/// tip | Dica

Perceba que aqui estamos utilizando o `open()` da biblioteca padrão que não suporta `async` e `await`, e declaramos a operação de rota com o `def` básico.

## OpenAPI와 통합

모든 요청 선언, 검증과 의존성(및 하위 의존성)에 대한 요구 사항은 동일한 OpenAPI 스키마에 통합됩니다.

따라서 대화형 문서에 이러한 의존성에 대한 모든 정보 역시 포함하고 있습니다:

    } catch (_: InterruptedException) {
      Thread.currentThread().interrupt() // Retain interrupted status.
      throw InterruptedIOException()
    }

### 关于 `def` 对比 `async def`

*在这里，我们在路径操作函数*和依赖项中都使用着 SQLAlchemy 模型，它将与外部数据库进行通信。

这会需要一些“等待时间”。

但是由于 SQLAlchemy 不具有`await`直接使用的兼容性，因此类似于：

```Python
user = await db.query(User).first()
```

...相反，我们可以使用：

```Python
user = db.query(User).first()
```

然后我们应该声明*路径操作函数*和不带 的依赖关系`async def`，只需使用普通的`def`，如下：

			err = dc.Skip()
			if err != nil {
				err = msgp.WrapError(err)
				return
			}
		}
	}
	return
}

// EncodeMsg implements msgp.Encodable
func (z *healingTracker) EncodeMsg(en *msgp.Writer) (err error) {
	// map header, size 29
	// write "ID"
	err = en.Append(0xde, 0x0, 0x1d, 0xa2, 0x49, 0x44)
	if err != nil {
		return
	}
	err = en.WriteString(z.ID)
	if err != nil {

Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
