**FastAPI** 將會從請求的**查詢參數**中**提取**出**每個欄位**的資料，並將其提供給你定義的 Pydantic 模型。

## 查看文件

你可以在 `/docs` 頁面的 UI 中查看查詢參數：

<div class="screenshot">
<img src="/img/tutorial/query-param-models/image01.png">
</div>

## 禁止額外的查詢參數

在一些特殊的使用場景中（可能不是很常見），你可能希望**限制**你要收到的查詢參數。

你可以使用 Pydantic 的模型設定來 `forbid`（禁止）任何 `extra`（額外）欄位：
