ps:拿到手机的高度、宽度、高宽比例，自定义页面模块的高度和间距。
主要代码：
<view class="cono" :style="{height:navHeight3+‘rpx‘}"> </view> <view class="banner" v-if="navHeight4==370" style="background:url(‘../../static/img/baindex_370.png‘) no-repeat ;height: 180px;background-size:750rpx ;"> </view>
<view class="contt" :style="{backgroundImage: ‘url(‘ + imageURL + ‘)‘, ‘background-repeat‘:‘no-repeat‘, backgroundSize:‘100% 100%‘,height:‘‘+mobileHeight+‘px‘}"> </view>
