## Requestbody- + Pfad- + Query-Parameter { #request-body-path-query-parameters }

Sie können auch zur gleichen Zeit **Body-**, **Pfad-** und **Query-Parameter** deklarieren.

**FastAPI** wird jeden von ihnen korrekt erkennen und die Daten vom richtigen Ort holen.

Again, it will convert the data types, validate, document, etc.

## Multiple body params and query { #multiple-body-params-and-query }

Of course, you can also declare additional query parameters whenever you need, additional to any body parameters.

As, by default, singular values are interpreted as query parameters, you don't have to explicitly add a `Query`, you can just do:

```Python
q: Union[str, None] = None
```

## Mehrere Body-Parameter und Query-Parameter { #multiple-body-params-and-query }

Natürlich können Sie auch, wann immer Sie das brauchen, weitere Query-Parameter hinzufügen, zusätzlich zu den Body-Parametern.

Da einfache Werte standardmäßig als Query-Parameter interpretiert werden, müssen Sie `Query` nicht explizit hinzufügen, Sie können einfach schreiben:

```Python

from fastapi import FastAPI, Query

app = FastAPI()


@app.get("/items/")
async def read_items(q: list = Query(default=[])):
    query_items = {"q": q}

                            "name": "q",
                            "in": "query",
                        },
                        {
                            "required": False,
                            "schema": {
                                "anyOf": [{"type": "string"}, {"type": "null"}],
                                "title": "Last Query",
                            },
                            "name": "last_query",

    return item_id
