Hello All,

I am new to GOLang development

I am trying to setup GCP Emulator

First I started the server as stated in various examples

opts := fakestorage.Options{
		InitialObjects: []fakestorage.Object{
			{
				ObjectAttrs: fakestorage.ObjectAttrs{
					BucketName: TestBucket,
					Name:       "module/file1",
				},
			},
			{
				ObjectAttrs: fakestorage.ObjectAttrs{
					BucketName: TestBucket,
					Name:       "module/file2",
				},
			},
		},
		StorageRoot: "/test",
		Scheme:      "http",
		Host:        "localhost",
		Port:        9000,
	}
	server, err := fakestorage.NewServerWithOptions(opts)

I also set this

os.Setenv("STORAGE_EMULATOR_HOST", fmt.Sprintf("%s:%s", "http://localhost", "9000"))

I am assumed that by doing so, a new server would be hosted in localhost:9000 and point the StorageRoot folder path as the new storage folder.

And when I call this below method to list the objects found inside StorageRoot i.e /test/module. I do not get any objects.

client, err := storage.NewClient(cctx)

it := client.Bucket(message.Bucket).Objects(cctx, &storage.Query{
		Prefix: strings.Split(message.Name, "/")[0] + "/module/",
		// Delimiter: "_",
	})

Your insights would be helpful.

Hi, @fsouza

Could you take a look on this issue? I'm facing the same. After environment variable "STORAGE_EMULATOR_HOST" being set client can't find object in storage, as fakestorage server responds 404.

All of a sudden my case was completely fixed after switching from Host to PublicHost.
@sourabhsparkala I believe yours will be also
@fsouza maybe include an example with STORAGE_EMULATOR_HOST env var in documentation?
