云函数的实现部分： await openapi.security........这里的openapi有引入或声明吗？

这个js文件require了urlencode，然后被页面的index.js引用 const md5 = require('./md5.js'); const urlencode = require('urlencode'); const sortData = function (data) {   let keys = Object.keys(data).sort();   let result = {}   for (let i = 0; i < keys.length; i++) {     let value = data[keys[i]]     if (value instanceof Object) {       value = sortData(value)     }     result[keys[i]] = value   }   return result; } const makeUrl = function (method_tag, params) {   console.log('Call makeUrl:', method_tag, params)   let time = (new Date()).valueOf();   let token = 'test';   let tag = method_tag;   let params_str = JSON.stringify(sortData(params))   let sign_data = 'createTime=' + time + 'params=' + params_str+'tag='+tag+'token='+token;   let url = 'http://qae.qunar.com/api/router?';   let createTime = time;   let sign = md5.md5(sign_data).toLowerCase();   console.log(sign_data, sign.toLowerCase())   params_str = urlencode(params_str);   return url + 'token=' + token + '&tag' + method_tag + '&token' + token + '&createTime' + time + '&params' + params_str; } module.exports = {   makeUrl: makeUrl }
