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.*;
import com.google.gson.Gson;
import java.util.List;

    }

    /**

    }

    }

    /**

     */
    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

        IAcsClient client = new DefaultAcsClient(profile);

        DeleteRamUserDemo deleteRamUserDemo = new DeleteRamUserDemo();
        // 要删除的RAM用户名
        String userName = "doctest";

        try {
            // 查询出RAM用户加入的所有用户组
            ListGroupsForUserRequest listGroupsForUserRequest = new ListGroupsForUserRequest();
            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);

            }

            // 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:
