# Kafka实例批量删除Topic - BatchDeleteInstanceTopic #### 功能介绍 该接口用于向Kafka实例批量删除Topic。批量删除多个Topic时，部分删除成功，部分失败，此时接口返回删除成功，并在返回中显示删除失败的Topic信息。 #### 调用方法 请参见[如何调用API](https://support.huaweicloud.com/api-kafka/api-call-process.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-kafka/api-grant-policy.html)。 - 如果使用身份策略授权，需具备如下身份策略权限。 | 授权项 | 访问级别 | 资源类型（\*为必须） | 条件键 | 别名 | 依赖的授权项 | |:---|:---|:---|:---|:---|:---| | dms:topic:delete | Write | kafka | - g:ResourceTag/\ - g:EnterpriseProjectId | dms:instance:modify | - | | dms:topic:delete | Write | topic \* | - | dms:instance:modify | - | #### URI POST /v2/{project_id}/instances/{instance_id}/topics/delete 表1路径参数 | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | project_id | 是 | String | **参数解释**： 项目ID，获取方式请参见[获取项目ID](https://support.huaweicloud.com/api-kafka/kafka-api-0036212547.html)。 **约束限制**： 不涉及。 **取值范围**： 不涉及。 **默认取值**： 不涉及。 | | instance_id | 是 | String | **参数解释**： 实例ID。获取方法如下：调用"查询所有实例列表"接口，从响应体中获取实例ID。 **约束限制**： 不涉及。 **取值范围**： 不涉及。 **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 | |:---|:---|:---|:---| | topics | 否 | Array of strings | **参数解释**： 待删除的Topic列表。 **约束限制**： 不涉及。 | #### 响应参数 **状态码：200** 表3响应Body参数 | 参数 | 参数类型 | 描述 | |:---|:---|:---| | topics | Array of [topics] objects | **参数解释**： Topic列表。 | 表4topics | 参数 | 参数类型 | 描述 | |:---|:---|:---| | id | String | **参数解释**： Topic名称。 **取值范围**： 不涉及。 | | success | Boolean | **参数解释**： 是否删除成功。 **取值范围**： - true：删除成功。 - false：删除失败。 | #### 请求示例 批量删除Topic。 ``` POST https://{endpoint}/v2/{project_id}/instances/{instance_id}/topics/delete { "topics" : [ "topic01" ] } ``` #### 响应示例 **状态码：200** 删除成功。 ``` { "topics" : [ { "id" : "topic01", "success" : true } ] } ``` #### SDK代码示例 SDK代码示例如下。 - [Java] 批量删除Topic。 ``` 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.kafka.v2.region.KafkaRegion; import com.huaweicloud.sdk.kafka.v2.*; import com.huaweicloud.sdk.kafka.v2.model.*; import java.util.List; import java.util.ArrayList; public class BatchDeleteInstanceTopicSolution { 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.
