Question

我有一个使用Polymer 2.0和firebase的PWA应用程序。 Firebase消息传递错误。

 Firebase v3.18.4
 "polymer": "Polymer/polymer#^2.0.0",
 "webcomponentsjs": "webcomponents/webcomponentsjs#^1.0.0",
 "polymerfire": "firebase/polymerfire#^2.2.0",

消息传递在Chrome桌面中无效 - [Google Chrome是最新的版本66.0.3359.139（官方构建）（64位）]以及Chrome Android - [应用程序版本Chrome 66.0.3359.126

使用的代码

my-app.html（PolymerElement）

<script src="bower_components/firebase/firebase-app.js"></script>
<script src="bower_components/firebase/firebase-auth.js"></script>
<script src="bower_components/firebase/firebase-database.js">      
 </script>
 <script src="bower_components/firebase/firebase-firestore.js">  
 </script>
 <script src="bower_components/firebase/firebase-messaging.js">   
 </script>
 <script src="bower_components/firebase/firebase-storage.js"> 
 </script>

  <firebase-app
    auth-domain="[[configFirebase.authDomain]]"
    database-url="[[configFirebase.databaseURL]]"
    api-key="[[configFirebase.apiKey]]"
    storage-bucket="[[configFirebase.storageBucket]]"
    messaging-sender-id="[[configFirebase.messagingSenderId]]">
  </firebase-app>

  <firebase-auth
    id="auth"
    user="{{user}}"
    signed-in="{{signedIn}}"
    status-known="{{statusKnown}}"
    on-error="_handleError">
  </firebase-auth>

  <firebase-messaging
        id="messaging"
        token="{{token}}"
        on-message="handleMessage"
        active="{{fcmActive}}"
        status-known="{{fcmStatusKnown}}">
  </firebase-messaging>

   <firebase-document path="/users/[[user.uid]]/token" data=". 
    {{tokenDocVal}}">
   </firebase-document>

  class MyApp extends Polymer.Element {
       static get is() { return 'my-app'; }

    ready() {
      this.addEventListener('request-fcm-permission',        
         this._requestFcmPermission);
      super.ready();
    }

   _requestFcmPermission() {
      var fcm = this.$.messaging;
      var self = this;
      if (this.user && !fcm.active) {
        fcm.requestPermission()
          .then(function(){
            console.log('FCM permission granted');
            console.log('[[token]] ->' + self.token);
            self.tokenDocVal = self.token;
          })
          .catch(function(e){
            console.warn('FCM permission blocked', e);
          })
      }
    }

    ... other html code ....

而且 firebase-messaging-sw.js

    importScripts('/bower_components/firebase/firebase-app.js');
    importScripts('/bower_components/firebase/firebase-
       messaging.js');

   firebase.initializeApp({
    'messagingSenderId': '<project-ms-id>'
   });

   var messaging = firebase.messaging();

   messaging.setBackgroundMessageHandler(function(payload) {
   console.log('[firebase-messaging-sw.js] Received background 
     message 
      ', payload);

   var notificationTitle = payload.notification.title;
   var notificationOptions = {
   body: payload.notification.body,
   icon: '../images/fresh/android/android-launchericon-24-24.png'
    };
   return self.registration.showNotification(notificationTitle,
    notificationOptions);
   });

   Manifest.json includes "gcm_sender_id": "103953800507",

请求帮助以解决此问题。我已经讨论过这个问题很久了，不知道为什么会发生这种情况以及如何解决它。

我还在GITHUB上添加了关于这个问题的评论 https://github.com/firebase/firebase-js-sdk/issues/152
