응답은 다음과 비슷할 것입니다:

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

### FastAPI 앱에서 `root_path` 설정하기 { #setting-the-root-path-in-the-fastapi-app }

    q: Annotated[str | None, Query(max_length=50)] = None,

instead of:

```python

@app.get("/items/{item_id}")
async def read_item(
    item_id: int = Path(ge=1, description="The item ID"),
    q: str | None = Query(default=None, max_length=50),
):
    return {"message": "Hello World"}
```
