Um dies zu erreichen, können Sie die Kommandozeilenoption `--root-path` wie folgt verwenden:

<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`.

### 提供 `root_path`

为此，要以如下方式使用命令行选项 `--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>

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`。

### Use your tags

Use the `tags` parameter with your *path operations* (and `APIRouter`s) to assign them to different tags:

```Python hl_lines="21  26"
{!../../docs_src/metadata/tutorial004.py!}
```

/// info
