Function SerializeMetadataHeader

pkg/handler/unrouted_handler.go:1617–1630

SerializeMetadataHeader serializes a map of strings into the Upload-Metadata header format used in the response for HEAD requests. e.g. Upload-Metadata: name bHVucmpzLnBuZw==,type aW1hZ2UvcG5n

(meta map[string]string)

// header format used in the response for HEAD requests.
// e.g. Upload-Metadata: name bHVucmpzLnBuZw==,type aW1hZ2UvcG5n
func SerializeMetadataHeader(meta map[string]string) string {
	header := ""
	for key, value := range meta {
		valueBase64 := base64.StdEncoding.EncodeToString([]byte(value))
		header += key + " " + valueBase64 + ","
	}

	// Remove trailing comma
	if len(header) > 0 {
		header = header[:len(header)-1]
	}

	return header
}

// Upload-Concat: partial
