数据类型端点

数据类型在类或混合中用作引用类型字段的方式与基本文本字段相同，关键区别在于数据类型可以定义多个子字段。虽然与混音类似，它们允许多字段结构的一致使用，但数据类型更灵活，因为它们可以包含在模式结构中的任何位置，而混音只能添加在根级别。 Schema Registry API中的/datatypes端点允许您以编程方式管理体验应用程序中的数据类型。

入门指南

本指南中使用的端点是Schema Registry API的一部分。在继续之前，请查看入门指南，了解相关文档的链接、阅读此文档中示例API调用的指南，以及成功调用任何Experience PlatformAPI所需的重要头信息。

检索列表数据类型

您可以通过分别向/global/datatypes或/tenant/datatypes发出列表请求，来GETglobal或tenant容器下的所有数据类型。

注意

列出资源时，模式注册表将结果集限制为300项。要返回超出此限制的资源，必须使用分页参数。还建议您使用其他查询参数来筛选结果并减少返回的资源数。有关详细信息，请参见附录文档中的查询参数一节。

API格式

GET /{CONTAINER_ID}/datatypes?{QUERY_PARAMS}

参数	描述
`{CONTAINER_ID}`	要从以下位置检索数据类型的容器:`global`用于Adobe创建的数据类型，或`tenant`用于您的组织拥有的数据类型。
`{QUERY_PARAMS}`	可选查询参数，用于筛选结果。有关可用参数的列表，请参见附录文档。

请求

以下请求从tenant列表检索数据类型容器，使用orderby查询参数按数据类型的title属性对数据类型进行排序。

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: {IMS_ORG}' \
  -H 'x-sandbox-name: {SANDBOX_NAME}'

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

`Accept` 标题	描述
`application/vnd.adobe.xed-id+json`	返回每个资源的简短摘要。这是列出资源的建议标头。 (限制：300)
`application/vnd.adobe.xed+json`	为每个资源返回完整的JSON数据类型，其中包括原始`$ref`和`allOf`。 (限制：300)

响应

上述请求使用application/vnd.adobe.xed-id+json Accept头，因此响应仅包括每个数据类型的title、$id、meta:altId和version属性。使用其他Accept标题(application/vnd.adobe.xed+json)可返回每个数据类型的所有属性。根据您在响应中需要的信息，选择相应的Accept头。

    }
  }
}

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}

参数	描述
`{CONTAINER_ID}`	存放要检索的数据类型的容器:`global`表示Adobe创建的数据类型，或`tenant`表示您的组织拥有的数据类型。
`{DATA_TYPE_ID}`	要查找的数据类型的`meta:altId`或URL编码的`$id`。

请求

以下请求按路径中提供的meta:altId值检索数据类型。

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: {IMS_ORG}' \
  -H 'x-sandbox-name: {SANDBOX_NAME}'

响应格式取决于请求中发送的Accept头。所有查找请求都要求version包含在Accept标头中。以下Accept标头可用：

`Accept` 标题	描述
`application/vnd.adobe.xed+json; version={MAJOR_VERSION}`	具有`$ref`和`allOf`的原始数据具有标题和说明。
`application/vnd.adobe.xed-full+json; version={MAJOR_VERSION}`	`$ref` 并 `allOf` 且有标题和说明。
`application/vnd.adobe.xed-notext+json; version={MAJOR_VERSION}`	没有标题或说明的原始数据，具有`$ref`和`allOf`。
`application/vnd.adobe.xed-full-notext+json; version={MAJOR_VERSION}`	`$ref` 并解 `allOf` 析，无标题或说明。
`application/vnd.adobe.xed-full-desc+json; version={MAJOR_VERSION}`	`$ref` 和包 `allOf` 含的描述符。

响应

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

创建数据类型

您可以通过发出容器请求，在tenantPOST下定义自定义数据类型。

API格式

POST /tenant/datatypes

请求

定义数据类型不需要meta:extends或meta:intendedToExtend字段，也不需要嵌套字段以避免冲突。

执行对的GET请求，列表租户容器中的所有数据类型现在都将包括属性详细信息数据类型，或者，您可以使用URL编码的$id URI执行查找(GET)请求以直接视图新数据类型。

更新数据类型

您可以通过PUT操作替换整个数据类型，实质上是重写资源。当通过PUT请求更新数据类型时，主体必须包括在POST请求中创建新数据类型](#create)时所需的所有字段。[

注意

如果您只想更新数据类型的一部分而不是完全替换它，请参阅更新数据类型的部分。

API格式

PUT /tenant/datatypes/{DATA_TYPE_ID}

参数	描述
`{DATA_TYPE_ID}`	要重写的数据类型的`meta:altId`或URL编码的`$id`。

更新数据类型的一部分

您可以使用PATCH请求更新数据类型的一部分。 Schema Registry支持所有标准JSON修补程序操作，包括add、remove和replace。有关JSON修补程序的详细信息，请参阅API基础指南。

注意

如果要用新值替换整个资源，而不是更新单个字段，请参阅中的使用PUT操作替换数据类型一节。

API格式

PATCH /tenant/data type/{DATA_TYPE_ID}

参数	描述
`{DATA_TYPE_ID}`	要更新的数据类型的URL编码的`$id` URI或`meta:altId`。

请求

下面的示例请求更新现有数据类型的description，并添加新的floorSize字段。

请求主体采用数组的形式，每个列出的对象代表对单个字段的特定更改。每个对象都包括要执行的操作(op)，应在(path)上执行该操作的字段，以及该操作应包括哪些信息(value)。

删除数据类型

有时可能需要从模式注册表中删除数据类型。这是通过使用路径中提供的DELETE类型ID执行数据请求来完成的。

API格式

DELETE /tenant/datatypes/{DATA_TYPE_ID}

参数	描述
`{DATA_TYPE_ID}`	要删除的数据类型的URL编码的`$id` URI或`meta:altId`。

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: {IMS_ORG}' \
  -H 'x-sandbox-name: {SANDBOX_NAME}'

响应

成功的响应返回HTTP状态204（无内容）和空白正文。

可以尝试对数据类型查找(GET)请求来确认删除。您需要在请求中包含Accept头，但应接收HTTP状态404（找不到），因为模式注册表中已删除数据类型。
