php实现的IMEI限制的短信验证码发送类

isMobile($mobile)) {      $this->error = array(''code'' => -1, ''msg'' => ''这个手机号很奇葩哦，请正确输入后重试'');      return false;    }     $redis = Api_Common::redis();    $vcKey = ''VC_''.$mobile;    $limitKey = ''VC_LIMIT_''.$mobile;     // 验证码重发限制    $data = json_decode($redis->get($vcKey), true);    if($data && time() < $data[''resend_expire'']) {      $this->error = array(''code'' => -1, ''msg'' => ''短信已在1分钟内发出，请耐心等待'');      return false;    }     // 手机号及IMEI限制    $sendCnt = $redis->zScore($limitKey, $imei);    if($sendCnt && $sendCnt >= self::ONE_DAY_FREQ) {      $this->error = array(''code'' => -1, ''msg'' => ''没收到短信?请稍等或检查短信是否被屏蔽'');      return false;    }    $imeiCnt = $redis->zCard($limitKey);    if($imeiCnt >= self::ONE_DAY_IMEI_COUNT && !$sendCnt) {      $this->error = array(''code'' => -1, ''msg'' => ''已超过验证码发送设备限制'');      return false;    }     // 获取验证码    if(!$data) {      $vc = strval(rand(100000, 999999));      $data = array(''vc'' => $vc, ''resend_expire'' => 0);      $redis->set($vcKey, json_encode($data));      $redis->expire($vcKey, self::EXPIRE_SEC); // 设置验证码过期时间    }    $vc = $data[''vc''];     $content = ''安全验证码：''.$vc;    $result = $this->send($mobile, $content);    if($result) {      // 重设重发时限      $data[''resend_expire''] = time() + self::RESEND_SEC;      $ttl = $redis->ttl($vcKey);      $redis->set($vcKey, json_encode($data));      $redis->expire($vcKey, $ttl);       // 设置手机号与IMEI限制      $redis->zIncrBy($limitKey, 1, $imei);      $redis->expireAt($limitKey, strtotime(date(''Y-m-d'',strtotime(''+1 day''))));    }    return $result;  }   /**   * 向指定手机号发送短信   * @param $mobile   * @param $content   * @return bool   */  public function send($mobile, $content){    // TODO 调用具体服务商API    return true;  }   /**   * 判断是否为合法手机号   * @param $mobile   * @return bool   */  private function isMobile($mobile) {    if(preg_match(''/^1\d{10}$/'', $mobile))      return true;    return false;  }   /**   * 验证短信验证码   * @param $mobile   * @param $vc   * @return bool   */  public function checkVerifyCode($mobile, $vc) {    $vcKey = ''VC_''.$mobile;    $vcData = json_decode(Api_Common::redis()->get($vcKey), true);    if($vcData && $vcData[''vc''] === $vc) {      return true;    }    return false;  }   /**   * 清除验证码   * @param $mobile   */  public function cleanVerifyCode($mobile) {    $redis = Api_Common::redis();    $vcKey = ''VC_''.$mobile;    $limitKey = ''VC_LIMIT_''.$mobile;    $redis->del($vcKey);    $redis->del($limitKey);  }}
