Go: What's the best way to detect invalid JSON string characters? -


what's best, efficient way detect whether go string contains characters invalid in json strings? in other words, what's go equivalent answer java question? use strings.containsany (assuming ascii control characters)?

ctlchars := string([]byte{     0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18,     19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 127, }) if strings.containsany(str, ctlchars) {     println("has control chars") }

if looking identify control characters (as in answers java question pointed to), might want use unicode.iscontrol simpler solution.

https://golang.org/pkg/unicode/#iscontrol

func containscontrolchar(s string) bool {     _, c := range s {         if unicode.iscontrol(c) {             return true         }     }     return false }
