这是我的舱单:
<service android:name=".fcm.PshycoFirebaseMessagingServices">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service android:name=".fcm.PshycoFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
当应用程序在后台和通知到达,然后默认通知来,不运行我的onmessagerreceived代码。
这是我的onMessageReceived代码。如果我的应用程序在前台运行,而不是在后台运行,就会调用这个函数。我怎么能运行这段代码时,应用程序是在后台太?
// [START receive_message]
@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.
data = remoteMessage.getData();
String title = remoteMessage.getNotification().getTitle();
String message = remoteMessage.getNotification().getBody();
String imageUrl = (String) data.get("image");
String action = (String) data.get("action");
Log.i(TAG, "onMessageReceived: title : "+title);
Log.i(TAG, "onMessageReceived: message : "+message);
Log.i(TAG, "onMessageReceived: imageUrl : "+imageUrl);
Log.i(TAG, "onMessageReceived: action : "+action);
if (imageUrl == null) {
sendNotification(title,message,action);
} else {
new BigPictureNotification(this,title,message,imageUrl,action);
}
}
// [END receive_message]
根据firebase文档在发送下游使用firebase,有两种类型的有效载荷:
数据
此参数指定消息有效负载的自定义键-值对。
客户端应用程序负责处理数据消息。数据消息只有自定义键值对。
通知
此参数指定通知有效负载的预定义的、用户可见的键-值对。FCM自动代表客户端应用程序将消息显示给最终用户设备。通知消息具有一组预定义的用户可见键。
当你在前台时,你可以使用onmessagerecreceived()在FCM内部获取数据,你可以从数据有效载荷中获取数据。
data = remoteMessage.getData();
String customData = (String) data.get("customData");
当您在后台时,FCM将根据通知有效载荷的信息在系统托盘中显示通知。系统托盘上用于通知的标题、消息和图标都来自通知有效负载。
{
"notification": {
"title" : "title",
"body" : "body text",
"icon" : "ic_notification",
"click_action" : "OPEN_ACTIVITY_1"
}
}
当你想在应用程序处于后台时自动在系统托盘上显示通知时,使用这个通知有效载荷。
当你的应用程序在后台运行时,为了获得通知数据,你应该在通知有效载荷中添加click_action。
如果你想打开你的应用并执行一个特定的动作(在后台),在通知有效载荷中设置click_action,并将其映射到你想要启动的Activity中的意图过滤器。例如,将click_action设置为OPEN_ACTIVITY_1来触发一个意图过滤器,如下所示:
<intent-filter>
<action android:name="OPEN_ACTIVITY_1" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
把intent-filter放在你的清单上,在你的一个activity标签里面。当你点击通知时,它将打开应用程序并直接进入你在click_action中定义的活动,在本例中为“OPEN_ACTIVTY_1”。
在这个活动中,你可以通过以下方式获取数据:
Bundle b = getIntent().getExtras();
String someData = b.getString("someData");
我使用FCM为我的android应用程序和使用两个有效载荷。
下面是我使用的JSON示例:
{
"to": "FCM registration ID",
"notification": {
"title" : "title",
"body" : "body text",
"icon" : "ic_notification",
"click_action" : "OPEN_ACTIVITY_1"
},
"data": {
"someData" : "This is some data",
"someData2" : "etc"
}
}
感谢你们所有人的回答。但是我通过发送数据消息而不是发送通知来解决这个问题。
服务器代码
<?php
$url = "https://fcm.googleapis.com/fcm/send";
$token = "C-l6T_a7HouUK****";
$serverKey = "AAAAaOcKS00:********";
define( 'API_ACCESS_KEY', $serverKey );
$registrationIds = array($token);
// prep the bundle
$msg = array
(
'message' => 'here is a message. message',
'title' => 'This is a title. title',
'subtitle' => 'This is a subtitle. subtitle',
'tickerText' => 'Ticker text here...Ticker text here...Ticker text
here',
'vibrate' => 1,
'sound' => 1,
'largeIcon' => 'large_icon',
'smallIcon' => 'small_icon'
);
$fields = array
(
'registration_ids' => $registrationIds,
'data' => $msg
);
$headers = array
(
'Authorization: key=' . API_ACCESS_KEY,
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send'
);
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch );
curl_close( $ch );
echo $result;
?>
并在onmessagerreceived中捕获数据
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
sendNotification(remoteMessage.getData().get("message"));
}
// Check if message contains a notification payload.
else if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
sendNotification(remoteMessage.getNotification().getBody());
}
}
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, Notify.class).putExtra("msg",messageBody);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
String channelId = "idddd";
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(MyFirebaseMessagingService.this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("FCM Message")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}
1. 为什么会这样?
FCM (Firebase Cloud Messaging)中有两种类型的消息:
显示消息:这些消息仅在应用程序处于前台时触发onmessagerreceived()回调
数据消息:这些消息触发onmessagerreceived()回调,即使你的应用程序在前台/后台/被杀死
注意:Firebase团队还没有开发用于发送数据消息的UI
还有你的设备。您应该使用您的服务器发送这种类型!
2. 如何?
为了实现这一点,你必须对以下URL执行POST请求:
文章https://fcm.googleapis.com/fcm/send
头
关键字:Content-Type,值:application/json
Key: Authorization, Value: Key =<your-server-key>
主体使用主题
{
"to": "/topics/my_topic",
"data": {
"my_custom_key": "my_custom_value",
"my_custom_key2": true
}
}
或者如果你想把它发送到特定的设备
{
"data": {
"my_custom_key": "my_custom_value",
"my_custom_key2": true
},
"registration_ids": ["{device-token}","{device2-token}","{device3-token}"]
}
注意:请确保您没有添加JSON键通知
注意:要获得服务器密钥,您可以在firebase控制台中找到它:您的项目->设置->项目设置->云消息传递->服务器密钥
3.如何处理推送通知消息?
这是你如何处理收到的消息:
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Map<String, String> data = remoteMessage.getData();
String myCustomKey = data.get("my_custom_key");
// Manage data
}
