/// note | 技术细节

ASGI 规范定义的 `root_path` 就是为了这种用例。

并且 `--root-path` 命令行选项支持 `root_path`。

///

### 查看当前的 `root_path`

获取应用为每个请求使用的当前 `root_path`，这是 `scope` 字典的内容（也是 ASGI 规范的内容）。

我们在这里的信息里包含 `roo_path` 只是为了演示。

{* ../../docs_src/behind_a_proxy/tutorial001.py hl[8] *}

然后，用以下命令启动 Uvicorn：

<div class="termy">

```console
$ uvicorn main:app --root-path /api/v1
