使用为云存储源创建数据流 Flow Service API

本教程介绍了从云存储源检索数据以及使用 Flow Service API.

快速入门

本教程要求您对Adobe Experience Platform的以下组件有一定的了解：

• Experience Data Model (XDM) System:Experience Platform组织客户体验数据的标准化框架。
  • 架构组合的基础知识:了解XDM模式的基本构建块，包括模式组合中的关键原则和最佳实践。
  • 架构注册开发人员指南:包括成功调用架构注册表API所需了解的重要信息。 这包括您的 {TENANT_ID}、“容器”的概念以及发出请求所需的标头（请特别注意接受标头及其可能值）。
• Catalog Service:目录是Experience Platform中数据位置和谱系的记录系统。
• Batch ingestion:批量摄取API允许您将数据作为批处理文件导入到Experience Platform中。
• 沙箱:Experience Platform提供将单个Platform实例分区为单独虚拟环境的虚拟沙盒，以帮助开发和改进数字体验应用程序。

使用Platform API

有关如何成功调用Platform API的信息，请参阅 Platform API快速入门.

创建源连接

您可以通过向 sourceConnections 端点 Flow Service 提供基本连接ID时的API、要摄取的源文件的路径以及源的相应连接规范ID。

创建源连接时，还必须为数据格式属性定义枚举值。

为基于文件的源使用以下枚举值：

对于所有基于表的源，将值设置为 tabular.

API格式

POST /sourceConnections

请求

curl -X POST \
    'https://platform.adobe.io/data/foundation/flowservice/sourceConnections' \
    -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}' \
    -H 'Content-Type: application/json' \
    -d '{
        "name": "Cloud Storage source connection",
        "description: "Source connection for a cloud storage source",
        "baseConnectionId": "1f164d1b-debe-4b39-b4a9-df767f7d6f7c",
        "data": {
            "format": "delimited",
            "properties": {
                "columnDelimiter": "{COLUMN_DELIMITER}",
                "encoding": "{ENCODING}"
                "compressionType": "{COMPRESSION_TYPE}"
            }
        },
        "params": {
            "path": "/acme/summerCampaign/account.csv",
            "type": "file"
        },
        "connectionSpec": {
            "id": "4c10e202-c428-4796-9208-5f1f5732b1cf",
            "version": "1.0"
        }
    }'

响应

成功的响应会返回唯一标识符(id)。 在后续步骤中需要此ID才能创建数据流。

{
    "id": "26b53912-1005-49f0-b539-12100559f0e2",
    "etag": "\"11004d97-0000-0200-0000-5f3c3b140000\""
}

创建目标XDM架构

要在Platform中使用源数据，必须创建目标架构以根据您的需求构建源数据。 然后，目标架构用于创建包含源数据的Platform数据集。

通过对 架构注册表API.

有关如何创建目标XDM架构的详细步骤，请参阅 使用API创建模式.

创建目标数据集

通过对 目录服务API，在有效负载中提供目标架构的ID。

有关如何创建目标数据集的详细步骤，请参阅 使用API创建数据集.

创建目标连接

目标连接表示所摄取数据所登陆目标的连接。 要创建目标连接，必须提供与数据湖关联的固定连接规范ID。 此连接规范ID为： c604ff05-7f1a-43c0-8e18-33bf874cb11c.

现在，您将唯一标识符作为目标数据集的目标架构，并将连接规范ID用于数据湖。 使用这些标识符，您可以使用 Flow Service 用于指定将包含集客源数据的数据集的API。

API格式

POST /targetConnections

请求

curl -X POST \
    'https://platform.adobe.io/data/foundation/flowservice/targetConnections' \
    -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}' \
    -H 'Content-Type: application/json' \
    -d '{
        "name": "Target Connection for a Cloud Storage connector",
        "description": "Target Connection for a Cloud Storage connector",
        "data": {
            "schema": {

                "version": "application/vnd.adobe.xed-full+json;version=1"
            }
        },
        "params": {
            "dataSetId": "5f3c3cedb2805c194ff0b69a"
        },
            "connectionSpec": {
            "id": "c604ff05-7f1a-43c0-8e18-33bf874cb11c",
            "version": "1.0"
        }
    }'

响应

成功的响应会返回新目标连接的唯一标识符(id)。 此ID是后续步骤所必需的。

{
    "id": "dbc5c132-bc2a-4625-85c1-32bc2a262558",
    "etag": "\"8e000533-0000-0200-0000-5f3c40fd0000\""
}

创建映射

要将源数据摄取到目标数据集，必须先将其映射到目标数据集所附加的目标架构。

要创建映射集，请向 mappingSets 的端点 Data Prep API 提供目标XDM模式时 $id 以及要创建的映射集的详细信息。

API格式

POST /conversion/mappingSets

请求

curl -X POST \
    'https://platform.adobe.io/data/foundation/conversion/mappingSets' \

            {
                "destinationXdmPath": "person.name.lastName",
                "sourceAttribute": "LastName",

                "version": 0
            }
        ]
    }'

响应

成功的响应会返回新创建映射的详细信息，包括其唯一标识符(id)。 在后续步骤中需要此值才能创建数据流。

{
    "id": "bf5286a9c1ad4266baca76ba3adc9366",
    "version": 0,
    "createdDate": 1597784069368,
    "modifiedDate": 1597784069368,
    "createdBy": "{CREATED_BY}",
    "modifiedBy": "{MODIFIED_BY}"
}

检索数据流规范

数据流负责从源中收集数据并将它们引入平台。 要创建数据流，必须首先获取负责收集云存储数据的数据流规范。

创建数据流

收集云存储数据的最后一步是创建数据流。 现在，您已准备以下必需值：

• 源连接ID
• Target连接ID
• 映射ID
• 数据流规范ID

数据流负责从源中调度和收集数据。 通过在有效负载中提供先前提到的值时执行POST请求，可以创建数据流。

要计划摄取，您必须首先将开始时间值设置为以秒为单位的新纪元时间。 然后，您必须将频率值设置为以下五个选项之一： once, minute, hour, day或 week. 间隔值可指定两个连续摄取和创建一次性摄取之间的周期，而无需设置间隔。 对于所有其他频率，间隔值必须设置为等于或大于 15.
