How to pass extra data to submit_sm options

[sukhrobkhakimov]

I want to insert an SMS to the database after submitting. How to pass extra data (custom data like client_id which is specific to my app) to submit_sm options.

@Sukhrob you're doing the inverse.
Normally, you wait for the response for submit_sm (submit_sm_resp) and associate the message_id with your database.

Thanks for your response @ti24horas. Here is the code:

var sms = JSON.parse(data); // Coming from RabbitMQ consumer

// Send an SMS
session.submit_sm({
    registered_delivery: true,
    source_addr: sms.sender,
    destination_addr: sms.recipient,
    short_message: sms.message
}, function (pdu) { // Here, I would want to bind each client to their own SMSs like this if possible: function (pdu, sms) {
    var parameters = {
        client_id: sms.client_id, // Is it safe to put client_id here directly as it is an asynchronous request?
        sender: pdu.source_addr,
        recipient: pdu.destination_addr,
        message: pdu.short_message,
        message_id: pdu.message_id,
        status: pdu.command_status,
        created_at: new Date()
    };

    // Save an SMS to the database
});

Say, if there are 10 clients which send a lot of SMSs per second, can one client overwrite another one's SMS?

If your code is inside a function scope and you call submit_sm once in this scope (i.e. not in a loop) and you don't alter sms variable in this scope later, it's most likely safe to use the code you quoted.
