你可以在编辑器中连接调试器，例如使用 Visual Studio Code 或 PyCharm。

## 调用 `uvicorn` { #call-uvicorn }

在你的 FastAPI 应用中直接导入 `uvicorn` 并运行：

{* ../../docs_src/debugging/tutorial001_py310.py hl[1,15] *}

### 关于 `__name__ == "__main__"` { #about-name-main }

`__name__ == "__main__"` 的主要目的是使用以下代码调用文件时执行一些代码：

<div class="termy">

```console
$ python myapp.py
```

</div>

而当其它文件导入它时并不会被调用，像这样：

```Python
from myapp import app
```

## Start MinIO with Lambda target

Register MinIO with a Lambda function, we are calling our target name as `function`, but you may call it any other friendly name of your choice.
```
MINIO_LAMBDA_WEBHOOK_ENABLE_function=on MINIO_LAMBDA_WEBHOOK_ENDPOINT_function=http://localhost:5000 minio server /data &
...
...
MinIO Object Storage Server

```

### Avoid name collisions { #avoid-name-collisions }

We are importing the submodule `items` directly, instead of importing just its variable `router`.

This is because we also have another variable named `router` in the submodule `users`.
