单击Web推送通知时打开自定义URL

我正在实施Webpush ruby gem向我网站的用户发送推送通知。

服务器代码:

self.addEventListener("push", function (event) {
  var title = (event.data && event.data.text()) || "New Message";

  event.waitUntil(
    self.registration.showNotification(title, {
      body: "New push notification",
      icon: "/images/logo@2x.png",
      tag:  "push-notification-tag",
      data: {
        url: event.data.url, // This is returning null
        id: event.data.id // And this is returning null
      }
    })
  )
});

self.addEventListener('notificationclick', function(event) {
  event.notification.close();
  event.waitUntil(
    clients.openWindow(event.data.url + "?notification_id=" + event.data.id)
  );
})

我在客户端设置了一个服务工作者来显示通知并使其可以点击。

url

一切正常,但我通过的自定义键(idwhere title >= '0' and title < ':' )无法从服务工作者中访问。

有谁知道如何通过WebPush gem传递自定义数据?

自定义数据位于 event.notification 对象中,不在事件中直接(在 notificationclick 中)。因此,如果您想在notificationclick函数中获取自定义数据变量,那么您应该这样做:)

self.addEventListener('notificationclick', function(event) {
  event.notification.close();
  event.waitUntil(
    clients.openWindow(event.notification.data.url + "?notification_id=" + event.notification.data.id)
  );
})

Webpush (with a payload) documentation开始,您似乎应该使用JSON.stringify()方法将所有数据放入邮件中,然后使用JSON.parse()在服务工作者中检索它。

服务器:

Webpush.payload_send({
  message:JSON.stringify({
    message: notification.message,
    url: notification.url,
    id: notification.id,
  }),
  endpoint: endpoint,
  p256dh: p256dh_key,
  vapid: vapid_keys,
  ttl: 24 * 60 * 60,
  auth: auth_key,
})

客户端:

 event.waitUntil(
   self.registration.showNotification(title, {
   body: "New push notification",
   icon: "/images/logo@2x.png",
   tag:  "push-notification-tag",
   data: {
     url: JSON.parse(event.message).url
   }
})

将此添加到您的Angular项目中的node_modules/@angular/service-worker/ngsw-worker.js

this.scope.addEventListener('notificationclick', (event) => {
            console.log('[Service Worker] Notification click Received. event:%s', event);
            event.notification.close();
            if (clients.openWindow && event.notification.data.url) {
                event.waitUntil(clients.openWindow(event.notification.data.url));
            }
        });

您可以输入上面的代码,在文件中的此行

this.scope.addEventListener('notificationclick', (event) => ..

您必须再次构建dist才能使其正常工作。在后端,您将需要使用以下格式:

{"notification":{"body":"This is a message.","title":"PUSH MESSAGE","vibrate":[300,100,400,100,400,100,400],"icon":"https://upload.wikimedia.org/wikipedia/en/thumb/3/34/AlthepalHappyface.svg/256px-AlthepalHappyface.svg.png","tag":"push demo","requireInteraction":true,"renotify":true,"data":{"url":"https://maps.google.com"}}}

您可以在网址内输入网址,点击通知后,您的推送通知将打开给定的链接并将其聚焦在浏览器中

对于Webpush Ruby Gem,经过一些修改,这对我有用:

Webpush.payload_send(
  endpoint: user.push_subscription.endpoint,
  message: {
    message: "A new service request is created",
    id: service_request.request_number,
    url: "https://google.com/"
  }.to_json,
  p256dh: user.push_subscription.key,
  auth: user.push_subscription.auth_key,
  ttl: 24 * 60 * 60,
  vapid: {
    subject: 'A Push Notification',
    public_key: ENV['VAPID_PUBLIC_KEY'],
    private_key: ENV['VAPID_PRIVATE_KEY']
  }
)

位置:

  • user.push_subscription.endpointPushSubscription模型中定义的用于返回端点的方法
  • user.push_subscription.key, user.push_subscription.auth_key还是在同一模型中定义的方法

/serviceworker.js.erb

self.addEventListener("push", (event) => {
  let response = event.data && event.data.text();
  let title = JSON.parse(response).message;
  let body = JSON.parse(response).id;
  let icon = '/assets/logo-blue-120x120.jpg';

  event.waitUntil(
    self.registration.showNotification(title, { body, icon, data: { url: JSON.parse(response).url } })
  )
});

self.addEventListener('notificationclick', function(event) {
  event.notification.close();
  event.waitUntil(
    clients.openWindow(event.notification.data.url)
  );
});
