    @Test

Ici, [OpenAPI](https://github.com/OAI/OpenAPI-Specification) est une spécification qui dicte comment définir le schéma de votre API.

Cette définition de schéma inclut les chemins de votre API, les paramètres possibles qu’ils prennent, etc.

#### « Schéma » de données { #data-schema }

Le terme « schéma » peut également faire référence à la forme d’une donnée, comme un contenu JSON.

        });

然後用它來宣告你的路徑操作。

用法就和 `FastAPI` 類別一樣：

{* ../../docs_src/bigger_applications/app_an_py310/routers/users.py hl[6,11,16] title["app/routers/users.py"] *}

你可以把 `APIRouter` 想成是「迷你版的 `FastAPI`」類別。

所有相同的選項都支援。

同樣的 `parameters`、`responses`、`dependencies`、`tags` 等全都可用。

/// tip | 提示

在這個範例中，變數名叫 `router`，但你可以用任何你想用的名稱。

///

我們稍後會把這個 `APIRouter` 加進主要的 `FastAPI` 應用程式中，但先來看看相依性與另一個 `APIRouter`。

## 相依性 { #dependencies }

    testSortDescending(new char[] {'A', '1', 'B', '2'}, 1, 3, new char[] {'A', 'B', '1', '2'});
  }

  public void testToArray() {
    // need explicit type parameter to avoid javac warning!?
    List<Character> none = Arrays.<Character>asList();
    assertThat(Chars.toArray(none)).isEqualTo(EMPTY);

    List<Character> one = Arrays.asList((char) 1);
