如何索引aws快照输出？

Question

在这里，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。我不确定如何做到这一点，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 这是我想要输出的内容：

{

Snapshots:

----0

  Description: "Snapshot from MULTI",

  Encrypted: false,

  OwnerID: "130300684064",

  Progress: "100%!"(MISSING),

  SnapshotID: "snap-81b1dff6",

  StartTime: 2015-07-21 18:41:54 +0000 UTC,

  State: "completed",

  VolumeID: "vol-5121ebaa",

  VolumeSize: 1

},{

----1

  Description: "Snapshot from MULTI",

  Encrypted: false,

  OwnerID: "130300684064",

  Progress: "100%!"(MISSING),

  SnapshotID: "snap-08352a7f",

  StartTime: 2015-07-21 18:41:54 +0000 UTC,

  State: "completed",

  VolumeID: "vol-9b21eb60",

  VolumeSize: 1

},{

----2

  Description: "Snapshot from MULTI",

  Encrypted: false,

  OwnerID: "130300684064",

  Progress: "100%!"(MISSING),

  SnapshotID: "snap-768ffb00",

  StartTime: 2015-07-21 18:41:54 +0000 UTC,

  State: "completed",

  VolumeID: "vol-5620eaad",

  VolumeSize: 1

}]

如果要打印单个快照的详细信息，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)}
