wx.downloadFile({ url:"http://123.206.192.155/files/music/341_002_01.mp3", success:function(res){ wx.playVoice({ filePath: res.tempFilePath, success:function(e){ console.log(res.tempFilePath) console.log(e) }, fail: function () { console.log("播放失败") } }) } }) 这是代码 日志： {tempFilePath: "wxfile://tmp_250646293o6zAJs779AehKefPJq2Gl_1PFov498d192d8a1f33a9e337274a935febea6.mp3", statusCode: 200, errMsg: "downloadFile:ok"} lesson1.js? [sm]:110 {errMsg: "playVoice:ok"} 都是ok的，就是没声音，有大神来解答下
