Unbale 在 jmetter 中运行 crypto-js

Question

I'm trying to run crypto-js in PreProcessor JSR223 but i have an error (see below. I don't found a solution to resolve it, can you check please?

javax.script.ScriptException: SyntaxError: crypto-js.js:1424:48 Expected , but found =
            stringify: function (wordArray, urlSafe=true) {

Load cryptoJs.js with success

Nashorn is a Java implementation which supports ECMAScript 5.1

ECMAScript 5.1 was released in 2011 and now it's 2023 that's why it cannot support ECMAScript 6 or higher, that's why you're getting the error.

You could try looking for an archive version of crypto-js which is ECMAScript 5.1 compatible but I don't think it's something you should be doing because Nashorn itself was removed in OpenJDK 15

So I would recommend re-implementing your cryptography logic in Groovy language, moreover it's t he most performing scripting engine andit's recommended for using by JMeter authors .
