修复错误时，客户端或用户不能访问错误的内部信息，否则会造成安全隐患。

### 覆盖 `HTTPException` 错误处理器

同理，也可以覆盖 `HTTPException` 处理器。

例如，只为错误返回纯文本响应，而不是返回 JSON 格式的内容：

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

```

!!! note "技术细节"

    还可以使用 `from starlette.responses import PlainTextResponse`。

## Recap

You can integrate any third party NoSQL database, just using their standard packages.

## 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

![ReDoc](https://fastapi.tiangolo.com/img/index/index-02-redoc-simple.png)

## 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
