# Body - Paramètres multiples

Maintenant que nous avons vu comment manipuler `Path` et `Query`, voyons comment faire pour le corps d'une requête, communément désigné par le terme anglais "body".

## Mélanger les paramètres `Path`, `Query` et body

Tout d'abord, sachez que vous pouvez mélanger les déclarations des paramètres `Path`, `Query` et body, **FastAPI** saura quoi faire.

Você pode definir parâmetros de Cookie da mesma maneira que define parâmetros com `Query` e `Path`.

## Importe `Cookie` { #import-cookie }

Primeiro importe `Cookie`:

{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[3] *}

## Declare parâmetros de `Cookie` { #declare-cookie-parameters }

Então declare os parâmetros de cookie usando a mesma estrutura que em `Path` e `Query`.

    session.close()


def generate_stream(query: str):
    for ch in query:
        yield ch
        time.sleep(0.1)


@app.get("/generate", dependencies=[Depends(get_user)])
def generate(query: str):

from typing import Annotated

from fastapi import FastAPI, Query

app = FastAPI()


@app.get("/items/")
async def read_items(
    q: Annotated[
        str | None,
        Query(
            title="Query string",
            description="Query string for the items to search in the database that have a good match",
            min_length=3,
        ),
    ] = None,
):

# Çerez (Cookie) Parametreleri

`Query` (Sorgu) ve `Path` (Yol) parametrelerini tanımladığınız şekilde çerez parametreleri tanımlayabilirsiniz.

## Import `Cookie`

Öncelikle, `Cookie`'yi projenize dahil edin:

{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[3] *}

## `Cookie` Parametrelerini Tanımlayın

Çerez parametrelerini `Path` veya `Query` tanımlaması yapar gibi tanımlayın.

                                "title": "Query string",
                                "description": "Query string for the items to search in the database that have a good match",
                            },
                            "name": "q",
                            "in": "query",
                        }
                    ],
                }
            }

    response = client.get("/users")
    assert response.status_code == 422
    assert response.json() == {
        "detail": [
            {
                "type": "missing",
                "loc": ["query", "token"],
                "msg": "Field required",
                "input": None,
            }
        ]
    }

`Header` es una clase "hermana" de `Path`, `Query` y `Cookie`. También hereda de la misma clase común `Param`.

Pero recuerda que cuando importas `Query`, `Path`, `Header`, y otros de `fastapi`, en realidad son funciones que retornan clases especiales.

///

/// info | Información

Para declarar headers, necesitas usar `Header`, porque de otra forma los parámetros serían interpretados como parámetros de query.
