Rufen Sie nun die Benutzerdaten aus der (gefakten) Datenbank ab, für diesen `username` aus dem Formularfeld.

Wenn es keinen solchen Benutzer gibt, geben wir die Fehlermeldung „Incorrect username or password“ zurück.

Für den Fehler verwenden wir die Exception `HTTPException`:

=== "Python 3.10+"

    ```Python hl_lines="3  79-81"
    {!> ../../../docs_src/security/tutorial003_an_py310.py!}

Now, get the user data from the (fake) database, using the `username` from the form field.

If there is no such user, we return an error saying "Incorrect username or password".

For the error, we use the exception `HTTPException`:

=== "Python 3.10+"

    ```Python hl_lines="3  79-81"
    {!> ../../../docs_src/security/tutorial003_an_py310.py!}
    ```

* **Validate** the returned data.
    * If the data is invalid (e.g. you are missing a field), it means that *your* app code is broken, not returning what it should, and it will return a server error instead of returning incorrect data. This way you and your clients can be certain that they will receive the data and the data shape expected.
* Add a **JSON Schema** for the response, in the OpenAPI *path operation*.
