点击FCM通知消息时，如何获取消息正文

Question

当应用在后台时，通知消息通过notification发送，当通知被点击，应用启动时，如何获取消息正文?

意图是:

    Bundle[{google.sent_time=1470813025421, from=568540028909, 
google.message_id=0:1470813025865549%31bd1c9631bd1c96,
 collapse_key=com.google.firebase.quickstart.fcm}]

intent中没有消息正文，只有消息id!谢谢!

Answer 1

try this

  @Override
        public void onMessageReceived(RemoteMessage remoteMessage) {
            // TODO(developer): Handle FCM messages here.
            // If the application is in the foreground handle both data and notification messages here.
            // Also if you intend on generating your own notifications as a result of a received FCM
            // message, here is where that should be initiated. See sendNotification method below.
            Log.d(TAG, "From: " + remoteMessage.getFrom());
            Log.d(TAG, "From: " + remoteMessage.getData().get("message"));
    //        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
// if you sending data with custom key
 Log.d(TAG, "Notification Message of custom key: " +remoteMessage.getData().get("your key"));
            sendNotification(remoteMessage.getData().get("message"));
        }

很抱歉，你想做的是不可能的。

目前无法访问
的(body, title, icon…)信息。通知打开时启动的活动的notification-message

您可以访问通知消息的data组件。

一个可能的替代方案是使用data-message消息并创建您自己的自定义通知和自定义逻辑。

参见notification-message vs data-message:

PS:如果你能通过firebase支持页面报告一个特性请求，那将会很有用。
