npm-gcm不会向设备发送通知

Question

guys, I want to send a notification to the android device using npm-gcm and here is my code:

var sender = new gcm.Sender('myAPIkey');

var message = new gcm.Message();

message.addNotification('title', 'Backend!!!');
message.addNotification('body', 'Bitch');
var regTokens = ['deviceToken1'];
console.log(message)
regTokens.push('deviceToken2')

sender.send(message, { registrationTokens: regTokens }, function (err, response) {
    if (err) console.error(err);
        else console.log(response);
});

and in the console I get:

{ multicast_id: 7664202372197545000,
  success: 2,
  failure: 0,
  canonical_ids: 0,
  results:
  [ { message_id: '0:1481660978053751%cc7dad02f9fd7ecd' },
    { message_id: '0:1481660978045814%cc7dad02f9fd7ecd' } ]
 }

but the devices did not receive any notification. What is the problem? Why is this happening? Can you give me an advice?!

Based on this SO post ,there might be an issue with "notification" object on node-gcm code. Try to use message.addData and check if it works. Make sure that you followed this tutorial and this thread that gives sample code on how to send simple message to your device.

var sender = new gcm.Sender(googleApiKey);
var message = new gcm.Message();
message.addData('key1','testdarinodegcm');
message.delay_while_idle = 1;
var registrationIds = [];
registrationIds.push('APA91bHCzBP6wEfExCZlSXgf0wuOC6QEWJ-7MVFl3hgaW3Jv8FslsofGJ-      qgdliyS8zjwy_W7zPaKsEZx6kbeuWdoAAexawKl1Qd6GEGV_v844n1LMRaTsWeiwI9iaLGKKq_R3scY_wuRG8uG2SZ5X9q0J67Ko3gcw');
sender.send(message, registrationIds, 4, function (err, result) {
console.log(result);
});

Hope this helps!
