Connecting to Coinex API issue - rest

Question

I try to connect to Coinex API through a Java program
I follow exact patter that mentioned in below link for authorisation
https://github.com/coinexcom/coinex_exchange_api/wiki/012security_authorization
I MD5 has whole query string that is like below , and put result in authorization in request header parameter
tonce=1635504041595&access_id=XXXX&secret_key=YYYY
My intentions is to get account balance so my Get request URL is
https://api.coinex.com/v1//balance/info?tonce=1635504041595&access_id=XXXX
but server return below error
{"code": 25, "data": {}, "message": "Signature Incorrect"}
Anybody can advice what is the issue , thanks AndyJ

Answer 1

well this is my encode method:
public static String encode(String str) {
try {
// Generate a summary of MD5 encryption calculations
MessageDigest md = MessageDigest.getInstance("MD5");
md.update(str.getBytes("UTF-8"));
// digest() finally determines to return the md5 hash value, returning a value of 8 as a string. Because the md5 hash value is a 16-bit hex value, it is actually an 8-bit character.
// The BigInteger function converts an 8-bit string into a 16-bit hex value, represented by a string; gets a hash value in the form of a string
String md5 = new BigInteger(1, md.digest()).toString(16);
//BigInteger will omit 0 and need to be completed to 32 bits
return fillMD5(md5).toUpperCase();
} catch (Exception e) {
e.printStackTrace();
return "";
}
}
and one more thing,
your timestmap should have 10 digits, remove the last 3 "000" like this:
Integer.parseInt(String.valueOf(timestamp).substring(0, 10));
