示例二：启动迁移任务

场景描述

本章节指导用户通过API启动迁移任务。API的调用方法请参见如何调用API。

启动迁移任务前需要获取Token，启动迁移任务后，需要查询任务状态详情，失败或暂停中的任务才能被启动。

涉及接口

操作步骤

  1. 获取IAM用户Token。

    • 接口相关信息

      URI格式：POST /v3/auth/tokens

      详情请参见获取IAM用户Token（使用密码）。

    • 请求示例 
      POST: https://{iam_endpoint}/v3/auth/tokens

      {endpoint}信息请从地区和终端节点获取。

      Body： 
      {
    "auth": {
        "identity": {
            "methods": [
                "password"
            ],
            "password": {
                "user": {
                    "name": "testname",
                    "domain": {
                        "name": "testname"
                    },
                    "password": "Password"
                }
            }
        },
        "scope": {
            "project": {
                "id": "0215ef11e49d4743be23dd97a1561xxx"
            }
        }
    }
}

    响应Header中“X-Subject-Token”的值即为Token：

    X-Subject-Token:MIIDkgYJKoZIhvcNAQcCoIIDgzCCA38CAQExDTALBglghkgBZQMEAgEwgXXXXX...

  2. 调用启动任务接口启动迁移任务。

    • 接口相关信息

      URI格式：

      POST /v3/tasks/{task_id}/action

      详情请参见管理迁移任务(启动)。

    • 请求示例 
      POST  https://sms.ap-southeast-1.myhuaweicloud.com/v3/tasks/8abda8635e09d185015e09d188dd0001xx/action

      Header：

      Content-Type: application/json
X-Auth-Token: “Token”

      Body:

      {
        "operation" : "start",
}

      响应200表示调用成功。

  3. 调用查看任务接口，查看任务状态。

    • 接口相关信息

      URI格式：

      GET /v3/tasks/{task_id}

      详情请参见查询指定ID的迁移任务。

    • 请求示例 
      GET  https://sms.ap-southeast-1.myhuaweicloud.com/v3/tasks/8abda8635e09d185015e09d188dd0001xx

      Header：

      Content-Type: application/json
X-Auth-Token: “Token”
