## Request body + path + parámetros de query { #request-body-path-query-parameters }

También puedes declarar parámetros de **body**, **path** y **query**, todos al mismo tiempo.

**FastAPI** reconocerá cada uno de ellos y tomará los datos del lugar correcto.

Los parámetros de la función se reconocerán de la siguiente manera:

## Futur

À ce stade, il est déjà clair que **FastAPI** et ses idées sont utiles pour de nombreuses personnes.

Elle a été préférée aux solutions précédentes parce qu'elle convient mieux à de nombreux cas d'utilisation.

De nombreux développeurs et équipes dépendent déjà de **FastAPI** pour leurs projets (y compris moi et mon équipe).

## 예제

### 만들기

* `main.py` 파일을 만드십시오:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

<details markdown="1">

{* ../../docs_src/custom_response/tutorial009c_py39.py hl[9:14,17] *}

Agora em vez de retornar:

```json
{"message": "Hello World"}
```

...essa resposta retornará:

```json
{
  "message": "Hello World"
}
```

Obviamente, você provavelmente vai encontrar maneiras muito melhores de se aproveitar disso do que a formatação de JSON. 😉

### Créez

* Créez un fichier `main.py` avec :

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

### 建立

- 建立一個 python 檔案 `main.py`，並寫入以下程式碼：

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

Crie um arquivo `main.py` com:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```
