计数器获取，参数appId ，返回数量，redis 保存 过期时间14天 log:counter
每调用一次随机增加 1～5

public function actionFetchCounter() { try { $params = $_GET ?: $_POST; if (empty($params['appId'])) { $this->jsonReturnError(Constants::CODE_FAILED, '缺少参数appId'); } $key = 'logcenter:counter:' . $params['appId']; $rand = mt_rand(1, 5); $redis = RedisClient::getInstance();//使用默认的redis $redis->expire($key, 14 * 86400);//设置14天的过期时间 $redis->incrBy($key, $rand); $counter = $redis->get($key); $this->jsonReturnSuccess(Constants::CODE_SUCCESS, ['counter' => $counter], '成功'); } catch (\Exception $e) { $this->jsonReturnError(Constants::CODE_FAILED, '异常错误'); } }
