### Testen des aktuellen `root_path` { #checking-the-current-root-path }

Sie können den aktuellen `root_path` abrufen, der von Ihrer Anwendung für jeden Request verwendet wird. Er ist Teil des `scope`-<abbr title="Dictionary – Zuordnungstabelle: In anderen Sprachen auch Hash, Map, Objekt, Assoziatives Array genannt">Dictionarys</abbr> (das ist Teil der ASGI-Spezifikation).

/// 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。

然后，如果你这样启动 Uvicorn：

### [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.
