Chrome extension - WebSocket No Connection Made

[איתמר פרץ‎]

I'm using WebSocket in order to send data from chrome extension to local Java application.

The JS code in the chrome application is :

    var ws = new WebSocket("ws://127.0.0.1:8080/");

    

    ws.onopen = function() {

    alert("Opened!");

    ws.send("Hello Server");

    };

    

    ws.onmessage = function (evt) {

    alert("Message: " + evt.data);

    };

    

    ws.onclose = function() {

    alert("Closed!");

    };

    

    ws.onerror = function(err) {

    alert("Error: " + err);

    };

The problem comes up when no connection is ever made .I've tested the server side by simply running the JS code above , with no connection to any Chrome extension, simply through Chrome browser, and it has worked just fine.

I'd like to know why I cannot create WebSocket connection from Chrome addon, and I'd be grateful if anyone could point me to the solution.

Thanks in advance.

The code should work. I also use WebSockets in one of my addons. One reason it might be failing is the URL request is being redirected by a proxy switcher extension (e.g. FoxyProxy). I haven't found a single proxy switcher that can handle "ws://" URLs properly.

Did you add the domain (without the port) to the permission key in the manifest?
