IONIC 3:在iOS中，onNotification不会在前台触发吗? [英] IONIC 3: onNotification not fire in foreground in IOS?

问题描述

我已经在ionic中实现了推送通知，一切在android上都可以正常运行，但是在IOS中却遇到了不同的情况:

I have implemented push notification in ionic Everything working fine on android and but in IOS got different scenario:

1. 前景:不会触发onNotification以及android正常工作.
2. 背景:收到推送通知，但是从通知中轻按后没有任何反应

app.component.ts

this.fcm.onNotification().subscribe(data => {
if(data.wasTapped){
  console.log(data.wasTapped);
     //redirectPageViaNotificationType for redirect page...
     this.redirectPageViaNotificationType(data);
}  else {
    //Notification was received in foreground. Maybe the user needs to be notified
      // if application open, show
    let confirmAlert = this.alertCtrl.create({
      title: (<any>data).title,
      message: (<any>data).body,
      buttons: [{
        text: 'Ignore',
        role: 'cancel'
      },{
        text: 'View',
        handler: () => {
            //redirectPageViaNotificationType for redirect page...
          this.redirectPageViaNotificationType(data);
        }
      }]
    });
    confirmAlert.present();
}
});

当收到任何推送通知时，当我的应用程序关闭或后台运行时，它的显示通知均不执行this.fcm.onNotification()函数.我只是调试了这个问题，并在xcode控制台中注意到了这一点:

when any push notification is received its showing notification when my application is closed or background it does not executing the this.fcm.onNotification()function. And i just debug this issue and noticed this, in my xcode console its showing:

尝试过的解决方案

1. 在通知有效负载中添加"content_available":true ，但不适用于我.

删除以下插件:

npm i cordova-plugin-fcm-with-dependecy-updated和local-notification插件，然后再次添加但对我不起作用.

npm i cordova-plugin-fcm-with-dependecy-updated and local-notification plugin and add it again but not worked for me.

任何人都可以告诉我为什么会出现问题以及出了什么问题吗?

can any one please tell me why its happing and what's going wrong?

推荐答案

如果要处理请求，即不仅要像使用content-available: '1'那样在后台处理某些数据，还必须将其保留为content-available: '0'

If you want to handle the requests, ie not just process some data in the background as you would with content-available: '1', you must leave it as content-available: '0'.

我使用PHP和Kreait/Firebase处理推式通知.然后对于iOS，这是我的配置:

I process Push notifications with PHP and Kreait/Firebase. Then for iOS this is my config:

  $notification = Notification::fromArray([
    'title' => $title,
    'body'  => $message,
  ]);

  $data = MessageData::fromArray([
    'some_key' => $value,
  ]);

  $apnsConfig = ApnsConfig::fromArray([
    'payload' => [
      'aps' => [
        'badge' => 1,
        'content-available' => 0,
        'notId' => UUID::v4()
      ],
    ],
  ]);

  $cloudMessage = CloudMessage::new()
    ->withNotification($notification)
    ->withData($data)
    ->withApnsConfig($apnsConfig);

  $apnsResult = self::$messaging->sendMulticast($cloudMessage, $iosTokens);

您可以在此处找到文档: https://firebase.google.com/docs/云消息.对于Android，我使用curl，但是那时kreaits的fcm实现存在一些问题.他们确实发布了我要检查的新版本，以检查它是否已解决此问题.

You can find the documentation here: https://firebase.google.com/docs/cloud-messaging. For Android I used curl however, there was some problem back then with kreaits' fcm implementation. They did publish a new release that I ment to check whether it fixed this.

希望这会有所帮助.
