```JSON

Vous recevrez une réponse vous indiquant que les données sont invalides et contenant le corps reçu :

```JSON hl_lines="12-15"

现在试着发送一个无效的 `item`，例如：

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

收到的响应会告诉你数据无效，并包含收到的请求体：

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

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

You will receive a response telling you that the data is invalid containing the received body:

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

それは、パラメータが全くない呼び出し可能なものにも適用されます。パラメータのない*path operation関数*と同じように。

そこで、上で紹介した依存関係の"dependable" `common_parameters`を`CommonQueryParams`クラスに変更します:

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[11:15] *}

クラスのインスタンスを作成するために使用される`__init__`メソッドに注目してください:

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[12] *}

...以前の`common_parameters`と同じパラメータを持っています:

  }

  private ThreadPoolExecutor executorService;
  private CountDownLatch listenerLatch;
  private ExecutionListWrapper list;

  @Param Impl impl;

  @Param({"1", "5", "10"})
  int numListeners;

  private final Runnable listener =
      new Runnable() {
        @Override
        public void run() {
          listenerLatch.countDown();
        }
      };

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

Recibirás un response que te dirá que los datos son inválidos conteniendo el body recibido:

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

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

Você receberá uma *response* informando-o de que os dados são inválidos, e contendo o *body* recebido:

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