* 기본값이 `100`인 `int` 쿼리 매개변수 `limit`.

두 경우 모두 데이터는 변환되고, 검증되며, OpenAPI 스키마에 문서화되는 등 여러 처리가 적용됩니다.

## 사용하기 { #use-it }

이제 이 클래스를 사용해 의존성을 선언할 수 있습니다.

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[19] *}

**FastAPI**는 `CommonQueryParams` 클래스를 호출합니다. 그러면 해당 클래스의 "인스턴스"가 생성되고, 그 인스턴스가 함수의 매개변수 `commons`로 전달됩니다.

## 타입 어노테이션 vs `Depends` { #type-annotation-vs-depends }

위 코드에서 `CommonQueryParams`를 두 번 작성하는 방식에 주목하세요:

compatibility.

Starting with go1.19.txt, each API feature line must end in "#nnnnn"
giving the GitHub issue number of the proposal issue that accepted
the new API. This helps with our end-of-cycle audit of new APIs.
The same requirement applies to next/* (described below), which will
become a go1.XX.txt for XX >= 19.

The next/ directory contains the only files intended to be mutated.

        assertEquals(smbComNtTransaction.maxDataCount, SmbComTransaction.readInt4(dst, 15), "maxDataCount should be written correctly");
        assertEquals(smbComNtTransaction.parameterCount, SmbComTransaction.readInt4(dst, 19), "parameterCount should be written correctly");
        assertEquals(smbComNtTransaction.parameterOffset, SmbComTransaction.readInt4(dst, 23),
                "parameterOffset should be written correctly");

{"name":"Michael", "age": 31}
{"name":"Andy", "age": 30}

## Use it { #use-it }

Now you can declare your dependency using this class.

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[19] *}

**FastAPI** calls the `CommonQueryParams` class. This creates an "instance" of that class and the instance will be passed as the parameter `commons` to your function.

        "email": "******@****.***",
        "hashed_password": "$argon2id$v=19$m=65536,t=3,p=4$wagCPXjifgvUFBzq4hqe3w$CYaIb8sB+wtD+Vu/P4uod1+Qof8h+1g7bbDlBID48Rc",
        "disabled": False,
    },
    "alice": {
        "username": "alice",
        "full_name": "Alice Chains",
        "email": "******@****.***",
        "hashed_password": "$argon2id$v=19$m=65536,t=3,p=4$g2/AV1zwopqUntPKJavBFw$BwpRGDCyUHLvHICnwijyX8ROGoiUPwNKZ7915MeYfCE",

* 一个 `limit` 查询参数，是 `int` 类型，默认值为 `100`。

在两个例子下，数据都将被转换、验证、在 OpenAPI schema 上文档化，等等。

## 使用它 { #use-it }

现在，你可以使用这个类来声明你的依赖项了。

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[19] *}

**FastAPI** 调用 `CommonQueryParams` 类。这将创建该类的一个 "实例"，该实例将作为参数 `commons` 被传递给你的函数。

## 类型注解 vs `Depends` { #type-annotation-vs-depends }

注意，我们在上面的代码中编写了两次`CommonQueryParams`：

//// tab | Python 3.10+

	_ = x[storageMetricDelete-14]
	_ = x[storageMetricDeleteVersions-15]
	_ = x[storageMetricVerifyFile-16]
	_ = x[storageMetricWriteAll-17]
	_ = x[storageMetricDeleteVersion-18]
	_ = x[storageMetricWriteMetadata-19]
	_ = x[storageMetricUpdateMetadata-20]
	_ = x[storageMetricReadVersion-21]
	_ = x[storageMetricReadXL-22]
	_ = x[storageMetricReadAll-23]
	_ = x[storageMetricStatInfoFile-24]
	_ = x[storageMetricReadMultiple-25]

- 一個查詢參數 `limit`，型別為 `int`，預設為 `100`。

兩種情況下，資料都會被轉換、驗證，並記錄到 OpenAPI schema 中等。

## 如何使用 { #use-it }

現在你可以用這個類別來宣告你的相依性。

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[19] *}

**FastAPI** 會呼叫 `CommonQueryParams` 類別。這會建立該類別的一個「實例」，而該實例會以參數 `commons` 的形式傳給你的函式。

## 型別註解與 `Depends` { #type-annotation-vs-depends }

注意上面程式碼裡我們寫了兩次 `CommonQueryParams`：
