Dies erfolgt nicht innerhalb jedes in OpenAPI enthaltenen JSON-Schemas, sondern außerhalb, in der *Pfadoperation*.

### Verwendung des Parameters `openapi_examples` { #using-the-openapi-examples-parameter }

Sie können die OpenAPI-spezifischen `examples` in FastAPI mit dem Parameter `openapi_examples` deklarieren, für:

* `Path()`
* `Query()`
* `Header()`
* `Cookie()`
* `Body()`
* `Form()`
* `File()`

To return a response with HTML directly from **FastAPI**, use `HTMLResponse`.

* Import `HTMLResponse`.
* Pass `HTMLResponse` as the parameter `response_class` of your *path operation decorator*.

{* ../../docs_src/custom_response/tutorial002_py39.py hl[2,7] *}

/// info

The parameter `response_class` will also be used to define the "media type" of the response.

In this case, the HTTP header `Content-Type` will be set to `text/html`.

 * <code>java.io.File</code> usage; a '/' at the beginning of the second
 * parameter will still use the server component of the first parameter. The
 * examples below illustrate the resulting URLs when this second contructor
 * argument is used.

### Kompakt { #short }

Es gibt für alles sensible **Defaultwerte**, mit optionaler Konfiguration überall. Alle Parameter können feinjustiert werden, damit sie tun, was Sie benötigen, und die API definieren, die Sie brauchen.

Aber standardmäßig **„funktioniert einfach alles“**.

* La documentación alternativa también reflejará el nuevo parámetro de query y body:

### Resumen { #recap }

En resumen, declaras **una vez** los tipos de parámetros, body, etc. como parámetros de función.

Lo haces con tipos estándar modernos de Python.

* A documentação alternativa também irá refletir o novo parâmetro da _query_ e o corpo:

### Recapitulando { #recap }

Resumindo, você declara **uma vez** os tipos dos parâmetros, corpo etc. como parâmetros de função.

Você faz isso com os tipos padrão do Python moderno.
