Applet parameters micro letter how successful the interface calls the callback function returns return out? (Promise can be resolved !!)

For chestnut
 // Get application examples
//const app = getApp()
// const util = require ( '../../ utils / util.js')
//const sign = util.sign
//var Md5 = require('../../utils/md5.js');
