我正在尝试使用Messenger应用程序，但这里的转折是我有2个实体（即2个应用程序A＆amp; B ）。
现在我正在尝试使用Firebase在两者之间放置消息传递逻辑。 Firebase不支持在同一 项目网址 上的两个不同应用程序（ A＆amp; B ）之间的通信。为了克服这个限制，我也为应用B使用了相同的google-service.json app A.
对于应用B，我刚刚更改了项目id和auth key。这似乎按照我的意图行事。我已经使用Firebase控制台测试了推送通知，但它似乎一直在运行。
然后我尝试实现服务器逻辑。进行一对一通知。
案例1
但问题出现在应用程序B中，如果我发送通知请求，我会收到MismatchSenderId错误，其中项目ID未经过调整。
{"multicast_id":[removed],"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"MismatchSenderId"}]}
案例2
对于应用A，以下是我得到的以下回复：
{"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，但是当我从设备发出请求时它不会发送。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，它可以完美地工作。
以下是我的代码 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* The Application's current Instance ID token is no longer valid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());
}
}
以下是Application标记
<service
android:name=".MyFirebaseMessagingService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>

android:name=".MyFirebaseInstanceIDService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
TIA
CASE 1已解决
我设法解决了CASE 1，对于B我必须使用B的服务器api密钥，类似于A
编辑2
添加了服务器端代码
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;
}
答案 0 :(得分：0)
1）确保您向fcm发送有效的json。 2）确保您发送的是正确的令牌。
有关如何发送通知的其他信息：
向特定设备发送消息
要将消息发送到特定设备，请将其设置为特定应用实例的注册令牌
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
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密钥
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
问题在于服务器配置。如果您想在单个服务器中管理两个firebase应用程序，则必须使用位于以下位置的Firebase APK_KEY配置两个firebase应用程序：
转到Firebase控制台中的应用程序 - ＆gt;点击右上角的三个点 - ＆gt;管理 - ＆gt;云消息 - ＆gt; （服务器密钥）
获得两个应用程序的两个服务器密钥后，必须按如下方式配置：
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
答案 1 :(得分：-4)
我修正了错误MismatchSenderId
示例，如下：
有效令牌：cwsm26j-8qM：APA91bEGbg5xxxxxxxxxxxxxxxxxxxxxx
无效令牌：APA91bEGbg5xxxxxxxxxxxxxxxxxxxxxx
