Hi all,
I am now testing Venom-bot for WhatsApp and was really easy to setup. Of course there might be some Cons but as this is just a learning curve and testing might be worth sharing…
NodeJs Server
const express = require(‘express’);
const app = express();
const http = require(‘http’);
const server = http.createServer(app);
//const { Server } = require(“socket.io”); Was trying to use for message exchange between Nodejs and Frappe
const io = new Server(server);
const path = require(‘path’);
const porta = 4400;
const venom = require(‘venom-bot’);
app.get(‘/api/whatsapp-web’, whatsappweb_url);
function whatsappweb_url(request, response, next) {
console.log(request.params);
console.log(__dirname);
response.sendFile(path.join(__dirname+‘/whazapp.html’));
venom
.create(
'sessionName',
(base64Qr, asciiQR) => {
console.log(asciiQR); // Optional to log the QR in the terminal
var matches = base64Qr.match(/^data:([A-Za-z-+\/]+);base64,(.+)$/),
response = {};
if (matches.length !== 3) {
return new Error('Invalid input string');
}
response.type = matches[1];
response.data = new Buffer.from(matches[2], 'base64');
var imageBuffer = response;
require('fs').writeFile(
'out.png',
imageBuffer['data'],
'binary',
function (err) {
if (err != null) {
console.log(err);
}
}
);
},
// statusFind
(statusSession, session) => {
console.log('Status Session: ', statusSession); //return isLogged || notLogged || browserClose || qrReadSuccess || qrReadFail || autocloseCalled || desconnectedMobile || deleteToken
//Create session wss return "serverClose" case server for close
console.log('Session name: ', session);
if (statusSession == "notLogged"){
//To QRCode page
console.log('statusSession');
io.sockets.emit('message', "NAO ESTA LIGADO!");
}
},
undefined,
{ logQR: false }
)
.then((client) => {
start(client);
})
.catch((erro) => {
console.log(erro);
});
async function start(client) {
client.onMessage(async (message) => {
if (message.body === 'Hi' && message.isGroupMsg === false) {
client
.sendText(message.from, 'Welcome Venom 🕷')
.then((result) => {
console.log('Result: ', result); //retorna o object com successo
})
.catch((erro) => {
console.error('Error when sending: ', erro); //retorna o object error
});
} else if (message.body === '!factura' && message.isGroupMsg === false){
console.log('Enviar Factura PDF... ', "/home/frappe/frappe-bench/" + pastapublico + 'FT-21-2.pdf');
await client.sendFile(message.from,"/home/frappe/frappe-bench/" + pastapublico + 'FT-21-2.pdf');
}
});
client.onStateChange((state) => {
console.log('Status');
console.log(state);
if (state == "CONNECTED"){
io.emit('chat message', 'Cliente esta pronto para enviar Mensagens!');
} else if (state == "DISCONNECTED"){
io.emit('chat message', 'Cliente Desligado!');
}
});
server.listen(porta, () => {
console.log(listening on *:${porta});
});
