I have a piece of code written in java need to run it in jmeter. I am trying to execute this code in jmeter beanshell sampler but facing lots of error. can anyone help me with this. I want to extract now and urlEncodedSign in a variable and need to pass in the request.
public class Signature {
String[] replacementPairs = null;
public static void main(String args[]) throws GeneralSecurityException, IOException {
String key = GetKey();
long now = Instant.now().toEpochMilli();
System.out.println("key: " + key);
String s = String.valueOf(now);
System.out.println("value of s is " + s);
String salt = s;
String generateHmacSHA256Signature = generateHmacSHA256Signature(salt,
key);
System.out.println("Signature: " + generateHmacSHA256Signature);
String urlEncodedSign = URLEncoder.encode(generateHmacSHA256Signature,
"UTF-8");
System.out.println("Url encoded value: " + urlEncodedSign);
}
public static String GetKey() {
return Unify(new String[] {
"1_1", "1_2", "1_3", "1_4", "1_5"
},
new int[] {
4, 2, 0, 3, 1
},
new String[] {
"1_2", "2_2", "3_2", "4_2", "5_2", "6_2"
});
}
private static String Unify(String[] elements, int[] segments, String[] replacementPairs) {
String key = "";
System.out.println("Emptykey:" + key);
for (int segment: segments) {
if (key != null) {
key = key.concat(elements[segment]);
} else {
key = elements[segment];
}
}
if (replacementPairs != null) {
for (int i = 0; i < replacementPairs.length - 1; i = i + 2) {
key = key.replace(replacementPairs[i], replacementPairs[i + 1]);
}
}
return key;
}
public static String generateHmacSHA256Signature(String data, String key) throws GeneralSecurityException, IOException {
byte[] hmacData = null;
try {
SecretKeySpec secretKey = new SecretKeySpec(key.getBytes("UTF-8"),
"HmacSHA1");
Mac mac = Mac.getInstance("HmacSHA1");
mac.init(secretKey);
hmacData = mac.doFinal(data.getBytes("UTF-8"));
ByteArrayOutputStream bout = new ByteArrayOutputStream();
new Base64Encoder().encode(hmacData, 0, hmacData.length, bout);
return bout.toString("UTF-8");
} catch (UnsupportedEncodingException e) {
throw new GeneralSecurityException(e);
}
}
}
