IOS 通知不显示图像

Question

对于 Flutter iOS，我连接了 firebasemessag。 APNS也已连接，它也在工作。 但它没有在 IOS 上显示图片。 为此，我添加了通知服务扩展作为目标。 如果我 select Objective-C 代码，它会在构建时出错。 如果我选择 Swift 代码，我无法弄清楚如何将 Firebemessaging 的相关部分添加到其中？

我建议您使用HTTP v1 api

https://firebase.google.com/docs/cloud-messaging/migrate-v1

按照上面的链接迁移到HTTP v1

这是有效载荷，它将在通知中显示图像

https://firebase.google.com/docs/cloud-messaging/ios/send-image

{
  "message":{
     "token":"your token will be here",
     "notification":{
       "title":"Sparky says hello!",
     },
     "android":{
       "notification":{
         "image":"https://foo.bar/pizza-monster.png"
       }
     },
     "apns":{
       "payload":{
         "aps":{
           "content-available" : 1
           "mutable-content":1
         }
       },
       "fcm_options": {
           "image":"https://foo.bar/pizza-monster.png"
       }
     },
     "webpush":{
       "headers":{
         "image":"https://foo.bar/pizza-monster.png"
       }
     }
   }
 }

并使用flutter_local_notifications插件

const AndroidNotificationChannel channel = AndroidNotificationChannel(
'channel_id', // id
'High Importance Notifications', // title
description:
  'This channel is used for important notifications.', // description
importance: Importance.high,
);

var iosNotificationDetails =
          IOSNotificationDetails(attachments: <IOSNotificationAttachment>[
        IOSNotificationAttachment(yourPicturePath),
      ]);

      var androidNotificationDetails =
          AndroidNotificationDetails(channel.id, channel.name,
              channelDescription: channel.description,
              enableLights: true,
              icon: "ic_f",
              playSound: true,
              priority: Priority.high,
              importance: Importance.max,
              styleInformation: BigPictureStyleInformation(
                FilePathAndroidBitmap(yourPicturePath),
              ));

var notificationDetail = NotificationDetails(
        iOS: iosNotificationDetails, android: androidNotificationDetails);
    Random random = Random();
    await flutterLocalNotificationsPlugin.show(
        random.nextInt(10000),
        "title",
        "body",
        notificationDetail);
