前端

错误1 发送没有反应，觉得是地址不对，老师上课有改，但是找不到。

查了以前的是mui.post处，但是是window.serv，本以为是系统自动检测，

但是也不可能是监测到9527吧，

从网上https://www.cnblogs.com/wen-kang/p/10778812.html博客里找到：

为了避免hbuilder中的js频繁的给后端发送AJAX，更换ip,可以将ip设置为全部变量，在引用文件的js文件添加代码如下：

window.serv="http://192.168.1.114:9527";

extras:{
      .....//自定义扩展参数，可以用来处理页面间传值
    },

前端的音乐播放的哪里的资源？

数据库里没有给传过去MP3！

<button type="button" class="mui-btn mui-btn-green mui-btn-block" id="resume">继续</button>
var Sdata = null;					#通过plus.webview可获取应用界面管理对象。
Sdata = plus.webview.currentWebview();	#获取当前窗口的WebviewObject对象
 
document.getElementById("title").innerText = "正在播放       " + Sdata.title;
ap = plus.audio.createPlayer(window.music_serv + Sdata.music);	# 括号里的‘xx.MP3’从哪里来	‘http://192.168.12.70:9527/get_music/’
ap.play();

document.getElementById('resume').addEventListener('tap', function() {
				ap.resume();	
			});

mui.js 里有配置参数

window.serv = "http://192.168.12.70:9527";
window.ws_serv = "ws://192.168.12.70:9527/app/";
window.image_serv = window.serv + "/get_cover/";
window.music_serv = window.serv + "/get_music/";	

播放的是 这里的 send_file

@content_bp.route('/get_music/<filename>',methods=['GET'])
def get_music(filename):

    music_path = os.path.join(MUSIC_PATH, filename)
    return send_file(music_path)	

数据如下：应该是data.DATA data是 auto.login 传过来的数据 fuc(data)

 [{"_id":"5d32b0839c057a77211fad55","cover":"c6b68f04-9a4c-46b6-9560-0bb31c38c7b7.jpg","music":"c6b68f04-9a4c-46b6-9560-0bb31c38c7b7.mp3","title":"新年恰恰","zhuanji":"【一千零一夜】经典儿歌"},..........{"_id":"5d32b0839c057a77211fad68","cover":"17e969d0-6e37-4438-a877-e2240e191984.jpg","music":"17e969d0-6e37-4438-a877-e2240e191984.

stada.music : "music":"c6b68f04-9a4c-46b6-9560-0bb31c38c7b7.mp3"

sdata的值 plus.webview.currentWebview();？不是等于创建一个窗口吗？

{"__view_array__":[],"__IDENTITY__":"NWindow","__uuid__":"NWindow91563607904411","__callbacks__":{"back":[null],"menu":[null]},"__callback_id__":"plus41563607905521","id":"player.html","music":"c6b68f04-9a4c-46b6-9560-0bb31c38c7b7.mp3","title":"新年恰恰","cover":"c6b68f04-9a4c-46b6-9560-0bb31c38c7b7.jpg","zhuanji":"【一千零一夜】经典儿歌","_id":"5d32b0839c057a77211fad55"} at player.html:58

访问这个网址，就可以播放音乐，后端开启的状态下。这里面存了send_file的MP3

http://192.168.12.70:9527/get_music/e87e08f5-28e9-493f-8f5a-15ef02d3abc6.mp3

所以

ap = plus.audio.createPlayer(window.music_serv + Sdata.music); 'h://..xx.mp3'

就可以播放了（没有点击事件，只不过是后端传到网络上的资源）

Sdata 
console.log('sdata:', Sdata)--->  sdata: at player.html:49  是这个？
