### Internal

* ✅ Update internal tests for latest Pydantic, including CI tweaks to install the latest Pydantic. PR [#12147](https://github.com/fastapi/fastapi/pull/12147) by [@tiangolo](https://github.com/tiangolo).

## 0.113.0

Now you can declare form fields with Pydantic models:

If you are planning to use digital signature algorithms like RSA or ECDSA, you should install the cryptography library dependency `pyjwt[crypto]`.

You can read more about it in the <a href="https://pyjwt.readthedocs.io/en/latest/installation.html" class="external-link" target="_blank">PyJWT Installation docs</a>.

/// tip

Pydantic 是 FastAPI 中所有数据验证和序列化的核心，当你在没有设默认值的情况下使用 `Optional` 或 `Union[Something, None]` 时，它具有特殊行为，你可以在 Pydantic 文档中阅读有关<a href="https://docs.pydantic.dev/latest/concepts/models/#required-optional-fields" class="external-link" target="_blank">必需可选字段</a>的更多信息。

///

### 使用Pydantic中的`Required`代替省略号(`...`)

如果你觉得使用 `...` 不舒服，你也可以从 Pydantic 导入并使用 `Required`：

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info | "说明"

如果您打算使用类似 RSA 或 ECDSA 的数字签名算法，您应该安装加密库依赖项 `pyjwt[crypto]`。

## 密码哈希

**哈希**是指把特定内容（本例中为密码）转换为乱码形式的字节序列（其实就是字符串）。

每次传入完全相同的内容时（比如，完全相同的密码），返回的都是完全相同的乱码。

	subsysMetrics[key] = metric

	resourceMetricsMap[subSys] = subsysMetrics
}

// updateDriveIOStats - Updates the drive IO stats by calculating the difference between the current and latest updated values.
func updateDriveIOStats(currentStats madmin.DiskIOStats, latestStats madmin.DiskIOStats, labels map[string]string) {
	sectorSize := uint64(512)
	kib := float64(1 << 10)

                            },
                            {
                              "tag": "istio.canonical_revision",
                              "literal": {
                                "value": "latest"
                              }
                            },
                            {

## 구니콘과 유비콘 워커

**Gunicorn**은 **WSGI 표준**을 주로 사용하는 애플리케이션 서버입니다. 이것은 구니콘이 플라스크와 쟝고와 같은 애플리케이션을 제공할 수 있다는 것을 의미합니다. 구니콘 자체는 최신 **<a href="https://asgi.readthedocs.io/en/latest/" class="external-link" target="_blank">ASGI 표준</a>**을 사용하기 때문에 FastAPI와 호환되지 않습니다.

하지만 구니콘은 **프로세스 관리자**역할을 하고 사용자에게 특정 **워커 프로세스 클래스**를 알려줍니다. 그런 다음 구니콘은 해당 클래스를 사용하여 하나 이상의 **워커 프로세스**를 시작합니다.
