Flutter ios设备不会从FCM通知中触发onMessage实施APN时Sendtodevice失败

问题描述

在我的fcm云功能中，它可以向其他播放器发送通知，但是当我添加apns图层时，它无法发送。删除apns层后，通知会显示在android上，但对于iOS，通知是在前端接收的，但无法触发onMessage函数来显示警报对话框。

 var payload = {
        data: {
            click_action: "FlutteR_NOTIFICATION_CLICK",notificationType: "friendsRequest",fromUsername: fromUsername,fromProfilePic: fromProfilePic,fromColorIndex: fromColorIndex,type: type
        },};

此有效负载返回服务器响应“崩溃”

解决方法

要为iOS启用通知，您需要先为iOS设置FCM： 如您所说，您已经生成了APN。只需确认您是否已将apn与firebase项目链接。之后，在Xcode中打开您的项目ios模块，并在AppDelegate中进行以下更改

if #available(iOS 10.0,*) {
  UNUserNotificationCenter.current().delegate = self as? 
  UNUserNotificationCenterDelegate
}

在颤动侧进行更改（我在启动屏幕中使用此代码）：

初始化

FirebaseMessaging _firebaseMessaging = FirebaseMessaging();
FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin = new FlutterLocalNotificationsPlugin();

initState（）中的代码

var initializationSettingsAndroid =
    new AndroidInitializationSettings('@mipmap/ic_launcher'); //replace with your app icon file
var initializationSettingsIOS = new IOSInitializationSettings();
var initializationSettings = new InitializationSettings(
    initializationSettingsAndroid,initializationSettingsIOS);
flutterLocalNotificationsPlugin.initialize(initializationSettings,onSelectNotification: onSelectNotification);

FirebaseNotifications().setUpFirebase(_firebaseMessaging);
_firebaseMessaging.configure(
  onMessage: (Map<String,dynamic> message) async {
    showNotification(
        message['notification']['title'],message['notification']['body']);
    print("onMessage: $message");
  },onLaunch: (Map<String,dynamic> message) async {
    print("onLaunch: $message");
  },onResume: (Map<String,dynamic> message) async {
    print("onResume: $message");
  },);

通知方法：

void showNotification(String title,String body) async {
   await _demoNotification(title,body);
}

Future<void> _demoNotification(String title,String body) async {
  var androidPlatformChannelSpecifics = AndroidNotificationDetails(
     'channel_ID','channel name','channel description',importance: Importance.Max,playSound: true,sound: 'sound',showProgress: true,icon: 'notification_icon',color: AppTheme.secondaryaccent,priority: Priority.High,ticker: 'test ticker');

 var iOSChannelSpecifics = IOSNotificationDetails();
 var platformChannelSpecifics = NotificationDetails(
     androidPlatformChannelSpecifics,iOSChannelSpecifics);
  await flutterLocalNotificationsPlugin
    .show(0,title,body,platformChannelSpecifics,payload: 'test');
 }
