响应类似于：

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

### 在 FastAPI 应用中设置 `root_path` { #setting-the-root-path-in-the-fastapi-app }

或者，如果你无法提供类似 `--root-path` 的命令行选项，你可以在创建 FastAPI 应用时设置参数 `root_path`：

{* ../../docs_src/behind_a_proxy/tutorial002_py310.py hl[3] *}

# 並行処理と async / await { #concurrency-and-async-await }

*path operation 関数*のための `async def` 構文に関する詳細と、非同期コード、並行処理、並列処理の背景についてです。

## 急いでいますか？ { #in-a-hurry }

次のように `await` で呼び出すよう指示されているサードパーティライブラリを使っているなら:

```Python
results = await some_library()
```

*path operation 関数*は次のように `async def` で宣言します:

```Python hl_lines="2"
@app.get('/')
