FastAPI CLI 接收你的 Python 程序路径，自动检测包含 FastAPI 的变量（通常命名为 `app`）及其导入方式，然后启动服务。

在生产环境中，你应该使用 `fastapi run` 命令。🚀

在内部，**FastAPI CLI** 使用了 <a href="https://www.uvicorn.dev" class="external-link" target="_blank">Uvicorn</a>，这是一个高性能、适用于生产环境的 ASGI 服务器。😎

## `fastapi dev`

当你运行 `fastapi dev` 时，它将以开发模式运行。

默认情况下，它会启用**自动重载**，因此当你更改代码时，它会自动重新加载服务器。该功能是资源密集型的，且相较不启用时更不稳定，因此你应该仅在开发环境下使用它。

默认情况下，它将监听 IP 地址 `127.0.0.1`，这是你的机器与自身通信的 IP 地址（`localhost`）。
