이전 코드 예제로 돌아가서, **FastAPI**는 다음처럼 처리합니다:

* `GET` 및 `PUT` 요청에 `item_id`가 경로에 있는지 검증.
* `GET` 및 `PUT` 요청에 `item_id`가 `int` 타입인지 검증.
    * 그렇지 않다면 클라이언트는 유용하고 명확한 에러를 볼 수 있습니다.
* `GET` 요청에 `q`라는 선택적인 쿼리 매개변수가 검사(`http://127.0.0.1:8000/items/foo?q=somequery`처럼).
    * `q` 매개변수는 `= None`으로 선언되었기 때문에 선택사항입니다.
    * `None`이 없다면 필수사항입니다(`PUT`의 경우와 마찬가지로).
* `/items/{item_id}`으로의 `PUT` 요청은 본문을 JSON으로 읽음:
    * `name`을 필수 속성으로 갖고 `str` 형인지 검사.

        switch (values[0].toUpperCase(Locale.ROOT)) {
        case "GET":
            return curlHelper.get(path);
        case "POST":
            return curlHelper.post(path);
        case "PUT":
            return curlHelper.put(path);
        case "DELETE":
            return curlHelper.delete(path);
        default:
            break;
        }
        return null;
    }

به مثال قبلی باز می‌گردیم، در این مثال **FastAPI** موارد زیر را انجام می‌دهد:

* اعتبارسنجی اینکه پارامتر `item_id` در مسیر درخواست‌های `GET` و `PUT` موجود است.
* اعتبارسنجی اینکه پارامتر `item_id` در درخواست‌های `GET` و `PUT` از نوع `int` است.
    * اگر غیر از این موارد باشد، سرویس‌گیرنده خطای مفید و مشخصی دریافت خواهد کرد.
