1. 分包加载
修改app.json，增加subPackages字段，大概长这样：
"subPackages": [ { "root": "pages/cfs/", "pages": [ "main", "query/main", "photograph/main", "packing/main", "pin/main", "pin/detail/main" ] }, { "root": "pages/check/", "pages": [ "main", "detail/main" ] }]复制代码我的项目目录是这样的：
2. 图片require
分包之后发现主包还是太大了/(ㄒoㄒ)/~~，之前就觉得应该是我的图片太多了，并且是直接在src里引入的，那么就修改为用require()来引入图片资源：
{ imgUrl: require('../../assets/images/home/cfs.png'), text: ''}, { imgUrl: require('../../assets/images/home/gate.png'), text: ''}, { imgUrl: require('../../assets/images/home/bay.png'), text: ''}, { imgUrl: require('../../assets/images/home/check.png'), text: ''}复制代码结果真的主包就变小了哈哈哈哈
