I am working on a chat app using XMPP Protocol.
I tried following
this tutorial from github . Everything is working fine using
XMPP.
But I'm unable to receive offline messages when user comes
online.
As user A is logged out and user B sends messages to user A, and when user A logs into app, it must receive all the messages that
were sent by user B during offline session.
How can I receive these offline messages?
My app is totally stuck on this issue. Please help if anyone
knows the solution. Any help will be appreciated. Thanks
You need to enable mod_offline on server, if you are using ejabberd XMPP Server.
Here is the code needs to enable module:
ignore_pep_from_offline: true
max_user_offline_messages:
admin: 5000
all: 100
mod_offline:
access_max_user_messages: max_user_offline_messages
Write this code in ejabberd.yml config file.
It will store unto 100 messages per user received when client was offline.
At client side, you may have to register for service:
'http://jabber.org/protocol/disco#info'
If you done this, whenever offline client gets online, server will send those stored messages to respective client.
You've to send Request for offline message if server supports. XMPP works on TCP protocol so as soon as client is up, it should send request to server.

<query xmlns='http://jabber.org/protocol/disco#info'
node='http://jabber.org/protocol/offline'/>

I'm trying to get push notifications on an app that's using Twilio IP Messaging. After following the instructions on twilio guides.
The AppDelegate functions to register for remote notifications is working well - the iOS devices successfully provides the device token to the Twilio Client. However, the TwilioIPMessagingClient gives no indication of success or failure while registering the token.I have used delegates also for that Moreover, I don't get any sign of push notifications when messages get sent.
I have checked logs also where I can see the correct logs:
TNNotificationClient | Starting registration..., id: <....>
TNRegTransport | Creating registration: apn - <....>
TNRegTransport | Registration is created, location: https://ers.us1.twilio.com/v1/registrations/<...>
Where exactly I'm missing? One hint I got to know after much research that in server PHP app, I need to enable push on IPMesaging services client becuase its disabled by default. If yes, where exactly or in which .php file I have to enable it?
Reference:
https://www.twilio.com/docs/api/ip-messaging/guides/push-notification-configuration
Someone else recently solved this problem realizing that they had not set the New Message notification type to be explicitly enabled as follows from the PHP example:
// Update the service webhooks
$service = $client->services->get("YOUR_IP_MESSAGING_SERVICE_SID");
$response = $service->update(array(
"Notifications.NewMessage.Enabled" => "true",
"Notifications.NewMessage.Template" => "A New message in ${CHANNEL} from ${USER}: ${MESSAGE}",
));
?>
Would this solve it for you?
I'm currently working on a push notification API that will work with several apps at once, handling notifications and reducing programming time for future apps. It's already partially working, as I'm able to register and receive notifications on Android devices.
Eventually, one of our apps is gonna send broadcast notifications to registered users. But some tokens might be expired, which will lead to a GCM failure. I already tested, and it seems that sending an array of tokens to GCM with a single http call is working really well, as devices with valid tokens got their notifications.
What I wasn't able to find searching GCM documentation was a way to get more details in case of failure. For example, when I send a notification to two users, one with a valid token and the other with an invalid one, I got this result :
{
"multicast_id":7625209716676388798,
"success":1,
"failure":1,
"canonical_ids":0,
"results":[
{"error":"InvalidRegistration"},
{"message_id":"0:1466511379030431%c4718df8f9fd7ecd"}
]
}
We can see that one of the messages failed to send, but what I'm looking for is a way to get more details, ideally the token that leads to a failure, so I can remove it from my database.
Any way to achieve that ? Using the message_id maybe ? Or is there any solution for me to find invalid tokens stored in my database so I can clear them ? I might have missed something in the documentation, even a link to it would be useful.
Based from this documentation, the GCM server will respond to your server with some information about the token you used to try to send the push notification.
According also to this link, if the app server fails to complete its part of the registration handshake, the client app should retry sending registration token to the server or delete the registration token. Wiping old tokens from the GCM servers can be done with ÌnstanceID.deleteToken().

I am trying to implement XEP-0013 using Openfire and the gloox lib. In my XMPP client, I am calling the checkSupport() API through angloox::FlexibleOffline object in an OnConnect() event.
handleFlexibleOfflineSupport says it is supported, but I still receive offline message after presence is sent as online after login. fetchMessages() doesn't provide the messages as well. The message count that is returned is 0.
Should I configure anything on Openfire or should I change API calls?
I'm using a SaaS for my AWS instance monitoring and Mandrill for email sending/campaigns.
I had created a simple chart with Zapier but I'd rather like to host it myself. So my question is:
How can I receive a webhook signal from Mandrill and then send it to Datadog from my server? Then again I guess hosting this script right on the same server I'm monitoring would be a terrible idea...
Basically I don't know how to "receive the webhook" so I can report it back to my Datadog service agent so it gets updated on their website.
I get how to actually report the data to Datadog as explained here http://docs.datadoghq.com/api/ but I just don't have a clue how to host a listener for web hooks?
Programming language isn't important, I don't have a preference for that case.
Here you can find how to add a new webhook to your mandrill account: https://mandrillapp.com/api/docs/webhooks.php.html#method=add
tha main thing here is this:
$url = 'http://example/webhook-url';
this is your webhook URL what will process the data sent by mandrill and forward the information to Datadog.
and this is a description about what mandrill will send to your webhook URL: http://help.mandrill.com/entries/21738186-Introduction-to-Webhooks
a listener for webhooks is nothing else then a website/app which triggers an action if a request comes in. Usually you keep it secret or secure it with (http basic) authentication. E.g. create a website called http://yourdomain.com/hooklistener.php. You can then call it with HTTP POST or GET and pass some data like hooklistener.php?event=triggerDataDog or with POST and send data along with the body. You then run a script or anything you want to process that event.
A "listener" is just any URL that you host where you can receive data that is posted to it. Keep in mind, since you mentioned Zapier, you can set up a trigger that receives the webhook data - in this case the listener URL is provided by Zapier, and you can then send that data into any application (or even post to another webhook). Using Zapier is nice because it doesn't require you to write the listener code that receives the hook data and does something with it.
I created my Project Number, API key, registration ID and implemented a http server sucessfullly, but when implement css(xmpp) server, it doesn't work. I use the tutorial for java in http://developer.android.com/google/gcm/ccs.html
the console displays red alert:

Does anyone know what is going wrong here? Thanks
I was getting the same Error when I tried to implement XMPP(CCS).So after going through so many site I found that to use up streaming feature of GCM (XMPP) you need to register for this service as a trail partner.
they are saying something like this
After you have created your GCM enabled project in the API Console you must fill out this form and become a trial partner to use upstream messaging and user notifications via CCS. Access is limited to those that fill out the form. You will receive an email from Google informing you that you now have access; Google will also send you the address of an echo server that you can use to bounce messages back to your application.
so visit this site and fill form
Upstream Google Cloud Messaging and User Notifications Sign-up
Update
Now up-streaming using GCM(CCS) is open for all developers !!!
