### 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。

{* ../../docs_src/behind_a_proxy/tutorial002.py hl[3] *}

传递 `root_path` 给 `FastAPI` 与传递 `--root-path` 命令行选项给 Uvicorn 或 Hypercorn 一样。

### 关于 `root_path`

注意，服务器（Uvicorn）只是把 `root_path` 传递给应用。

/// note | Technische Details

Die ASGI-Spezifikation definiert einen `root_path` für diesen Anwendungsfall.

Und die Kommandozeilenoption `--root-path` stellt diesen `root_path` bereit.

///

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

/// note | Detalhes Técnicos

A especificação ASGI define um `root_path` para esse caso de uso.

E a opção de linha de comando `--root-path` fornece esse `root_path`.

///

### Verificando o `root_path` atual { #checking-the-current-root-path }

/// note | Технические детали

Спецификация ASGI определяет `root_path` для такого случая.

А опция командной строки `--root-path` передаёт этот `root_path`.

///

### Проверка текущего `root_path` { #checking-the-current-root-path }

Вы можете получить текущий `root_path`, используемый вашим приложением для каждого запроса, — он входит в словарь `scope` (часть спецификации ASGI).

/// note | Detalles Técnicos

La especificación ASGI define un `root_path` para este caso de uso.

Y la opción de línea de comandos `--root-path` proporciona ese `root_path`.

///

### Revisar el `root_path` actual { #checking-the-current-root-path }

/// note | Technical Details

The ASGI specification defines a `root_path` for this use case.

And the `--root-path` command line option provides that `root_path`.

///

### Checking the current `root_path` { #checking-the-current-root-path }

You can get the current `root_path` used by your application for each request, it is part of the `scope` dictionary (that's part of the ASGI spec).
