同问

function play(url) {

    wx.playBackgroundAudio({

        dataUrl: url

    });

    console.log(url);

    wx.onBackgroundAudioStop(function () {

        wx.playBackgroundAudio({

            dataUrl: url

        });

    });

}

下载的临时文件不能播放？

我在console里面打出来点击链接可以播放，但是调用play方法不能播放

playVoice 只能播放录音文件
