问题描述

我正在尝试实现Firebase通知.但是我很难找到有关如何从Firebase通知中检索自定义数据的任何文档.

I'm trying to implement firebase notifications. But I have trouble finding any documentation on how to retrieve custom data from firebase notification.

但是在代码中如何获取自定义密钥.

But in in code how to get the custom key.

我正在使用FirebaseMessagingService.onMessageReceived来获取消息数据.

I'm using FirebaseMessagingService.onMessageReceived to get the message data.

@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, "Notification Message Body: " + remoteMessage.getNotification().getBody());
}

推荐答案

您可以使用以下方法检查自定义数据:

You can check your custom data using:

for (Map.Entry<String, String> entry : remoteMessage.getData().entrySet()) {
    String key = entry.getKey();
    String value = entry.getValue();
    Log.d(TAG, "key, " + key + " value " + value);
}

要获取特定密钥:

String value = remoteMessage.getData().get("<YOUR_KEY>");
