如何修改指定EIP的带宽峰值_阿里云SDK-阿里云帮助中心

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.exceptions.ServerException;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.vpc.model.v20160428.DescribeEipAddressesRequest;
import com.aliyuncs.vpc.model.v20160428.DescribeEipAddressesResponse;
import com.aliyuncs.vpc.model.v20160428.ModifyEipAddressAttributeRequest;
import com.aliyuncs.vpc.model.v20160428.ModifyEipAddressAttributeResponse;
import com.google.gson.Gson;

/**
 * ModifyEipAddressAttribute     修改指定EIP的带宽峰值
 * DescribeEipAddresses     查询指定地域已创建的EIP信息
 */
public class Demo {

    private static String eipId = "eip-uf6****";

    public static void main(String[] args) {
        // 初始化公公共请求参数
        IAcsClient client = initialization();
        // 更改共享带宽的带宽峰值
        ModifyEipAddressAttribute(client,eipId);
        // 查询指定EIP信息
        describeEipAddresses(client,eipId);
    }

    /**
     * DescribeEipAddresses     查询指定地域已创建的EIP信息
     */
    private static void describeEipAddresses(IAcsClient client, String eipId) {
        DescribeEipAddressesRequest request = new DescribeEipAddressesRequest();
        // EIP的ID。
        request.setAllocationId(eipId);
        try {
            DescribeEipAddressesResponse response = client.getAcsResponse(request);
            System.out.println("------------------describeEipAddresses-------------------");
            System.out.println(new Gson().toJson(response));
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            System.out.println("ErrCode:" + e.getErrCode());
            System.out.println("ErrMsg:" + e.getErrMsg());
            System.out.println("RequestId:" + e.getRequestId());
            throw new RuntimeException(e);
        }
    }

    /**
     * ModifyEipAddressAttribute     修改指定EIP的带宽峰值
     */
    private static void ModifyEipAddressAttribute(IAcsClient client, String eipId) {
        ModifyEipAddressAttributeRequest request = new ModifyEipAddressAttributeRequest();
        // EIP的带宽峰值，单位为Mbps。
        request.setBandwidth("100");
        // 弹性公网IP的ID。
        request.setAllocationId(eipId);
        try {
            ModifyEipAddressAttributeResponse response = client.getAcsResponse(request);
            System.out.println("------------------ModifyEipAddressAttribute-------------------");
            System.out.println(new Gson().toJson(response));
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            System.out.println("ErrCode:" + e.getErrCode());
            System.out.println("ErrMsg:" + e.getErrMsg());
            System.out.println("RequestId:" + e.getRequestId());
            throw new RuntimeException(e);
        }
    }

    /**
     * Initialization  初始化公共请求参数
     */
    private static IAcsClient initialization() {
        // 初始化请求参数
        DefaultProfile profile = DefaultProfile.getProfile(
                "<your-region-id>", // 您的可用区ID
                "<your-access-key-id>", // 您的AccessKey ID
                "<your-access-key-secret>"); // 您的AccessKey Secret
        return new DefaultAcsClient(profile);
    }
}

执行结果

正确的执行结果类似如下：

------------------ModifyEipAddressAttribute-------------------
{"requestId":"B7814D2F-2978-47BA-A057-52A50EFF8D4E"}
------------------describeEipAddresses-------------------
