/// note | 技术细节

ASGI 规范为这种用例定义了 `root_path`。

命令行选项 `--root-path` 会提供该 `root_path`。

///

### 查看当前的 `root_path` { #checking-the-current-root-path }

你可以获取应用在每个请求中使用的当前 `root_path`，它是 `scope` 字典的一部分（ASGI 规范的一部分）。

这里我们把它包含在响应消息中仅用于演示。

{* ../../docs_src/behind_a_proxy/tutorial001_py310.py hl[8] *}

然后，如果你这样启动 Uvicorn：

<div class="termy">

```console

Have a simple and easy to use routing system.

### [Requests](https://requests.readthedocs.io) { #requests }

**FastAPI** is not actually an alternative to **Requests**. Their scope is very different.

It would actually be common to use Requests *inside* of a FastAPI application.

But still, FastAPI got quite some inspiration from Requests.

}

そして `--root-path` コマンドラインオプションは、その `root_path` を提供します。

///

### 現在の `root_path` の確認 { #checking-the-current-root-path }

各リクエストでアプリケーションが使用している現在の `root_path` は取得できます。これは（ASGI 仕様の一部である）`scope` 辞書に含まれます。

ここではデモのため、メッセージに含めています。
