Facebook Messenger PUSH notifications

FeZ

PREREQUISITES:

a FaceBook account;
a Messenger client installed on your device from appstore (Pesbuk recommended);
a "home" server capable running python3 code. You can run on your own UPBorts device instead, but I have not tested;
"pushclient" mini app installed on your device from AppStore;
basic programming skills;
understanding, and taking your own responsibility of security considerations.

GETTING YOUR APP TOKEN

Start your pushclient on the UB device.
Write/copy your token (take care, it's yours, don't share with others!)

INSTALL fbchat

Login as administrator (aka. root) to your home server
install fbchat:

# pip install fbchat

INSTALL AND SETUP fbnotifications.py

Login as a safe normal user to your home server.
Open your favourite code editor, and create a file 'fbnotifications.py'. Copy this code into that file:

#!/usr/bin/env python

import signal
import sys
import requests
import json
from datetime import datetime, timedelta

from fbchat import Client
from fbchat.models import *

DEBUG = True
LOG_FILENAME = "debug.log"

USER = "<your facebook login email>"
PASSWORD = "<your facebook login password>"

PUSH_URL = "https://push.ubports.com/notify"
HEADERS = {"Content-Type" : "application/json"}

card = {
    "icon" : "message",
    "body" : "",
    "summary" : "Messenger",
    "popup" : True,
    "persist" : True
}

notification = {
    "card" : card,
    "vibrate" : True,
    "sound"   : True
    }

data = {
    "notification" : notification,
    }

params = {
    "appid" : "pushclient.christianpauly_pushclient",
    "token" : "<your ubuntu one app token>",
    "expire_on" : "",
    "data" : data
}


client = None
logfile = None

def log(log_msg):
    if DEBUG:
        logfile.write(f'{str(log_msg)}\n')
        logfile.flush()
def signal_handler(sig, frame):
    log('Exiting with signal {sig}')
    if client and client.isLoggedIn():
        client.logout()
    if logfile:
        logfile.close()
    sys.exit(0)


class CustomClient(Client):
    def onMessage(self, mid, author_id, message_object, thread_id, thread_type, ts, metadata, msg, **kwargs):
        if not DEBUG and author_id == self.uid:
            return
        
        user = self.fetchUserInfo(author_id)[author_id]
        log(f'Message from:\n{str(user)}\n')
        name = 'noname'
        if user.nickname:
            name = user.nickname
        elif user.name:
            name = user.name
        
        dt = datetime.now() + timedelta(days=1)
        dt_str = dt.strftime("%Y-%m-%dT%H:%M:00.000Z")
        if message_object:
            if message_object.text:
                body = f'{name}: {message_object.text[:23]}'
            else:
                body = f'{name} sent media content.'
            params["expire_on"] = dt_str
            params["data"]["notification"]["card"]["body"] = body
            json_data = json.dumps(params)
            log(f'Data sent:\n {json_data}\n')
            r = requests.post(url=PUSH_URL, headers=HEADERS, data=json_data)
            log(r.json())

if __name__ == "__main__":

    if DEBUG:
        print(f'Loggin in: {LOG_FILENAME}')
        logfile = open(LOG_FILENAME, "a")

    client = CustomClient(USER, PASSWORD)

    log(f'User logged in: {client.isLoggedIn()}')
    log(client.getSession())

    signal.signal(signal.SIGINT, signal_handler)

    client.listen()

Change <your facebook login email>, <your facebook login password>, and <your ubuntu one app token> strings to your own data respectively.
Set DEBUG global variable according to your needs to False or True.
Save the file.
Set permissions so that only you (and administrator) can read your personal data:

$ chmod 600 fbnotifications.py

Run the program:

$ python fbnotifications.py

TESTING
If you want to run a self-test, then:

set DEBUG = True, and see the generated logfile in another terminal;
open FB Messenger web client in a desktop browser;
search for yourself in the search box above the contact list;
send a message to yourself;

Now you have to wait until the push notification arrives.
If you have issues, write me on telegram UBPorts Supergroup.

POSSIBLE OPTIONS

Run the program on home server as a system service (recommended).

on most modern Linux use systemd
on BSD use rc scripts

Run the program in a screen process

This is a very simple solution to run it quick and "service" like.
Note, this will not start automatically after a system restart.

DEFICIENCIES

Tapping the notification does not open the Messenger app automatically. You have to open it explicitly.

Wow this sounds interesting. Sadly I don't have my own server.

Another alternative though is using the Pesbuk app. It's just a webapp but if you set it to run in the background (via UTTT) it'll get push notifications whenever you get new ones. There's a know issue though when you have a different webapp header than the one tested with it.

I'm not intentionally promoting my app. Just trying to help

FeZ

Thank you, I'll try that also.
