amazon-web-services - 如何索引aws快照输出？

Question

我正在打印我的快照。我在下面发布了我希望快照打印出来的样子，并且还希望能够打印单个快照。我不确定该怎么做任何帮助都会很棒。

svc := ec2.New(&aws.Config{Region: "us-east-1"})
params := &ec2.DescribeSnapshotsInput{
    OwnerIDs: []*string{
        aws.String("130300684064"),
    },
}

b, err2 := svc.DescribeSnapshots(params)
if err2 != nil {
    panic(err2)
}
fmt.Printf(awsutil.StringValue(b))

这是输出的内容:http://imgur.com/3MnBNXI这就是我想要的输出:

{

Snapshots:

如果您想打印单个快照的详细信息，您可以迭代响应:

resp, err := svc.DescribeSnapshots(params)
if err != nil {
    log.Fatal(err)
}
for i, s := range resp.Snapshots {
    fmt.Printf("Snapshot: %d\n", i)
    fmt.Println(s)
}
