1. 接口描述
接口请求域名： ckafka.tencentcloudapi.com 。
查询Datahub任务信息
默认接口请求频率限制：20次/秒。
推荐使用 API Explorer
点击调试
API Explorer 提供了在线调用、签名验证、SDK 代码生成和快速检索接口等能力。您可查看每次调用的请求内容和返回结果以及自动生成 SDK 调用示例。
2. 输入参数
以下请求参数列表仅列出了接口请求参数和部分公共参数，完整公共参数列表见 公共请求参数。
| 参数名称 | 必选 | 类型 | 描述 |
|---|---|---|---|
| Action | 是 | String | 公共参数，本接口取值：DescribeDatahubTask。 |
| Version | 是 | String | 公共参数，本接口取值：2019-08-19。 |
| Region | 是 | String | 公共参数，详见产品支持的 地域列表。 |
| TaskId | 是 | String | 任务id 示例值：xxx |
3. 输出参数
| 参数名称 | 类型 | 描述 |
|---|---|---|
| Result | DescribeDatahubTaskRes | 返回结果 示例值：xxx |
| RequestId | String | 唯一请求 ID，由服务端生成，每次请求都会返回（若请求因其他原因未能抵达服务端，则该次请求不会获得 RequestId）。定位问题时需要提供该次请求的 RequestId。 |
