This affects the generated OpenAPI (e.g. visible at `/docs`).

                Read more about it in the
                [FastAPI docs for Query Parameters and String Validations](https://fastapi.tiangolo.com/tutorial/query-params-str-validations/#exclude-from-openapi).

被替换为了以下文本格式的错误信息：

```
1 validation error
path -> item_id
  value is not a valid integer (type=type_error.integer)

### `RequestValidationError` vs `ValidationError`

/// warning | "警告"

如果您觉得现在还用不到以下技术细节，可以先跳过下面的内容。

//     restrictions like, "must refer only to types A and B" or "UID not honored" or "name must be restricted".
//     Those cannot be well described when embedded.
//  3. Inconsistent validation.  Because the usages are different, the validation rules are different by usage, which makes it hard for users to predict what will happen.

               "expr": "sum (rate(galley_validation_failed[$__rate_interval]))",
               "legendFormat": "Failure"
            }
         ],

- Fixed EndpointSlice port name validation to match Endpoint port name validation (allowing port names longer than 15 characters) ([#84481](https://github.com/kubernetes/kubernetes/pull/84481), [@robscott](https://github.com/robscott))

    // getHostAddress on android sometimes maps the scope id to an invalid interface name; if the
    // mapped interface isn't present, fallback to use the scope id (which has no validation against
    // present interfaces)
    NetworkInterface scopedInterface = ip.getScopedInterface();
    if (scopedInterface != null) {
      return "%" + scopedInterface.getName();
    }

Pruning requires that CRD developer provides complete, structural validation schemas, either at the top-level or for all versions of the CRD.

#### CustomResourceDefinition Defaulting

CustomResourceDefinitions also have new support for defaulting, with defaults specified using the `default` keyword in the OpenAPI validation schema. Defaults are set for unspecified fields in an object sent to the API, and when reading from etcd.

## Les modèles Pydantic

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> est une bibliothèque Python pour effectuer de la validation de données.

Vous déclarez la forme de la donnée avec des classes et des attributs.

Chaque attribut possède un type.

	// Total length of the alpha numeric table.
	alphaNumericTableLen = byte(len(alphaNumericTable))

	reservedChars = "=,"
)

// Common errors generated for access and secret key validation.
var (
	ErrInvalidAccessKeyLength   = fmt.Errorf("access key length should be between %d and %d", accessKeyMinLen, accessKeyMaxLen)
