Hello guys,
However, by using user channel we can not send broadcast message to all user
in a domain.
For example, I want to create chat like application where a user can see all
the other users status, receiving user status change from server, receiving
message directly from other user, and in the same application, I would like
to enable message push if there is any notification directly from the server
to a particular user.
The scenario will be:
1. User login using authentication system and will receive session ID.
2. The session ID will be assigned to user property as parameter when user
is connecting to APE server
// Client script
client.core.start({'name':'Username', 'sessionID':sessionID});
3. Force the user to connect to broadcast channel
// Client script
client.addEvent('ready', function() { client.core.join('broadcast'); })
4. Create on connect hook on the server side to assign the sessionID (and
name) as user property
// Server script
Ape.registerHookCmd("connect", function(params, cmd) {
cmd.user.key = params.key;
cmd.user.sessionID = params.sessionID;
}
5. When we want to send inline push to a user, it should send to the
particular user using the session ID, and APE server module need to find the
user with corresponding sessionID inside the broadcast channel
// Server script
var chan = Ape.getChannelByName(params.channel); // params.channel
should be set = 'broadcast'
var userArray = chan.userslist.some(function(user) {
if (user.getProperty('sessionID') == sessionID) {
user.pipe.sendRaw(params.raw, params.data);
return true; // to satisfy the search
}
});
I am not sure if this scenario will work or not since I haven't tested it
yet. anyone have opinion?
Cheers,
Eko
