android - Ionic firebase token 始终为空且无 token 刷新

Question

我在过去 2 天遇到了 ionic firebase 模块 ( https://ionicframework.com/docs/native/firebase/) 的问题。

我不明白为什么我的 firebase token 在 app.component.ts 的以下代码部分中始终为 NULL:

this.platform.ready().then(() => {
  this.firebase.getToken().then(firebaseTokenSuccess).catch(firebaseTokenFailure);

  this.firebase.onTokenRefresh().subscribe(firebaseTokenRefresh);

  function firebaseTokenRefresh(tkn) {
    return alert("New token received: " + JSON.stringify(tkn));
  }

  function firebaseTokenSuccess(tkn) {
    return alert("Token access success: " + JSON.stringify(tkn));
  }

  function firebaseTokenFailure(e) {
    return alert("Token access failure: " + e.toString());
  }
});

如果我在就绪 block 的开头有 grantPermission()，我的 token 将变为空字符串

我运行了以下命令来安装我的插件:

$ ionic plugin rm cordova-plugin-firebase

$ npm install @ionic-native/push --save

这是我的插件列表:

$ ionic plugins                        
com.googlemaps.ios 2.4.0 "Google Maps SDK for iOS"
cordova-android-play-services-gradle-release 1.1.1 "cordova-android-play-services-gradle-release"
cordova-plugin-compat 1.2.0 "Compat"
cordova-plugin-console 1.1.0 "Console"
cordova-plugin-device 1.1.6 "Device"
cordova-plugin-facebook4 1.9.1 "Facebook Connect"
cordova-plugin-file 4.3.3 "File"
cordova-plugin-file-transfer 1.6.3 "File Transfer"
cordova-plugin-firebase 0.1.24 "Google Firebase Plugin"
cordova-plugin-googlemaps 1.4.5 "cordova-googlemaps-plugin"
cordova-plugin-inappbrowser 1.7.1 "InAppBrowser"
cordova-plugin-splashscreen 4.0.3 "Splashscreen"
cordova-plugin-statusbar 2.2.3 "StatusBar"
cordova-plugin-whitelist 1.3.2 "Whitelist"
ionic-plugin-keyboard 2.2.1 "Keyboard"

这是我的项目架构:

编辑:我添加了行 alert(JSON.stringify(this.firebase)) 这给了我以下字符串 {}

感谢阅读:)

编辑:

我发现它是最近的但在 firebase API 中。我不得不用 git repo 的 HEAD 更新我的包

Answer 1

try 是 ionic 2 中的代码

import { Platform } from 'ionic-angular';
import { Firebase } from '@ionic-native/firebase';

 constructor(public platform: Platform,private cordovaFirebase: Firebase)   {
  platform.ready().then(() => {
    StatusBar.styleDefault();
    Splashscreen.hide();
    this.cordovaFirebase.grantPermission();
    this.cordovaFirebase.getToken().then(token => {
       console.log("token....",token)
    }).catch(error => console.log(error)); 
  });
 }
