/// tip | Dica

Pela especificação, você deve retornar um JSON com um `access_token` e um `token_type`, o mesmo que neste exemplo.

Isso é algo que você mesmo deve fazer em seu código e certifique-se de usar essas chaves JSON.

É quase a única coisa que você deve se lembrar de fazer corretamente, para estar em conformidade com as especificações.

            try {
                source = FileUtil.readUTF8(mappingFile);
            } catch (final Exception e) {
                logger.warn("{} is not found.", mappingFile, e);
            }
            try {
                final AcknowledgedResponse putMappingResponse = indicesClient.preparePutMapping(index).setSource(source, XContentType.JSON)

type ReplicaModifications struct {
	Status Status `xml:"Status" json:"Status"`
}

// SourceSelectionCriteria - specifies additional source selection criteria in ReplicationConfiguration.
type SourceSelectionCriteria struct {
	ReplicaModifications ReplicaModifications `xml:"ReplicaModifications" json:"ReplicaModifications"`
}

// IsValid - checks whether SourceSelectionCriteria is valid or not.

                                    if subtype == "json" or subtype.endswith("+json"):
                                        json_body = await request.json()
                            if json_body != Undefined:
