Chrome通过Native Message 扩展程序获取windows MAC地址

2016-03-17 13:45 507 查看

Chrome Native Message的原理网上有很多的文章介绍，本片文章就不介绍了。小编研究了一周的时间，终于完成了获取Mac地址的扩展开发。由于网上给出的例子都是跑不通的，分享给大家参考。

1、编写C++代码获取MAC地址

#include <stdio.h>

#include <windows.h>

#include <string>

#include <Assert.h>

#include <iphlpapi.h>

#include <stdio.h>

#include <stdlib.h>

#include <cstdlib>

#include <unistd.h>

#include <iostream>

#define WIN32_LEAN_AND_MEAN // Exclude rarely-used stuff from Windows headers

static std::string GetMACaddress(void)

{
IP_ADAPTER_INFO AdapterInfo[16];
// Allocate information for up to 16 NICs
DWORD dwBufLen = sizeof(AdapterInfo);
// Save the memory size of buffer

DWORD dwStatus = GetAdaptersInfo(
// Call GetAdapterInfo
AdapterInfo,
// [out] buffer to receive data
&dwBufLen);
// [in] size of receive data buffer
assert(dwStatus == ERROR_SUCCESS);
// Verify return value is valid, no buffer overflow

PIP_ADAPTER_INFO pAdapterInfo = AdapterInfo;// Contains pointer to current adapter info
std::string outMsg = "";
do {
char acMAC[32];
sprintf(acMAC, "%02X-%02X-%02X-%02X-%02X-%02X",
int (pAdapterInfo->Address[0]),
int (pAdapterInfo->Address[1]),
int (pAdapterInfo->Address[2]),
int (pAdapterInfo->Address[3]),
int (pAdapterInfo->Address[4]),
int (pAdapterInfo->Address[5]));
outMsg.append(acMAC);
outMsg.append(",");
pAdapterInfo = pAdapterInfo->Next;
// Progress through linked list
}
while(pAdapterInfo);
if(outMsg.length()>5){
outMsg = outMsg.substr(0,outMsg.length()-1);
}

    return outMsg;

}

int main(int argc, _TCHAR* argv[]){
 std::string outMsg = "{\"text\":\""+GetMACaddress()+"\"}";
 unsigned int outLen = outMsg.length();
 char *bOutLen = reinterpret_cast<char *>(&outLen);
 std::cout.write(bOutLen, 4);
 std::cout << outMsg << std::flush;
 return 0;

}

静态编译成.exe  文件

2、编写Chrome Extensions

chrome扩展包含两个部分 host和app。
host调用C++ .exe文件，并在注册表中注册；
app可添加到chrome扩展中，供web页面调用；

2.1首先看host文件内容，host文件夹下文件列表如下图：

其中uninstall_host.bat文件是将C++程序从注册表中删除，install_host是安装c++程序到注册表中，GetMac.exe是编译后的C++程序，
最后的.json文件内容如下：
参数说明请参考：https://developer.chrome.com/extensions/nativeMessaging
{

  "name": "com.google.chrome.fmb.getmac.echo",

  "description": "Chrome Native Messaging API Example Host",

  "path": "GetMac.exe",

  "type": "stdio",

  "allowed_origins": [

    "chrome-extension://knldjmfmopnpolahpmmgbagdohdnhkik/"

  ]

}


2.2 再看app文件内容，app文件夹下文件列表如下图：

main.js和main.html 可以做测试用的，

main.js代码如下：

var port = null;  

    

function appendMessage(text) {  

  document.getElementById('response').innerHTML += "<p>" + text + "</p>";  

}  

  

function sendNativeMessage() {  

  message = {"text": document.getElementById('input-text').value};  

  port.postMessage(message);  

  appendMessage("Sent message: <b>" + JSON.stringify(message) + "</b>");  

}  

  

function onNativeMessage(message) {  

  appendMessage("Received message: <b>" + JSON.stringify(message) + "</b>");  

}  

  

function onDisconnected() {  

  appendMessage("Failed to connect: " + chrome.runtime.lastError.message);  

  port = null;  

}  

  

function connect() {  

  var hostName = "com.google.chrome.fmb.getmac.echo";  

  appendMessage("Connecting to native messaging host <b>" + hostName + "</b>")  

  port = chrome.runtime.connectNative(hostName);  

  port.onMessage.addListener(onNativeMessage);  

  port.onDisconnect.addListener(onDisconnected);  

}  

  

document.addEventListener('DOMContentLoaded', function () {  

  document.getElementById('connect-button').addEventListener(  

      'click', connect);  

});  

[b]main.html代码如下：[/b]
<html>  

  <head>  

    <script src='./main.js'></script>  

  </head>  

  <body>  

    <button id='connect-button'>Connect</button>  

    <div id='response'></div>  

  </body>  

</html>

background.js里面实现与host的通信，代码如下：

var port = null;

var hostName = "com.google.chrome.xxx.getmac.echo";

var mac = {};

function connect() {
port = chrome.runtime.connectNative(hostName);
port.onMessage.addListener(onNativeMessage);
port.onDisconnect.addListener(onDisconnected);

}

function onNativeMessage(message) {
mac = message; 
chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
   chrome.tabs.sendMessage(tabs[0].id, mac , function(response) {
       //alert("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!=undefined && mac.text!=null && mac.text!=""){

      sendResponse(mac);

      }
  

      }

       }

  });

content.js能够接受background发送的消息，可以实现与应用页面交互将消息传到页面，可以在content中访问页面的dom 。 content.js代码如下：

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
if(request.text != undefined && request.text!=null && request.text!=""){
document.getElementById('mac_address').value = request.text;
}

});

manifest.json配置如下，此配置文件定义扩展程序，具体参数含义参考

https://developer.chrome.com/extensions/nativeMessaging

{

  //Extension ID: knldjmfmopnpolahpmmgbagdohdnhkik

  "key": "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDcBHwzDvyBQ6bDppkIs9MP4ksKqCMyXQ/A52JivHZKh4YO/9vJsT3oaYhSpDCE9RPocOEQvwsHsFReW2nUEc6OLLyoCFFxIb7KkLGsmfakkut/fFdNJYh0xOTbSN8YvLWcqph09XAY2Y/f0AL7vfO1cuCqtkMt8hFrBGWxDdf9CQIDAQAB",

  "name": "Native Messaging Example",

  "version": "1.0",

  "manifest_version": 2,

  "description": "Send a message to a native application.",

  "background" : { "scripts": ["background.js"] },

  "app": {

    "launch": {

      "local_path": "main.html"

    }

  },

  "icons": {

    "128": "icon-128.png"

  },

 "content_scripts": [  

    {  

      "matches": ["http://*/*"],  

      "js": ["content.js"]  

    }  

  ], 

  "externally_connectable": {"matches": ["http://test.fangmaidong.com/fmsj/*","http://localhost/fmsj/*","http://localhost:8080/fmsj/*"]},  

  "permissions": [

    "nativeMessaging","tabs", "http://*/*", "https://*/*"  

  ]

}

2.3应用系统页面代码实例

var editorExtensionId = "knldjmfmopnpolahpmmgbagdohdnhkik";
function sendMessage(type){
chrome.runtime.sendMessage(editorExtensionId, {requestType: type},
 function(response) {
if(response.text!=undefined && response.text!=null && response.text!=""){
document.getElementById('mac_address').value = response.text;
}
});
}

sendMessage('connect');

2.4在chrome扩展设置中添加此扩展程序

3、注意事项

Chrome 的启动参数需要设置 --enable--native-messaging
