推送通知链接onclick在FCM中给出未定义

Question

我正在使用fcm发送推送通知。 我的有效负载就是这个，我可以在console.log中看到它，但是这些url值始终是不确定的。

这是完整的有效负载，这是serviceworker.js

有效载荷

  {title: "test", body: "This is the body content", icon: "https://png.pngtree.com/element_origin_min_pic/16/08/05/1057a3fae73b91b.jpg", image: "https://png.pngtree.com/element_origin_min_pic/16/08/05/1057a3fae73b91b.jpg", badge: "https://cdn.iconscout.com/icon/free/png-128/love-r…antic-valentine-valentines-day-heart-10-24261.png", …}badge: "https://cdn.iconscout.com/icon/free/png-128/love-romance-romantic-valentine-valentines-day-heart-10-24261.png"body: "This is the body content"icon: "https://png.pngtree.com/element_origin_min_pic/16/08/05/1057a3fae73b91b.jpg"image: "https://png.pngtree.com/element_origin_min_pic/16/08/05/1057a3fae73b91b.jpg"title: "chutiyaaaaaa"url: "https://ndtv.com/7877"

serviceworker.js

self.addEventListener('push', function (event) {
    if (!(self.Notification && self.Notification.permission === 'granted')) {
        return;
    }

 const sendNotification = body => {
        // you could refresh a notification badge here with postMessage API
 const title = "Web Push example";
      //  const title = "Web Push example";
  const options999999 = {
    icon: 'https://png.pngtree.com/element_origin_min_pic/16/08/05/1057a3fae73b91b.jpg',
    vibrate: [100, 50, 100],
    data: {
      dateOfArrival: Date.now(),
      primaryKey: 1
    },
    actions: [
      {action: 'explore', title: 'Explore this new world',
        icon: 'images/checkmark.png'},
      {action: 'close', title: 'I don\'t want any of this',
        icon: 'https://png.pngtree.com/element_origin_min_pic/16/08/05/1057a3fae73b91b.jpg'}
    ]  

     };       

         return self.registration.showNotification(title, {

            body,
        });
    };  



    if (event.data) {
var payload = event.data.json();
var title = payload.title;
 var body  = payload.body;
var bigimg = payload.image;
var badgee = payload.badge;
var url = payload.url;
var icon  = payload.icon;

    console.log(payload); 


event.waitUntil(self.registration.showNotification(title, {
body: body,
icon: icon,
image: bigimg,
badge: badgee,
data: {
     url: url
},
data: {} // Keeping this here in case I need it later
}

));


    }



});


self.onnotificationclick = function(event) {
    var url99 = '';

    const notificationpp = event.notification;
  const primaryKey = notificationpp.data.url;
    const notificationpp999 = event.notification.data;


event.notification.close();

 let clickResponsePromise = Promise.resolve();
  if (event.notification.data && event.notification.data.url) {
    clickResponsePromise = clients.openWindow(event.notification.data.url);
  }

event.waitUntil(
clients.matchAll({
type: 'window'
})


.then(function() {
if (clients.openWindow) {

var payload22 = event.notification.data.url;

 url99 = event.notification.data.url; 

    console.log(payload22);   // why undefined ?? 

return clients.openWindow(payload22); // open it
}
})
);
};

问题出在哪里？当我单击通知时，它始终显示未定义，但是我通过了正确的参数器
