示例1: simpleUpload

func simpleUpload(t *testing.T, bs distribution.BlobIngester, blob []byte, expectedDigest digest.Digest) {
	ctx := context.Background()
	wr, err := bs.Create(ctx)
	if err != nil {
		t.Fatalf("unexpected error starting upload: %v", err)
	}

	nn, err := io.Copy(wr, bytes.NewReader(blob))
	if err != nil {
		t.Fatalf("error copying into blob writer: %v", err)
	}

	if nn != 0 {
		t.Fatalf("unexpected number of bytes copied: %v > 0", nn)
	}

	dgst, err := digest.FromReader(bytes.NewReader(blob))
	if err != nil {
		t.Fatalf("error getting digest: %v", err)
	}

	if dgst != expectedDigest {
		// sanity check on zero digest
		t.Fatalf("digest not as expected: %v != %v", dgst, expectedDigest)
	}

	desc, err := wr.Commit(ctx, distribution.Descriptor{Digest: dgst})
	if err != nil {
		t.Fatalf("unexpected error committing write: %v", err)
	}

	if desc.Digest != dgst {
		t.Fatalf("unexpected digest: %v != %v", desc.Digest, dgst)

示例3: addBlob

// addBlob simply consumes the reader and inserts into the blob service,
// returning a descriptor on success.
func addBlob(ctx context.Context, bs distribution.BlobIngester, desc distribution.Descriptor, rd io.Reader) (distribution.Descriptor, error) {
	wr, err := bs.Create(ctx)
	if err != nil {
		return distribution.Descriptor{}, err
	}
	defer wr.Cancel(ctx)

	if nn, err := io.Copy(wr, rd); err != nil {
		return distribution.Descriptor{}, err
	} else if nn != desc.Size {
		return distribution.Descriptor{}, fmt.Errorf("incorrect number of bytes copied: %v != %v", nn, desc.Size)
	}

	return wr.Commit(ctx, desc)
}
