# 批量删除集群标签-BatchDeleteClusterTags #### 功能介绍 为指定MRS集群批量删除标签。一个集群上最多有20个标签。该接口为幂等接口：删除不存在的标签默认处理成功，不对标签字符集范围做校验。 Key长度为128个字符，value为255个字符。删除时tags结构体不能缺失，key不能为空，或者空字符串。 #### 接口约束 无 #### 调用方法 请参见[如何调用API](https://support.huaweicloud.com/api-mrs/zh-cn_topic_0013582897.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-mrs/mrs_02_0221.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}/tags/action 表1路径参数 | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | cluster_id | 是 | String | **参数解释：** 集群ID。获取方法，请参见[获取集群ID](https://support.huaweicloud.com/api-mrs/mrs_02_9001.html#mrs_02_9001__zh-cn_topic_0264280065_section177891315153619)。 **约束限制：** 不涉及 **取值范围：** 只能由英文字母、数字以及"_"和"-"组成，且长度为\[1-64\]个字符。 **默认取值：** 不涉及 | | project_id | 是 | String | **参数解释：** 项目编号。获取方法，请参见[获取项目ID](https://support.huaweicloud.com/api-mrs/mrs_02_0011.html)。 **约束限制：** 不涉及 **取值范围：** 只能由英文字母和数字组成，且长度为\[1-64\]个字符。 **默认取值：** 不涉及 | #### 请求参数 表2请求Body参数 | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | action | 是 | String | **参数解释：** 操作标识：仅限于delete（删除）。 **约束限制：** 不涉及 **取值范围：** - delete：删除标签。 **默认取值：** 不涉及 | | tags | 是 | Array of [Tag] objects | **参数解释：** 标签列表。 **约束限制：** 不涉及 **取值范围：** 不涉及 **默认取值：** 不涉及 | 表3Tag | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | key | 是 | String | **参数解释：** 标签的键。 **约束限制：** 不涉及 **取值范围：** - 最大长度128个字符，不能为空字符串。 - 同一资源的key值不能重复。 - 标签的key值可以包含任意语种字母、数字、空格和_.:=+-@，但首尾不能含有空格，不能以_sys_开头。 **默认取值：** 不涉及 | | value | 是 | String | **参数解释：** 标签的值。 **约束限制：** 不涉及 **取值范围：** - 最大长度255个字符，可以为空字符串。 - 标签的value值可以包含任意语种字母、数字、空格和_.:=+-@，但首尾不能含有空格，不能以_sys_开头。 **默认取值：** 不涉及 | #### 响应参数 **状态码：204** 操作成功。 无 #### 请求示例 批量删除 ``` POST /v1.1/{project_id}/clusters/{cluster_id}/tags/action { "action" : "delete", "tags" : [ { "key" : "DEV1", "value" : "DEV1" }, { "key" : "DEV2", "value" : "DEV2" } ] } ``` #### 响应示例 无 #### SDK代码示例 SDK代码示例如下。 - [Java] 批量删除 ``` 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.mrs.v1.region.MrsRegion; import com.huaweicloud.sdk.mrs.v1.*; import com.huaweicloud.sdk.mrs.v1.model.*; import java.util.List; import java.util.ArrayList; public class BatchDeleteClusterTagsSolution { 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.
