final String code = userInfo.getId();
                        final UserInfo oldUserInfo = userInfoMap.get(code);
                        if (oldUserInfo != null) {
                            userInfo.setCreatedAt(oldUserInfo.getCreatedAt());
                        }

# 调试

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`

在你的 FastAPI 应用中直接导入 `uvicorn` 并运行：

{* ../../docs_src/debugging/tutorial001.py hl[1,15] *}

### 关于 `__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
```
