Javascript 通过节点服务器插入数据时出错

我试图通过JSON主体将数据插入MySQL服务器。 但是插入的数据是未定义的格式。 我无法找到它发生在nodejs简单基础项目上的原因是什么

Mysql帮助文件

var mysqlHelper = require('../common/mysqlconn');
function adduser(req, res) {
var data = req.body;
var query = "insert into user_master(name,phonenumber) values ('" + data.name + "','" + 
data.phonenumber + "')";

mysqlHelper.excecuteQuery(query, function (err, result) {
    if (err) {
        res.json({
            success: false,
            err: err
        })
    }
    else {
        res.json({
            success: true,
            message: "Record inserted successfully"
        })
    }
 })
}

module.exports = {
adduser: adduser
}

var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var port = process.env.PORT || 5300; // used to create, sign, and verify tokens
var path = require('path');
app.use(bodyParser.urlencoded({
extended: false
}));
app.use(bodyParser.json({
limit: 1024102420,
type: 'application/json'
}));
var user = require('./route/user.route');
app.use('/', express.static(path.join(__dirname, 'public')))
app.use('/user', user);
var server = app.listen(port);
console.log('Server running at http://localhost:' + port);
