原理：我们自己生成随机数验证码，存入缓存中，并给手机发送验证码，登录时，获取输入的验证码与缓存中的验证码比对是否一致。


    /**
     * 获取验证码
     */
    public function captcha()
    {
        (new TelValidate())->goCheck('captcha');//验证规则
        $code = (new Captcha(input('param.tel')))->sendCaptcha();
        $this->result(1, '验证码已发送' . $code);
    }

         * 下发验证码
         * @return int 验证码
         */
    public function sendCaptcha()
    {
        $this->checkCodeNum();
        $code = rand(111111, 999999);//生成验证码
        $value_info = SystemSetModel::getValueByName('sms_body', 'config_value');
        $body = str_replace(
            '{generate_code}',
            $code,
            $value_info->config_value
        );
        
            $res = appSendSMS($this->mobile, $body);
            $res = json_decode($res, true);
            if (!isset($res['State']) && $res['State'] != 0) {
                self::json(0,'验证码发送失败');
            }
        $this->mobileCode($code);
        $this->setCodeNum();
        return $code;
    }


    /**
     * 存储/验证 验证码
     * @param int $code 验证码
     * @param int $type 1、存储，2、验证
     * @return bool
     */
    public function mobileCode($code, $type = 1)
    {
        if ($type == 1) {
            Cache::set($this->mobile, $code, 900);
            return true;
        } else {

            }
            if ($code == $logCode) {
                Cache::rm($this->mobile);
                return true;
            } else {
                self::json(0,'验证码错误');
            }
        }
    }

   /**
     * 更新获取验证码次数与时间
     */
    private function setCodeNum() {
        //计算现在到明天凌晨的时间
        $tomorrow = strtotime(date('Y-m-d', strtotime('+1 day')));
        $ttl = $tomorrow - time();
        $logMobile = Cache::get('logMobile');
        $logMobile[$this->mobile]['num'] -= 1;
        $logMobile[$this->mobile]['time'] = time();
        Cache::set('logMobile', $logMobile, $ttl);
