			小程序中__wxConfig.envVersion可以用来区分小程序体验版，开发板，正式版.
			envVersion 类型为字符串
			envVersion: 'develop',    //开发版
			envVersion: 'trial',          //体验版
			envVersion: 'release',     //正式版
			这样我们就可以变通的来实现小程序中动态切换域名,避免手动注释切换的方式.
			
			<!-- request.js -->
			let envVersion = __wxConfig.envVersion || 'develop';
			const url = envVersion === 'develop' ?  Store.state.testUrl ? Store.state.baseUrl
