이 매개변수들은 **FastAPI**가 의존성을 "해결"하기 위해 사용할 것입니다

함수와 클래스 두 가지 방식 모두, 아래 요소를 갖습니다:

* `문자열`이면서 선택사항인 쿼리 매개변수 `q`.
* 기본값이 `0`이면서 `정수형`인 쿼리 매개변수 `skip`
* 기본값이 `100`이면서 `정수형`인 쿼리 매개변수 `limit`

두 가지 방식 모두, 데이터는 변환, 검증되고 OpenAPI 스키마에 문서화됩니다.

## 사용해봅시다!

이제 아래의 클래스를 이용해서 의존성을 정의할 수 있습니다.

{* ../../docs_src/dependencies/tutorial002.py hl[19] *}

			//
			// S3 uses B-encoding (Base64) for non-ASCII-heavy metadata and Q-encoding
			// (quoted-printable) for mostly ASCII strings. Long strings are split at word
			// boundaries to fit RFC 2047’s 75-character limit, ensuring HTTP parser
			// compatibility.
			//
			// However, this splitting increases header size and can introduce errors, unlike Go’s
			// mime package in MinIO, which correctly encodes strings with fixed B/Q encodings,

## Advanced description from docstring { #advanced-description-from-docstring }

You can limit the lines used from the docstring of a *path operation function* for OpenAPI.

Adding an `\f` (an escaped "form feed" character) causes **FastAPI** to truncate the output used for OpenAPI at this point.

	return target.initOnce.Do(target.initMQTT)
}

func (target *MQTTTarget) initMQTT() error {
	args := target.args

	// Using hex here, to make sure we avoid 23
	// character limit on client_id according to
	// MQTT spec.
	clientID := fmt.Sprintf("%x", time.Now().UnixNano())

	options := mqtt.NewClientOptions().
		SetClientID(clientID).
		SetCleanSession(true).
		SetUsername(args.User).

constraints.AssertTrue.message = {item} सही होना चाहिए।
constraints.DecimalMax.message = {item} {value} से कम होना चाहिए।
constraints.DecimalMin.message = {item} {value} से अधिक होना चाहिए।
constraints.Digits.message = {item} एक संख्या होनी चाहिए। (अपेक्षित: <number>.<number>)
constraints.Future.message = {item} भविष्य का मान होना चाहिए।
constraints.Max.message = {item} {value} से कम या बराबर होना चाहिए।

constraints.AssertTrue.message = {item} harus bernilai true.
constraints.DecimalMax.message = {item} harus kurang dari {value}.
constraints.DecimalMin.message = {item} harus lebih dari {value}.
constraints.Digits.message = {item} harus berupa angka. (expected: <number>.<number>)
constraints.Future.message = {item} harus berupa nilai masa depan.
constraints.Max.message = {item} harus kurang dari atau sama dengan {value}.

En ambos casos, tendrá:

* Un parámetro de query `q` opcional que es un `str`.
* Un parámetro de query `skip` que es un `int`, con un valor por defecto de `0`.
* Un parámetro de query `limit` que es un `int`, con un valor por defecto de `100`.

En ambos casos, los datos serán convertidos, validados, documentados en el esquema de OpenAPI, etc.
