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 {

t.Fatalf("digest not as expected: %v != %v", dgst, expectedDigest)

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

t.Fatalf("failed to create random file: %v", err)

t.Fatalf("unexpected error finishing layer upload: %v", err)
}
return 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
}

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)
