最近使用到手机短信校验，分享一下我的实现方式，也希望能够了解更好的实现方式 使用短信平台：阿里大鱼（阿里巴巴） 使用语言：node.js 数据库：redis（可用任意数据库或文件操作替代） 实现代码如下：

//安装依赖
//redis 数据库操作模块
npm install redis
//taobao API 操作模块。ES6请使用topapi-node
npm install top

//AuthController
var redisClient = require('../bin/redisClient');
var regx = /^(13|15|17|18|14)[0-9]{9}$/;
var top = require("top");
var client = top.createClient({
  appkey:'******',
  appsecret:'*******',
  REST_URL: 'http://gw.api.taobao.com/router/rest'
});
var params_check = {
      extend:"",
      sms_type:"normal",
      sms_free_sign_name:"注册验证",
      sms_param:'{"product":"网站名","code":"'+parseInt(code)+'"}',
      rec_num:tel,
      sms_template_code:"SMS_1020033"
    };

module.exports = {
  /**
   * 发送短信验证
   * @param req
   * @param res
   */
    "smsCheck":function(req,res){
    var tel = req.query.tel;
    if (!tel || !regx.exec(tel))return res.json({errMsg: "tel is no true", errCode: "400"});
    //生成4位数字的随机数
    var code = Math.floor(Math.random() * (9999 - 999 + 1) + 999);
    //检查用户是否已经注册
    User.findOne({tel: tel}).exec(function findOneCB(err, user) {
      if (user) return res.json({errMsg: "该手机号已被注册", errCode: "400"});
      redisClient.exists("register:" + tel, function (err, result) {
        if (err)return res.json({errMsg: "服务器出错，请重试", errCode: "500"});
        if (result == 1)return res.json({errMsg: "请求过于频繁，请稍候重试", errCode: "423"});
        //发送短信
        client.invoke('alibaba.aliqin.fc.sms.num.send', params_check, [], null, 'GET', function (err, result) {
          if (!err) {
            //发送成功
            redisClient.multi()
              //限制访问频率60秒
              .set("register:" + tel, code)
              .expire("register:" + tel, 60)
              .hset("code:" + tel, "code",code)
              .hset("code:" + tel,"count",0)
              .exec(function (err, replies) {
                if (!err)return res.json({errMsg: "ok", errCode: 0});
              });
          } else {
            res.json({errMsg: "服务器出错，请重试", errCode: "500"});
          }
        });
      });
    });
