示例1: BlobDispatcher

// BlobDispatcher takes the request context and builds the appropriate handler
// for handling blob requests.
func BlobDispatcher(ctx *handlers.Context, r *http.Request) http.Handler {
	reference := ctxu.GetStringValue(ctx, "vars.digest")
	dgst, _ := digest.ParseDigest(reference)

	blobHandler := &blobHandler{
		Context: ctx,
		Digest:  dgst,
	}

	return gorillahandlers.MethodHandler{
		"DELETE": http.HandlerFunc(blobHandler.Delete),
	}

示例2: getUserName

// getUserName attempts to resolve a username from the context and request. If
// a username cannot be resolved, the empty string is returned.

	// Fallback to request user with basic auth
	if username == "" {
		var ok bool
		uname, _, ok := basicAuth(r)
