Chrome nativeclient Create

Chrome nativeclient Create

The demo goal is to have the Chrome extension launch the local exe

1 Creating a console program called Nativemsgdemo

#include <Windows.h>

#include <iostream>

#include <string>

#include <fstream>

using namespace Std;

BOOL Recievemsgfromchrome ();

int main (int argc, char* argv[])

{

while (1)

{

Sleep (300);

if (! Recievemsgfromchrome ())

Break

}

return 1;

}

The generated exe is nativeMsgDemo.exe

2. Extending the content to be written

Write content in the extended background.js so that the Chrome extension supports nativeclient message response

var port = chrome.runtime.connectNative (' Com.wudi.chrome.namsg.yunzhou ');

Port.onMessage.addListener (function (msg) {

Console.log ("Received" + msg);

});

Port.onDisconnect.addListener (function () {

Console.log ("Disconnected");

});

Port.postmessage ({text: "Hello, My_application"});

3. Chrome nativemessaginghosts Registry File

Com.wudi.chrome.namsg.yunzhou writing to the registry

Hkey_local_machine\software\google\chrome\nativemessaginghosts\com.wudi.chrome.namsg.yunzhou

Find the path to the. json file through this registry

D:\projects\NativeMsgDEmo\output\com.wudi.chrome.namsg.yz-win.json,

In this file , the EXE that chrome.runtime.connectNative True Association communication is saved , the file content is as follows:

{

"Name": "Com.wudi.chrome.namsg.yunzhou",

"description": "Chrome Native Messaging for Yuzhou",

"Path": "NativeMsgDemo.exe",

"Type": "Stdio",

"Allowed_origins": [

"Chrome-extension://hohonaplgfolmdaaafoddgbiakognoal/"

]

}

The . json file and the. EXE file are typically placed in the same directory for easy locating, such as:

Then let chrome load our extension,backgroud.html will load backgroud.js,background.js in the Chrome.runtime.connectNative will get the EXE that communicates with Chrome , which is the standard input/output.

4. nativeclient. exe search process

1. Via var in background.js port =

Chrome.runtime.connectNative (' Com.wudi.chrome.namsg.yunzhou ');

Locate the registry key in the hkey_local_machine\software\google\chrome\nativemessaginghosts

Com.wudi.chrome.namsg.yunzhou

2. Locate the Com.wudi.chrome.namsg.yz-win.json file by using the above registry key

3. exe with connection input and output specified in the Com.wudi.chrome.namsg.yz-win.json file
