cordova-plugin-fcm - 未定义 FCMPlugin

Question

我正在使用 Ionic 2，并且正在尝试让推送通知正常工作。

我已经在 Firebase 中注册了我的应用，并且可以成功向其推送通知。

我现在需要进行设置，以便可以从我的应用推送通知。所以我决定使用下面的 Cordova 插件 (cordova-plugin-fcm)。

问题 1

当我按照它的说明操作时，在我的 Ionic 应用程序中执行以下操作：

app.ts

declare var FCMPlugin;
...

  initializeApp() {
    this.platform.ready().then(() => {
...
    FCMPlugin.getToken(
      function (token) {
....

我在运行时收到以下错误：

异常：错误：未捕获（承诺中）：ReferenceError：FCMPlugin 是 未定义

请问我该如何解决？

问题 2

为了从您的应用发送通知，Cordova 插件 (cordova-plugin-fcm) 指示以下内容：

//POST: https://fcm.googleapis.com/fcm/send 
//HEADER: Content-Type: application/json 
//HEADER: Authorization: key=AIzaSy******************* 
{
  "notification":{
    "title":"Notification title",  //Any value 
    "body":"Notification body",  //Any value 
    "sound":"default", //If you want notification sound 
    "click_action":"FCM_PLUGIN_ACTIVITY",  //Must be present for Android 
    "icon":"fcm_push_icon"  //White icon Android resource 
  },
  "data":{
    "param1":"value1",  //Any data to be retrieved in the notification callback 
    "param2":"value2"
  },
    "to":"/topics/topicExample", //Topic or single device 
    "priority":"high", //If not set, notification won't be delivered on completely closed iOS app 
    "restricted_package_name":"" //Optional. Set for application filtering 
}

这甚至不是 Typescript 或 Javascript。那么它要去哪里呢？我只是不明白。任何建议表示赞赏。

您的 HTML 索引文件中应该包含 FCMPlugin.js 在应用程序的插件目录中找到 js 文件的路径 示例：MyFCM\plugins\cordova-plugin-fcm\www\FCMPlugin.js

app.controller('AppCtrl', function(FCMPlugin,$scope,$cordovaToast,$cordovaDialogs,ionPlatform) {
  // call to register automatically upon device ready
  ionPlatform.ready.then(function (device) {
    console.log('I am working');
    FCMPlugin.onNotification(
      function(data){
        if(data.wasTapped){
          //Notification was received on device tray and tapped by the user.
          $cordovaDialogs.alert(data.notification.body);
        }else{
          //Notification was received in foreground. Maybe the user needs to be notified.
          $cordovaDialogs.alert(data.notification.body);
          //$cordovaToast.showShortCenter( JSON.stringify(data) );
        }
      },
      function(msg){
        $cordovaToast.showShortCenter('onNotification callback successfully registered: ' + msg);
      },
      function(err){
        $cordovaToast.showShortCenter('Error registering onNotification callback: ' + err);
      }
    );
  });
})
