# Zusätzliche Responses in OpenAPI

/// warning | Achtung

Dies ist ein eher fortgeschrittenes Thema.

Wenn Sie mit **FastAPI** beginnen, benötigen Sie dies möglicherweise nicht.

///

Sie können zusätzliche Responses mit zusätzlichen Statuscodes, Medientypen, Beschreibungen, usw. deklarieren.

Diese zusätzlichen Responses werden in das OpenAPI-Schema aufgenommen, sodass sie auch in der API-Dokumentation erscheinen.

Und kopieren Sie die Ausgabe in die Variable `SECRET_KEY` (verwenden Sie nicht die im Beispiel).

Erstellen Sie eine Variable `ALGORITHM` für den Algorithmus, der zum Signieren des JWT-Tokens verwendet wird, und setzen Sie sie auf `"HS256"`.

Erstellen Sie eine Variable für das Ablaufdatum des Tokens.

Definieren Sie ein Pydantic-Modell, das im Token-Endpunkt für die Response verwendet wird.

* Document it as such in the OpenAPI schema (and so, in the user interfaces):

<img src="/img/tutorial/response-status-code/image01.png">

/// note

Some response codes (see the next section) indicate that the response does not have a body.

FastAPI knows this, and will produce OpenAPI docs that state there is no response body.

///

/// note

/**
 * An implementation of {@code Iterable} which throws an exception on all invocations of the {@link
 * #iterator()} method after the first, and whose iterator is always unmodifiable.
 *
 * <p>The {@code Iterable} specification does not make it absolutely clear what should happen on a
 * second invocation, so implementors have made various choices, including:
 *
 * <ul>
 *   <li>returning the same iterator again
 *   <li>throwing an exception of some kind

A "decorator" takes the function below and does something with it.

In our case, this decorator tells **FastAPI** that the function below corresponds to the **path** `/` with an **operation** `get`.

It is the "**path operation decorator**".

///

You can also use the other operations:

* `@app.post()`
* `@app.put()`
* `@app.delete()`

And the more exotic ones:

* `@app.options()`
* `@app.head()`

`secrets.compare_digest()` needs to take `bytes` or a `str` that only contains ASCII characters (the ones in English), this means it wouldn't work with characters like `á`, as in `Sebastián`.

To handle that, we first convert the `username` and `password` to `bytes` encoding them with UTF-8.

/// check | Inspirierte **FastAPI**

Zusätzliche Validierungen für Datentypen zu definieren, mithilfe des „Default“-Werts von Modellattributen. Dies verbessert die Editorunterstützung und war zuvor in Pydantic nicht verfügbar.
