使用AJAX调用Node.js文件发送短信

Question

I'm new to Node.js but I understand that it's on the server-side. When I run my app.js file in Terminal, it sends the text message, but what I'm ultimately trying to do is have the user finish the form, and upon button press, send them a text message to verify their submission. I'm using the Twilio service to help accomplish this. It's currently not sending a message on button press.

Here's my app.js file:

var accountSid = process.env.TWILIO_ACCOUNT_SID;
var authToken = process.env.TWILIO_AUTH_TOKEN;
var client = require('twilio')(accountSid, authToken);

app.get('/testtwilio', function(req, res) {
  client.messages.create({
    to: "+1receivingNumber",
    from: "+myTwilioNumber",
    body: "Testing, testing, testing"
  }, function(err, message) {
    if (err) {
      console.log(err);
    } else {
      console.log(message.sid);
    }
  });
})  

And my Javascript file:

$('#buttons').on('click', function(e) {
  $.ajax({
    type: 'POST',
    url: '/testtwilio',
    data: {
      "To": userCellPhone,
      "From": "+1myTwilioNumber",
      "Body": "Ahoy! Testing"
    },
    beforeSend: function(xhr) {
      ...
    },
    success: function(data) {
      console.log(data);
    },
    error: function(data) {
      console.log(data);
    }
  });
});

And lastly, my html button:

<button type="submit" id="buttons" class="buttons">SUBMIT</button>

Honestly, I'm not even sure this is possible, but I've been searching forever and can't really find any direct solution. Any help is appreciated!

Answer 1

Your app variable is undefined. If you want to use the express framework like in the tutorials you've followed, you need to register it in your app.js like follows:

var express = require('express');
var app = express();

Combined with the answers/comments about POST, that should see you on your way.

Nb. you'll need to install express in your node modules. From the command line in your root directory:

npm install --save express

Answer 2

nodeJs route expects GET. But your ajax makes POST request. Try:

app.post('/testtwilio', ...
