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”
