I am providing you the Github sample for Java to upload Objects <https://github.com/googleapis/google-cloud-java/blob/master/google-cloud-examples/src/main/java/com/google/cloud/examples/storage/snippets/CreateBlob.java> to Cloud Storage bucket since you were able to go through the first step of creating an empty object, but just uploading the Object is what you are having issues with. As I can see from the code, you are trying to send requests to the Cloud Storage using the XML API and using application default credential <https://cloud.google.com/docs/authentication/production>to authenticate, I am providing you this documentation <https://cloud.google.com/storage/docs/xml-api/java-samples> on how to do that. As you are trying to create signed URLs to control access to buckets, I would recommend going through this article <https://cloud.google.com/storage/docs/access-control/create-signed-urls-program>which explains how to do it.
I understand that you want to figure out what could be missing in your code, I think StackOverflow Community will be able to provide a better guidance and a probable solution to your inquiries as Google Group is intended for Google Cloud general product discussion purposes only. I would recommend going to Stack Overflow using the proper Cloud Storage tag <https://stackoverflow.com/questions/tagged/google-cloud-storage> regarding this issue for further assistance. Also, if you think that our documentation does not provide enough guidance regarding what you are trying to achieve you can you can report it in Public Issue Tracker <https://developers.google.com/issue-tracker/>. Issue Tracker is a tool used at Google to track bugs and feature requests during product development, even documentations. So this way we would be able to provide more information in our documents according to your needs. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
