## Mehrere Body-Parameter

Im vorherigen Beispiel erwartete die *Pfadoperation* einen JSON-Body mit den Attributen eines `Item`s, etwa:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

Aber Sie können auch mehrere Body-Parameter deklarieren, z. B. `item` und `user`:

    assert response.status_code == 400, response.text
    assert response.json() == {"detail": "X-Token header invalid"}
