requestFullScreen 在开发者工具上会同时执行2次，真机下无效： 代码如下 videoFullscreenchange(e: any){       console.log('eeee',e)       let {fullScreen} = e.detail       this.setData({         fullScreen: fullScreen       })       if(!fullScreen){         let video: any = this.data.video         video.pause()       }     },     videoPlay(e : any){       let {videoid} = e.currentTarget.dataset       let video: any = wx.createVideoContext(videoid, this);       console.log(videoid)       setTimeout(() => {         video.requestFullScreen({           direction: 0,         })       }, 500)       this.setData({         video: video,         fullScreen: true       })       video.play()    }  输出结果 [图片]
