postman设置、获取全局变量方法

//解析返回数据
var jsondata=JSON.parse(responseBody);
var token=jsondata.data.accessToken;

var timestamp = Math.round(new Date().getTime());
console.log(timestamp);
postman.setGlobalVariable("timestamp",timestamp);//设置取全局变量值1
pm.globals.set("token", token);      //设置取全局变量值2
pm.environment.set("envtoken",token) //设置环境变量值
var a =pm.environment.get("token")   //获取全局变量值
var b =pm.environment.get("envtoken")//获取环境变量值
