* `status_code` - `int` のHTTPステータスコード。
* `headers` - 文字列の `dict` 。
* `media_type` - メディアタイプを示す `str` 。例えば `"text/html"` 。

FastAPI (実際にはStarlette) は自動的にContent-Lengthヘッダーを含みます。また、media_typeに基づいたContent-Typeヘッダーを含み、テキストタイプのためにcharsetを追加します。

```Python hl_lines="1  18"

```

### `HTMLResponse`

上で読んだように、テキストやバイトを受け取り、HTMLレスポンスを返します。

### `PlainTextResponse`

  // a network host (e.g. "foo.bar.com") or "wildcard", which is a domain name
  // prefixed with a single wildcard label (e.g. "*.foo.com").
  // The wildcard character '*' must appear by itself as the first DNS label and
  // matches only a single label. You cannot have a wildcard label by itself (e.g. Host == "*").
  // Requests will be matched against the Host field in the following way:

 * <p><b>Warning:</b> Unlike {@code Multiset}, entries whose values are zero are not automatically
 * removed from the map. Instead they must be removed manually with {@link #removeAllZeros}.

public final class AtomicLongMap<K> implements Serializable {
  private final ConcurrentHashMap<K, AtomicLong> map;

* `media_type` - A `str` giving the media type. E.g. `"text/html"`.

FastAPI (actually Starlette) will automatically include a Content-Length header. It will also include a Content-Type header, based on the `media_type` and appending a charset for text types.

```Python hl_lines="1  18"

```

### `HTMLResponse`

Takes some text or bytes and returns an HTML response, as you read above.

		r[k] = v
	}
	return r
}

// URI scheme constants.
const (
	httpScheme  = "http"
	httpsScheme = "https"
)

// nopCharsetConverter is a dummy charset convert which just copies input to output,
// it is used to ignore custom encoding charset in S3 XML body.
func nopCharsetConverter(label string, input io.Reader) (io.Reader, error) {
	return input, nil
}

// xmlDecoder provide decoded value in xml.

### Ajouter des types

Modifions une seule ligne de la version précédente.

Nous allons changer seulement cet extrait, les paramètres de la fonction, de :


```Python
    first_name, last_name
```

à :

```Python
    first_name: str, last_name: str
```

C'est tout.
