node.js - BodyParser data is undefined after AJAX call -

-

the body parser body {}. i've done research , made sure ajax data key set correctly make sure middleware set correctly well. here frontend ajax call

$.ajax({ type:"get", url:"/api", data: {course:"math-226"}, success: function(data){ alert(data);} });

and here backend server.js file:

'use strict' const express = require('express'); const path = require('path'); const bodyparser = require('body-parser'); const alg = require('./app/algorithm.js'); const app = express(); app.use('/', express.static(path.join(__dirname, 'public'))); app.use(bodyparser.json()); app.use(bodyparser.urlencoded({extended: true}));  app.get('/api', (req, res) => { console.log(req.body); alg.create(req.body.course, answer => res.send(answer)); }); let server = app.listen(3000, () => {   let host = server.address().address;   let port = server.address().port;   console.log('example app listening @ http://%s:%s', host, port); });

you using request, it's not being sent. if need send something, can attach header or include in query string of url. if want send data, use post request.
