它等价于以下导入语句：

```Python
from main import app
```

///

每种 ASGI 服务器程序通常都会有类似的命令，您可以在它们的官方文档中找到更多信息。

/// warning

Uvicorn 和其他服务器支持 `--reload` 选项，该选项在开发过程中非常有用。

但 `--reload` 选项会消耗更多资源，且相对不稳定。

它对于**开发阶段**非常有帮助，但在**生产环境**中**不应该**使用。

///

## 部署概念

这些示例运行服务器程序（例如 Uvicorn），启动**单个进程**，在所有 IP（`0.0.0.0`）上监听预定义端口（例如`80`）。

这是基本思路。 但您可能需要处理一些其他事情，例如：
