How to send message to extension made request?-CodePudding

The

server.reg depends on the development folder C:\Users\norio\hoge, so you need to rewrite it according to your environment.

You need to install the psutil module.

manifest.json

{ "name": "hoge", "manifest_version": 3, "version": "1.0", "permissions": [ "activeTab", "nativeMessaging" ], "background": { "service_worker": "background.js" } }

background.js

const main = () => { console.log("main") const port = chrome.runtime.connectNative("server"); console.log(port) port.onMessage.addListener((message) => { console.log("Received: " message); port.postMessage("Message processed successfully"); }); } chrome.runtime.onInstalled.addListener(() => { main(); }); chrome.runtime.onStartup.addListener(() => { main(); });

server.json

{ "name": "server", "description": "Deleting this key will result in an error.", "path": "server.py", "type": "stdio", "allowed_origins": [ "chrome-extension://<Your Extension ID>/" ] }
