问题描述
我正在尝试开发一个信使应用程序，但这里的转折是我在这里有 2 个实体(即 2 个应用程序 A 和 B).
I'm trying to work on a messenger app, but the twist here is I have 2 Entities (i.e. 2 apps A & B) here.
现在我正在尝试使用 Firebase 在两者之间放置消息传递逻辑.Firebase 不支持两个不同的应用程序(A 和 B)通过相同的项目 url 进行通信.为了克服这个限制，我也为应用 B 使用了与应用 A 相同的 google-service.json.
Now I'm trying to put messaging logic between the two using Firebase. Firebase doesn't support communication between two different applications (A & B) over the same project url. In order to overcome that restriction, I have used the same google-service.json of app A for app B as well.
对于应用 B，我刚刚更改了项目 id 和 auth key.这似乎按我的预期工作.我也使用 Firebase 控制台测试了推送通知，它似乎一直在工作.
For app B, I have just changed the project id and auth key. That seems to have worked as I intended. I have tested the push notification as well using the Firebase Console and it seemed to have been working.
然后我尝试实现服务器逻辑.发出一对一通知.
Then I have tried to implement the server logic. To make one-on-one notification.
案例 1
但是这里出现的问题是，从应用程序 B 中，如果我发送通知请求，我会收到一个 MismatchSenderId 错误，其中项目 id 没有经过调整.
But the problem arises here is that from app B, if I send a notification request, I get a MismatchSenderId error where the project id has not been tempered with.
{"multicast_id":[removed],"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"MismatchSenderId"}]}
案例 2
对于应用 A，我得到以下响应:
and for app A, here is the following response I get:
{"multicast_id":[removed],"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1473661851590851%0e4bcac9f9fd7ecd"}]}
为此，成功值为 1 因此，应该发送通知，但当我从设备发出请求时它没有发送.但是当我使用 Postman 或任何其他客户端执行相同的服务器调用时，它可以完美运行.
For this, the success value is 1 hence, the notification should be sent but it's not sending when I'm making the request from the device. But it works flawlessly when I perform the same server call using Postman or any other client.
这是我的代码MyFirebaseInstanceIDService.java
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";
private static final String FRIENDLY_ENGAGE_TOPIC = "friendly_engage";
@Override
public void onCreate() {
String savedToken = Utility.getFirebaseInstanceId(getApplicationContext());
String defaultToken = getApplication().getString(R.string.pref_firebase_instance_id_default_key);
Log.d("GCM", savedToken);
if (savedToken.equalsIgnoreCase(defaultToken))
//currentToken is null when app is first installed and token is not available
//also skip if token is already saved in preferences...
{
String CurrentToken = FirebaseInstanceId.getInstance().getToken();
if (CurrentToken != null)
Utility.setFirebaseInstanceId(getApplicationContext(), CurrentToken);
Log.d("Value not set", CurrentToken);
updateFCMTokenId(CurrentToken);
}
super.onCreate();
}
/**
* The Application's current Instance ID token is no longer valid
* and thus a new one must be requested.
*/
@Override
public void onTokenRefresh() {
// If you need to handle the generation of a token, initially or
// after a refresh this is where you should do that.
String token = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "FCM Token: " + token);
Utility.setFirebaseInstanceId(getApplicationContext(), token);
updateFCMTokenId(token);
}
private void updateFCMTokenId(final String token) {
SQLiteHandler db = new SQLiteHandler(getBaseContext());
final HashMap<String, String> map = db.getUserDetails();
//update fcm token for push notifications
StringRequest str = new StringRequest(Request.Method.POST, AppConfig.UPDATE_GCM_ID, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Log.d("GCM RESPONSE", response);
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
}) {
@Override
protected Map<String, String> getParams() throws AuthFailureError {
HashMap<String, String> param = new HashMap<>();
param.put("user_id", map.get("uid"));
param.put("gcm_registration_id", token);
return param;
}
};
str.setShouldCache(false);
str.setRetryPolicy(new DefaultRetryPolicy(AppConfig.DEFAULT_RETRY_TIME, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
AppController.getInstance().addToRequestQueue(str);
}
}
FirebaseMessagingService.java
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
//Displaying data in log
//It is optional
try {
Log.d(TAG, "From: " + remoteMessage.getFrom());
Log.d(TAG, "Notification Message Body: " + remoteMessage.getData().get("message"));
} catch (Exception e) {
e.printStackTrace();
}
//Calling method to generate notification
sendNotification(remoteMessage.getData().get("message"));
}
//This method is only generating push notification
//It is same as we did in earlier posts
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, ChatRoomActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
android.support.v4.app.NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("NAME")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}
这是 Application 标签内的 Manifest.xml 中的声明
And here is the declaration in the Manifest.xml within Application tag
<service
android:name=".MyFirebaseMessagingService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service
android:name=".MyFirebaseInstanceIDService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
TIA
案例 1 已解决
我已经设法解决了案例 1，对于 B 我必须使用 B 的服务器 api 密钥，对于 A 类似
I have managed to solve CASE 1 where for B I had to use the server api key of B , similarly for A
编辑 2
添加服务器端代码
public function sendNotification($message, $gcm_id, $user_level)
{
if ($user_level == "level") {
$server_key = "xys";
} else $server_key = "ABC";
$msg = array
(
'message' => $message,
'title' => 'Title',
'vibrate' => 1,
'sound' => 1,
'largeIcon' => 'large_icon',
'smallIcon' => 'small_icon'
);
$fields = array
(
'to' => $gcm_id,
'data' => $msg
);
$headers = array
(
'Authorization: key=' . $server_key,
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/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;
}
推荐答案
编辑#1:
1) 确保向 fcm 发送有效的 json.2) 确保您发送到正确的令牌.
Edit #1:
1) Make sure you are sending a valid json to the fcm. 2) Make sure you are sending to the right token.
关于如何发送通知的其他信息:
Other informations on how to send notifications:
向特定设备发送消息
要将消息发送到特定设备，请将 设置为特定应用实例的注册令牌
To send messages to specific devices, set the to the registration token for the specific app instance
curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>" -X POST -d '{ "data": { "score": "5x1","time": "15:10"},"to" : "<registration token>"}' https://fcm.googleapis.com/fcm/send
向主题发送消息
这里的主题是:/topics/foo-bar
here the topic is : /topics/foo-bar
curl -H "Content-type: application/json" -H "Authorisation:key=<Your Api key>" -X POST -d '{ "to": "/topics/foo-bar","data": { "message": "This is a Firebase Cloud Messaging Topic Message!"}}' https://fcm.googleapis.com/fcm/send
向设备组发送消息
向设备组发送消息与向单个设备发送消息非常相似.将 to 参数设置为设备组的唯一通知键
Sending messages to a device group is very similar to sending messages to an individual device. Set the to parameter to the unique notification key for the device group
curl -H "Content-type: application/json" -H "Authorisation:key=<Your Api key>" -X POST -d '{"to": "<aUniqueKey>","data": {"hello": "This is a Firebase Cloud Messaging Device Group Message!"}}' https://fcm.googleapis.com/fcm/send
原文:
问题是你的服务器配置.如果您想在单个服务器中管理两个 Firebase 应用程序，您必须使用位于以下位置的 Firebase APK_KEY 配置两个 Firebase 应用程序:
Original:
The problem is you server configuration. If you want to manage two firebase apps in single server you have you have to config two firebase apps with your Firebase APK_KEY that located at:
在 Firebase 控制台中转到您的应用程序 -> 点击右上角的三个点 -> 管理 -> CLOUD MESSAGES ->(服务器密钥)
Go to your applications in Firebase console -> Click on three dots at the top right -> Manage -> CLOUD MESSAGES -> (Server key)
获得两个应用程序的两个服务器密钥后，您必须像这样配置它:
After you get your both server keys for your two apps, you have to configure it like this:
var firebaseLib = require("firebase");
var app1Config = {
apiKey: "<PROJECT_1_API_KEY>",
authDomain: "<PROJECT_1_ID>.firebaseapp.com",
databaseURL: "https://<PROJECT_1_DATABASE_NAME>.firebaseio.com",
storageBucket: "<PROJECT_1_BUCKET>.appspot.com",
}
var app2Config = {
apiKey: "<PROJECT_2_API_KEY>",
authDomain: "<PROJECT_2_ID>.firebaseapp.com",
databaseURL: "https://<PROJECT_2_DATABASE_NAME>.firebaseio.com",
storageBucket: "<PROJECT_2_BUCKET>.appspot.com",
}
var firebaseApp1 = firebaseLib.initailize(app1Config); // Primary
var firebaseApp2 = firebaseLib.initailize(app2Config, "Secondary"); // Secondary
