转眼又要过了一年了 好久没写博客了，人不学就要落后，今天有时间把以前弄的发送阿里云短信验证码登录记录一下。

1）去阿里云官网注册一个账号。有账号直接登录就行，以前新人好像有免费的短信可以学习 ，现在我们只能购买了 先开通短信服务然后去购买 购买链接

2）跳转到控制台的短信服务点击国内消息签名模板 右边点添加签名。后面在模板管理哪里添加模板  。

模板这个签名的意思就是 发送短信验证码的头部，类似于发票的抬头文字  一般个人只能申请一个验证码签名。企业的不知道（没试过。。。）。模板就是具体的内容，里面可以使登录的验证码  注册的验证码 找回密码的验证码   加上签名就是 【xxx时光管】 您好，你登录的验证码是520886。【】不用写在签名里面 发短信的时候会自动加上。个人的签名不能包含一些企业的文字  到时候他会告诉你签名、模板注意事项。

3）查看个人的accessKeyId跟accessSecret 右上角点个人头像点击AccessKey管理。没有的就创建一个，有的话就看列表点击查看Secret  然后验证一下就可以了，记住这两个key

1）写一个发送验证码的辅助类SMS

public class SMS
{
///

/// 发送短信 ///

/// 手机号码
/// 验证码
/// 验证码模板
/// accessKeyId= LTAIA8bLXzkMsKR4JB8
/// secret= SamAiMzbdC0yS1lo6u9O9r
/// 签名名称
///
public static SendMessageDto SendSMS(string phone, string code, string templateName, string accessKeyId, string secret, string signName)
{
var ret = new SendMessageDto();
IClientProfile profile = DefaultProfile.GetProfile("cn-hangzhou", accessKeyId, secret);
DefaultAcsClient client = new DefaultAcsClient(profile);
CommonRequest request = new CommonRequest
{
Method = MethodType.POST,
Domain = "dysmsapi.aliyuncs.com",
Version = "2017-05-25",
Action = "SendSms"
};
request.AddQueryParameters("PhoneNumbers", phone);
request.AddQueryParameters("SignName", signName);
request.AddQueryParameters("TemplateCode", templateName);
request.AddQueryParameters("TemplateParam", $"{{'code':'{code}'}}");
// request.Protocol = ProtocolType.HTTP;

        try  
        {  
            CommonResponse response = client.GetCommonResponse(request);  
            var result = Encoding.Default.GetString(response.HttpResponse.Content);  
            var resultJson = JsonConvert.DeserializeObject<SendMessageDto>(result);  
            ret = resultJson;  
        }  
        catch (ServerException e)  
        {  
            Console.WriteLine(e);  
        }  
        catch (ClientException e)  
        {  
            Console.WriteLine(e);  
        }  
        return ret;  
    }  
}  
public class SendMessageDto  
{  
    /// <summary>  
    /// 状态码的描述。  
    /// </summary>  
    public string Message { get; set; }  
    /// <summary>  
    ///    请求ID。  
    /// </summary>  
    public string RequestId { get; set; }  
    /// <summary>  
    ///  发送回执ID，可根据该ID在接口QuerySendDetails中查询具体的发送状态。  
    /// </summary>  
    public string BizId { get; set; }  
    /// <summary>  
    /// 请求状态码。 返回OK代表请求成功。  
    /// </summary>  
    public string Code { get; set; }  
}

2）验证码配置类SMSConfig

///

/// 验证码配置类 ///

public class SMSConfig
{
public string AccessKeyId { get; set; }
public string AccessSecret { get; set; }
public string SignName { get; set; }
public Login Login { get; set; }
public Regist Regist { get; set; }
public Reset Reset { get; set; }
}
///

/// 验证码模板 ///

public class Login
{
///

/// 类型 1登录 2注册 3找回、重置密码 ///

//public int Type { get; set; }
///

/// 模板名称 ///

public string TemplateName { get; set; }
}
public class Regist
{

    /// <summary>  
    /// 模板名称  
    /// </summary>  
    public string TemplateName { get; set; }  
}  
public class Reset  
{

    /// <summary>  
    /// 模板名称  
    /// </summary>  
    public string TemplateName { get; set; }  
}

3）数据库建立一张表存储验证码

public partial class SysSendSms
{
///

/// Id ///

[Key]
[Column("Id", Order = 0)]
[Required()]
[Display(Name = "Id")]
public int Id { get; set; }
///

/// 验证码 ///

[Column("Code")]
[StringLength(20, ErrorMessage = "{0}长度不能超过20个字符")]
[Display(Name = "验证码")]
public string Code { get; set; }
///

/// 手机号 ///

[Column("Phone")]
[StringLength(20, ErrorMessage = "{0}长度不能超过20个字符")]
[Display(Name = "手机号")]
public string Phone { get; set; }
///

/// 发送时间 ///

[Column("SendTime")]
[Display(Name = "发送时间")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:yyyy-MM-dd HH:mm:ss:ffff}")]
public DateTime? SendTime { get; set; } = DateTime.Now;
///

/// gid ///

[Column("Guid")]
[StringLength(36, ErrorMessage = "{0}长度不能超过36个字符")]
[Display(Name = "Guid")]
public string Guid { get; set; }
///

/// 次数 ///

[Column("Count")]
[Display(Name = "次数")]
public int? Count { get; set; }
///

/// 是否用了 ///

[Column("IsUsed")]
[Display(Name = "领取数量")]
public bool? IsUsed { get; set; }
///

/// 类型1登陆 2注册 ///

[Column("Type")]
[Display(Name = "类型1登陆 2注册")]
public int? Type { get; set; }
}

这个type可以自己定义，我这边演示一个登陆的发送验证码

4）发送短信方法

public async Task SendSMSAsync(SendSmsDto sendSmsDto)
{
var code = new Random().Next(1000, 9999).ToString();
var templateName = sendSmsDto.Type switch
{
1 => _smsConfig.Value.Login.TemplateName,
2 => _smsConfig.Value.Regist.TemplateName,
_ => _smsConfig.Value.Login.TemplateName
};
return await Send(sendSmsDto.Phone, sendSmsDto.Type, code, templateName);
}

///

/// 发送短信验证码 ///

/// 手机
/// 类型（后面数据库好区分，防止乱发）
/// 验证码
/// 模板申请下来对应的Code
///
private async Task Send(string phone, int type, string code, string templateName)
{
//手机号相同 密码相同 没有用过的
var model = _db.SysSendSms.OrderByDescending(x=>x.SendTime).FirstOrDefault(x => x.Phone == phone && x.Type == type && x.IsUsed == false);
var guid = Guid.NewGuid().ToString("N");
var dt = DateTime.Now;//时间
if (type == 1)//登录
{
var ckuser = _db.Customer.Any(x => x.Phone == phone);
if(!ckuser)
{
var cus = new Customer
{
Phone = phone,
LoginID = phone,
Gid = Guid.NewGuid().ToString("N"),
Pwd = SecurityHelper.MD5(phone)
};
_db.Customer.Add(cus);
_db.SaveChanges();
return await CkSend(phone, type, code, templateName, model, guid, dt);
}
else
return await CkSend(phone, type, code, templateName, model, guid, dt);
}
else
return Result.ToFail("请求参数错误，type");
}

检查发送验证码的方法 为了防止恶意乱发

///

/// 看看以前发过没有 ///

///
///
///
///
///
///
///
///
private async Task CkSend(string phone, int type, string code, string templateName, SysSendSms model, string guid, DateTime dt)
{
if (model == null)//没有发送过
{
var sendMess = SMS.SendSMS(phone, code, templateName, _smsConfig.Value.AccessKeyId, _smsConfig.Value.AccessSecret, _smsConfig.Value.SignName);
if (sendMess.Code == "OK")
{
await SaveData(phone, type, code, guid, dt);
return Result.ToSuccess(new { code });
}
else
return Result.ToFail("短信验证码发送失败" + sendMess.Code + sendMess.Message);
}
else
{
var co = model.Count;//发送次数
if (co >= 5 && dt.AddHours(-5) < model.SendTime)//大于3次并且时间在3个小时内 return Result.ToFail("短信验证码发送频繁，请3个小时再试"); else /*(co >= 8 && dt.AddDays(-1) < model.SendTime)//大于8次并且时间在24个小时内*/
{
var sendMess = SMS.SendSMS(phone, code, templateName, _smsConfig.Value.AccessKeyId, _smsConfig.Value.AccessSecret, _smsConfig.Value.SignName);
if (sendMess.Code == "OK")
{
model.Count++;
model.SendTime = DateTime.Now;
model.Code = code;
_db.SaveChanges();
return Result.ToSuccess(new { code });
}
else
return Result.ToFail("短信验证码发送失败"+ sendMess.Code+sendMess.Message);
}
}
}

    /// <summary>  
    /// 保存发送信息到数据库  
    /// </summary>  
    /// <param name="phone"></param>  
    /// <param name="type"></param>  
    /// <param name="code"></param>  
    /// <param name="guid"></param>  
    /// <param name="dt"></param>  
    /// <returns></returns>

    private async Task SaveData(string phone, int type, string code, string guid, DateTime dt)  
    {  
        var modelSMS = new SysSendSms  
        {  
            Code = code,  
            Phone = phone,  
            SendTime = dt,  
            Guid = guid,  
            Count = 1,  
            IsUsed = false,  
            Type = type  
        };  
        \_db.SysSendSms.Add(modelSMS);  
        await \_db.SaveChangesAsync();  
    }

我这边的逻辑其实是写死的  type只能是1  就是这个用户不在数据库里面先创建用户 然后发送验证码。在里面就直接发送验证码。下面是登录方法

public async Task LoginAsync(LoginDto loginDto)
{
try
{
var model = _db.Customer.FirstOrDefault(x => x.LoginID == loginDto.Phone);
if (model != null)
{
var send = _db.SysSendSms.OrderByDescending(x => x.SendTime).FirstOrDefault(x => x.Code == loginDto.Code);
if (send == null)
return Result.ToFail("手机验证码错误");
else
{
Dictionary keyValues = new Dictionary()
{
{"Id",model.LoginID }
};
var token = _tokenHelper.CreateToken(keyValues);
send.IsUsed = true;
model.Token = token.TokenStr;
await _db.SaveChangesAsync();
return Result.ToSuccess(token);
}
}
else
return Result.ToFail("用户不存在");
}
catch (Exception ex)
{
return Result.ToError(ex);
}
}

public class LoginDto
{
///

/// 手机号码 ///

public string Phone { get; set; }
///

/// 验证码 ///

public string Code { get; set; }
}

如果验证成功了就要把数据库发送短信验证码的字段IsUse改成true

我的模板 签名都写在配置文件里面

//短信验证码配置 所有配置来自阿里云官方
"SMSConfig": {
"AccessKeyId": "LTAI4GB1mA8bLXzkMsKR4JB8",
"AccessSecret": "SamAiMzbZ4ufoNRndC0yS1lo6u9O9r",
"SignName": "真猴吃", //签名名称
"Login": {
"TemplateName": "SMS_200700770" //登录模板代码
},
"Regist": {
"TemplateName": "SMS_180347559" //注册模板代码
},
"Reset": {
"TemplateName": "SMS_192835767" //找回密码模板代码
}
},

这与上面的接收类一样的格式  当然在Core里面别忘了配置连接字符串  再调用的类或者接口在startup里面注册

services.Configure(Configuration.GetSection("SMSConfig"));
