扩展程序开发-打开本地应用

1、准备工作-目录结构

        1)、manifest是沟通后台的程序文件，必须要有

        2)、background.js、content.js、图标可自定义命名。

        3)、文件目录

                        

   2、manifest文件内容

        {

"name" :"扩展程序测试",

"version" :"1.0.1",

"description" :"init APP ",

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

"permissions" : ["file://*/*","http://*/","https://*/","downloads","nativeMessaging","storage","webRequest","webRequestBlocking","tabs"],

"content_scripts": [

{

"all_frames":true,

"matches": ["*://*/*" ],

"js": ["content.js" ],

"run_at":"document_idle"

      }

],

"icons": {

"512":"icons/ntko.png"

  },

"minimum_chrome_version" :"6.0.0.0",

"manifest_version":2

}

4、分别对应两个文件的路径

5、background.js文件内容

var port = null;

chrome.runtime.onMessage.addListener(function(request,sender,sendResponse) {

if (request.type=== "launch"){

connectToNativeHost(request.message);

}

return true;

});

//onNativeDisconnect

function onDisconnected() {

console.log(chrome.runtime.lastError);

console.log('disconnected from native app.');

port = null;

}

function onNativeMessage(message) {

console.log('recieved message from native app: ' + JSON.stringify(message));

}

//connect to native host and get the communicatetion port

function connectToNativeHost(msg)

{

var nativeHostName= "com.wisdombud.qingdao";

// console.log(nativeHostName);

  port = chrome.runtime.connectNative(nativeHostName);

const docmadsa= document.createElement('div',port)

document.body.append(docmadsa)

port.onMessage.addListener(onNativeMessage);

port.onDisconnect.addListener(onDisconnected);

port.postMessage({message: msg});

}

6、content.js

var launch_message;

document.addEventListener('myCustomEvent',function(evt) {

chrome.runtime.sendMessage({type: "launch", message: evt.detail},function(response) {

console.log(response)

});

},false);

7、然后通过扩展程序路径放到扩展程序上

8、然后新建三个文档ccc.text、install.reg、nativecall.json

            1)、ccc.text随便输入点文字

           2)、install.reg：需要匹配 nativecall.json 文件路径,然后保存双击此文件生成注册表

                                

                            

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\Google\Chrome\NativeMessagingHosts\com.wisdombud.qingdao]

@="C:\\native\\nativecall.json"

3) 、nativecall.json ：path: 匹配ccc.text

{

"name": "com.wisdombud.qingdao",

"description": "Chrome sent message to native app.",

"path": "C://native//ccc.text",

"type": "stdio",

"allowed_origins": [

"chrome-extension://aepcpdpmdgfhgjllbpngajemhiliogdh/"

]

}

9、找个文件随便写个html

10、打开浏览器、点击按钮就可以通过扩展程序，实现操作页面打开本机应用。
