Теперь получим данные о пользователе из (ненастоящей) базы данных, используя `username` из поля формы.

Если такого пользователя нет, то мы возвращаем ошибку "Incorrect username or password" (неверное имя пользователя или пароль).

Для ошибки используем исключение `HTTPException`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[3,79:81] *}

    assertTrue(
        "non-empty multiset.entrySet() iterator.hasNext() returned false", iterator.hasNext());

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`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[3,79:81] *}

### Das Passwort überprüfen { #check-the-password }

///

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`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[3,79:81] *}

### Check the password { #check-the-password }

///

Ahora, obtén los datos del usuario desde la base de datos (falsa), usando el `username` del campo del form.

Si no existe tal usuario, devolvemos un error diciendo "Incorrect username or password".

Para el error, usamos la excepción `HTTPException`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[3,79:81] *}

### Revisa el password { #check-the-password }
