微信小程序环境识别

const accountInfo = wx.getAccountInfoSync();
accountInfo.miniProgram.envVersion会有三个值：

• develop：开发版（正常开发工具，测试时）
• trial：体验版
• release：正式版

onLaunch() {
   const accountInfo = wx.getAccountInfoSync();
   switch (accountInfo.miniProgram.envVersion) {
     case 'develop':
         //dosomething
       break;
     case 'trial':
         //dosomething
       break;
     case 'release':
         //dosomething
       break;
     default:
         //dosomething
       break;
   }
   console.log(accountInfo)
 }
