from typing import Annotated

from fastapi import Body, FastAPI, status
from fastapi.responses import JSONResponse

app = FastAPI()

items = {"foo": {"name": "Fighters", "size": 6}, "bar": {"name": "Tenders", "size": 3}}


@app.put("/items/{item_id}")
async def upsert_item(
    item_id: str,
    name: Annotated[str | None, Body()] = None,
    size: Annotated[int | None, Body()] = None,
):
    if item_id in items:

```
http://localhost:8000/items/?q=foo&q=bar
```

würden Sie die mehreren `q`-*Query-Parameter*-Werte (`foo` und `bar`) in einer Python-`list` in Ihrer *Pfadoperation-Funktion* im *Funktionsparameter* `q` erhalten.

So wäre die <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr> zu dieser URL:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

Então, com uma URL como:

```
http://localhost:8000/items/?q=foo&q=bar
```

você receberia os múltiplos valores dos parâmetros de consulta `q` (`foo` e `bar`) em uma `list` Python dentro da sua função de operação de rota, no parâmetro da função `q`.

Assim, a resposta para essa URL seria:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

### Parallele Hamburger { #parallel-burgers }

Stellen wir uns jetzt vor, dass es sich hierbei nicht um „nebenläufige Hamburger“, sondern um „parallele Hamburger“ handelt.

Sie gehen los mit Ihrem Schwarm, um paralleles Fast Food zu bekommen.

Sie stehen in der Schlange, während mehrere (sagen wir acht) Kassierer, die gleichzeitig Köche sind, die Bestellungen der Leute vor Ihnen entgegennehmen.
