回到前面的的程式碼範例，**FastAPI** 還會：

- 驗證 `GET` 和 `PUT` 請求路徑中是否包含 `item_id`。
- 驗證 `GET` 和 `PUT` 請求中的 `item_id` 是否是 `int` 型別。
    - 如果驗證失敗，將會返回清楚有用的錯誤訊息。
- 查看 `GET` 請求中是否有命名為 `q` 的查詢參數 (例如 `http://127.0.0.1:8000/items/foo?q=somequery`)。
    - 因為 `q` 參數被宣告為 `= None`，所以是選填的。
    - 如果沒有宣告 `None`，則此參數將會是必填 (例如 `PUT` 範例的請求 body)。
- 對於 `PUT` 的請求 `/items/{item_id}`，將會讀取 body 為 JSON：
    - 驗證是否有必填屬性 `name` 且型別是 `str`。

    * ReDoc.

Pour revenir à l'exemple de code précédent, **FastAPI** permet de :

* Valider que `item_id` existe dans le chemin des requêtes `GET` et `PUT`.
* Valider que `item_id` est de type `int` pour les requêtes `GET` et `PUT`.
    * Si ce n'est pas le cas, le client voit une erreur utile et claire.
