API接入
最近更新时间:2023.12.19 19:07:27首次发布时间:2023.08.30 16:17:17
一、简介

火山引擎DataSail提供数据上报API,用户在开通DataSail服务之后,可以通过API将数据上报到火山云DataSail。

二、前置准备

服务开通

请确保您已开通了您需要访问的服务。您可前往火山引擎控制台开通全域数据集成服务,详见服务开通

获取安全凭证

Access Key(访问密钥)是访问火山引擎服务的安全凭证,包含Access Key ID(简称为AK)和Secret Access Key(简称为SK)两部分。您可登录火山引擎控制台,前往访问控制访问密钥 中创建及管理您的Access Key。更多信息可参考访问密钥帮助文档

产品接入

  1. 申请Topic

路径:数据采集-topic管理-新建Topic

  1. 申请数据采集

路径:数据采集-采集管理-新建采集任务

三、API接入

所需信息汇总

字段说明示例备注

SK火山引擎Secret KeyTW1KaVl******

采集任务ID

采集任务ID

hkktppvwtuv0xy000

获取路径:数据采集->采集管理->采集任务 ID 🔗

服务域名上报数据的域名datasail01-cn-beijing.volceapplog.com
Region区域cn-north-1固定值
Service服务dataleap固定值

服务域名

地域服务域名
华北2(北京)datasail01-cn-beijing.volceapplog.com

服务URL

当上报数据时,需要根据服务域名及采集任务名称组合出最终URL访问地址,格式如下:

https://{服务域名}/v1/production/general/collect/{采集任务ID}/list

例如,采集任务ID为hkktppvwtuv0xy000, 所在地域为华北2(北京),则对应访问地址为:

https://datasail01-cn-beijing.volceapplog.com/v1/production/general/collect/hkktppvwtuv0xy000/list

请求

参数名类型是否必填含义取值逻辑
AuthenticationString火山TOP网关鉴权按火山签名方案后的值

Content-Type

String

上报的数据类型

  • application/json

    • Json格式数据上报,支持批量上报
      • Http header中添加X-Collect-Content-Type: batch_json时,上报批量json数据

      • 无X-Collect-Content-Type时单条json数据上报

  • application/octet-stream

    • 任意类型数据上报
  • 未填

    • 任意类型

请求签名

签名方案参考火山引擎签名: https://www.volcengine.com/docs/6369/67269,可以使用火山引擎已提供的签名SDK: https://www.volcengine.com/docs/6369/156029
整体流程:
alt
因整体签名过程较繁琐,推荐使用火山引擎已封装的SDK,签名与数据上报Demo见下方"接入Demo"。
