它可以是 `async def`，也可以是一般的 `def`，**FastAPI** 都能正確處理。

在此例中，任務函式會寫入檔案（模擬寄送電子郵件）。

由於寫入操作未使用 `async` 與 `await`，因此以一般的 `def` 定義該函式：

{* ../../docs_src/background_tasks/tutorial001_py310.py hl[6:9] *}

## 新增背景任務 { #add-the-background-task }

在路徑操作函式內，使用 `.add_task()` 將任務函式加入背景任務物件：

{* ../../docs_src/background_tasks/tutorial001_py310.py hl[14] *}

`.add_task()` 的引數包括：

* 要在背景執行的任務函式（`write_notification`）。

      // This is the size needed to add the replacement, not the full size
      // needed by the string. We only regrow when we absolutely must, and
      // when we do grow, grow enough to avoid excessive growing. Grow.

    @Test
    public void testReadFiletime() throws IOException {

        long time = System.currentTimeMillis();
        BigInteger filetime = BigInteger.valueOf(time)

                .multiply(BigInteger.valueOf(10000L));

        byte[] data = new byte[8];
        long low = filetime.longValue();

### Custom OpenAPI *path operation* schema { #custom-openapi-path-operation-schema }

The dictionary in `openapi_extra` will be deeply merged with the automatically generated OpenAPI schema for the *path operation*.

So, you could add additional data to the automatically generated schema.

- create a plugin processor
- directory
- jar
- hooks for loading

- I could make an annotation that marked another class as its plugin discoverer, I could just add it to
  the component descriptor and when it's loaded we can add the discoverer, that would be simpler. I could
  also do this with the lister as well
