调用 wx.getRecorderManager().start() 开始录音，

onError得到错误信息：errMsg: opreateRecorder fail: start record fail.

此报错在真机调试时会出现，在小程序开发工具里不会出现。真机上确定已经开通了录音权限。

调用代码如下：

if(wx == undefined || wx)

{

console.log("record onLoad...")

var obj = {}

obj.sampleRate = 8000

obj.encodeBitRate = 16000

obj.numberOfChannels  = 1

obj.format = "acc"

obj.frameSize = 0.1

wx.getRecorderManager().start(obj)

console.log("record start...")

wx.getRecorderManager().onStart(

function ()

{

console.log("record started...")

}.bind(this)

)

wx.getRecorderManager().onError(

function (errMsg)

{

console.log("error...", errMsg)

}.bind(this)

)

wx.getRecorderManager().onFrameRecorded(

function (frameBuffer,isLastFrame)

{

console.log("record...")

}.bind(this)

)

}
