# 模式的额外信息 - 例子

您可以在JSON模式中定义额外的信息。

一个常见的用例是添加一个将在文档中显示的`example`。

有几种方法可以声明额外的 JSON 模式信息。

## Pydantic `schema_extra`

您可以使用 `Config` 和 `schema_extra` 为Pydantic模型声明一个示例，如<a href="https://docs.pydantic.dev/latest/concepts/json_schema/#schema-customization" class="external-link" target="_blank">Pydantic 文档：定制 Schema </a>中所述:

//// tab | Python 3.10+

```Python hl_lines="13-21"
{!> ../../docs_src/schema_extra_example/tutorial001_py310.py!}

  optional StorageVersionStatus status = 3;
}

// Describes the state of the storageVersion at a certain point.
message StorageVersionCondition {
  // Type of the condition.
  // +required
  optional string type = 1;

  // Status of the condition, one of True, False, Unknown.
  // +required
  optional string status = 2;

Bucket events can be published to the following targets:

| Supported Notification Targets    |                             |                                 |

func (r *Reader) SetExpectedMax(expectedMax int64) {
	r.expectedMax = expectedMax
}

// AddChecksum will add checksum checks as specified in
// https://docs.aws.amazon.com/AmazonS3/latest/userguide/checking-object-integrity.html
// Returns ErrInvalidChecksum if a problem with the checksum is found.
func (r *Reader) AddChecksum(req *http.Request, ignoreValue bool) error {
	cs, err := GetContentChecksum(req.Header)

		Bucket:           bucket,
		Name:             object,
		ParityBlocks:     fi.Erasure.ParityBlocks,
		DataBlocks:       fi.Erasure.DataBlocks,
		VersionID:        versionID,
		IsLatest:         fi.IsLatest,
		DeleteMarker:     fi.Deleted,
		Size:             fi.Size,
		ModTime:          fi.ModTime,
		Legacy:           fi.XLV1,
		ContentType:      fi.Metadata["content-type"],

## Pydantic `Settings`

Por sorte, o Pydantic possui uma funcionalidade para lidar com essas configurações vindas de variáveis de ambiente utilizando <a href="https://docs.pydantic.dev/latest/usage/pydantic_settings/" class="external-link" target="_blank">Pydantic: Settings management</a>.

### Instalando `pydantic-settings`

Primeiro, instale o pacote `pydantic-settings`:

<div class="termy">

		Message string `xml:"Message"`
	} `xml:"Error"`
	RequestID string `xml:"RequestId"`
}

// STSErrorCode type of error status.
type STSErrorCode int

//go:generate stringer -type=STSErrorCode -trimprefix=Err $GOFILE

// Error codes, non exhaustive list - http://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRoleWithSAML.html
const (
	ErrSTSNone STSErrorCode = iota
	ErrSTSAccessDenied
	ErrSTSMissingParameter

			CipherSuites:             fips.TLSCiphersBackwardCompatible(),
			CurvePreferences:         fips.TLSCurveIDs(),
		}
		// This is only to support client side certificate authentication
		// https://coreos.com/etcd/docs/latest/op-guide/security.html
		etcdClientCertFile := env.Get(EnvEtcdClientCert, kvs.Get(ClientCert))
		etcdClientCertKey := env.Get(EnvEtcdClientCertKey, kvs.Get(ClientCertKey))
		if etcdClientCertFile != "" && etcdClientCertKey != "" {

//
// Instead, we traverse the procfs. Comments on this method are inline.
func getPodNetNs(pod *corev1.Pod) (string, error) {
	parsedPodAddr := net.ParseIP(pod.Status.PodIP)
	if parsedPodAddr == nil {
		return "", fmt.Errorf("failed to parse addr: %s", pod.Status.PodIP)
	}

	fs, err := procfs.NewFS("/host/proc")
	if err != nil {
		return "", fmt.Errorf("read procfs: %v", err)
	}
	procs, err := fs.AllProcs()
