Function InjectJSONPropertiesFromBytes

base/util.go:1378–1392

InjectJSONPropertiesFromBytes takes the given JSON byte slice, and for each KV pair, inserts into b under the given key. This has the potential to create duplicate keys, which whilst adhering to the spec, are ambiguous with how they get read... usually "last key wins" - although there is no standar

(b []byte, kvPairs ...KVPairBytes)

// This has the potential to create duplicate keys, which whilst adhering to the spec, are ambiguous with how they get read...
// usually "last key wins" - although there is no standardized way of handling JSON with non-unique keys.
func InjectJSONPropertiesFromBytes(b []byte, kvPairs ...KVPairBytes) (new []byte, err error) {
	if len(kvPairs) == 0 {
		// noop
		return b, nil
	}

	b = bytes.TrimSpace(b)

	if !bIsJSONObject {

// isJSONObject checks if the given bytes are a JSON object,
// and also whether it's an empty object or not.
