如何为推送通知添加分析

Question

我正在开发渐进式网络应用程序,我想为推送通知实施分析.

如何为推送通知添加分析,以便我能够跟踪和记录有多少人点击通知以及有多少人关闭该通知而不点击它.

我编写了一小部分代码来使用Google分析进行分析,它运行得相当好.

这里有简要说明:https://gauntface.com/blog/2016/05/01/push-debugging-analytics

我这样做的方式是上面提到的帖子:

在服务工作者中,我导入了一个javascript文件,为我做跟踪,设置分析ID,然后在适当的事件中调用跟踪.寻找self.analytics.trackEvent:

importScripts('./scripts/analytics.js');

self.analytics.trackingId = 'UA-77119321-2';

self.addEventListener('push', function(event) {
  let notificationTitle = 'Hello';
  const notificationOptions = {
    body: 'Thanks for sending this push msg.',
    icon: './images/icon-192x192.png',
    tag: 'simple-push-demo-notification'
  };

  // Important to trigger analytics asynchronously with logic
  // to show notification
  event.waitUntil(
    Promise.all([
      self.analytics.trackEvent('push-received'),
      self.registration.showNotification('Hello', notificationOptions)
    ])
  );
});

self.addEventListener('notificationclick', function(event) {
  event.notification.close();

  // Important to trigger analytics asynchronously with logic
  // to do other work (i.e. open window)
  event.waitUntil(
    Promise.all([
      self.analytics.trackEvent('notification-click'),
      clients.openWindow('https://gauntface.github.io/simple-push-demo/')
    ])
  );
});

下面显示了对Google Analytics测量协议进行实际跟踪调用的代码.API非常简单,因此payloadData是分析期望的属性,我以API期望的格式生成这些参数的字符串,过滤掉空/空值:

class Analytics {
  trackEvent(eventAction, eventValue) {
    if (!this.trackingId) {
      console.error('You need to set a trackingId, for example:');
      console.error('self.analytics.trackingId = \'UA-XXXXXXXX-X\';');

      // We want this to be a safe method, so avoid throwing Unless
      // It's absolutely necessary.
      return Promise.resolve();
    }

    if (!eventAction && !eventValue) {
      console.warn('sendAnalyticsEvent() called with no eventAction or ' +
      'eventValue.');
      return Promise.resolve();
    }

    return self.registration.pushManager.getSubscription()
    .then(subscription => {
      if (subscription === null) {
        // The user has not subscribed yet.
        throw new Error('No subscription currently available.');
      }

      const payloadData = {
        // GA Version Number
        v: 1,
        // Client ID
        cid: subscription.endpoint,
        // Tracking ID
        tid: this.trackingId,
        // Hit Type
        t: 'event',
        // Data Source
        ds: 'serviceworker',
        // Event Category
        ec: 'serviceworker',
        // Event Action
        ea: eventAction,
        // Event Value
        ev: eventValue
      };

      const payloadString = Object.keys(payloadData)
      .filter(analyticsKey => {
        return payloadData[analyticsKey];
      })
      .map(analyticsKey => {
        return `${analyticsKey}=` +
          encodeURIComponent(payloadData[analyticsKey]);
      })
      .join('&');

      return fetch('https://www.google-analytics.com/collect', {
        method: 'post',
        body: payloadString
      });
    })
    .then(response => {
      if (!response.ok) {
        return response.text()
        .then(responseText => {
          throw new Error(
            `Bad response from Google Analytics ` +
            `[${response.status}] ${responseText}`);
        });
      }
    })
    .catch(err => {
      console.warn('Unable to send the analytics event', err);
    });
  }
}

if (typeof self !== 'undefined') {
  self.analytics = new Analytics();
}
