Puedes definir manejadores de eventos (funciones) que necesitan ser ejecutadas antes de que la aplicación se inicie, o cuando la aplicación se está cerrando.

Estas funciones pueden ser declaradas con `async def` o `def` normal.

### Evento `startup` { #startup-event }

Para añadir una función que debería ejecutarse antes de que la aplicación inicie, declárala con el evento `"startup"`:

    @Override
    protected void setUp(TestInfo testInfo) throws Exception {
        super.setUp(testInfo);
        indexUpdateCallback = new FileListIndexUpdateCallbackImpl(null, null, 1);
    }

    /** Case 1: Normal merge (no duplicates) */
    @Test
    public void test_mergeResponseData_noOverwrite() {
        Map<String, Object> dataMap = new HashMap<>();
        dataMap.put("a", "A0");

            return true;
        }

        return false;
    }

    /**
     * Converts a crawling path to the appropriate protocol format.
     * Handles various path formats and adds proper protocol prefixes.
     *
     * @param path the original path to convert
     * @return the converted path with appropriate protocol prefix
     */

        this.commandDestroyTimeout = commandDestroyTimeout;
    }

    /**
     * Gets file extension from MIME type for creating temp files with proper extensions.
     * This helps ImageMagick correctly identify file formats.
     * @param mimeType The MIME type of the content.
     * @return The file extension including the dot (e.g., ".gif"), or empty string if unknown.

API 的用户（外部开发者）要在您的 API 内使用 POST 请求创建一条发票记录。

（假设）您的 API 将：

* 把发票发送至外部开发者的消费者
* 归集现金
* 把通知发送至 API 的用户（外部开发者）
    * 通过（从您的 API）发送 POST 请求至外部 API（即**回调**）来完成

## 常规 **FastAPI** 应用 { #the-normal-fastapi-app }

添加回调前，首先看下常规 API 应用是什么样子。

常规 API 应用包含接收 `Invoice` 请求体的*路径操作*，还有包含回调 URL 的查询参数 `callback_url`。

这部分代码很常规，您对绝大多数代码应该都比较熟悉了：
