我正在我的网站上开发网络推送通知.我关注了Google的Web Push Notifications和Mozilla的The Service Worker Cookbook.

我已经在Google Chrome v50上进行了测试,一切正常,但在调用navigator.serviceWorker.register(‘./时,我会在Firefox 44,45,46,52,最新的Firefox(版本57.0.4 64位)上收到以下错误消息. push-service-worker.js’)函数.

TypeError: ServiceWorker script at 07002 for scope 07003 encountered an error during installation.

这是我的代码：

在controller.js中注册ServiceWorker

navigator.serviceWorker.register('push-service-worker.js')
.then((registration) => {
  return registration.pushManager.getSubscription()
    .then((subscription) => {
      if (subscription) {
        return subscription;
      }
      var subscribeOptions = {
        userVisibleOnly: true,applicationServerKey: buildApplicationServerKey(),};
      return registration.pushManager.subscribe(subscribeOptions);
    });
})
.then((subscription) => {
  sendSubscriptionToServer(subscription);
})
.catch((err) => {
  console.log('Unable to subscribe to push: ',err);
});

推送服务worker.js

'use strict';

self.addEventListener('push',(event) => {
  var payload = event.data.json();
  var title = payload.title || 'Title';
  event.waitUntil(
    self.registration.showNotification(title,{
      body: payload.body,icon: './common/images/notification-icon-192x192.png',image: payload.image || '',})
  );
});

self.addEventListener('notificationclick',(event) => {
  event.notification.close();
  var urlToOpen = new URL('/',self.location.origin).href;
  event.waitUntil(
    clients.matchAll({
      type: 'window',includeUncontrolled: true,})
      .then((windowClients) => {
        var matchingClient = null;
        for (var i = 0; i < windowClients.length; i++) {
          var windowClient = windowClients[i];
          if (windowClient.url === urlToOpen) {
            matchingClient = windowClient;
            break;
          }
        }

        if (matchingClient) {
          return matchingClient.focus();
        } else {
          return clients.openWindow(urlToOpen);
        }
      })
  );
});
