使用jsr223向jMeter添加javascript函数 [英] Adding javascript function to jMeter using jsr223

问题描述

我正在尝试使用JSR223的jMeter测试计划来获取一个JavaScript函数。
它用于解码字符串。
我有以下两个函数，我需要在jmeter中实现：

 函数AESEncryption（文本，通过，bytessize ）{
 
 var key = CryptoJS.enc.Utf8.parse（'ABCDEFGHIJKL1234567891234'）; 
 var iv = CryptoJS.enc.Utf8.parse（'1234567890123456'）; 
 var blocksize = bytessize / 2; 
 var encrypted = CryptoJS.AES.encrypt（CryptoJS.enc.Utf8.parse（text），passphase，key，
 {
 keySize：bytessize，
 iv：iv，
模式：CryptoJS.mode.CBC，
 padding：CryptoJS.pad.Pkcs7 
}）; 
 var dta = String（encrypted）; 
 return dta;} 
 
 
函数AESDecryption（文本，键，bytessize）{
 try {
 // alert（text +：+键+：+ bytessize）; 
 var e = CryptoJS.AES.decrypt（text，key，bytessize）; 
 // alert（Ec：+ e）; 
 return CryptoJS.AES.decrypt（text，key，bytessize）.toString（CryptoJS.enc.Utf8）; 
} 
 catch（错误）{
 return;}} 
  

解决方案

您可以使用 load 指令将外部JavaScript导入JSR223 Sampler。

1. 从

$ b请注意，通过Rhino / Nashorn解释的JavaScript具有严重的性能缺陷，因此如果您打算通过许多线程调用此功能，则在 Groovy 。

I am trying to get a javascript function work with jMeter test plan uing JSR223. It is used to decode a string. I have the below two functions which i need to implement in jmeter:

function AESEncryption(text, passphase, bytessize) {

var key = CryptoJS.enc.Utf8.parse('ABCDEFGHIJKL1234567891234');
var iv = CryptoJS.enc.Utf8.parse('1234567890123456');
var blocksize = bytessize / 2;
var encrypted = CryptoJS.AES.encrypt(CryptoJS.enc.Utf8.parse(text), passphase, key,
{
    keySize: bytessize,
    iv: iv,
    mode: CryptoJS.mode.CBC,
    padding: CryptoJS.pad.Pkcs7
});
var dta = String(encrypted);
return dta;}


function AESDecryption(text, key, bytessize) {
try {
    //alert(text + ":" + key + ":" + bytessize);
    var e = CryptoJS.AES.decrypt(text, key, bytessize);
    //alert("Ec:" + e);
    return CryptoJS.AES.decrypt(text, key, bytessize).toString(CryptoJS.enc.Utf8);
}
catch (Error) {
    return "";}}

解决方案

You can import external JavaScript into JSR223 Sampler using load directive.

1. Download latest release of crypto-js from https://github.com/brix/crypto-js/releases (I used 3.1.9) and unpack it to JMeter's "bin" folder

2. Add the next line to the beginning of your JSR223 script:

   load('crypto-js-3.1.9/crypto-js.js');
   

3. You should be able to access your JavaScript functions directly in the JSR223 Sampler

Be aware that JavaScript being interpreted via Rhino/Nashorn has serious performance drawbacks therefore if you are planning to call this funciton by many threads it makes more sense to rewrite your functions in Groovy.
