Firebase Java Server pour envoyer une notification Push à tous les périphériques
J'essaie d'envoyer une notification Push à mon appareil Android avec le nouveau service Firebase . J'ai enregistré et configuré une application. J'ai également mis tout le code nécessaire pour recevoir une notification dans l'application Android . Via la console Firebase. Je peux envoyer une notification à mon application et celle-ci est reçue et affichée . Maintenant, je souhaite écrire un serveur autonome Java, pour envoyer une notification à TOUS les appareils. Ceci est mon code actuel:
final String apiKey = "I added my key here";
URL url = new URL("https://fcm.googleapis.com/fcm/send");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Authorization", "key=" + apiKey);
conn.setDoOutput(true);
String input = "{\"notification\" : {\"title\" : \"Test\"}, \"to\":\"test\"}";
OutputStream os = conn.getOutputStream();
os.write(input.getBytes());
os.flush();
os.close();
int responseCode = conn.getResponseCode();
System.out.println("\nSending 'POST' request to URL : " + url);
System.out.println("Post parameters : " + input);
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
// print result
System.out.println(response.toString());
Et voici le résultat que je reviens de leurs serveurs:
{"multicast_id":6602141464107786356,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}
Malheureusement, le simple fait de supprimer la balise "to" ne fonctionne pas, un code 400 est renvoyé puis . J'ai lu que je devais enregistrer le périphérique, envoyer l'ID de périphérique au serveur, le sauvegarder à cet emplacement puis en boucle. pour envoyer le message à tous les périphériques enregistrés sur le serveur . N'existe-t-il pas un moyen plus simple d'envoyer simplement un message à tous les périphériques, comme dans la console?
Votre aide est vraiment appréciée, car j'essaie de faire en sorte que cela fonctionne toute la journée = (
Cordialement, Dustin
Je ne crois pas que ce soit possible. Au lieu de cela, je suggérerais d'enregistrer tous les périphériques sur le même sujet et vous pourrez ensuite envoyer un message à tous les périphériques en même temps. Voici la documentation d'aide à ce sujet:
Envoyer des messages de sujet à partir du serveur
https://firebase.google.com/docs/cloud-messaging/topic-messaging
Cette solution envoie une notification Push à Firebase à l'aide d'Apache HttpClient:
HttpClient client = HttpClientBuilder.create().build();
HttpPost post = new HttpPost("https://fcm.googleapis.com/fcm/send");
post.setHeader("Content-type", "application/json");
post.setHeader("Authorization", "key=AIzaSyBSxxxxsXevRq0trDbA9mhnY_2jqMoeChA");
JSONObject message = new JSONObject();
message.put("to", "dBbB2BFT-VY:APA91bHrvgfXbZa-K5eg9vVdUkIsHbMxxxxxc8dBAvoH_3ZtaahVVeMXP7Bm0iera5s37ChHmAVh29P8aAVa8HF0I0goZKPYdGT6lNl4MXN0na7xbmvF25c4ZLl0JkCDm_saXb51Vrte");
message.put("priority", "high");
JSONObject notification = new JSONObject();
notification.put("title", "Java");
notification.put("body", "Notificação do Java");
message.put("notification", notification);
post.setEntity(new StringEntity(message.toString(), "UTF-8"));
HttpResponse response = client.execute(post);
System.out.println(response);
System.out.println(message);
Utilisez le code ci-dessous pour envoyer des notifications Push à plusieurs appareils:
import Java.io.IOException;
import Java.util.ArrayList;
import Java.util.List;
import com.google.Android.gcm.server.Message;
import com.google.Android.gcm.server.MulticastResult;
import com.google.Android.gcm.server.Result;
import com.google.Android.gcm.server.Sender;
public class PushNotifactionHelper {
public final static String AUTH_KEY_FCM = "your key ";
public final static String API_URL_FCM = "https://fcm.googleapis.com/fcm/send";
public static void sendPushNotification(List<String> deviceTokenList) {
Sender sender = new Sender(AUTH_KEY_FCM);
Message msg = new Message.Builder().addData("message", "Message body")
.build();
try {
MulticastResult result = sender.send(msg, deviceTokenList, 5);
for (Result r : result.getResults()) {
if (r.getMessageId() != null)
System.out.println("Push Notification Sent Successfully");
else
System.out.println("ErrorCode " + r.getErrorCodeName());
}
} catch (IOException e) {
System.out.println("Error " + e.getLocalizedMessage());
}
}
}
Remarque: utilisez gcm.server.jar
Votre JSON sera comme ça:
{ "registration_ids": [ "fcm token 1", "fcm token 2", "fcm token 3" ], "data": { "message": "msg" }, "notification": { "title": "App name", "text": " your msg" } }
public void sendGroupPush(Context context, ArrayList tokenlist, String message) {
String msg = message;
String title = context.getString(R.string.app_name);
JSONArray regId = null;
JSONObject objData = null;
JSONObject data = null;
JSONObject notif = null;
try {
regId = new JSONArray();
for (int i = 0; i < tokenlist.size(); i++) {
regId.put(tokenlist.get(i));
}
data = new JSONObject();
data.put("message", message);
notif = new JSONObject();
notif.put("title", title);
notif.put("text", msg);
objData = new JSONObject();
objData.put("registration_ids", regId);
objData.put("data", data);
objData.put("notification", notif);
Log.e("!_@rj@_group_PASS:>", objData.toString());
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.POST, Constants.FCM_Push_GROUP_URL, objData,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.e("!_@rj@_@@_SUCESS", response + "");
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e("!_@rj@_@@_Errors--", error + "");
}
}) {
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Authorization", "key=" + Constants.FCM_API_KEY);
params.put("Content-Type", "application/json");
Log.e("!_@rj@_@@Push_headrers", "::> " + params);
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(context);
int socketTimeout = 1000 * 60;// 60 seconds
RetryPolicy policy = new DefaultRetryPolicy(socketTimeout, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
jsObjRequest.setRetryPolicy(policy);
requestQueue.add(jsObjRequest);
}
public static String FCM_Push_URL = " https://fcm.googleapis.com/fcm/send ";
Ici, j'ai aussi une solution très simple pour envoyer un groupe de messages Push individuel
public class FCM {
final static private String FCM_URL = "https://fcm.googleapis.com/fcm/send";

Calling should be like that :
public class TestFCM {

public static void main(String[] args) {
//Just I am passed dummy information
// DeviceID's
String tokenId1 = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
String tokenId = "yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy";
String server_key ="<Server Key>" ;
String message = "Welcome alankit Push Service.";
putIds= new ArrayList<>();
putIds.add(tokenId1);
putIds.add(tokenId);
/* for Group*/
FCM.send_FCM_NotificationMulti(putIds,tokenId,server_key,message);
/*for indevidual*/
FCM.send_FCM_Notification( tokenId,server_key,message);
}
}
votre code est parfait il suffit de revérifier l'ID d'enregistrement de l'utilisateur à qui vous envoyez la notification. À la place de to, utilisez le périphérique de l'utilisateur regid . Cela a parfaitement fonctionné pour moi.
@Autowired
AndroidPushNotificationsService androidPushNotificationsService;
@RequestMapping(value = "/send", method = RequestMethod.GET, produces = "application/json")
public ResponseEntity<String> send() {
JSONObject body = new JSONObject();
// JsonArray registration_ids = new JsonArray();
// body.put("registration_ids", registration_ids);
body.put("to", "xxxxxxxxxxxxxxxxxxxjPwZpLgLpji_");
body.put("priority", "high");
// body.put("dry_run", true);
JSONObject notification = new JSONObject();
notification.put("body", "body string here");
notification.put("title", "title string here");
// notification.put("icon", "myicon");
JSONObject data = new JSONObject();
data.put("key1", "value1");
data.put("key2", "value2");
body.put("notification", notification);
body.put("data", data);
HttpEntity<String> request = new HttpEntity<>(body.toString());
CompletableFuture<FirebaseResponse> pushNotification = androidPushNotificationsService.send(request);
CompletableFuture.allOf(pushNotification).join();
try {
FirebaseResponse firebaseResponse = pushNotification.get();
if (firebaseResponse.getSuccess() == 1) {
log.info("Push notification sent ok!");
} else {
log.error("error sending Push notifications: " + firebaseResponse.toString());
}
return new ResponseEntity<>(firebaseResponse.toString(), HttpStatus.OK);
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
return new ResponseEntity<>("the Push notification cannot be send.", HttpStatus.BAD_REQUEST);
}

Le code côté client Android devrait être:
//subscribe_topic with name "ALL"
FirebaseMessaging.getInstance().subscribeToTopic("ALL");
Du côté serveur:
string json = "{\"to\": \"/topics/ALL\",\"data\": {\"message\": \"This is a Cloud Messaging Topic Message\",}}";
Utilisez le code ci-dessous pour envoyer le Push à plusieurs périphériques à l'aide de FCM.
public void sendAndroidPush(String input) {

conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Authorization", "key=" + apiKey);
conn.setDoOutput(true);
OutputStream os = conn.getOutputStream();
os.write(input.getBytes());
os.flush();
os.close();
int responseCode = conn.getResponseCode();
System.out.println("\nSending 'POST' request to URL : " + url);
System.out.println("Post parameters : " + input);
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
} catch(Exception e) {
e.printStackTrace();
}
// print result
System.out.println(response.toString());
}
JSONArray devices = new JSONArray();
devices.put("Your Actual Device Token");
JSONObject payloadObj = new JSONObject();
try {

notifyObj.put("title","Your Title");
notifyObj.put("text", "Your Text");
payloadObj.put("registration_ids",devices.toString());
payloadObj.put("notification",notifyObj.toString());
} catch (Exception e) {
// TODO: handle exception

}
sendAndroidPush(payloadObj.toString());
