## Vista global

Primero, echemos un vistazo rápido a las partes que cambian desde los ejemplos en el **Tutorial - User Guide** principal para [OAuth2 con Password (y hashing), Bearer con tokens JWT](../../tutorial/security/oauth2-jwt.md){.internal-link target=_blank}. Ahora usando scopes de OAuth2:

## Requisitos

FastAPI está nos ombros de gigantes:

* <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> para as partes web.
* <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> para a parte de dados.

## Instalação

        request.encode(tempBuffer, 50);

        // When
        int bytesWritten = request.writeBytesWireFormat(buffer, offset);

        // Then
        // The writeBytesWireFormat writes the structure and calculates padding
        // Base structure: 24 bytes, then pad8 alignment, then token: 5 bytes
        // Total bytes written includes padding for 8-byte alignment
        int expectedBytesWritten = 35;

	set := s.getHashedSet(object)
	return set.GetObjectNInfo(ctx, bucket, object, rs, h, opts)
}

// PutObject - writes an object to hashedSet based on the object name.
func (s *erasureSets) PutObject(ctx context.Context, bucket string, object string, data *PutObjReader, opts ObjectOptions) (objInfo ObjectInfo, err error) {

    its own IDN mapping table in the library.

 *  New: Prefer the client's configured precedence order for TLS cipher suites. (OkHttp used to
    prefer the JDK’s precedence order.) This change may cause your HTTP calls to negotiate a
    different cipher suite than before! OkHttp's defaults cipher suites are selected for good
    security and performance.
