Question

Is there any possibility to list all files on my Google Cloud Storage bucket with the GAE SDK? I know that the Python SDK supports such a function, but I can’t find a similar function in the Java SDK.

If not available, will this be added in the future releases of the Java SDK?

Answer 1

You can use the Cloud Storage JSON API via its client library. Once you set up your credentials you can make the call like this:

Storage storage = new Storage(httpTransport, jsonFactory, credential);
ObjectsList list = storage.objects().list("bucket-name").execute();
for (Object obj : list.getItems()) {
  //...
}

You may want to use an AppIdentityCredential in this case as well, which will allow the bucket to be owned by your application, and not by a user.
