La mayoría de los headers estándar están separados por un carácter "guion", también conocido como el "símbolo menos" (`-`).

Pero una variable como `user-agent` es inválida en Python.

Así que, por defecto, `Header` convertirá los caracteres de los nombres de los parámetros de guion bajo (`_`) a guion (`-`) para extraer y documentar los headers.

## Use cases { #use-cases }

Some use cases include:

* Converting non-JSON request bodies to JSON (e.g. [`msgpack`](https://msgpack.org/index.html)).
* Decompressing gzip-compressed request bodies.
* Automatically logging all request bodies.
