小程序自带组件live-player并没有提供全屏按钮，需要自己手写全屏和退出全屏

实现思路：点击视频 显示放大图标 点击放大和缩小图标 调用对应api

代码
wxml

<view bindtap="showFull">
  <view class="live-video" bindtap="showFull">
    <live-player id="livePlayer" src="rtmp://devlivepull.migucloud.com/live/05XP3YWQ_C0" mode="live" autoplay bindstatechange="statechange" binderror="error">
      <view class='full_img_idv' catchtap="hideFull" wx:if="{{showControls}}">
        <view class="col-box" bindtap="unFullScreen" wx:if="{{fullScreenFlag}}">
          <image src="../images/unfold.png" class='full_img' />
        </view>
        <view class="col-box" wx:else bindtap="onFullScreen">
          <image src="../images/fold.png" class='full_img' />
        </view>
      </view>
    </live-player>
  </view>
</view>

js

Page({
  data: {
    fullScreenFlag: false,
    showControls: false,
    LivePlayerContext: ''
  },
  onl oad() {

  },
  showFull() {
    this.setData({
      showControls: true
    })
  },
  hideFull() {
    this.setData({
      showControls: false
    })
  },
  onFullScreen() {
    let that = this
    this.data.LivePlayerContext = wx.createLivePlayerContext('livePlayer')
    this.data.LivePlayerContext.requestFullScreen({
      direction: 90,
      success(e) {
        that.setData({
          fullScreenFlag: true
        })
      },
      fail(e) {
        console.log(e)
      },
      complete(e) {
        console.log(e)
      }
    })
  },
  unFullScreen() {
    let that = this
    this.data.LivePlayerContext.exitFullScreen({
      success(e) {
        that.setData({
          fullScreenFlag: false
        })
      },
    })
  },
  statechange(e) {
    console.log('live-player code:', e.detail.code)
  },
  error(e) {
    console.error('live-player error:', e.detail.errMsg)
  }
})
