示例1: GetOrCreateSnapshotKey
// GetOrCreateSnapshotKey either creates a new snapshot key, or returns
// the existing one. Only the PublicKey is returned. The private part
// is held by the CryptoService.
func GetOrCreateSnapshotKey(gun string, store storage.MetaStore, crypto signed.CryptoService, createAlgorithm string) (data.PublicKey, error) {
_, rootJSON, err := store.GetCurrent(gun, data.CanonicalRootRole)
if err != nil {
// If the error indicates we couldn't find the root, create a new key
if _, ok := err.(storage.ErrNotFound); !ok {
logrus.Errorf("Error when retrieving root role for GUN %s: %v", gun, err)
return nil, err
}
return crypto.Create(data.CanonicalSnapshotRole, gun, createAlgorithm)
}
// If we have a current root, parse out the public key for the snapshot role, and return it
repoSignedRoot := new(data.SignedRoot)
