开发说明
1、浏览器插件实现
manifest.json文件内容。每个chrome的插件都需要该文件,该文件记录插件的关键信息
{ "name" : "callapp", "version" : "1.0.1", "description" : "call local application", "background" : { "scripts": ["background.js"] }, "icons": { "16": "16.png", "128": "128.png" }, "permissions" : [ "nativeMessaging", "contextMenus", "tabs" ], "minimum_chrome_version" : "6.0.0.0", "manifest_version": 2 }
其中由于需要在右键菜单中增加选项,在permissions中增加"nativeMessaging"、"contextMenus"两项;需要和本地程序进行通讯,增加"nativeMessaging"项
maniffest.json所需要的background.js
//Author: jyx //Date: 2014.10.11 //Description: This is a javaScript file use for handle contextMenus action //When click the contextMenus, it will sent the infomation to native app //connect to native app var port = null; var nativeHostName = "com.ctrip.ops.mysql.callapp";//chrome与本地程序通信的桥梁,根据该名称进行配置项的寻找。windows下在注册表HKEY_CURRENT_USER\Software\Google\Chrome\NativeMessagingHosts内寻找,linux下在目录/etc/opt/chrome/native-messaging-hosts/寻找该名称的json文件(本例子为com.ctrip.ops.mysql.callapp.json) //onNativeDisconnect function onDisconnected() { //alert("连接到FastDownload服务失败: " + chrome.runtime.lastError.message); port = null; } //connect to native host and get the communicatetion port function connectToNativeHost() { port = chrome.runtime.connectNative(nativeHostName);//根据配置文件连接到本地程序 port.onDisconnect.addListener(onDisconnected); } //调用connectToNativeHost函数连接到本地程序,完成后使用port.postMessage函数将纤细传递给应用程序 //将信息写入I/O流与本地程序通信 function getClickHandler() { return function(info, tab) { connectToNativeHost(); port.postMessage(info.linkUrl); }; }; //在浏览器启动时即创建右键菜单,在页面链接上右击鼠标会显示该菜单,当点击"start program"的时候就会调用getClickHandler()函数处理 chrome.contextMenus.create({ "title" : "start program", "type" : "normal", "id": "callapp", "contexts" : ["link"], "enabled": true, "onclick" : getClickHandler() });
程序中nativeHostName需要特殊说明,正是通过该变量,chrome的插件找到调用本地程序的配置
本文的实验环境为windows7,在注册表的HKEY_CURRENT_USER\Software\Google\Chrome\NativeMessagingHosts中创建对应的项,注册表导出内容如下Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Google\Chrome\NativeMessagingHosts\com.ctrip.ops.mysql.callapp] @="D:\\temp\\chromeExtension\\callapp\\callapp.json"
linux下参考http://match-yang.blog.163.com/blog/static/2109902542014319103739996/
2、浏览器调用配置
callapp.json
该文件的路径保存在注册表的HKEY_CURRENT_USER\Software\Google\Chrome\NativeMessagingHosts\com.ctrip.ops.mysql.callapp项内
{ "name": "com.ctrip.ops.mysql.callapp", "description": "Chrome call native app and sent message to app.", "path": "C:\\MyApp.exe", "type": "stdio", "allowed_origins": [ "chrome-extension://imcfacgnnkhdheiajocckejfmeiokgol/" ] }
3、本地应用程序例子
使用C#进行开发,C++参考http://match-yang.blog.163.com/blog/static/2109902542014319103739996/
using System; using System.IO; namespace ConsoleApplication8 { class Program { static void Main(string[] args) { log2file("--------------------program start at " + DateTime.Now.ToString() + "--------------------"); if (args.Length != 0) { for (int i = 0; i < args.Length; i++) log2file("arg " + i.ToString() + args[i]); string chromeMessage = OpenStandardStreamIn(); log2file("--------------------My application starts with Chrome Extension message: " + chromeMessage + "---------------------------------"); } log2file("--------------------program end at " + DateTime.Now.ToString() + "--------------------"); } static void log2file(string s) { FileStream fs = new FileStream(@"c:\test.log", FileMode.Append); StreamWriter sw = new StreamWriter(fs); sw.WriteLine(s); sw.Close(); fs.Close(); } private static string OpenStandardStreamIn() { //// We need to read first 4 bytes for length information Stream stdin = Console.OpenStandardInput(); int length = 0; byte[] bytes = new byte[4]; stdin.Read(bytes, 0, 4); length = System.BitConverter.ToInt32(bytes, 0); string input = ""; for (int i = 0; i < length; i++) { input += (char)stdin.ReadByte(); } return input; } } }
说明:
background.js代码根据如下链接,进行了一些非框架性的修改,主要是注释,不过还是修改了一下author
