### Use the `RequestValidationError` body

The `RequestValidationError` contains the `body` it received with invalid data.

You could use it while developing your app to log the body and debug it, return it to the user, etc.

```Python hl_lines="14"
{!../../../docs_src/handling_errors/tutorial005.py!}
```

### Use o body do `RequestValidationError`.

O `RequestValidationError` contém o `body` que ele recebeu de dados inválidos.

Você pode utilizá-lo enquanto desenvolve seu app para conectar o *body* e debugá-lo, e assim retorná-lo ao usuário, etc.

Tente enviar um item inválido como este:

```JSON
{

### Den `RequestValidationError`-Body verwenden

Der `RequestValidationError` enthält den empfangenen `body` mit den ungültigen Daten.

Sie könnten diesen verwenden, während Sie Ihre Anwendung entwickeln, um den Body zu loggen und zu debuggen, ihn zum Benutzer zurückzugeben, usw.

```Python hl_lines="14"

```JSON hl_lines="12-15"
{
  "detail": [
    {
      "loc": [
        "body",
        "size"
      ],
      "msg": "value is not a valid integer",
      "type": "type_error.integer"
    }
  ],
  "body": {
    "title": "towel",
    "size": "XL"
  }
}
```

### 使用 `RequestValidationError` 的请求体

`RequestValidationError` 包含其接收到的无效数据请求的 `body` 。

开发时，可以用这个请求体生成日志、调试错误，并返回给用户。

```Python hl_lines="14"
{!../../../docs_src/handling_errors/tutorial005.py!}

```

现在试着发送一个无效的 `item`，例如：

```JSON
{
  "title": "towel",
  "size": "XL"
}

```

收到的响应包含 `body` 信息，并说明数据是无效的：

```JSON hl_lines="12-15"
{
  "detail": [
    {

}
```
