如何使用节点smpp发送长消息? [英] how to send long message using node smpp?

问题描述

exports.sendSMS = function (session, to, text, sourceAddress, jsonMessageHistoryIds, callback) {

     console.log('messege',text);

    session.submit_multi({
        source_addr: sourceAddress,
        dest_address: to,
        short_message: text

    }, function (pdu) {
        console.log('submit_multi: ', pdu.command_status);
        console.log("PDU", pdu);
        if (pdu.command_status == 0) {
            // insert into sms smpp logs
            var values = {
                type: 'bulk',
                message: text,
                numbers: JSON.stringify(to)
            };

        console.log(pdu.message_id);
            callback(null, pdu.message_id);
        }
    });
};

如果messege的字符数少于160个，则表示是好的.将发送消息，但如果messege的字符数超过160个字符，则如果sms messege的时间太长，它将在buffer.js中抛出新的TypeError值参数. .非常感谢您的帮助

If the messege is below 160 character it is okey .Messege will be sent but if messege is above 160 character then it will throw new TypeError value argument is out of bounds in buffer.js if sms messege is too long.Please Help .will really appreciate any help

npm install gsm
The above module also splits the message into parts:

//We need to split the message and send it in many parts
var gsm = require('gsm');

var info = gsm("Your message string here");

//This is a unique id present in each message part
var concat_ref = this.concat_ref++; 

var part_id = 0;
info.parts.forEach(function(part) {
    part_id++;
    var udh = new Buffer(6);
    udh.write(String.fromCharCode(0x5), 0); //Length of UDF
    udh.write(String.fromCharCode(0x0), 1); //Indicator for concatenated message
    udh.write(String.fromCharCode(0x3), 2); //  Subheader Length ( 3 bytes)
    udh.write(String.fromCharCode(concat_ref), 3); //Same reference for all concatenated messages
    udh.write(String.fromCharCode(info.sms_count), 4); //Number of total messages in the concatenation
    udh.write(String.fromCharCode(part_id), 5); //Sequence number ( used by the mobile to concatenate the split messages)

    var submit_pdu = {
        source_addr:msg.from,
        destination_addr: msg.to,
        short_message: { udh:udh, message:part },
        registered_delivery:1 //If you want a delivery report
    };

    this.getSession().submit_sm(submit_pdu, function(pdu) {
        if (pdu.command_status == 0) {
            console.log("SMPP Gateway[" + this.getOptions().address + "] - SUMBIT[" + submit_pdu.source_addr + ">>>" + submit_pdu.destination_addr + "] - " + pdu.message_id);
        }
        if(callback) {
            callback(pdu);
        }
    }.bind(this));
}.bind(this));
