Example code for implementing verification code login in SMS API in Node

const Core = require('@alicloud/pop-core'); //cwen calls Ali SMS module (need to be installed first)
//cwen configures the Alibaba SMS service API let client = new Core({
 accessKeyId: '<accessKeyId>', // Need to apply first (steps below)
 accessKeySecret: '<accessSecret>', // Need to apply first (steps below)
 endpoint: 'https://dysmsapi.aliyuncs.com', //No need to change apiVersion: '2017-05-25' //No need to change });
//cwen request method let requestOption = {
  method: 'POST'
};

//# Generate a random four-digit number to simulate the verification code function rander(max, min) {
  return Math.floor(Math.random() * (max - min)) + min
}
//# Store mobile phone number + verification code (for easy verification)
var loginInfo = [];
//# Verify whether the phone number has sent a verification code let validate = (phone) => {
  return loginInfo.some(item => item.phone === phone)
}
//# Verify that the verification code is consistent let validateCode = (phone, code) => {
  return loginInfo.some(item => (item.phone === phone && item.code == code))
}

//cwen uses Alibaba Cloud API to send SMS verification (verification code login)
