回到前面的程式碼範例，**FastAPI** 會：

* 驗證 `GET` 與 `PUT` 請求的路徑中是否包含 `item_id`。
* 驗證 `GET` 與 `PUT` 請求中的 `item_id` 是否為 `int` 型別。
    * 如果不是，客戶端會看到清楚有用的錯誤。
* 在 `GET` 請求中檢查是否有名為 `q` 的可選查詢參數（如 `http://127.0.0.1:8000/items/foo?q=somequery`）。
    * 因為 `q` 參數被宣告為 `= None`，所以它是可選的。
    * 若沒有 `None`，則它會是必填（就像 `PUT` 時的 body）。
