Sie können es so verwenden:

=== "Python 3.10+"

    ```Python hl_lines="23-49"
    {!> ../../../docs_src/schema_extra_example/tutorial005_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="23-49"
    {!> ../../../docs_src/schema_extra_example/tutorial005_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="24-50"

You can use it like this:

=== "Python 3.10+"

    ```Python hl_lines="23-49"
    {!> ../../../docs_src/schema_extra_example/tutorial005_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="23-49"
    {!> ../../../docs_src/schema_extra_example/tutorial005_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="24-50"

	_ = x[HandlerGetMetrics-43]
	_ = x[HandlerGetResourceMetrics-44]
	_ = x[HandlerGetMemInfo-45]
	_ = x[HandlerGetProcInfo-46]
	_ = x[HandlerGetOSInfo-47]
	_ = x[HandlerGetPartitions-48]
	_ = x[HandlerGetNetInfo-49]
	_ = x[HandlerGetCPUs-50]
	_ = x[HandlerServerInfo-51]
	_ = x[HandlerGetSysConfig-52]
	_ = x[HandlerGetSysServices-53]
	_ = x[HandlerGetSysErrors-54]
	_ = x[HandlerGetAllBucketStats-55]
	_ = x[HandlerGetBucketStats-56]

Genauso können Sie den `HTTPException`-Handler überschreiben.

Zum Beispiel könnten Sie eine Klartext-Response statt JSON für diese Fehler zurückgeben wollen:

```Python hl_lines="3-4  9-11  22"
{!../../../docs_src/handling_errors/tutorial004.py!}
```

!!! note "Technische Details"
    Sie können auch `from starlette.responses import PlainTextResponse` verwenden.

	_ = x[ErrRemoteTargetNotFoundError-45]
	_ = x[ErrReplicationRemoteConnectionError-46]
	_ = x[ErrReplicationBandwidthLimitError-47]
	_ = x[ErrBucketRemoteIdenticalToSource-48]
	_ = x[ErrBucketRemoteAlreadyExists-49]
	_ = x[ErrBucketRemoteLabelInUse-50]
	_ = x[ErrBucketRemoteArnTypeInvalid-51]
	_ = x[ErrBucketRemoteArnInvalid-52]
	_ = x[ErrBucketRemoteRemoveDisallowed-53]
	_ = x[ErrRemoteTargetNotVersionedError-54]

## 範例升級

現在繼續修改 `main.py` 檔案，來接收一個帶有 body 的 `PUT` 請求。

我們使用 Pydantic 來使用標準的 Python 型別聲明請求。

```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

## 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

## 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

Deklarieren Sie den Body mithilfe von Standard-Python-Typen, dank 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
