Hi Chriss,
Hi executed below Groovy code with JSR223 sampler and got an error for that.
*Code:*
import javax.crypto.Mac
import javax.crypto.spec.SecretKeySpec
import java.util.Base64
// Retrieve environment variables (using System.getenv as an example)
def key = System.getenv("d552a1b3-3558-3c47-b34a-1ba87558b74b") ?:
"defaultKey"
def secret = System.getenv("vz7noe5z17i2usV58oFR5YMtU1BUFL0Ah9+eXuwV6IQ=")
?: "am1ldGVy"
def ts = System.currentTimeMillis()
def baseString = "${key}-2-${ts}"
// Decode the secret from Base64
def secretDecoded = Base64.decoder.decode(secret)
// Generate HMAC-SHA256 hash
Mac mac = Mac.getInstance("HmacSHA256")
mac.init(new SecretKeySpec(secretDecoded, "HmacSHA256"))
byte[] macSignature = mac.doFinal(baseString.getBytes("UTF-8"))
// Encode the signature to Base64 and sanitize it
def macSignatureBase64 = Base64.encoder.encodeToString(macSignature)
.replace("=", "")import javax.crypto.Mac
import javax.crypto.spec.SecretKeySpec
import java.util.Base64
// Retrieve environment variables (using System.getenv as an example)
def key = System.getenv("appKey") ?: "defaultKey"
def secret = System.getenv("appSecret") ?: "am1ldGVy"
def ts = System.currentTimeMillis()
def baseString = "${key}-2-${ts}"
// Decode the secret from Base64
def secretDecoded = Base64.decoder.decode(secret)
// Generate HMAC-SHA256 hash
Mac mac = Mac.getInstance("HmacSHA256")
mac.init(new SecretKeySpec(secretDecoded, "HmacSHA256"))
byte[] macSignature = mac.doFinal(baseString.getBytes("UTF-8"))
// Encode the signature to Base64 and sanitize it
def macSignatureBase64 = Base64.encoder.encodeToString(macSignature)
.replace("=", "")
.replace("+", "-")
.replace("/", "_")
// Simulated environment variable storage (Postman equivalent)
def environment = [:] // A map to mimic Postman environment variables
environment["signature"] = macSignatureBase64
environment["timestamp"] = ts
// put the result in jmeter vars
vars.put("signature",macSignatureBase64)
vars.put("timestamp","" + ts)
// Debug output
println "Signature: ${macSignatureBase64}"
println "Timestamp: ${ts}"
*Getting this error:*
