for this to be not working.

Did you try to send content-type header together with your subsequent PUT requests ? Since generated signed upload URL is being created together with content-type header, subsequent PUT requests must send the same header.

Have a look at here: google-cloud-php

options->contentType: If you provide this value, the client must provide this HTTP header set to the same value.
