本教程详细介绍如何使用Alibaba Cloud SDK for Java查询RAM账号详情、权限、用户组及所属云账号信息。

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)

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;

/**
 * 查询RAM账号信息
 */
public class DescribeRamUserDemo {

    /**
     * 获取用户的详细信息
     */
    private GetUserResponse getUser(GetUserRequest 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);
    }

    /**
     * 查看云账号别名
     */
    private GetAccountAliasResponse getAccountAlias(GetAccountAliasRequest request,IAcsClient client) throws ClientException {
        return client.getAcsResponse(request);
    }

    /**
     * 列出指定RAM用户所加入的用户组信息
     */
    private ListGroupsForUserResponse listGroupsForUser(ListGroupsForUserRequest request,IAcsClient client) throws ClientException {
        return client.getAcsResponse(request);
    }

    /**
     * 获取用户组信息
     */
    private GetGroupResponse getGroup(GetGroupRequest 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);

        DescribeRamUserDemo describeRamUserDemo = new DescribeRamUserDemo();

        try {
            // 查询用户详情
            GetUserRequest getUserRequest = new GetUserRequest();
            getUserRequest.setUserName("doctest");
            GetUserResponse getUserResponse = describeRamUserDemo.getUser(getUserRequest, client);
            log_print("getUser",getUserResponse);

            // 查询用户的权限策略
            ListPoliciesForUserRequest listPoliciesForUserRequest = new ListPoliciesForUserRequest();
            listPoliciesForUserRequest.setUserName("doctest");
            ListPoliciesForUserResponse listPoliciesForUserResponse = describeRamUserDemo.listPoliciesForUser(listPoliciesForUserRequest, client);
            log_print("listPoliciesForUser",listPoliciesForUserResponse);

            // 查询云账号别名
            GetAccountAliasRequest getAccountAliasRequest = new GetAccountAliasRequest();
            GetAccountAliasResponse accountAlias = describeRamUserDemo.getAccountAlias(getAccountAliasRequest, client);
            log_print("getAccountAlias",accountAlias);

            // 查询用户加入的用户组
            ListGroupsForUserRequest listGroupsForUserRequest = new ListGroupsForUserRequest();
            listGroupsForUserRequest.setUserName("doctest");
            ListGroupsForUserResponse listGroupsForUserResponse = describeRamUserDemo.listGroupsForUser(listGroupsForUserRequest, client);
            log_print("listGroupsForUser",listGroupsForUserResponse);

            List<ListGroupsForUserResponse.Group> groups = listGroupsForUserResponse.getGroups();
            // 遍历查询用户加入的所有用户组信息
            for (ListGroupsForUserResponse.Group group : groups) {
                // 获取用户组名称
                String groupName = group.getGroupName();
                GetGroupRequest getGroupRequest = new GetGroupRequest();
                getGroupRequest.setGroupName(groupName);
                GetGroupResponse getGroupResponse = describeRamUserDemo.getGroup(getGroupRequest, client);
                log_print("getGroup",getGroupResponse);
            }
        } catch (ClientException e) {
            e.printStackTrace();
        }
    }
}
