# 启动集群 - StartCluster #### 功能介绍 启动集群接口。 #### 调用方法 请参见[如何调用API](https://support.huaweicloud.com/api-dataartsstudio/making_request.html)。 #### 授权信息 账号具备所有API的调用权限，如果使用账号下的IAM用户调用当前API，该IAM用户需具备调用API所需的权限。 - 如果使用角色与策略授权，具体权限要求请参见[权限和授权项](https://support.huaweicloud.com/api-dataartsstudio/abcd.html)。 - 如果使用身份策略授权，当前API调用无需身份策略权限。 #### URI POST /v1.1/{project_id}/clusters/{cluster_id}/action 表1路径参数 | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | project_id | 是 | String | 项目ID，获取方法请参见[项目ID和账号ID](https://support.huaweicloud.com/api-dataartsstudio/projectid_accountid.html)。 | | cluster_id | 是 | String | 集群ID，获取方法请参见[获取集群列表](https://support.huaweicloud.com/api-dataartsstudio/ListClusters.html)。 | #### 请求参数 表2请求Header参数 | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | X-Auth-Token | 是 | String | 用户Token，使用[Token认证](https://support.huaweicloud.com/api-dataartsstudio/dataartsstudio_02_0010.html)时必选。通过调用IAM服务的"获取用户Token"接口获取响应消息头中X-Subject-Token的值。 | 表3请求Body参数 | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | start | 是 | Object | 集群启动操作，定义集群启动标识，为空对象。 | #### 响应参数 **状态码：200** 表4响应Body参数 | 参数 | 参数类型 | 描述 | |:---|:---|:---| | jobId | Array of strings | 作业ID。 | #### 请求示例 启动集群。 ``` POST /v1.1/1551c7f6c808414d8e9f3c514a170f2e/clusters/bae65496-643e-47ca-84af-948672de7eeb/action { "start" : { } } ``` #### 响应示例 **状态码：200** OK。 ``` { "jobId" : [ "ff8080815e59d92d015e5b27ccb0004d" ] } ``` #### SDK代码示例 SDK代码示例如下。 - [Java] 启动集群。 ``` package com.huaweicloud.sdk.test; import com.huaweicloud.sdk.core.auth.ICredential; import com.huaweicloud.sdk.core.auth.BasicCredentials; import com.huaweicloud.sdk.core.exception.ConnectionException; import com.huaweicloud.sdk.core.exception.RequestTimeoutException; import com.huaweicloud.sdk.core.exception.ServiceResponseException; import com.huaweicloud.sdk.cdm.v1.region.CdmRegion; import com.huaweicloud.sdk.cdm.v1.*; import com.huaweicloud.sdk.cdm.v1.model.*; public class StartClusterSolution { public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great security risks.
