👥 📣 🎁 🔢 🆎 `SecurityScopes`, 🗄 ⚪️➡️ `fastapi.security`.

👉 `SecurityScopes` 🎓 🎏 `Request` (`Request` ⚙️ 🤚 📨 🎚 🔗).

```Python hl_lines="8  105"
{!../../../docs_src/security/tutorial005.py!}
```

## ⚙️ `scopes`

🔢 `security_scopes` 🔜 🆎 `SecurityScopes`.

该依赖项函数本身不需要作用域，因此，可以使用 `Depends` 和 `oauth2_scheme`。不需要指定安全作用域时，不必使用 `Security`。

此处还声明了从 `fastapin.security` 导入的 `SecurityScopes` 类型的特殊参数。

`SecuriScopes` 类与 `Request` 类似（`Request` 用于直接提取请求对象）。

```Python hl_lines="8  105"
{!../../../docs_src/security/tutorial005.py!}
```

## 使用 `scopes`

参数 `security_scopes` 的类型是 `SecurityScopes`。

它的属性 `scopes`  是作用域列表，所有依赖项都把它作为子依赖项。也就是说所有**依赖**……这听起来有些绕，后文会有解释。
