请问个人小程序云函数能否打开https普通链接（已有node_modules）？需要SSL之类的设置吗？

const cloud = require('wx-server-sdk')

var rp = require('request-promise');

cloud.init()

exports.main = async (event, context) => {

  let url = 'https://www.baidu.com';

  return await rp(url)

    .then(function (res) {

      return res

    })

    .catch(function (err) {

      return '失败'

    });

}

运行出错：

fail Error: cloud.callFunction:fail -404011 cloud function execution error. 云函数执行错误
