Ancak, birçok farklı function veya class tanımlamak zorunda kalmadan, dependency üzerinde bazı parametreler ayarlamak isteyebileceğiniz durumlar olabilir.

Örneğin, query parametresi `q`'nun belirli bir sabit içeriği barındırıp barındırmadığını kontrol eden bir dependency istediğimizi düşünelim.

Ama bu sabit içeriği parametreleştirebilmek istiyoruz.

Но бывают случаи, когда нужно задавать параметры зависимости, не объявляя много разных функций или классов.

Представим, что нам нужна зависимость, которая проверяет, содержит ли query-параметр `q` некоторое фиксированное содержимое.

Но при этом мы хотим иметь возможность параметризовать это фиксированное содержимое.

## «Вызываемый» экземпляр { #a-callable-instance }

    val encodedPathSegments: List<String> = httpUrl.encodedPathSegments
    val pathSegments: List<String> = httpUrl.pathSegments
    val encodedQuery: String? = httpUrl.encodedQuery
    val query: String? = httpUrl.query
    val querySize: Int = httpUrl.querySize
    val queryParameter: String? = httpUrl.queryParameter("")
    val queryParameterNames: Set<String> = httpUrl.queryParameterNames

### 「dependant」での依存関係の宣言 { #declare-the-dependency-in-the-dependant }

*path operation 関数*のパラメータに`Body`や`Query`などを使用するのと同じように、新しいパラメータに`Depends`を使用することができます:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

関数のパラメータに`Depends`を使用するのは`Body`や`Query`などと同じですが、`Depends`の動作は少し異なります。

`Depends`は１つのパラメータしか与えられません。

このパラメータは関数のようなものである必要があります。

在上面的範例中，輸入模型是 Pydantic v1，輸出模型（於 `response_model=ItemV2` 定義）是 Pydantic v2。

### Pydantic v1 參數 { #pydantic-v1-parameters }

若你需要在 Pydantic v1 模型上使用 FastAPI 的參數工具（例如 `Body`、`Query`、`Form` 等），在完成遷移到 Pydantic v2 之前，可以從 `fastapi.temp_pydantic_v1_params` 匯入：

{* ../../docs_src/pydantic_v1_in_v2/tutorial004_an_py310.py hl[4,18] *}
