web worker 发送Ajax

1、引入无dom的jquery

importScripts("js/jquery.nodom.js");
下载地址：jquery.nodom.js

2、这时候就可以直接用ajax啦

function changeMode(){
    var endoding= "admin:password";
    //var encoding = $.base64.encode(code);
    $.ajax({
        type: "GET",
        // url: "http://{{ip}}/ccpiot/api/assignments/{{token}}/measurements?page=1&pageSize=1",
        url: "http://192.168.20.201:8089/ccpiot/api/assignments/ec1a83f6_d2a9_4d45_b68b_1f41070441ad/measurements?page=1&pageSize=1",
        async: false,
        timeout: 1000,
        success: function (datab) {
            self.postMessage(num)//向主线程发消息
        },
        error: function (data) {
            console.log(data)
        },
        beforeSend: function (xhr) {
            xhr.setRequestHeader("Authorization", " Basic " + encoding);
            xhr.setRequestHeader("X-SiteWhere-Tenant", "lab517");
        }
    })
}

changeMode();
setInterval(function (){
        changeMode();
},20000);
