我有以下格式的原始 json-
"luns": [
{
"numReadBlocks": 15444876,
"numWriteBlocks": 13530714,
"blockSizeInBytes": 512,
"writeIops": 495344,
"readIops": 312702,
"serialNumber": "aaaaaaa",
"uuid": "id",
"shareState": "none",
"usedBytes": 6721716224,
"totalSizeBytes": 16106127360,
"path": "/vol/lun_23052014_025830_vol/lun_23052014_025830"
},
{
"numReadBlocks": 15444876,
"numWriteBlocks": 13530714,
"blockSizeInBytes": 512,
"writeIops": 495344,
"readIops": 312702,
"serialNumber": "aaaaaaa",
"uuid": "id",
"shareState": "none",
"usedBytes": 6721716224,
"totalSizeBytes": 16106127360,
"path": "/vol/lun_23052014_025830_vol/lun_23052014_025830"
}]
luns 可能包含列表。我想处理上面的json并形成如下输出 -
"topStorageLuns": [
{
"name": "Free (in GB)",
"data": [7.79,7.79]
},
{
"name": "Used (in GB)",
"data": [7.21,7.21]
}]
我尝试跟随以获得输出-
val storageLuns = myRawJson
val topStorageLuns = storageLuns.map { storageLun =>
val totalLunsSizeOnStorageDevice = storageLun.luns.foldLeft(0.0) {
case (totalBytesOnDevice, lun) =>
totalBytesOnDevice + lun.usedBytes.getOrElse(0.0).toString.toLong
}
val totalAvailableLunsOnStorageDevice = storageLun.luns.foldLeft(0.0) {
case (totalBytesOnDevice, lun) =>
totalBytesOnDevice + lun.usedBytes.getOrElse(0.0).toString.toLong
}
Json.obj("name" -> storageLun.hostId, "data" -> "%.2f".format(totalLunsSizeOnStorageDevice / (1024 * 1024 * 1024)).toDouble)
}
任何人都可以帮我获得所需的输出吗???
