Maneja responses GZip para cualquier request que incluya `"gzip"` en el header `Accept-Encoding`.

El middleware manejará tanto responses estándar como en streaming.

## Optional File Upload { #optional-file-upload }

You can make a file optional by using standard type annotations and setting a default value of `None`:

## `UploadFile` with Additional Metadata { #uploadfile-with-additional-metadata }

Vamos a empezar desde donde lo dejamos en el capítulo anterior e incrementarlo.

## Acerca de JWT { #about-jwt }

JWT significa "JSON Web Tokens".

Es un estándar para codificar un objeto JSON en un string largo y denso sin espacios. Se ve así:

```

    call.execute().use { response ->
      assertThat(response.body.string()).isEqualTo("abc")
    }

    val expectedEvents = mutableListOf<KClass<out CallEvent>>()
    // Start out with standard events...
    expectedEvents += CallStart::class
    expectedEvents += ProxySelectStart::class
    expectedEvents += ProxySelectEnd::class
    expectedEvents += DnsStart::class
    expectedEvents += DnsEnd::class

 * invoke methods, they invoke methods on the {@code ForwardingSortedMultiset}.

 * <p>The {@code standard} methods and any collection views they return are not guaranteed to be
 * thread-safe, even when all of the methods that they depend on are thread-safe.

そして、Gunicorn互換の**Uvicornワーカー**クラスが、FastAPIが使えるように、Gunicornから送られてきたデータをASGI標準に変換する役割を担います。

## GunicornとUvicornをインストールする

<div class="termy">

```console
$ pip install "uvicorn[standard]" gunicorn

---> 100%

これによりUvicornと（高性能を得るための）標準（`standard`）の追加パッケージとGunicornの両方がインストールされます。

## UvicornのワーカーとともにGunicornを実行する

Gunicornを以下のように起動させることができます:
