第一步，调用阿里云Api发送短信并存入数据库或者是redis当中

• 阿里云短信平台网址
  [https://api.aliyun.com/new#/?product=Dysmsapi&version=2017-05-25&api=SendSms&params={"RegionId":"cn-hangzhou","TemplateCode":"345","PhoneNumbers":"17633802772"}&tab=DEMO&lang=GO]

• 使用json配置文件

  1.  // 配置文件
      "sms": {
          "sign_name": "虚拟云餐厅",
          "template_code": "SMS_205471746",
          "app_key": "",
          "app_secret": "",
          "region_id": "cn-hangzhou"
      }
     

  2. 配置文件解析

  func ParseConfig(path string) (*Config, error) {
  
  file, err := os.Open(path)
  if err != nil {
  	panic(err)
  }
  defer file.Close()
  newReader := bufio.NewReader(file)
  decoder := json.NewDecoder(newReader)
  err = decoder.Decode(&config)
  if err != nil {
  	panic(err)
  }
  return config, nil
  }
  

• 编写路由controller层

•  //发送手机验证码
   engine.GET("/api/sendcode",mc.SendSmsCode )
   //手机号和短信登录
   engine.POST("/api/login_sms", mc.smsLogin)
   //删除验证码
  

• 发送短信

func (mc *MemBerController) SendSmsCode(context *gin.Context) {
	phone, err := context.GetQuery("phone")
	if !err {
		context.JSON(200, map[string]interface{}{
			"code":    0,
			"message": "手机号不存在",
		})
		return
	}
	ms:=Service.MemberService{}
	isSend := ms.Sendcode(phone)//调用service层方法发送验证码
	if  isSend {
		context.JSON(200, map[string]interface{}{
			"code":1,
			"msg":"发送成功",
		})

	}else {
		context.JSON(200, map[string]interface{}{
			"code": 0,
			"msg":  "发送失败",
		})
	}

}

• service层

func (msi * MemberService)Sendcode(phone string) bool  {
	//随机产生一个验证码
	code := fmt.Sprintf("%06v", rand.New(rand.NewSource(time.Now().UnixNano())).Int31n(1000000))
	smsConfig := config.GetConfig().Sms
	//调用阿里云短信接口发送短信
    //client, err := dysmsapi.NewClientWithAccessKey("cn-hangzhou", "<accessKeyId>", "<accessSecret>")
    client, err := dysmsapi.NewClientWithAccessKey(smsConfig.RegionId, smsConfig.AppKey, smsConfig.AppSecret)

	if err != nil {
		panic(err)
	}

	request := dysmsapi.CreateSendSmsRequest()
	//request属性设置
	request.Scheme = "https"

	request.SignName = smsConfig.SignName
	request.TemplateCode = smsConfig.TemplateCode
    request.PhoneNumbers = phone

    //使用json字符串发送验证码
	par, err := json.Marshal(map[string]interface{}{
		"code": code,
	})

	//设置验证码
	request.TemplateParam = string(par)

	response, err := client.SendSms(request)

	fmt.Println( response)
	if err != nil {
		err.Error()
		return false
	}
	//检查返回结果，并判断发生状态
	if response.Code != "OK" {
        smsCode := model.SmsCode{Phone: phone, Code: code, BizId: response.BizId, CreateTime: time.Now().Unix()}
        //插入数据库操作
		memberDao := dao.MemberDao{util.DdEngie}
		insertCode := memberDao.InsertCode(smsCode)
		return insertCode>0

		return true
	}
	return true
}

• Dao层
  • 数据库表结构

  //验证码表结构
  type SmsCode struct {
      Id         int64 `xorm:"pk autoincr"  json:"id"`
      Phone      string `xorm:"varchar(11)" json:"phone"`
      BizId      string `xorm:"varchar(30)" json:"biz_id"`
      Code       string `xorm:"varchar(4)"  json:"code"`

  }
  //用户表结构
  //用户类

}

验证码登录

• 路由

engine.POST("/api/login_sms", mc.smsLogin)

//短信登录
func (mc *MemBerController) smsLogin(context *gin.Context) {

    var smsParam param.SmsLoginParam
    //解析请求参数
    // type SmsLoginParam struct {
	// Phone string `json:"phone"`

    // }
	err := util.Decode(context.Request.Body, &smsParam)
	if err != nil {
		util.Failed(context, "参数解析错误")
		return
	}
//完成手机加短信的登录方法
	us := Service.MemberService{}
	member := us.SmsLogin(smsParam)
	if member != nil {
		util.Success(context, member)
		return
	}
	util.Failed(context, "登录失败")
}

func (msi *MemberService) SmsLogin(param param.SmsLoginParam) *model.Member {

    dao := dao.MemberDao{}
    //查询封装的验证码表结构
	sms := dao.ValidateSmsCode(param.Phone, param.Code)
