重点:
1、jmeter中的jsr223 preprocessor中内嵌的javascript版本是ECMA 5.1,postman中可以执行的脚本(ECMA 6),过来需要进行降级实现(ECMA 5.1)
2、jmeter压测中的number of threads(users)代表并发数,ramp-up period(seconds)代表多少秒内发起users,duration(seconds)代表持续多长时间
可被执行的javascript代码:
//加载外部资源

load("https://www.xxx.com/crypto-js-3.1.2/hmac.js");

load("https://www.xxx.com/crypto-js-3.1.2/sha256.js");//加密函数

}

//5.1语法
var plainText = '';
