ios に通知をプッシュするために javapns を使用し、Android デバイスに通知をプッシュするために android.gcm.server を使用しました。しかし、1 つの通知を多くのデバイスに送信すると、各デバイスに通知の複数のコピーが送信されます。この数は 2 の場合も 3 の場合もあります。何か案は ？
私のコードは以下の通りです
public void pushNotificationsToAndroid(String pushMessage,
String contentType, String content, String notification_id,
List<String> devices) {
try {
Sender sender = new Sender(
properties
.getProperty("notification.android.senderIdDemo"));
com.google.android.gcm.server.Message message = new com.google.android.gcm.server.Message.Builder()
.collapseKey("1").timeToLive(3).delayWhileIdle(true)
.addData("message", pushMessage)
.addData("content_type", contentType)
.addData("content", content)
.addData("notification_id", notification_id).build();
MulticastResult result = sender.send(message, devices, 1);
if (result.getResults() == null) {
System.out.println(result.getFailure());
logger.debug("getFailure() of sender.send() method :",
result.getFailure());
}
} catch (Exception exception) {
logger.error("erorr push notification ");
}
System.out.println("sent not at " + new Date());
logger.debug(
"exit pushNotificationsToAndroid() method : current time is ",
new Date());
}
public void pushNotificationsToIOS(String pushMessage, String contentType,
String content, String notification_id, List<String> devices)
{
boolean production = true;
String password = properties
.getProperty("notification.ios.password");
String keyStroke = properties
.getProperty("notification.ios.certFileName");
AppleNotificationServer jksServer = null;
try {
jksServer = new AppleNotificationServerBasicImpl(keyStroke,
password, ConnectionToAppleServer.KEYSTORE_TYPE_JKS,
production);
} catch (KeystoreException keystoreException) {
logger.error("erorr creating jksServer");
}
PushNotificationPayload payload = PushNotificationPayload.complex();
try {
payload.addAlert(pushMessage);
} catch (JSONException e2) {
logger.error("erorr creating payload alert");
}
try {
payload.addCustomDictionary("content_type", contentType);
} catch (JSONException e1) {
logger.error("erorr creating payload content_type");
}
try {
payload.addCustomDictionary("content", content);
} catch (JSONException e1) {
logger.error("erorr creating payload content");
}
try {
payload.addCustomDictionary("notification_id", notification_id);
} catch (JSONException e1) {
logger.error("erorr creating payload notification_id");
}
PushNotificationManager pushManager = new PushNotificationManager();
try {
pushManager.initializeConnection(jksServer);
} catch (CommunicationException | KeystoreException e) {
logger.error("erorr connecting Server");
}
try {
List<PushedNotification> notifications = pushManager
.sendNotifications(payload, Devices.asDevices(devices));
} catch (CommunicationException | KeystoreException e) {
logger.error("erorr push notifications");
}
}
