!!! note
    Notice that as we communicate with the database using `await`, the *path operation function* is declared with `async`.

### About `{**note.dict(), "id": last_record_id}`

`note` is a Pydantic `Note` object.

`note.dict()` returns a `dict` with its data, something like:

```Python
{
    "text": "Some note",
    "completed": False,
}
```

```

!!! Note "笔记"

    注意，本例与数据库通信时使用 `await`，因此要把*路径操作函数*声明为异步函数（`asnyc`）。

### 关于 `{**note.dict(), "id": last_record_id}`

`note` 是 Pydantic `Note` 对象：

`note.dict()` 返回包含如下数据的**字典**：

```Python
{
    "text": "Some note",
    "completed": False,
}
```

但它不包含 `id` 字段。

因此要新建一个包含 `note.dict()` 键值对的**字典**：

```Python
{**note.dict()}
```

!!! note "Hinweis"
    Einige Responsecodes (siehe nächster Abschnitt) kennzeichnen, dass die Response keinen Body hat.

    FastAPI versteht das und wird in der OpenAPI-Dokumentation anzeigen, dass es keinen Responsebody gibt.

## Über HTTP-Statuscodes

!!! note "Hinweis"

// in addition to String() and AsInt64() accessors.
//
// The serialization format is:
//
// ```
// <quantity>        ::= <signedNumber><suffix>
//
// 	(Note that <suffix> may be empty, from the "" case in <decimalSI>.)
//
// <digit>           ::= 0 | 1 | ... | 9
// <digits>          ::= <digit> | <digit><digits>

它可以：

* 在响应中返回状态码
* 在 OpenAPI 概图（及用户界面）中存档：

<img src="/img/tutorial/response-status-code/image01.png">

!!! note "笔记"

    某些响应状态码表示响应没有响应体（参阅下一章）。

    FastAPI 可以进行识别，并生成表明无响应体的 OpenAPI 文档。

## 关于 HTTP 状态码

!!! note "笔记"

    如果已经了解 HTTP 状态码，请跳到下一章。

在 HTTP 协议中，发送 3 位数的数字状态码是响应的一部分。

这些状态码都具有便于识别的关联名称，但是重要的还是数字。

简言之：

      # This defines the action the controller will take when a pod is detected as broken.

      # labelPods will label all pods with <brokenPodLabelKey>=<brokenPodLabelValue>.
      # This is only capable of identifying broken pods; the user is responsible for fixing them (generally, by deleting them).
