在這個例子中，「Proxy」可以是 **Traefik**。而伺服器可以是以 **Uvicorn** 啟動的 FastAPI CLI，運行你的 FastAPI 應用。

### 提供 `root_path` { #providing-the-root-path }

要達成這一點，你可以像這樣使用命令列選項 `--root-path`：

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

# functionality instead.
tfrun() { "$@"; }

if [[ $(uname -s) = MSYS_NT* ]]; then
  source ./ci/official/utilities/windows.sh
  echo 'Converting MSYS Linux-like paths to Windows paths (for Docker, Python, etc.)'
  source <(python ./ci/official/utilities/convert_msys_paths_to_win_paths.py --whitelist-prefix TFCI_)
fi

# Run all "tfrun" commands under Docker. See setup_docker.sh for details
