# Usar el Request Directamente { #using-the-request-directly }

Hasta ahora, has estado declarando las partes del request que necesitas con sus tipos.

Tomando datos de:

* El path como parámetros.
* Headers.
* Cookies.
* etc.

Y al hacerlo, **FastAPI** está validando esos datos, convirtiéndolos y generando documentación para tu API automáticamente.

Pero hay situaciones donde podrías necesitar acceder al objeto `Request` directamente.

## Context

In Gradle we often need to serialize in-memory objects for caching, or to transmit them across process barriers, etc.
Java serialization is one way to implement this, however, despite its simplicity of implementation, it has several drawbacks:

- **Performance:**
Java's built-in serialization mechanism is often slower compared to other serialization solutions.
This is due to Java's use of reflection and the need to maintain a lot of metadata.

```

### 3. Failure after conversion
If the conversion is successful, but the generated model is wrong, then state what is wrong:

- Model produces wrong results and/or has lesser accuracy.
- Model produces correct results, but it is slower than expected.

### 4. (optional) RNN conversion support
If converting TF RNN to TFLite fused RNN ops, please prefix [RNN] in the title.

                return result;

/// warning

When you return a `Response` directly, like in the example above, it will be returned directly.

It won't be serialized with a model, etc.

Make sure it has the data you want it to have, and that the values are valid JSON (if you are using `JSONResponse`).

///

/// note | Technical Details

You could also use `from starlette.responses import JSONResponse`.
