Question

有没有办法获取aws的弹性网络接口的MAC地址，使用aws JAVA SDk

Answer 1

我可以使用describe-network-interfaces命令使用AWS-CLI获取MAC地址，如下所示：

$ aws ec2 describe-network-interfaces --network-interface-ids eni-eaxxxxd | jq ".NetworkInterfaces[].MacAddress"
"06:56:88:b9:82:17"

同样在Ruby-SDK中，有一种方法可以使用describe_network_interfaces-instance_method

来提取MAC地址

我搜索了DescribeNetworkInterfacesRequest的JAVA SDK文档，似乎确实提供了mac地址。但是，我不擅长阅读JAVA API文档。

由于我能够使用AWS-CLI和RUBY-SDK获取MAC地址，因此API已就绪。只需要在JAVA-SDK文档中获取确切的方法。

// get network interface of instance and from that get mac address
                List<InstanceNetworkInterface> networkInterfaces = inst.getNetworkInterfaces();
                for (InstanceNetworkInterface instanceNetworkInterface : networkInterfaces) {
                    System.out.println("=-------------"+instanceNetworkInterface.getNetworkInterfaceId());


                    DescribeNetworkInterfacesRequest describeNetworkInterfacesRequest = new DescribeNetworkInterfacesRequest();
                    describeNetworkInterfacesRequest.withNetworkInterfaceIds(instanceNetworkInterface.getNetworkInterfaceId());
                    DescribeNetworkInterfacesResult describeNetworkInterfacesResult = amazonEc2.describeNetworkInterfaces(describeNetworkInterfacesRequest);
                    List<NetworkInterface> networkInterfaces1 = describeNetworkInterfacesResult.getNetworkInterfaces();
                    for (NetworkInterface networkInterface : networkInterfaces1) {
                        System.out.println(networkInterface.getMacAddress());

                    }
                }
