接下来实现将歌曲信息添加到数据库
1.我们先要定义好结构，在我们之前通过express xxx构建的项目中定义一个models文件夹，创建一个music.js文件，写入以下代码
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
// 定义表结构
var musicObj = new Schema({
song_id: String,
author: String,
title: String,
hot: String
});
module.exports = mongoose.model('musics',musicObj);//暴露出去
2.在我们的routes文件夹下创建一个music.js文件，写入以下代码
var express = require('express');
var Router = express.Router();
//引入刚刚暴露出来的表模型
var musicModel = require('../models/music');
//定义添加到收藏的接口
Router.post('/collect',function(req,res,next){
// 这里是post请求，使用req.body来获取前端传过来的数据
let musiCollect = new musicModel({
song_id: req.body.song_id,
author: req.body.author,
title: req.body.title,
hot: req.body.hot
});
// 保存
musiCollect.save(function(err,doc){
if(err) {
res.json({
states: 0,
msg: err.message
});
}else {
res.json({
states: 1,
msg: '保存成功'
});
}
});
});
//查询收藏的数据
Router.post('/list',function(req,res,next){
musicModel.find({},function(err,doc){
if(err) {
res.json({
states: 0,
msg: err.message
});
}else {
res.json({
states: 1,
msg: doc //查询到的数据，以json格式返回
});
}
});
});
module.exports = Router;//暴露出路由
3.在app.js里面引入暴露出的路由var musicRouter = require('./routes/music');
4.使用该路由app.use('/music', musicRouter);
5.这样我们就可以在前端通过/music/collect来请求我们的添加收藏接口
6.这里需要注意的是前端的端口是8080，后端是3000所以存在跨域问题，在vue项目的config文件夹下有个index.js文件，将反向代理加上
//这里的意思是凡是以/music开头的接口都会指向3000的端口
proxyTable: {
'/music/*':{
target: 'http://localhost:3000'
}
},
7.注意的是这里的配置文件修改后的重启服务
8.先引入import axios from "axios"，这里不知道的可以先了解下vue的基础知识，你也可以用vuex来封装这些请求，这里就不做介绍
// 添加到收藏
addMusic(item) {
let datas = {
song_id: item.song_id,
author: item.author,
title: item.title,
hot: item.hot
}
axios.post('/music/collect',datas).then(data=>{
this.$message({
message: '收藏成功',
type: 'success'
});
})
},
9.如果你使用mongoVUE就可以看到数据已经保存成功

这样首页的列表和查询接口实现完了，添加到数据库也实现了，下面是music.vue的全部代码
