[jpaul55]

Hi, Thank you for the module. just want to ask why do I cant get a response for this line of code. even a console .log

bot.on(LINEBot.Events.MESSAGE, function(replyToken, message) { // add code below. console.log('Test'); });

I want to see before this code. thank you

[jpaul55]

Thank you for the reply, this is the code. Am I missing something? my webhook url. is like this. https://line-webhook-demo.herokuapp.com

var app = require('express')();
var server = require('http').Server(app);

var LINEBot = require('line-messaging');
var request = require('request');
var rp = require('request-promise');

var bot = LINEBot.Client({
  channelID: '15', //edited
  channelSecret: '1c63', // edited
  channelAccessToken: 'Fej+fG2APtoM9jFgCK/1zp8dXM2n1XnhxYt+lQyUS68+R+Qp6lZV8VFdaQ89yUx9ELVktzn9f3z9Bim5lMjWMWc13xOeQdB04t89/1O/w1cDnyilFU=' // edited
}, server);

app.use(bot.webhook('/'));

bot.on(LINEBot.Events.MESSAGE, function(replyToken, message) {
  // add code below
  console.log('dfsdfsdfsdfsdfsdfsdfdsfdsfsdfsdfsdfsdfsdfsdf' + replyToken);
});
server.listen(process.env.PORT || 5000, () => {
    console.log(`server is listeninssssg to ${process.env.PORT || 5000}...`);
});

If you use line-messaging version 1.2.0 please change code

var app = require('express')();
var LINEBot = require('line-messaging');

var bot = LINEBot.Client({
    channelID: '<your channel ID>',
    channelSecret: '<your channel secret>',
    channelAccessToken: '<your access token>'
});

app.use(bot.webhook('/'));
bot.on(LINEBot.Events.MESSAGE, function(replyToken, message) {
    console.log('messsage', message.getText());
});

app.listen(8080);

I'm sorry, I not change README.md some code. Thank you.

Awesome! Thank you for the reply. It works now. however how can I set a condition for the replyTextMessage.

this code doesnt work if I put an if condition inside bot.on event.

bot.on(LINEBot.Events.MESSAGE, function(replyToken, message) {
  // add code below.
 console.log('messsage', message.getText());
 console.log(replyToken)
var resp;
if(message.getText() == "hello world"){
  resp = "hi your awesome";
}else{
 resp = "still awesome";
}
 bot.replyTextMessage(replyToken, resp).then(function(data) {
  // add your code when success.
  console.log(data);
}).catch(function(error) {
  // add your code when error.
 });
});

Please check settings on your console https://developers.line.me/console/ my code (sent 'hello world' and received 'hi your awesome') and I test it.

var msg = message.getText();
var resp = '';
if (msg === 'hello world') {
    resp = 'hi your awesome';
} else {
    resp = 'still awesome';
}

bot.replyTextMessage(replyToken, resp).then((data) => {
    console.log(data);
}).catch((error) => {
    console.error(error);
});

Thank you snlangsuan. Im able to see the message now, however replyToken has a limit? because sometimes it works and sometimes it doesnt. This is the reply from my logs.

It replyToken becomes invalid after a certain period of time, If you has process (long time) before sent message, Please use:

var userId = message.getUserId();
bot.pushTextMessage(userId, 'hello!');

You can find more information from Messaging API

[jpaul55]

hi snlangsuan, using message.getUserId() doesnt work all the time. maybe this has something to do with my webhook because sometimes it works and sometimes it does not,

[snlangsuan]

It module follows the LINE Messaging API, Some action not response userId
