Simple question: how to parse a string (which is an array) in Go using json package?
type JsonType struct{
Array []string
}
func main(){
dataJson = `["1","2","3"]`
arr := JsonType{}
unmarshaled := json.Unmarshal([]byte(dataJson), &arr.Array)
log.Printf("Unmarshaled: %v", unmarshaled)
}
The return value of Unmarshal
is an err, and this is what you are printing out:
// Return value type of Unmarshal is error.
err := json.Unmarshal([]byte(dataJson), &arr)
You can get rid of the JsonType
as well and just use a slice:
package main
import (
"encoding/json"
"log"
)
func main() {
dataJson := `["1","2","3"]`
var arr []string
_ = json.Unmarshal([]byte(dataJson), &arr)
log.Printf("Unmarshaled: %v", arr)
}
// prints out:
// 2009/11/10 23:00:00 Unmarshaled: [1 2 3]
