此处还声明了从 `fastapi.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）。

{* ../../docs_src/security/tutorial005.py hl[8,105] *}

## 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。

- Modify directory listing operations for caching
- Update change notification handling

### Phase 5: RDMA (SMB Direct) Support
**Priority: LOW** | **Estimated Effort: 8-10 weeks**

RDMA provides high-speed, low-latency data transfer for supported network adapters.
