//生成AMP版本 用移动端版本生成
/*
1.加载站点AMP模板，模板只有导航、头部、底部
2.删除全部js引用和内链代码
3.删除全部css引用，内联css放入<style amp-custom>
4.图片全部替换成amp-img，设置宽高，设置layout="responsive"
5.去掉所有元素中的style
6.去掉样式表中的!important
7.替换读取源文件title description keywords canonical
8.todo:增加application/ld+json
要求: 图片文件必须带有域名，否则的获取尺寸会出错，如 https://data.asiahighlights.com/pic/abc.jpg
