我正在尝试使用Firebase云消息传递。我将来自Node.js服务器的通知发送到我注册到通知系统的应用程序。
我的问题是,在Android 5.1上,即使我在nofitification json中设置了title属性,通知也是“FCM消息”。它在Android 6.0中运行良好。我也尝试重新启动设备。
这是我用来发送通知的代码:
function sendNotificationToUser(userToken, message, onSuccess) {
request({
url: 'https://fcm.googleapis.com/fcm/send',
method: 'POST',
headers: {
'Content-Type' :' application/json',
'Authorization': 'key='+API_KEY
},
body: JSON.stringify({
notification: {
"title": 'My App Name',
"body": message,
"sound": 'default'
},
to : userToken
})
}, function(error, response, body) {
if (error) { console.error(error); }
else if (response.statusCode >= 400) {
console.error('HTTP Error: '+response.statusCode+' - '+response.statusMessage);
}
else {
onSuccess();
}
});
}
正如您所看到的,我发送的通知标题是“我的应用名称”,但在设备上显示“FCM消息”。
我该怎么做?!

您需要传递标题,然后在JSONObject jsonObject = new JSONObject(remoteMessage.getData());
中接收它,这将捕获标题,然后显示在顶部或从网络传递完整的JSON并像这样接收
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// ...
// TODO(developer): Handle FCM messages here.
// Not getting messages here? See why this may be: https://firebase.google.com/support/faq/#fcm-android-background
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());
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
}
// 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.
}
这是完整的方法:
Maven + Selenium + Jenkins

这是预期的。 (经过Android 10测试)
FCM对于应用程序状态(前台和后台/已终止)具有不同的行为。 您应该根据用例,通过从服务器发送的有效负载来处理此问题。
从服务器发送的味精必须以“通知”或“数据”格式从仪表板或服务器端api发送。 注意:您只能从Firebase dashobard发送“通知”正文,而不能发送数据。在这种情况下,FCM将直接显示通知,而不会回调您的应用。
服务器端 以下是示例格式:
通知类型格式 注意:默认情况下,Android系统将在通知托盘中显示通知,而您无需显示它。
{
"to": "your_token_id",
"notification" : {
"title" : "FCM Notification title!",
"body" : "FCM Notification subtext!",
"content_available" : true,
"priority" : "high"
}
}
数据格式(用于在前台和后台接收应用中的回调) 注意:您必须自行处理回调并显示notif。
{
"to": "your_token_id",
"data" : {
"title" : "FCM Notification Title ",
"subtext" : "FCM Notification Sub Title",
"type" : "999",
"priority" : "high"
}
}
Android客户端 要处理您的Android接收器中收到的有效载荷,请查阅官方指南here
override fun onMessageReceived(remoteMessage: RemoteMessage) {
Log.d(TAG, "From: ${remoteMessage.from}")
// Check if message contains a data payload.
remoteMessage.data.isNotEmpty().let {
Log.d(TAG, "Message data payload: " + remoteMessage.data)
if (/* Check if data needs to be processed by long running job */ true) {
// For long-running tasks (10 seconds or more) use WorkManager.
scheduleJob()
} else {
// Handle message within 10 seconds
handleNow()
}
}
// Check if message contains a notification payload.
remoteMessage.notification?.let {
Log.d(TAG, "Message Notification Body: ${it.body}")
}
// 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.
