Problems POSTing json to Node/Express server from Axios/React - node.js

Question

I'm current working on a web application using Node.js with Express in the back-end and React.js in the front end. In attempting to post user data to the Node server, through axios, I am running into an issue. When I make a post with the x-www-form-urlencoded content type, the front end will post to the server but the entire JSON of the posted data appears in the key field of the first element. When I change the content type to json it stops posting anything from the front end. I have tried cUrling to the server, and curling a JSON post will get accepted by the server.
React code to post to server
handleSubmit()
{
var form=this;
var axiosConfig = {
headers: {
'content-type': 'application/json; charset=utf-8'
}
}
axios.post('http://localhost:8080/api/login/', {
'username': form.state.username,
'password': form.state.password
}, {headers: {'content-type': 'application/json'}});
};
Server code for api endpoint
//From server.js
const express=require('express');
const session=require('express-session');
const bodyParser=require("body-parser");
const path = require('path');
var login = require('./routers/login')
var port = process.env.PORT || 8080;
var app=express();
app.use(session({'secret': 'thealphabetbackwardsiszyxwvutsrqponmlkjihgfedcba'}));
app.use(bodyParser.urlencoded({ extended: true}));
app.use(bodyParser.json());
//...
app.use('/api/login', login);
//from login.js
/* Router for login system
When user attempts to log in, check their credentials
If the user successfully logs in, create a session
If user enters invalid credentials prompt them
*/
const path = require('path');
const bodyParser = require('body-parser');
const mongoose = require('mongoose');
const user = require("./../models/UserSchema")
mongoose.connect('mongodb://localhost/newt');
const express = require('express');
const router = express.Router();
router.get('/', function (req, res)
{
console.log("Test");
})
router.post('/', function(req, res)
{
console.log(req.body);
res.end();
})
// To create test user use path localhost:8080/api/login/testing
router.get('/test', function (req, res)
{
var db = mongoose.connection;
var test = new user({
username: "joesephschomseph",
email: "testUser#test.com",
fname: "Joe",
lname: "Schmoe"
})
test.save();
console.log("Created test user!");
});
module.exports = router

npm install --save const body-parser
in app.js include const bodyparser = require('body-parser');
app.use(bodyparser.urlencoded({ extended: false }));
app.use(bodyparser.json());
remove the single quotes from your 'username' and 'password'
console.log(req.body);
