.NET MVC 短信验证码过程

1:创建一个项目用来调用第三方的类,右键Nuget添加第三方的引用类库 qcloudsms_csharp

2:把第三方的公共类放入到我们的项目里

using qcloudsms;
using qcloudsms_csharp.httpclient;
using qcloudsms_csharp.json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace MiShop.Remote
{
    public class TenXunYunSMS
    {
        //appId
        public int appId;
        //appKey
        public string appKey = "";
        //短信模板ID
        private int tmplateId = 379257;
        //签名内容
        private string smsSign = "7hhhcn";
        /// <summary>
        /// 验证码
        /// </summary>
        public int Code { get; set; }
        /// <summary>
        /// 发送验证码
        /// </summary>
        /// <param name="phone"></param>
        /// <returns></returns>
        public void SetSMS(string phone)
        {
            Random random = new Random();
            int code = random.Next(100000, 999999);
            try
            {
                SmsSingleSender ssender = new SmsSingleSender(appId, appKey);
                var result = ssender.sendWithParam("86", phone,
                tmplateId, new[] { code.ToString() }, smsSign, "", "");  // 签名参数未提供或者为空时，会使用默认签名发送短信
            }
            catch (JSONException ex)
            {
                throw;
            }
            catch (HTTPException ex)
            {
                throw;
            }
            catch (Exception ex)
            {
                throw;
            }
            Code = code;
        }
    }
}

3:创建一张短信发送记录表 

//信息记录表
public class SMSInfo
    {
            public int Id { get; set; }
            public int Code { get; set; }
            public Int64 TelPhone { get; set; }
            //创建时间
            public DateTime CreateTime { get; set; }
            //短信过期时间
            public DateTime ExpireTime { get; set; }
    }

4:数据访问层写插入短信信息表方法

public class SMSInfoRepository
    {   
        /// <summary>
        /// 将验证码和电话保存至数据库
        /// </summary>
        /// <param name="sMSInfo"></param>
        /// <returns></returns>
        public int InsertSMSInfo(SMSInfo sMSInfo)
        {
            int result = -1;
            string sql = @"insert into SMSInfo values(@Code, @TelPhone, @CreateTime, @ExpireTime)";
            SqlParameter[] sqlParameter = {
                new SqlParameter(){
                    DbType=DbType.Int32,
                    ParameterName="@Code",
                    Value=sMSInfo.Code
                },
                 new SqlParameter(){
                    DbType=DbType.Int64,
                    ParameterName="@TelPhone",
                    Value=sMSInfo.TelPhone
                },
                  new SqlParameter(){
                    DbType=DbType.DateTime,
                    ParameterName="@CreateTime",
                    Value=DateTime.Now
                },
                   new SqlParameter(){
                    DbType=DbType.DateTime,
                    ParameterName="@ExpireTime",
                    Value=DateTime.Now.AddMinutes(5)
                }
            };
            DBHelper dBHelper = new DBHelper();
            result =dBHelper.ExcuteNoQuery(sql,sqlParameter);
            return result;
        }
        /// <summary>
        /// 查询电话和验证码是否正确
        /// </summary>
        /// <param name="sMSInfo"></param>
        /// <returns></returns>
        public int SelCodePhone(SMSInfo sMSInfo)
        {
            int result = -1;
            string sql = @"select COUNT(1) from SMSInfo where [email protected] and [email protected] and ExpireTime>@ExpireTime";
            SqlParameter[] sqlParameter = {
                new SqlParameter(){
                    DbType=DbType.Int32,
                    ParameterName="@Code",
                    Value=sMSInfo.Code
                },
                 new SqlParameter(){
                    DbType=DbType.Int64,
                    ParameterName="@TelPhone",
                    Value=sMSInfo.TelPhone
                },
                    new SqlParameter(){
                    DbType=DbType.DateTime,
                    ParameterName="@ExpireTime",
                    Value=DateTime.Now
                }
            };
            DBHelper dBHelper = new DBHelper();
            result = dBHelper.ExecuteScalar(sql, sqlParameter);
            return result;
        }
    }

5:业务层:先引用第三方项目,先调用第三方类，发送验证码,然后将验证码存储到短信信息对象，最后调用数据访问层的插入短信的方法。

 public class SMSInfoSerivice
    {
        /// <summary>
        /// 获取验证码同时将验证码保存至数据库
        /// </summary>
        /// <param name="phone"></param>
        /// <returns></returns>
        public bool GetCode(string phone)
        {
            //调用第三方类
            TenXunYunSMS tenXunYunSMS;
            try
            {
                tenXunYunSMS = new TenXunYunSMS();
                tenXunYunSMS.appId = Convert.ToInt32(ConfigurationManager.AppSettings["appId"]);
                tenXunYunSMS.appKey = ConfigurationManager.AppSettings["appKey"];
                tenXunYunSMS.SetSMS(phone);
            }
            catch (Exception)
            {

                return false;
            }
            SMSInfoRepository sMSInfoRepository = new SMSInfoRepository();
            //创建信息对象保存验证码和电话号码
            SMSInfo sMSInfo = new SMSInfo();
            //将验证码存储到短信信息对象
            sMSInfo.Code = tenXunYunSMS.Code;
            sMSInfo.TelPhone = Convert.ToInt64(phone);
            //调用插入短信信息的方法 成功返回true
            return sMSInfoRepository.InsertSMSInfo(sMSInfo)>0;
        }
        /// <summary>
        /// 查询电话和验证码是否正确
        /// </summary>
        /// <param name="sMSInfo"></param>
        /// <returns></returns>
        public bool SelCodePhone(SMSInfo sMSInfo)
        {
            SMSInfoRepository sMSInfoRepository = new SMSInfoRepository();
            return sMSInfoRepository.SelCodePhone(sMSInfo)>0;
        }
    }

6:控制器写一个JsonResult的发送验证码方法需要接收手机号 

public JsonResult GetCode(string phone)
        {
            Operate operate = new Operate();
            SMSInfoSerivice sMSInfoSerivice = new SMSInfoSerivice();
            operate.Success = sMSInfoSerivice.GetCode(phone);
            return Json(operate);
        }

7:控制器写一个JsonResult的校验验证码方法需要接收短信信息对象 

//点击注册时查询电话号码与短信验证码是否存在
public JsonResult SelCodePhone(SMSInfo sMSInfo)
        {
            Operate operate = new Operate();
            SMSInfoSerivice sMSInfoSerivice = new SMSInfoSerivice();
            operate.Success = sMSInfoSerivice.SelCodePhone(sMSInfo);
            return Json(operate);
        }

8:页面点击获取验证码按钮：先禁用按钮，然后ajax post提交到控制器对应的发送验证码方法，传入手机号，然后success处理返回的结果。

     //点击获取验证
        $("#GetCode").click(function () {
            var tel = $("#tel").val();
            $.ajax({
                url: "/SMSCode/GetCode?phone=" + tel,
                type: "post",
                success: function (result) {
                    if (result.Success) {
                        alert("获取成功");
                        //调用短信验证计时器方法
                        IntervalSMS();
                    }
                    else {
                        alert("获取失败");
                    }
                }
            })
        })

//短信验证计时器
    function IntervalSMS() {

        $("#GetCode").attr("disable", "disabled");
        $("#GetCode").css("color", "red");

        var time = 30;
        $("#GetCode").val(time + " S后重新获取验证码");

        var timer = setInterval(function () {
            if (time > 0) {
                time--;
                $("#GetCode").val(time + " S后重新获取验证码");
            }
            else {
                $("#GetCode").removeAttr("disable").css("color", "black");
                $("#GetCode").val("重新获取验证码");
                clearInterval(timer);
            }
        }, 1000)
    }

9:点击注册按钮，写一个校验验证码的方法,校验通过之后才能注册。 

    //注册按钮  查询记录  为true进行保存注册
        $("#btnRe").click(function () {

            if (ckname == true && ckphone == true && ckrepwd == true && ckpwd == true) {

                var SMSInfo = {};
                SMSInfo.TelPhone = $("#tel").val();
                SMSInfo.Code = $("#yan").val();
                $.ajax({
                    url: "/SMSCode/SelCodePhone",
                    type: "post",
                    data: SMSInfo,
                    success: function (result) {
                        if (result.Success) {
                    //点击注册时查询电话和验证码是否正确 正确则调用该方法进行注册
                            reg();
                        }
                        else {
                            alert("短信验证码不存在");
                            return;
                        }
                    }
                })
            }
            else {
                alert("信息验证未通过无法注册成功");
            }


//点击注册时查询电话和验证码是否正确 正确则调用该方法进行注册
    function reg() {
        var userInfo = {};
        userInfo.UserName = $("#username").val();
        userInfo.UserPwd = $("#password").val();
        userInfo.UserPhone = $("#tel").val();
        $.ajax({
            url: "/Register/SaveUserInfo",
            data: userInfo,
            type: "post",
            success: function (result) {
                if (result.Success) {
                    alert("注册成功");
                }
                else {
                    alert("注册失败");
                }
            }
        })
    }
