数据类型端点

数据类型在类或架构字段组中用作引用类型字段，其方式与基本文字字段相同，关键区别在于数据类型可以定义多个子字段。 虽然与中的字段组类似，它们允许一致地使用多字段结构，但数据类型更加灵活，因为它们可以包含在架构结构中的任意位置，而字段组只能在根级别添加。 的 /datatypes 的端点 Schema Registry API允许您以编程方式管理体验应用程序中的数据类型。

快速入门

本指南中使用的端点是 Schema Registry API. 在继续之前，请查看 入门指南 有关相关文档的链接，请参阅本文档中的API调用示例指南，以及有关成功调用任何Experience PlatformAPI所需标头的重要信息。

检索数据类型列表

您可以在 global 或 tenant 容器，方法是向 /global/datatypes 或 /tenant/datatypes，分别为。

API格式

GET /{CONTAINER_ID}/datatypes?{QUERY_PARAMS}

请求

以下请求从 tenant 容器，使用 orderby 查询参数来按数据类型进行排序 title 属性。

curl -X GET \
  https://platform.adobe.io/data/foundation/schemaregistry/tenant/datatypes?orderby=title \
  -H 'Accept: application/vnd.adobe.xed-id+json' \
  -H 'Authorization: Bearer {ACCESS_TOKEN}' \
  -H 'x-api-key: {API_KEY}' \
  -H 'x-gw-ims-org-id: {ORG_ID}' \
  -H 'x-sandbox-name: {SANDBOX_NAME}'

响应格式取决于 Accept 请求中发送的标头。 以下 Accept 标头可用于列出数据类型：

响应

上述请求使用 application/vnd.adobe.xed-id+json Accept 标头，因此响应仅包含 title, $id, meta:altId和 version 属性。 使用其他 Accept 标题(application/vnd.adobe.xed+json)会返回每个数据类型的所有属性。 选择相应的 Accept 标头，具体取决于您在响应中需要的信息。

      "href": "https://platform.adobe.io/data/foundation/schemaregistry/global/datatypes?orderby=title"
    }
  }
}

查找数据类型

您可以通过在GET请求的路径中包含数据类型的ID来查找特定数据类型。

API格式

GET /{CONTAINER_ID}/datatypes/{DATA_TYPE_ID}

请求

以下请求通过 meta:altId 值。

curl -X GET \
  https://platform.adobe.io/data/foundation/schemaregistry/tenant/datatypes/_{TENANT_ID}.datatypes.78570e371092c032260714dd8bfd6d44 \
  -H 'Accept: application/vnd.adobe.xed+json' \
  -H 'Authorization: Bearer {ACCESS_TOKEN}' \
  -H 'x-api-key: {API_KEY}' \
  -H 'x-gw-ims-org-id: {ORG_ID}' \
  -H 'x-sandbox-name: {SANDBOX_NAME}'

响应格式取决于 Accept 请求中发送的标头。 所有查找请求都需要 version 包括在 Accept 标题。 以下 Accept 标头可用：

响应

成功的响应会返回数据类型的详细信息。 返回的字段取决于 Accept 请求中发送的标头。 试验 Accept 标头来比较响应并确定最适合您的用例的标头。

创建数据类型

您可以在 tenant 容器，方法是发出POST请求。

API格式

POST /tenant/datatypes

请求

与字段组不同，定义数据类型不需要 meta:extends 或 meta:intendedToExtend 字段，也无需嵌套字段以避免冲突。

在定义数据类型本身的字段结构时，您可以使用基元类型(例如 string 或 object)或者您可以通过 $ref 属性。 请参阅 在API中定义自定义XDM字段 有关不同XDM字段类型的预期格式的详细指导。

以下请求创建具有子属性的“Property Construction”对象数据类型 yearBuilt, propertyType和 location:

删除数据类型

有时可能需要从架构注册表中删除数据类型。 这是通过使用路径中提供的数据类型ID执行DELETE请求来完成的。

API格式

DELETE /tenant/datatypes/{DATA_TYPE_ID}

请求

curl -X DELETE \
  https://platform.adobe.io/data/foundation/schemaregistry/tenant/datatypes/_{TENANT_ID}.datatypes.d5cc04eb8d50190001287e4c869ebe67 \
  -H 'Authorization: Bearer {ACCESS_TOKEN}' \
  -H 'x-api-key: {API_KEY}' \
  -H 'x-gw-ims-org-id: {ORG_ID}' \
  -H 'x-sandbox-name: {SANDBOX_NAME}'

响应

成功响应会返回HTTP状态204（无内容）和空白正文。

您可以通过尝试 查找(GET)请求 到数据类型。 您需要包含 Accept 标头，但应会收到HTTP状态404（未找到），因为数据类型已从架构注册表中删除。
