小程序语音（A）发给别人(B)，也能播放，是需要先把语音上传到自己的服务器上才可以。

A端：

Wxml:

<button wx:if="{{selected}}" bind:touchstart="start" bind:touchend="stop" data-index="{{index}}" data-member>

Js:

定义公用语音包组件

const recorderManager = wx.getRecorderManager();

const innerAudioContext = wx.createInnerAudioContext();

//开始录音的时候

start: function() {

const options = {

duration: 10000, //指定录音的时长，单位 ms

sampleRate: 16000, //采样率

numberOfChannels: 1, //录音通道数

encodeBitRate: 96000, //编码码率

format: \'mp3\', //音频格式，有效值 aac/mp3

frameSize: 50, //指定帧大小，单位 KB

}

//开始录音

recorderManager.start(options);

recorderManager.onStart(() => {

console.log(\'开始录音\')

});

//错误回调

recorderManager.onError((res) => {

console.log(res);

})

},

//停止录音

stop: function(e) {

var that = this;

var memberid= e.currentTarget.dataset.memberid;

recorderManager.stop();

recorderManager.onStop((res) => {

var list = that.data.vediolist;

var start = this.data.start;

var end = e.timeStamp;

var seconds = (end % (1000 * 60)) / 1000;

var shijian = seconds - start;

//这里也能按照时间显示留言宽度，暂时没做

var src = res.tempFilePath; //语音临时文件

//先把语音上传到自己的服务器上才可以，然后把返回的语音放入数组存储，最后在一起存到数据库中的字段里

wx.uploadFile({

url: hcxcx.apiUrl.getuploadvedio,

filePath: src,

header: {

\'content-type\': \'multipart/form-data\'

},

success: function(res) {
