微信小程序：设置启动页

今天写的时候，发现微信小程序开发者平台无法显示出我们正在编写的页面，这对需要看效果的我们很是无奈，只好百度去设置首页，百度后的结果是在app，json中设置首页，很简单，只要在page中第一个就默认是首页了

{
  "pages":[
    "pages/list_trains/list.train",
    "pages/index/index",
    "pages/logs/logs"
  ],

{
  "pages":[
    "pages/list_trains/list.train",
    "pages/index/index",
    "pages/logs/logs"
  ],

{
  "pages":[
    "pages/list_trains/list.train",
    "pages/index/index",
    "pages/logs/logs"
  ],
