如何检索node.js中.ajax请求中传递的数据？

Question

我正在尝试将我从主页javascript index.ejs传递的数据检索到routes / index.js中的函数

index.ejs

$(".user-create-btn").click(function(e){
    $.ajax({
        url: "/users/create/",
        data: {username: "John123"},
        type: "post",
        dataType : "json",
        success: function(result) {
            console.log("test")
        }
    });
    e.preventDefault(e);
    location.reload();
  });

路由/ index.js

/*Create new user*/
router.post('/users/create', (req, res) => {
  //how can i retrieve the the data of the username here?
  models.User.create({
    username: username,
  })
});

Answer 1

var express = require('express')
    , router = express.Router()
    , bodyParser = require('body-parser')

var app = express();
app.use(bodyParser.json());

router.post('/users/create', (req, res) => {
  var body = req.body,
    username = body.username;

  models.User.create({
    username: username,
    ...
  })
});

app.use(router);

var http = require('http');
var server = http.createServer(app);
server.listen(3000);
