Restore session

[jovazxc-zz]

I'm trying to restore the WhatsApp Session, I found that most of data is saved in the localStorage and a little part is on cookies

I obtained the cookies using the dev tools functions because there are HttpOnly, and it can't be obtained through normal methods

async cookies() {
    const client = await this.pupPage.target().createCDPSession();
    let r = await client.send('Network.getAllCookies');
    return r.cookies;
}

But I'm unable to apply them, I'd tried with

page.setCookie()

But isn't working

I've done, but restore isn't working headless, waitforselector never get resolved

Clone my repo https://github.com/jovazxc/whatsapp-web.js/ and try the following

First npm install

• Modify example.js and set headless to true
• node example.js
• Scan QR code on terminal (You have to set terminal to full size first)
• Close (Ctrl c)
• node example.js
• Waiting for auth never is solved
• Close
• Modify headless to false
• node example.js

Thanks for the input!

The main issue here with using localStorage is that there's something in WhatsApp Web's code that prevents us from going to the application more than once while in headless mode. Just doing a simple refresh on the page won't let you get in, showing you the following error:

This means that we would need to apply the tokens to localStorage using some other method. I was able to do this using puppeteer's evaluateOnNewDocument function that runs before any other scripts do. Restoring sessions should now work. I've added this in a7a7034.

To restore the session just pass a "session" parameter to the options object like so:

const client = new Client({session: {
    WABrowserId: "",
    WASecretBundle: "",
    WAToken1: "",
    WAToken2: ""
}});

The authenticated event now also returns the session object via its single param:

client.on('authenticated', (session) => {
    // session param contains object structured as above
});

I have a question here, how long can we stay in one session? My client have responded during the 2 days and then there was 'Client was logged out' @jovazxc @pedroslopez

I'm not entirely sure, to be honest... However, make sure you don't log in to WhatsApp Web for that number on another app or browser as that will log it out. If connection to the phone is lost, this will also trigger a disconnect event. Ideally this case should be a bit more resilient so if it is indeed because connection was temporarily lost, then it should recognize when it's back online instead of just emitting the disconnect event and closing the client.

Hello,

How to store session and use it? I had put on session.json like this :
{"WABrowserId" : 1 ,"WASecretBundle" : "test" ,"WAToken1" : "a1","WAToken1" : "a2"}

and this my scan code :

const qrcode = require('qrcode-terminal');

const { Client } = require('whatsapp-web.js');
const fs = require('fs');

const SESSION_FILE_PATH = './session.json';
let sessionCfg;
if (fs.existsSync(SESSION_FILE_PATH)) 
{
    sessionCfg = require(SESSION_FILE_PATH);
}

const client = new Client({ session: sessionCfg });

client.on('qr', qr => {
    qrcode.generate(qr, {small: true});
});

client.on('ready', () => {
    console.log('Client is ready!');
});
client.initialize();`=

It doesn't work, is there something wrong on my code?

please help me, thanks.

Hi @gunomnifluencer, you're not saving the session info on successful login. Specifically, you're missing the authenticated event.

For more info, please read https://waguide.pedroslopez.me/features/resuming-sessions

[TLGits]

how to check if the client is logged in successfully?

I follow the https://waguide.pedroslopez.me/features/resuming-sessions, but it does not trigger the 'authenticated'.
