通知中与平台相关的问题

Question

当我使用ios模拟器发送通知时，我获得了所有设备令牌的所有成功响应。但是，当我使用模拟器发送通知时，我没有获得所有令牌的成功响应。

print("number of tokens ${getAllTokens.length}");
getAllTokens.forEach((dynamic i) async {


      String url = "https://fcm.googleapis.com/fcm/send";
      final msg = jsonEncode({
        "to": i,
        "notification": {
          "body": "Alarm turn On",
          "title": "FCM title",
          "sound": "default",
          "badge": "1"
        },
        "data": {
          "click_action": "FLUTTER_NOTIFICATION_CLICK",
        },
      });
      Map<String, String> headers = {
        'Content-Type': 'application/json',
        'authorization':
        'key=<server_key>'
      };
      return await http
          .post(url, body: msg, headers: headers)
          .then((http.Response responce) {
        final int statusCode = responce.statusCode;
        if (statusCode < 200 || statusCode > 400 || json == null) {
          print("%%%%%% ${responce.body}");
          throw new Exception("Error while fetching data");
        } else {
          print("success");
        }
      });
    });

使用仿真器测试结果：

flutter: number of tokens 16
flutter: success
flutter: success
flutter: success
flutter: success
flutter: success
flutter: success
flutter: success
flutter: success
flutter: success
flutter: success
flutter: success
flutter: success
flutter: success

使用仿真器测试结果：

I/flutter ( 5027): number of tokens 16
I/flutter ( 5027): success
I/chatty  ( 5027): uid=10123(com.example.rigato) 1.ui identical 13 lines
