クエリパラメータ `tool` が許可されていないことを通知する**エラー**レスポンスが返されます。

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["query", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus"
        }
    ]
}
```

## まとめ

**FastAPI**では、**クエリパラメータ**を宣言するために、**Pydanticモデル**を使用できます。😎

```json
{

他们将收到一个**错误**响应，告诉他们查询参数 `tool` 是不允许的：

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["query", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus"
        }
    ]
}
```

## 总结

你可以使用 **Pydantic 模型**在 **FastAPI** 中声明**查询参数**。😎

/// tip

剧透警告：你也可以使用 Pydantic 模型来声明 cookie 和 headers，但你将在本教程的后面部分阅读到这部分内容。🤫

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["cookie", "santa_tracker"],
            "msg": "Extra inputs are not permitted",
            "input": "good-list-please",
        }
    ]
}
```

## 요약

    List<List<Integer>> input = newArrayList(list1, list2);

    FluentIterable<Integer> result = FluentIterable.concat(input);
    assertEquals(asList(1, 4), newArrayList(result));

    // Now change the inputs and see result dynamically change as well

    list1.add(2);
    List<Integer> list3 = newArrayList(3);
    input.add(1, list3);

        SmbSession result = transport.getSmbSession(ctx);
        assertSame(session, result);
        verify(transport).getSmbSession(eq(ctx));
    }

    // Edge inputs: null context returns null session per mock setup
    @Test
    @DisplayName("getSmbSession(ctx) with null context returns null as stubbed")
    void getSmbSession_byContext_null() {
