## `TrustedHostMiddleware`

Erzwingt, dass alle eingehenden Requests einen korrekt gesetzten `Host`-Header haben, um sich vor HTTP-Host-Header-Angriffen zu schützen.

{* ../../docs_src/advanced_middleware/tutorial002.py hl[2,6:8] *}

Die folgenden Argumente werden unterstützt:

{* ../../docs_src/configure_swagger_ui/tutorial001.py hl[3] *}

...그럼 Swagger UI에서 더 이상 구문 강조 기능이 표시되지 않습니다:

## 테마 변경

동일한 방식으로 `"syntaxHighlight.theme"` 키를 사용하여 구문 강조 테마를 설정할 수 있습니다 (중간에 점이 포함된 것을 참고하십시오).

{* ../../docs_src/configure_swagger_ui/tutorial002.py hl[3] *}

이 설정은 구문 강조 색상 테마를 변경합니다:

`Header` "👭" 🎓 `Path`, `Query` & `Cookie`. ⚫️ 😖 ⚪️➡️ 🎏 ⚠ `Param` 🎓.

Aqui estamos incluindo ele na mensagem apenas para fins de demonstração.

{* ../../docs_src/behind_a_proxy/tutorial001.py hl[8] *}

Então, se você iniciar o Uvicorn com:

<div class="termy">

```console
$ fastapi run main.py --root-path /api/v1

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

First, write all your **FastAPI** application as normally:

{* ../../docs_src/extending_openapi/tutorial001.py hl[1,4,7:9] *}

### Generate the OpenAPI schema { #generate-the-openapi-schema }

Then, use the same utility function to generate the OpenAPI schema, inside a `custom_openapi()` function:

{* ../../docs_src/extending_openapi/tutorial001.py hl[2,15:21] *}

### Modify the OpenAPI schema { #modify-the-openapi-schema }

{* ../../docs_src/query_params/tutorial001.py hl[9] *}

La partie appelée requête (ou **query**) dans une URL est l'ensemble des paires clés-valeurs placées après le `?` , séparées par des `&`.

Par exemple, dans l'URL :

```

{* ../../docs_src/advanced_middleware/tutorial001.py hl[2,6] *}

## `TrustedHostMiddleware`

Impone que todas las requests entrantes tengan correctamente configurado el header `Host`, para proteger contra ataques de HTTP Host Header.

{* ../../docs_src/advanced_middleware/tutorial002.py hl[2,6:8] *}

Se soportan los siguientes argumentos:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[3] *}

## Declarar parámetros de `Header`

Luego declara los parámetros de header usando la misma estructura que con `Path`, `Query` y `Cookie`.

Puedes definir el valor por defecto así como toda la validación extra o los parámetros de anotaciones:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[9] *}

/// note | Detalles Técnicos

{* ../../docs_src/path_params/tutorial005.py hl[17] *}

#### Obtenha o *valor de enumerate*

Você pode ter o valor exato de enumerate (um `str` nesse caso) usando `model_name.value`, ou em geral, `your_enum_member.value`:

{* ../../docs_src/path_params/tutorial005.py hl[20] *}
