录音文件上传到服务器后然后再下载调用playVoice播放没有声音 - WXOPEN Club

play: function (e) {

var path = e.target.dataset.path;

var that = this

that.setData({

ifplay:false

})

wx.downloadFile({

url: path,

success: function (res) {

console.log("download tmpfile path is:",res.tempFilePath)

wx.playVoice({

filePath: res.tempFilePath,

success:function(){

console.log('play voice success')

},

fail:function(errMsg){

console.log('play file fail, errMsg is', errMsg)

},

complete:function(){

console.log('play voice complete')

that.setData({

ifplay:true

})

}

})

},

fail: function (errMsgres) {

console.log('download file fail, errMsg is', errMsg)

}

})

}

模拟器环境调试，录音文件已成功上传到后台，下载完后后播放下载的录音文件会触发success()和complete()方法，但是没有声音，而且success()和complete()方法是很快触发的，就像播放了一下立刻就结束了。

下面是控制台输出
