Hello,
maybe i'm bad understand to json.Unmarshal and slices.
I've data in json:
vals :=
`[{"time":"20160902","value":572736},{"time":"20160903","value":567616},{"time":"20160904","value":554560},{"time":"20160905","value":565600},{"time":"20160906","value":554752},{"time":"20160907","value":555744},{"time":"20160908","value":551392},{"time":"20160909","value":558272},{"time":"20160910","value":545696},{"time":"20160911","value":528032},{"time":"20160912","value":560960},{"time":"20160913","value":560480},{"time":"20160914","value":561920},{"time":"20160915","value":561216},{"time":"20160916","value":564512},{"time":"20160917","value":552352},{"time":"20160918","value":524960},{"time":"20160919","value":562688},{"time":"20160920","value":577632},{"time":"20160921","value":564704},{"time":"20160922","value":567296},{"time":"20160923","value":564544},{"time":"20160924","value":570944},{"time":"20160925","value":576224},{"time":"20160926","value":594176},{"time":"20160927","value":590784},{"time":"20160928","value":561184},{"time":"20160929","value":563744},{"time":"20160930","value":560928}]`
//Stucture for them is:
type tData struct{
time string
value float64
}
//And for location i've structure:
type tReport struct{
//Siteid int
Mname string
Vals []tData
}
//I must Unmarshal data into tReport.Vals. Fragments of code:
var report []tReport
var dat []tData
if err := json.Unmarshal([]byte(vals), &dat); err != nil {
ml.ErrInfo(err, verboseFlag)
}
fmt.Println("Data::")
fmt.Println(dat)
report = append(report, tReport{Mname: mname, Vals: nil})
//EOF code
But line fmt.Println(dat) shows me only: [{ 0} { 0} { 0} { 0} { 0} { 0} {
0} { 0} { 0} { 0} { 0} { 0} { 0} { 0} { 0} { 0} { 0} { 0} { 0} { 0} { 0} {
0} { 0} { 0} { 0} { 0} { 0} { 0} { 0}]
I don't understand why :-(.
Thank for Your help
