vue從數(shù)據(jù)庫讀取數(shù)據(jù)失敗

1、vue頁面是一張表格，表格數(shù)據(jù)從數(shù)據(jù)庫讀取，現(xiàn)在讀不到數(shù)據(jù)。

2、數(shù)據(jù)庫連接成功：

但是界面報錯如下：

3、鏈接數(shù)據(jù)庫代碼結(jié)構(gòu)和代碼：

db.js

// 數(shù)據(jù)庫連接配置
module.exports = {
    mysql: {
        host: '123.139.88.227',
        user: 'campus',
        password: 'root',
        database: '***',
        port: '33061'
    }
}

index.js

const userApi = require('./api/newStuApi');
const fs = require('fs');
const path = require('path');
const bodyParser = require('body-parser');
const express = require('express');
const app = express();

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));

// 后端api路由
app.use('/api/newStu', userApi);

// 監(jiān)聽端口
app.listen(3306);
console.log('success listen at port:3306......');

sqlMap.js

/**
 * Created by Administrator on 2017-11-15.
 */
// sql語句
var sqlMap = {
    // 用戶
    newStu: {
        search: 'select NAME,YEAR,ENROLL_TYPE,MAJOR_CODE,EXAM_NUMBER,MOBILE_PHONE,TELEPHONE,ADDRESS FROM EM_NEW_STUDENT '
    }
}

module.exports = sqlMap;

測試代碼，在界面點擊“查詢”`

getList() {
                this.listLoading = true;
                var NAME = this.NAME;
                var YEAR = this.YEAR;
                var ENROLL_TYPE = this.ENROLL_TYPE;

                var MOBILE_PHONE = this.MOBILE_PHONE;
                var TELEPHONE = this.TELEPHONE;
                var ADDRESS = this.ADDRESS;
                this.$http.get('/api/newStu/searchNewStu', data => {
                    this.$set('NAME', data.NAME);
                    this.$set('YEAR', data.YEAR);

                    this.$set('TELEPHONE', data.TELEPHONE);
                    this.$set('ADDRESS', data.ADDRESS);
                }).then((response) => {
                    console.log(response);
                })
                /* fetchList(this.listQuery).then(response => {
                    this.list = response.data.items
                    this.total = response.data.total
                    this.listLoading = false
                })*/
            },
            /* 查詢*/
            handleSearch() {
                this.listQuery.page = 1
                this.getList()
            },
