目前还没有获得live-player的使用权限，手机打开调试模式应该也是能调试的。

===============wxml:

<live-player id="livePlayer" mode="live" autoplay src="{{playUrl}}"></live-player>

<view class="ver-hor disfr" bindtap="verHorSwitch">

<label class="iconfont icon-quanping" wx:if="{{!playFullScreen}}"></label>

<label class="iconfont icon-tuichuquanping" wx:if="{{playFullScreen}}"></label>

</view>

===============js:

verHorSwitch() {

        this.livePlayerContext = this.livePlayerContext ? this.livePlayerContext : wx.createLivePlayerContext('livePlayer', this)

        const that = this

        console.log('livePlayerContext：' + this.livePlayerContext) // 此处打印已获取到实例

        this.livePlayerContext.requestFullScreen({

            direction: 90,

            success(res){

                console.log(res)

                that.setData({

                    playFullScreen: true

                })

            },

            fail(err){

                console.log(err, 'err')

            },

            complete(e) {

                console.log(e, 'e')

            }

        })

}
