from typing import Annotated

from fastapi import FastAPI, Query

app = FastAPI()


@app.get("/items/")
async def read_items(q: Annotated[str | None, Query(alias="item-query")] = None):
    results = {"items": [{"item_id": "Foo"}, {"item_id": "Bar"}]}
    if q:
        results.update({"q": q})

Le nom le plus proche serait `item_query`.

Mais vous avez vraiment envie que ce soit exactement `item-query`...

Pour cela vous pouvez déclarer un `alias`, et cet alias est ce qui sera utilisé pour trouver la valeur du paramètre :

{* ../../docs_src/query_params_str_validations/tutorial009.py hl[9] *}

## Déprécier des paramètres

Disons que vous ne vouliez plus utiliser ce paramètre désormais.
