### Подключение `APIRouter` для `users` и `items` { #include-the-apirouters-for-users-and-items }

Теперь давайте подключим `router` из подмодулей `users` и `items`:

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[10:11] title["app/main.py"] *}

/// info | Примечание

`users.router` содержит `APIRouter` из файла `app/routers/users.py`.

## Kullanıcıyı alın { #get-the-user }

`get_current_user`, oluşturduğumuz (sahte) bir yardımcı (utility) fonksiyonu kullanacak; bu fonksiyon `str` olarak bir token alır ve Pydantic `User` modelimizi döndürür:

{* ../../docs_src/security/tutorial002_an_py310.py hl[19:22,26:27] *}

## Mevcut kullanıcıyı enjekte edin { #inject-the-current-user }

## 获取用户 { #get-the-user }

`get_current_user` 使用创建的（伪）工具函数，该函数接收 `str` 类型的令牌，并返回 Pydantic 的 `User` 模型：

{* ../../docs_src/security/tutorial002_an_py310.py hl[19:22,26:27] *}

## 注入当前用户 { #inject-the-current-user }

在*路径操作* 的 `Depends` 中使用 `get_current_user`：

{* ../../docs_src/security/tutorial002_an_py310.py hl[31] *}

注意，此处把 `current_user` 的类型声明为 Pydantic 的 `User` 模型。

这有助于在函数内部使用代码补全和类型检查。

@app.get("/users/me")
def read_current_user(credentials: HTTPBasicCredentials | None = Security(security)):
    if credentials is None:
        return {"msg": "Create an account first"}
    return {"username": credentials.username, "password": credentials.password}


client = TestClient(app)


def test_security_http_basic():
    response = client.get("/users/me", auth=("john", "secret"))

### Die `APIRouter` für `users` und `items` inkludieren { #include-the-apirouters-for-users-and-items }

Inkludieren wir nun die `router` aus diesen Submodulen `users` und `items`:

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[10:11] title["app/main.py"] *}

/// info | Info

`users.router` enthält den `APIRouter` in der Datei `app/routers/users.py`.

### 將 `users` 與 `items` 的 `APIRouter` 納入 { #include-the-apirouters-for-users-and-items }

現在，把子模組 `users` 與 `items` 的 `router` 納入：

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[10:11] title["app/main.py"] *}

/// info | 資訊

`users.router` 是位於 `app/routers/users.py` 檔案內的 `APIRouter`。

而 `items.router` 是位於 `app/routers/items.py` 檔案內的 `APIRouter`。

///

## Den Benutzer abrufen { #get-the-user }

`get_current_user` wird eine von uns erstellte (gefakte) Hilfsfunktion verwenden, welche einen Token vom Typ `str` entgegennimmt und unser Pydantic-`User`-Modell zurückgibt:

{* ../../docs_src/security/tutorial002_an_py310.py hl[19:22,26:27] *}

## Den aktuellen Benutzer einfügen { #inject-the-current-user }
