你的回應模型可能有預設值，例如：

{* ../../docs_src/response_model/tutorial004_py310.py hl[9,11:12] *}

* `description: Union[str, None] = None`（或在 Python 3.10 中的 `str | None = None`）預設為 `None`。
* `tax: float = 10.5` 預設為 `10.5`。
* `tags: List[str] = []` 預設為空的 list：`[]`。

但如果這些值其實沒有被儲存，你可能想要在結果中省略它們。

例如，如果你在 NoSQL 資料庫中有包含許多選擇性屬性的模型，但你不想傳送充滿預設值的冗長 JSON 回應。

**OkHttp now supports Happy Eyeballs ([RFC 8305][rfc_8305]) for IPv4+IPv6 networks.** It attempts
both IPv6 and IPv4 connections concurrently, keeping whichever connects first.

**We’ve improved our Kotlin APIs.** You can skip the builder:

```kotlin

        FileSystemInformation info1 = response.getInfo();

        // Second read with different data
        buffer = prepareAllocationInfoBuffer();
        buffer[8] = 10; // Change some data

        int bytesRead2 = response.readDataWireFormat(buffer, 0, 20);
        FileSystemInformation info2 = response.getInfo();

        // Info should be updated
