我使用workerman Thrift Rpc框架，在Handler文件中實(shí)現(xiàn)接口方法的時(shí)候，想連mysql查詢一下數(shù)據(jù)的時(shí)候報(bào)下面錯(cuò)，如果不連接mysql就沒有問題，不知道為什么

PHP Fatal error:  Uncaught exception 'Thrift\Exception\TTransportException' with message 'TSocket read 0 bytes' in \workerman-thrift-master\Applications\ThriftRpc\Lib\Thrift\Transport\TSocket.php:269

代碼就是很簡(jiǎn)單的一句連一下mysql
$mysqli = new mysqli($dbhost,$dbuser,$dbpass,$dbname);
