### ⚒ `root_path` FastAPI 📱

👐, 🚥 👆 🚫 ✔️ 🌌 🚚 📋 ⏸ 🎛 💖 `--root-path` ⚖️ 🌓, 👆 💪 ⚒ `root_path` 🔢 🕐❔ 🏗 👆 FastAPI 📱:

```Python hl_lines="3"

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

</div>

返回的响应如下：

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

### 在 FastAPI 应用里设置 `root_path`

还有一种方案，如果不能提供 `--root-path` 或等效的命令行选项，则在创建 FastAPI 应用时要设置 `root_path` 参数。

```Python hl_lines="3"

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

</div>

wäre die Response etwa:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

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

The response would be something like:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
