title: chrome 插件实现mac地址获取 tags:

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。
-
准备宿主端，我们称之为host
-
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
manifest

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); } } } }); 复制代码host开发
