主要是在Pre-request Script中预处理一下

var ak = "2f567a1b";
var sk = "4a134596";
var time = Math.round(new Date().getTime());
var pageindex = 1;
var pagesize = 10;

//待加密明文
var str = ak+";"+sk+";"+time+";?pageindex="+pageindex+"&pagesize="+pagesize+";"
//MD5加密
var token = CryptoJS.MD5(str).toString();

// 设置全局变量
pm.environment.set("ak",ak);
pm.environment.set("sk", sk);
pm.environment.set("time", time);
pm.environment.set("pageindex", pageindex);
pm.environment.set("pagesize", pagesize);
pm.environment.set("token", token);
