## Aktualizacja przykładu

Zmodyfikuj teraz plik `main.py`, aby otrzmywał treść (body) żądania `PUT`.

Zadeklaruj treść żądania, używając standardowych typów w Pythonie dzięki Pydantic.

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float

## Пример обновления

Теперь измените файл `main.py`, чтобы получить тело ответа из `PUT` запроса.

Объявите тело, используя стандартную типизацию Python, спасибо Pydantic.

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float

## 示例升级

现在修改 `main.py` 文件来从 `PUT` 请求中接收请求体。

我们借助 Pydantic 来使用标准的 Python 类型声明请求体。

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float

## Példa frissítése

Módosítsuk a `main.py` fájlt, hogy `PUT` kérések esetén tudjon body-t fogadni.

Deklaráld a body-t standard Python típusokkal, a Pydantic-nak köszönhetően.

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float

Ahora modifica el archivo `main.py` para recibir un <abbr title="cuerpo del mensaje HTTP">body</abbr> del `PUT` request.

Declara el body usando las declaraciones de tipo estándares de Python gracias a Pydantic.

```Python hl_lines="2  7-10  23-25"
from fastapi import FastAPI
from pydantic import BaseModel
from typing import Union

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float

## Evoluindo o Exemplo

Agora modifique o arquivo `main.py` para receber um corpo para uma requisição `PUT`.

Declare o corpo utilizando tipos padrão Python, graças ao Pydantic.

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float

Pydantic sayəsində standart Python tiplərindən istifadə edərək <abbr title="Gövdə: Body ">gövdə</abbr>ni müəyyən edək.

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float

## Nâng cấp ví dụ

Bây giờ sửa tệp tin `main.py` để nhận body từ một request `PUT`.

Định nghĩa của body sử dụng kiểu dữ liệu chuẩn của Python, cảm ơn Pydantic.

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float
