猜测是因为用了服务没用sid的原因，没找到解决办法，所以修改代码

PDOException in Connection.php line 295
SQLSTATE[HY000]: pdo_oci_handle_factory: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

composer引入的oracle包里

vendor\topthink\think-oracle\src\Connection.php

protected function parseDsn($config)
{
	$dsn = 'oci:dbname=';
	if (!empty($config['hostname'])) {
		//  Oracle Instant Client
		$dsn .= '//' . $config['hostname'] . ($config['hostport'] ? ':' . $config['hostport'] : '') . '/';
	}
	$dsn .= $config['database'];
	if (!empty($config['charset'])) {
		$dsn .= ';charset=' . $config['charset'];
	}
	return $dsn;
}

修改为

   protected function parseDsn($config)
    {

        $dsn = 'oci:dbname=';
        if (!empty($config['hostname'])) {
            //  Oracle Instant Client
			$dsn.='(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = '.$config['hostname'].')(PORT = '.$config['hostport'].'))
    (CONNECT_DATA =

      (SID  = '.$config['database'].')
    )
  )';
        }
        if (!empty($config['charset'])) {
            $dsn .= ';charset=' . $config['charset'];
        }
        return $dsn;
    }

完美连接
