浏览器无法通过js获取到硬件信息众所周知，ie是也是通过ActiveX来完成的。

由于我们一直使用Chrome，因此考虑开发chrome插件。

普通chrome插件也是无法获取到mac地址等信息的，我们采取和本地通信app的实现。

1. 准备宿主端，我们称之为host

2. 准备插件端，我们称之为extension

   如上图所示，我们通过插件端和host进行通信，插件也可以通过授权来访问 指定的页面的document。在进行指定编码格式约定后就可以进行我们的编码了。

   对于chrome的插件开发我们就不说了，可以在网络上抄到一堆。

   插件开发

   content.js

   对应后需要增加content.js 负责和页面dom交互

       chrome.runtime.onMessage.addListener(function (request, sender, sendResponse) {
           console.debug("chrome.runtime.onMessage called");
           if (!!request.text) {
               console.debug("mac address:%s", request.text);
               var macEle = document.getElementById("mac");
               if (!!macEle) {
                   macEle.value = request.text
               }
           }
       });
   复制代码

   brankground.js

   增加和host通信的background.js

       var port = null;
       var hostName = "com.f6car.chrome.safe.echo";
       var mac = {};
       function connect() {
           port = chrome.runtime.connectNative(hostName);
           port.onMessage.addListener(onNativeMessage);
           port.onDisconnect.addListener(onDisconnected);
       }
        
       function onNativeMessage(message) {
           console.debug("nativemessage：%s",JSON.stringify(message));
           chrome.tabs.query({active: true}, function (tabs) {
               console.debug("tabs：%s",JSON.stringify(tabs));
               chrome.tabs.sendMessage(tabs[0].id, message, function (response) {
                   console.debug("baground  respone");
               });
           });
        
       }
        
       function onDisconnected() {
           port = null;
       }
        
       chrome.runtime.onMessageExternal.addListener(
           function (request, sender, sendResponse) {
               if (request.requestType === "connect") {
                   if (port === null) {
                       connect();
                   }
               }
               else {
                   if (port === null) {
                       connect();
                   }
                   else {
                       if (!!mac.text) {
                           sendResponse(mac);
                       }
