Session.cookies is empty while JavaScript document.cookie is not

Question

I want to get all the cookies from a BrowserWindow object, including HTTPonly cookies. I've read through the documentation that the following code will output all the cookies being used in the BrowserWindow: windowObject.webContents.session.cookies. This returns an empty cookies object: Cookies: {}.

If I use the following code, I do get all the cookies except for the much needed HTTPonly (which are not returned due to security purposes):

return windowObject.webContents.executeJavaScript(`document.cookie;`,true).then(function(result){
 console.log(result);
});

Proof of the issue; Place this code inside your app.on('ready') function:

const Window = electron.BrowserWindow;
var windowObject = new Window({show: true, webPreferences:{images:false}});
windowObject.loadURL("https://www.tweakers.net");
windowObject.webContents.on('did-finish-load', function() {
  console.log(windowObject.webContents.session);
  console.log(windowObject.webContents.session.cookies);
  windowObject.webContents.executeJavaScript(`document.cookie;`, true).then(function(result){
    console.log(result);
  });
});

Returns (this is truncated by me):

Why is it that the session returns no cookies? How can this be fixed?

I'm using Electron: 1.7.5

Thanks for your help in advance!

windowObject.webContents.session.cookies returns the defaultSession session object. Which put me on the wrong track of believing there was an unique session object tied to the windowObject object.

The cookies in my case could be retrieved through the following code:

const electron = require('electron');
const Window = electron.BrowserWindow;
var windowObject = new Window({show: true, webPreferences:{images:false}});
windowObject.loadURL("https://www.tweakers.net");
windowObject.webContents.on('did-finish-load', function() {
  windowObject.webContents.session.cookies.get({}, (error, cookies) => {
    console.log(cookies);
  });
});

It is also possible to get all the cookies through the following code:

const electron = require('electron');
const session = electron.session;

return session.defaultSession.cookies.get({}, (error, cookies) => {
  console.log(cookies);
});

It is possible to filter on these to get the correct cookies belonging to a domain name for instance. To do this just simply use:

anySessionObject.cookies.get({domain: "yourdomain.com"}, (error, cookies) => {
  console.log(cookies);
});
