How to get last modified date of a file in Google Cloud Storage?

Question

This guide on the Python library says cloudstorage.stat() returns

... last-modified time, header-length, content type for the specified file.

The Java guide however, seems to have no counterpart. At least, I cannot find it in GcsFileMetadata.

Is it possible to get this information using the Java library?

Answer 1

It seems the Java library doesn't have this feature (yet).

You can set this info manually, though:

GSFileOptionsBuilder optionsBuilder = new GSFileOptionsBuilder()
  .setBucket("my_bucket") 
  .setKey("my_object")
  .setAcl("public-read")
  .setMimeType("text/html") //etc etc
  .setUserMetadata("date-created", "01/09/2011", "owner", "Jon");

And retrieve this piece of metadata with

GcsFileMetadata.getOptions().getUserMetadata().get("date-created")
