读取某变量的值(xhr

var data = null;

var xhr = new XMLHttpRequest();
xhr.withCredentials = true;

xhr.addEventListener("readystatechange", function () {
  if (this.readyState === 4) {
    console.log(this.responseText);
  }
});

xhr.open("GET", "http://127.0.0.1:39321/iotgateway/read?ids=Channel1.Device1.tag1,Channel1.Device1.tag2");
xhr.setRequestHeader("Connection", "keep-alive");
xhr.setRequestHeader("Cache-Control", "max-age=0");
xhr.setRequestHeader("Upgrade-Insecure-Requests", "1");
xhr.setRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.81 Safari/537.36");
