Jmeter - Calling javascript using JSR223 Post processor

I capture 6 elements using a regular expression. say

Variable : UserDetails
Regular Expression : loadHeadWorkFlow\('(.+?)','(.+?)','(.+?)','(.+?)','(.+?)','(.+?)','/I
Template : $1$$2$$3$$4$$5$$6$

Now I could access these values via UserDetails_g1, UserDetails_g2.....UserDetails_g6

Next, these 6 values need to be encrypted using a javascript file. The file contains the logic.

How should my code be using JSR223 post processor?

The steps that I followed:

1.

load('Encryption.js');

   var result = encrypt("${UserDetails_g1}","password");
   log.info("encrypted value is "+result);
   vars.put("LoginDataString",result);

   var result1 = encrypt("${UserDetails_g2}","password1");
   vars.put("UserId",result1);

   var result2 = encrypt("${UserDetails_g3}","password2");
   vars.put("RoleId",result2);

First value is encrypted correctly. But the other values aren't correct. If I add individual post processors for every variable. All the encrypted values show correctly.

Is there a way where I could use a single post processor to perform all the 6 encryptions. Thanks in advance

Regards, Ajith

Use vars instead of ${} syntax

 var result = encrypt(vars.get("UserDetails_g1"),"password");
 log.info("encrypted value is "+result);
 vars.put("LoginDataString",result);

 var result1 = encrypt(vars.get("UserDetails_g2"),"password1");
 vars.put("UserId",result1);

 var result2 = encrypt(vars.get("UserDetails_g3"),"password2");
 vars.put("RoleId",result2);

From JMeter perspective there is no problems, just check that your UserDetails_g2 variable has anticipated value using Debug Sampler and View Results Tree listener combination., the you might want to check this encrypt() function implementation.

Another possible reason is this JavaScript language selection itself, the Nashorn engine performance is a big question mark when it comes to the load, according to JMeter Best Practices it's recommended to use Groovy language for scripting so you might want to consider re-writing the function in Groovy
