Ok, so I looked at the
https://github.com/tidwall/gjson/blob/master/gjson.go code, and see that
the jsonvals slice is a slice of:
type Result struct {
// Type is the json type
Type Type
// Raw is the raw json
Raw string
// Str is the json string
Str string
// Num is the json number
Num float64
// Index of raw value in original json, zero means index unknown
Index int
}
So you will need to locate the index of the "ID" field in the slice and
presumably access the Num field. something like:
fmt.Printf("\n%+v\n", jsonvals[2].Num)
Good Luck,
