/// warning | "Attention"

Lorsque vous renvoyez une `Response` directement, comme dans l'exemple ci-dessus, elle sera renvoyée directement.

Elle ne sera pas sérialisée avec un modèle.

Assurez-vous qu'il contient les données souhaitées et que les valeurs soient dans un format JSON valides (si vous utilisez une `JSONResponse`).

///

<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"
}
```

### Festlegen des `root_path` in der FastAPI-Anwendung

<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。
