仿网易云音乐-微信小程序开发

1.很多时候要找到完整的API接口很难，但网易云音乐的数据API是可以得到完整的。

安装API：https://github.com/Binaryify/NeteaseCloudMusicApi，只需按照步骤部署就可以的。

提示：由于本地电脑环境千差万别，建议会使用virtualBox虚拟机进行部署可一劳永逸

部署完成，   cd NeteaseCloudMusicApi node app.js   开启服务即可

 2.根据相关API开发页面

获取推荐歌单列表

 tabBar,主页面色，以及路由设计

{
  "pages": [
    "pages/home/home",
    "pages/hot/hot",
    "pages/search/search",
    "pages/listdetail/listdetail",
    "pages/musicplay/musicplay"

  ],
  "window": {
    "backgroundColor": "#F6F6F6",
    "backgroundTextStyle": "light",
    "navigationBarBackgroundColor": "#d43c33",
    "navigationBarTitleText": "网易云音乐",
    "navigationBarTextStyle": "white"
  },
  "tabBar": {
    "backgroundColor": "#212121",
    "color": "#8F8F8F",
    "selectedColor": "#FFF",
    "list": [{
      "pagePath": "pages/home/home",
      "text": "推荐音乐",
      "iconPath": "/images/cm2_btm_icn_discovery.png",
      "selectedIconPath": "/images/cm2_btm_icn_discovery_prs.png"
      
    },
    {
      "pagePath": "pages/hot/hot",
      "text": "热歌榜",
      "iconPath": "/images/cm2_btm_icn_radio.png",
      "selectedIconPath": "/images/cm2_btm_icn_radio_prs.png"
    },
    {
      "pagePath": "pages/search/search",
      "text": "搜索",
      "iconPath": "/images/cm2_btm_icn_music.png",
      "selectedIconPath": "/images/cm2_btm_icn_music_prs.png"
    }
    ]
  },
  "requiredBackgroundModes": ["audio", "location"],
  "sitemapLocation": "sitemap.json"
}

 "requiredBackgroundModes": ["audio", "location"],

若需要在小程序切后台后继续播放音频，需要在 app.json 中配置 requiredBackgroundModes 属性。

获取API数据，此时有两种方法，使用小程序云函数，或者本地获取

本地获取：
封装request请求get，post

const baseurl = 'http://localhost:3000'
function getbaseurl() {
  return baseurl;
}
//get请求
function get(url, data) {
  return new Promise((reslove, reject) => {
    wx.request({
      method: 'GET',
      url: baseurl + url,
      data,
      success: reslove,
      fail: reject
    })
  })
}

//post请求
function post(url, data) {
  return new Promise((reslove, reject) => {
    wx.request({
      method: 'POST',
      url: baseurl + url,
      data,
      success: reslove,
      fail: reject
    })
  })
}

//需要导出
module.exports = {
  get,
  post,
  getbaseurl
}

// pages/home/home.js
var requestUrl = require('../../utils/request.js')
Page({

  /**
   * 页面的初始数据
   */
  data: {
      musicList: [ ],
      detailUrl:''
  },

  /**
   * 生命周期函数--监听页面加载
   */
  onLoad: async function (options) {
    const res = await requestUrl.get('/personalized/?limit=6')
     this.setData({ musicList: res.data.result});
    console.log(res.data.result)
  },

自定义组件还可以自己触发双向绑定更新，做法就是：使用 setData 设置自身的属性

<wxs module="common" src="../../utils/utils.wxs"></wxs>
<view class="m-homeremd">
<h2 class="remd_tl"> 推荐歌单</h2>
    <view class="remd_ul">
        <navigator url="../listdetail/listdetail?id={{item.id}}" class="remd_li"  data-musicid="{{item.id}}" wx:for="{{musicList}}" wx:key="index">
          <view class="remd_img">
            <image class="u-img" src="{{item.picUrl}}"></image>
            <span  class="u-earp remd_lnum">{{common.numberFormat(item.playCount)}}</span>
          </view>
          <text class="remd_text">{{item.name}}</text>
        </navigator>
    </view>
</view>

推荐歌单页面有一个播放量转换

{{common.numberFormat(item.playCount)}}

function numberFormat(value) {
    var param = {};
    var k = 10000,
      sizes = ['', '万', '亿', '万亿'],
      i;
    if (value < k) {
      param.value = value
      param.unit = ''
    } else {
      i = Math.floor(Math.log(value) / Math.log(k));

      param.value = ((value / Math.pow(k, i))).toFixed(2);
      param.unit = sizes[i];
    }
  return param.value + param.unit;
  }
module.exports = {
  numberFormat: numberFormat
}

列表页面渲染：根据id值跳转到相对应的列表页面

<navigator url="../listdetail/listdetail?id={{item.id}}" class="remd_li"  data-musicid="{{item.id}}" wx:for="{{musicList}}" wx:key="index">

import {get} from "../../utils/request.js"

Page({

  data: {

  },

  /**

  onLoad: async function (options) {
    console.log(options)
    const url =`/playlist/detail?id=${options.id}`
    const res = await get(url)
    console.log(res.data)
    this.setData({ detailList: res.data.playlist})
    
  },
