Send push notification from cloud code

[oyvindvol]

With the Push addition to Parse Server, is it possible to send push notifications from cloud code like before?

Parse.Push.send({});

[gfosco]

Yes, but you must set the useMasterKey option to true.

Parse.Push.send({ ... }, { useMasterKey: true }).then(...)

[oyvindvol]

Thanks, would this be the correct way to put it? :

var query = new Parse.Query(Parse.Installation);
query.equalTo('channels', 'test-channel');

Parse.Push.send(
  {
    where: query,
    data: 
    {
      alert: 'Test',
      badge: 1,
      sound: 'default'
    }
  }, 
  {
    success: function() {
      console.log('##### PUSH OK');
    },
    error: function(error) {
      console.log('##### PUSH ERROR');
    }
  },
  { useMasterKey: true });

[gfosco]

It would be like this:

var query = new Parse.Query(Parse.Installation);
query.equalTo('channels', 'test-channel');

Parse.Push.send({
  where: query,
  data: {
    alert: 'Test',
    badge: 1,
    sound: 'default'
  }
}, {
  success: function() {
    console.log('##### PUSH OK');
  },
  error: function(error) {
    console.log('##### PUSH ERROR');
  },
  useMasterKey: true
});

Or, since you're just sending to a channel:

Parse.Push.send({
  channels: ['test-channel'],
  data: {
    alert: 'Test',
    badge: 1,
    sound: 'default'
  }
}, {
  success: function() {
    console.log('##### PUSH OK');
  },
  error: function(error) {
    console.log('##### PUSH ERROR');
  },
  useMasterKey: true
});

I like promises syntax instead:

Parse.Push.send({
  channels: ['test-channel'],
  data: {
    alert: 'Test',
    badge: 1,
    sound: 'default'
  }
}, { useMasterKey: true }).then(() => {
  console.log('Push ok');
}, (e) => {
  console.log('Push error', e);
});

Spend hours trying to figure this out. Was missing useMasterKey: true after the error:

Thank you!

[oyvindvol]

Thanks, but I still have issues. After updating my code to use the masterKey, i get the error "Cannot use the Master Key, it has not been provided." in the heroku logs.

Then I set this in the top of my main.js:
Parse.masterKey = '<masterKey>';

Then I got the error "You need to call Parse.initialize before using Parse." in the heroku logs.

After setting this in the top of my main.js:

Parse.initialize('<appId>', 'clientKey');
Parse.serverURL = 'https://<appname>.herokuapp.com/parse';

The heroku log says: "##### PUSH ERROR: Push adapter is not availabe".

[gfosco]

During initialization of the ParseServer instance, we set the global Parse object and initialize it with the master key.

Are you overwriting the Parse global anywhere by requiring it again?

[oyvindvol]

No, I can`t see anywhere I do that. I use the parse-server-example out of the box, deployed with the Heroku-button on the GitHub page.

[gateway]

@gfosco @oyvindvol I'm not sure the parse-server-example has been updated to install the latest parse-server 2.0.8.x and the new update to node.js 4.3 due to a security issue in 4.1 .. someone should update that so people are pulling the latest 2.0.8 to avoid potential bugs being reported from a older version.. ??

Is there a way to useMasterKey in Android when sending push notifications using ParsePush like :
ParsePush push = new ParsePush();
push.setQuery(query);
push.setData(jsonData);
push.sendInBackground();

[chriscborg]

I've tried the above syntax but I'm getting an unauthorized error logged. I've tried changing the query to channels:["user"] just to make sure that the issue was not from querying users, but still no luck. Any ideas?

        // Find devices associated with the recipient user
        var recipientUser = new Parse.User();
        recipientUser.id = recipientUserId; //the object id of the user that should receive the notification

        var pushQuery = new Parse.Query(Parse.Installation);
        pushQuery.equalTo("owner", recipientUser);

        var pushQuery2 = new Parse.Query(Parse.Installation);
        pushQuery2.equalTo("user", recipientUser);

        var mainQuery = Parse.Query.or(pushQuery, pushQuery2);
        console.log(recipientUser);
        // Send the push notification to results of the query
        Parse.Push.send({
            where: mainQuery,
            data: {
                alert: message,
                sound: "Default",
                badge: "Increment",
                "chatroom": chatroom
            }
        }, {
            success: function() {
                console.log('##### PUSH OK');
                response.success(points);
            },
            error: function(error) {
                console.log('##### PUSH ERROR: ' + error.message);
                response.error("Push failed to send with error: " + error.message);
            },
            useMasterKey: true
        });

Here is a blog post on how to setup push notifications server-side and and Android app. It took me so long to figure it how, hope it helps. http://www.tuogol.com/parse-server-android-push-notifications/

[mankan1]

I tried the blog post from Matthew, but the ParseCloud.callFunctionInBackground errors out with Invalid function
ParseCloud.callFunctionInBackground("sendAnnouncement", params, new FunctionCallback() {
public void done(String result, ParseException e) {
if (e == null) {
Utils.d("ANNOUNCEMENT SUCCESS");
} else {
Utils.e("ANNOUNCEMENT FAILURE");
}
}
});

[matthewrice345]

@mankan1 Is your server running? and does your main.js have the sendAnnouncement function?

[mankan1]

Server is running but does not implement sendAnnouncement function. That explains it. so do i need to implement sendAnnouncement that sends notification to all the devices. How about if I want to send it a only a few device based on a query. How do I implement sendAnnouncement to send a notification to these devices. I know that server needs to send a message to the Google cloud and GCM will take care of sending the notification by using the sender_id. Is this all that needs to be implemented ? or is there something already there in the parse server example. Thanks a lot.

[matthewrice345]

@mankan1 So it'll send it to a channel, which is defined as a group of people (or person) who have subscribed to said particular. I'll modify the article to reflect that information. So you'll want/need to subscribe the user to the channel your going to test with.
