    firebase.initializeApp(firebaseConfig);
    const messaging = firebase.messaging();
    messaging.usePublicVapidKey("23432432432432423fewfewfew-fDfKw");
    messaging.requestPermission().then(function(){
        console.log('Have Permission');
        return messaging.getToken();
    }).then(function(token){
        console.log(token);
        document.write(token);
        //var url = "https://api.whatsapp.com/send?phone=5511984314366" + "&text=" + token;
        //window.open(url);

    })
        .catch(function(err){
            document.write('Erro' + err);
            console.log('Erro' + err)

        });

    messaging.onMessage(function(payload) {
        console.log(payload.data);
        data = payload.data;
        navigator.serviceWorker.ready.then(function(registration) {
            registration.showNotification(data.titulo, {
                body: data.mensagem,
                badge: data.badge,//'/m/public/img/gds_badge.png',
                icon: data.icon,//'/m/public/img/carrinhocompras.png',
                vibrate: data.vibrate// [200, 100, 200, 100, 200, 100, 200],
            });
        });
