Falls Sie Hypercorn verwenden, das hat auch die Option `--root-path`.

/// note | "Technische Details"

Die ASGI-Spezifikation definiert einen `root_path` für diesen Anwendungsfall.

Und die Kommandozeilenoption `--root-path` stellt diesen `root_path` bereit.

///

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

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

</div>

Hypercorn 也支持 `--root-path `选项。

/// 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）。
