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。🤫
