本教程详细介绍如何使用Alibaba Cloud SDK for Java删除一个RAM用户。

前提条件

在使用本教程前,请确保已完成以下操作:

  • 使用Alibaba Cloud SDK for Java,您需要一个阿里云账号和访问密钥(AccessKey)。 请在阿里云控制台中的AccessKey管理页面上创建和查看您的AccessKey。
  • 确保您已经安装了Alibaba Cloud SDK for Java,准确的SDK版本号,请参见阿里云开发工具包(SDK)
    <dependencies>     <!-- https://mvnrepository.com/artifact/com.aliyun/aliyun-java-sdk-core --&gt;     <dependency&gt;         <groupId>com.aliyun</groupId>         <artifactId>aliyun-java-sdk-core</artifactId>         <version>4.4.3</version>     </dependency>     <!-- https://mvnrepository.com/artifact/com.aliyun/aliyun-java-sdk-ram -->     <dependency>         <groupId>com.aliyun</groupId>         <artifactId>aliyun-java-sdk-ram</artifactId>         <version>2.0.7</version>     </dependency> </dependencies>

代码示例

本文操作示例主要以代码形式体现,具体代码如下:

import com.aliyuncs.DefaultAcsClient; import com.aliyuncs.IAcsClient; import com.aliyuncs.exceptions.ClientException; import com.aliyuncs.profile.DefaultProfile; import com.aliyuncs.ram.model.v20150501.*;

    }      /**      * 将RAM用户从用户组中移除      */     private RemoveUserFromGroupResponse removeUserFromGroup(RemoveUserFromGroupRequest request, IAcsClient client) throws ClientException {         return client.getAcsResponse(request);     }      /**      * 列出指定用户的权限策略      */     private ListPoliciesForUserResponse listPoliciesForUser(ListPoliciesForUserRequest request, IAcsClient client) throws ClientException {         return client.getAcsResponse(request);     }      /**      * 为用户撤销指定的权限      */     private DetachPolicyFromUserResponse detachPolicyFromUser(DetachPolicyFromUserRequest request,IAcsClient client) throws ClientException {         return client.getAcsResponse(request);     }      /**      * 删除一个RAM用户      */     private DeleteUserResponse deleteUser(DeleteUserRequest request,IAcsClient client) throws ClientException {         return client.getAcsResponse(request);     }      private static void log_print(String functionName, Object result) {         Gson gson = new Gson();         System.out.println("-------------------------------" + functionName + "-------------------------------");         System.out.println(gson.toJson(result));     }      public static void main(String[] args) {         // 设置鉴权参数,初始化客户端         DefaultProfile profile = DefaultProfile.getProfile(                 "cn-qingdao",// 地域ID                 "your-access-key-id",// 您的AccessKey ID                 "your-access-key-secret");// 您的AccessKey Secret         IAcsClient client = new DefaultAcsClient(profile);

            listGroupsForUserRequest.setUserName(userName);             ListGroupsForUserResponse listGroupsForUserResponse = deleteRamUserDemo.listGroupsForUser(listGroupsForUserRequest, client);             log_print("listGroupsForUser",listGroupsForUserResponse);              List<ListGroupsForUserResponse.Group> groups = listGroupsForUserResponse.getGroups();             //遍历用户组,并从用户组中移除该RAM用户             for (ListGroupsForUserResponse.Group group : groups) {                 String groupName = group.getGroupName();                 RemoveUserFromGroupRequest removeUserFromGroupRequest = new RemoveUserFromGroupRequest();                 removeUserFromGroupRequest.setUserName(userName);                 removeUserFromGroupRequest.setGroupName(groupName);                 RemoveUserFromGroupResponse removeUserFromGroupResponse = deleteRamUserDemo.removeUserFromGroup(removeUserFromGroupRequest, client);                 log_print("removeUserFromGroup",removeUserFromGroupResponse);             }              // 查询出用户的所有权限策略             ListPoliciesForUserRequest listPoliciesForUserRequest = new ListPoliciesForUserRequest();             listPoliciesForUserRequest.setUserName(userName);             ListPoliciesForUserResponse listPoliciesForUserResponse = deleteRamUserDemo.listPoliciesForUser(listPoliciesForUserRequest, client);             log_print("listPoliciesForUser",listPoliciesForUserResponse);              List<ListPoliciesForUserResponse.Policy> policies = listPoliciesForUserResponse.getPolicies();             // 遍历权限策略并撤销授权             for (ListPoliciesForUserResponse.Policy policy : policies) {                 // 权限名称                 String policyName = policy.getPolicyName();                 // 权限类型                 String policyType = policy.getPolicyType();                 DetachPolicyFromUserRequest detachPolicyFromUserRequest = new DetachPolicyFromUserRequest();                 detachPolicyFromUserRequest.setUserName(userName);                 detachPolicyFromUserRequest.setPolicyType(policyType);                 detachPolicyFromUserRequest.setPolicyName(policyName);                 DetachPolicyFromUserResponse detachPolicyFromUserResponse = deleteRamUserDemo.detachPolicyFromUser(detachPolicyFromUserRequest, client);                 log_print("detachPolicyFromUser",detachPolicyFromUserResponse);             }              // 删除RAM用户             DeleteUserRequest deleteUserRequest = new DeleteUserRequest();             deleteUserRequest.setUserName(userName);             DeleteUserResponse deleteUserResponse = deleteRamUserDemo.deleteUser(deleteUserRequest, client);             log_print("deleteUser",deleteUserResponse);         } catch (ClientException e) {             e.printStackTrace();         }      } }

运行结果

正确的执行结果类似如下:

-------------------------------listGroupsForUser------------------------------- {     "requestId": "24BF3B77-3B50-48BA-94C4-E10545842C37",     "groups": [         {             "groupName": "testgroupofqwj",             "comments": "",             "joinDate": "2019-10-11T01:11:03Z"         }     ] } -------------------------------removeUserFromGroup------------------------------- {     "requestId": "E6564998-277B-4252-8736-D50A8BCBB8BC" } -------------------------------listPoliciesForUser------------------------------- {     "requestId": "FBF4184D-29FB-4C83-B897-234C2A2137F0",     "policies": [         {             "policyName": "AdministratorAccess",             "policyType": "System",             "description": "管理所有阿里云资源的权限",             "defaultVersion": "v1",             "attachDate": "2019-10-10T08:54:19Z"         }     ] } -------------------------------detachPolicyFromUser------------------------------- {     "requestId": "1E851642-DC59-4AA6-A31A-82E28F35605B" } -------------------------------deleteUser------------------------------- {     "requestId": "F86ACE15-6537-4147-B500-E5F284D4A6BA" }
