Original GitHub issue: https://github.com/fsouza/fake-gcs-server/issues/198

GCS client forms the GET url with param generation=0 which is not implemented in the server.
So, if it's not implemented, the quick fix may be replacing all

if generationStr != ""

if generationStr != "" && generationStr != "0"

so that it uses Server.GetObject()

otherwise, get/download object will fail. We can easily reproduce this by running example code.

Just wonder if GetObjectWithGeneration() will be implemented soon or any other better fix?

Hi @kc-panw, thanks for reporting and sorry for the delayed response. There aren't any plans for implementing GetObjectWithGeneration() at the moment, unfortunately.

Regarding generation being 0, I just pushed a fix.

Hi @fsouza, I ran into the same issue again by running the python sample code. The problem is you only update the getObject function, but there are rewriteObject and downloadObject as well.

Is there a reason that you don't want to update those two functions? Thanks in advance.
