<b>Requirement 3</b>:

<i>W</i>(<i>r</i>) must be a write <i>w</i> that is <i>visible</i> to <i>r</i>,
where visible means that both of the following hold:
</p>

<ol>
	<li><i>w</i> happens before <i>r</i>.</li>
	<li><i>w</i> does not happen before any other write <i>w'</i> (to <i>x</i>) that happens before <i>r</i>.</li>
</ol>

Eine weitere wichtige Funktion, benötigt von APIs, ist die Datenvalidierung, welche sicherstellt, dass die Daten unter gegebenen Umständen gültig sind. Zum Beispiel, dass ein Feld ein `int` ist und kein zufälliger String. Das ist besonders nützlich für hereinkommende Daten.

Ohne ein Datenvalidierungssystem müssten Sie alle Prüfungen manuell im Code durchführen.

FastAPI 现在会：

- 对数据进行**校验**，确保最大长度为 50 个字符
- 当数据无效时向客户端展示**清晰的错误**
- 在 OpenAPI 模式的*路径操作*中**记录**该参数（因此会出现在**自动文档 UI** 中）

## 另一种（旧的）方式：把 `Query` 作为默认值 { #alternative-old-query-as-the-default-value }

早期版本的 FastAPI（<dfn title="早于 2023-03">0.95.0</dfn> 之前）要求你把 `Query` 作为参数的默认值，而不是放在 `Annotated` 里。你很可能会在别处看到这种写法，所以我也给你解释一下。

Even so, Go provides a mechanism called GODEBUG to
reduce the impact such changes have on Go developers
using newer toolchains to compile old code.

A GODEBUG setting is a `key=value` pair
that controls the execution of certain parts of a Go program.
The environment variable `GODEBUG`
can hold a comma-separated list of these settings.
For example, if a Go program is running in an environment that contains

       * elements from each bin must either stay at same index, or move with a power of two offset.
       * We eliminate unnecessary node creation by catching cases where old nodes can be reused
       * because their next fields won't change. Statistically, at the default threshold, only
       * about one-sixth of them need cloning when a table doubles. The nodes they replace will be

   * code.
