<div class="termy">

```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)

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）。

<div class="termy">

```console
$ fastapi run main.py --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>

If you use Hypercorn, it also has the option `--root-path`.

!!! note "Technical Details"
    The ASGI specification defines a `root_path` for this use case.

    And the `--root-path` command line option provides that `root_path`.

<div class="termy">

```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>

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

!!! note "Technische Details"
    Die ASGI-Spezifikation definiert einen `root_path` für diesen Anwendungsfall.

<div class="termy">

```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)
