With reference to the methods below. How exactly does authourization of ESME to the SMPP server occur.
I would wish to call an API on my ruby app to cross check info and balance as part of authourization and go on to send submit message
// Ask the callback (if there is one) if the credentials are okay
if (self.listeners('bind').length > 0) {
self.emit('bind', self, pdu, function(status) {
self.bindAuthorization(pdu, status);
});
} else {
self.bindAuthorization(pdu, "ESME_ROK");
}
};
self.bindAuthorization = function(pdu, status) {
var newPdu, command;
switch (self.bind_type) {
case smpp.RECEIVER:
command = "bind_receiver_resp";
break;
case smpp.TRANSMITTER:
command = "bind_transmitter_resp";
break;
case smpp.TRANSCEIVER:
command = "bind_transceiver_resp";
break;
}
newPdu = {
command: command,
command_status: status,
sequence_number: pdu.sequence_number,
fields: {
system_id: self.config.system_id
},
optional_params: {}
};
// Create a new PDU with our response
if (status === "ESME_ROK") {
self.system_id = pdu.system_id.toString('ascii');
self.bound = true;
self.socket.setTimeout(self.config.timeout * 1000);
self.socket.on('timeout', self.enquire_link);
} else {
self.bound = false;
self.bind_type = smpp.UNBOUND;
}
self.sendPdu(newPdu);
self.emit('bindSuccess', self, pdu);
};
