```python

Hier ist `needy` ein erforderlicher Query-Parameter vom Typ `str`.

Wenn Sie in Ihrem Browser eine URL wie:

```
http://127.0.0.1:8000/items/foo-item
```

... öffnen, ohne den benötigten Parameter `needy`, dann erhalten Sie einen Fehler wie den folgenden:

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],

* Dem `username`.
* Dem `password`.
* Einem optionalen `scope`-Feld als langem String, bestehend aus durch Leerzeichen getrennten Strings.
* Einem optionalen `grant_type` („Art der Anmeldung“).

!!! tip "Tipp"
    Die OAuth2-Spezifikation *erfordert* tatsächlich ein Feld `grant_type` mit dem festen Wert `password`, aber `OAuth2PasswordRequestForm` erzwingt dies nicht.
