I'm trying to convert this javascript code into Golang with no success.
function hexToBase64(value) {
const xxx = value.replace(/\r|\n/g, '').replace(/([\da-fA-F]{2}) ?/g, '0x$1 ').replace(/ +$/, '').split(' ');
const xx1 = String.fromCharCode.apply(null,xxx);
return btoa(xx1);
}
const item = hexToBase64("8953bed713db2113b8e8215b444b7d3e4bca6c139d3d54bb77f8cf7f07ca5482");
console.log(item);
OUTPUT: iVO+1xPbIRO46CFbREt9PkvKbBOdPVS7d/jPfwfKVII=
My code in golang, but it doesn't generate the same result
hexToBase64 := func(input string) string {
x := regexp.MustCompile(`\r|\n`).ReplaceAllString(string(input), "")
x1 := regexp.MustCompile(`([\da-fA-F]{2}) ?`).ReplaceAllString(x, "0x$1 ")
x2 := regexp.MustCompile(` +$`).ReplaceAllString(x1, "")
x3 := strings.Split(x2, " ")
var value string
for _, v := range x3 {
v = strings.Replace(v, "0x", "", -1)
i, e := strconv.ParseUint(v, 16, 64)
if e != nil {
panic(e)
}
value = value + string(rune(i))
}
return base64.StdEncoding.EncodeToString([]byte(value))
}
Can you help me?
Use the encoding/hex DecodeString function as suggested by rustyx in a comment:
func hexToBase64(s string) (string, error) {
b, err := hex.DecodeString(s)
return base64.StdEncoding.EncodeToString(b), err
}
Use this code to ignore whitespace in the hex string:
var killWS = strings.NewReplacer("\n", "", "\r", "", " ", "", "\t", "")
func hexToBase64(s string) (string, error) {
b, err := hex.DecodeString(killWS.Replace(s))
return base64.StdEncoding.EncodeToString(b), err
}
Resolved!
hexToBase64 := func(input string) string {
x := regexp.MustCompile(`\r|\n`).ReplaceAllString(string(input), "")
x1 := regexp.MustCompile(`([\da-fA-F]{2}) ?`).ReplaceAllString(x, "0x$1 ")
x2 := regexp.MustCompile(` +$`).ReplaceAllString(x1, "")
x3 := strings.Split(x2, " ")
var value string
for _, v := range x3 {
v = strings.Replace(v, "0x", "", -1)
ele, e := hex.DecodeString(v)
if e != nil {
return ""
}
value = value + string(ele)
}
return base64.StdEncoding.EncodeToString([]byte(value))
}
