if(src){

            this.setData({

                videoSrc: baseSrc + src,

                initTime: res.data.playTimePoint

            })

            if(isend){

                console.log('走到这儿了吗');

                let videoContext = wx.createVideoContext(this.data.currentCourse.id);

                videoContext.play();

                console.log('videoContext',videoContext);

            }

        }

前后都打印出来了，但是没有播放效果
