数据资产 (Azure 数据目录 REST API)

Annotate

对资产进行注释。

etag 属性是可选的,用于并发控制。

POST https://api.azuredatacatalog.com/catalogs/{catalog_name}/views/{view_name}/{view_item_id}/{nested_view_name}?api-version={api-version}

注意

某些 HTTP 客户端实现可能会自动重新发出请求以响应来自服务器的 302,但通常会从请求中删除 Authorization 标头 。 由于向 ADC 发出请求需要授权标头,因此必须确保在向 ADC 指定的重定向位置重新发出请求时仍提供授权标头。 下面是使用 .NET HttpWebRequest 对象演示这一点的示例代码。

URI 参数

名称 说明 数据类型
catalog_name 目录的名称,或“DefaultCatalog”以使用默认目录。 字符串
view_name 数据资产视图的名称。 字符串
view_item_id 视图项的 ID。 字符串
nested_view_name 嵌套视图项的名称。 字符串
api-version API 版本。 字符串

使用批注获取

获取具有批注的数据资产。

它支持可选的 Accept 标头参数,该参数 adc.metadata 请求在所有项的响应中包括 ETag。 使用最小值或完整值获取 ETag 作为响应。 有效值是 noneminimalfull

请求

GET https://api.azuredatacatalog.com/catalogs/{catalog_name}/views/{view_name}/{view_item_id}?api-version={api-version}  

注意

某些 HTTP 客户端实现可能会自动重新发出请求以响应来自服务器的 302,但通常会从请求中删除 Authorization 标头 。 由于向 ADC 发出请求需要授权标头,因此必须确保在向 ADC 指定的重定向位置重新发出请求时仍提供授权标头。 下面是使用 .NET HttpWebRequest 对象演示这一点的示例代码。

查询参数

名称 说明 数据类型
searchTerms 必需。 要搜索的字词。 字符串
方面 可选 用于对结果进行分面的逗号分隔字段名称。 字符串
startPage 用于分页的结果的可选起始页以及 count 参数。 允许的值大于 0,如果传递的值小于或等于 0,则返回错误代码为 400 的 HTTP 错误。 字符串
count (分页) 单页所需的可选结果数。 默认值为 10。 允许的值的间隔为 1 到 100(含)。 如果传递了此范围外的值,则返回错误代码为 400 的 HTTP 错误。 若要获取搜索结果的下一部分,请重复请求,但将 startPage 增加 1。 Integer
查看 可选 获取客户端要查看的视图,目前是 DataSource 中唯一受支持的选项。 字符串
