qiang-gao-cn解析UA的代码：

var result = dataobj[i];
var Devices;
if ( result.indexOf("crawler") != -1 || result.indexOf("Java") != -1 || result.indexOf("Go-http-client") != -1 || result.indexOf("WhatsApp") != -1 || result.indexOf("curl") != -1 || result.indexOf("Test") != -1) {
        Devices = "bot";
 } else if (result.indexOf("Apple TV") != -1 || result.indexOf("CrKey") != -1 || result.indexOf("Roku") != -1 || result.indexOf("AFTS") != -1 || result.indexOf("SmartTV") != -1 || result.indexOf("NetCast") != -1) {
           Devices = "TV";
 } else if (result.indexOf("Windows") != -1) {
           if (result.indexOf("Android") != -1) {
    Devices = "Android";

qiang-gao-cn判断比较与dao-lab判断：

windows的进一步判断；因为win98 或win95区别于windwos NT的判断；
Android的判断；因为Android是使用linux内容，所以Android的user-agent会同时包含Android和linux两个字符；
