$regionmap = array('cn-east'=>'ap-shanghai',
'cn-sorth'=>'ap-guangzhou',
'cn-north'=>'ap-beijing-1',
'cn-south-2'=>'ap-guangzhou-2',
'cn-southwest'=>'ap-chengdu',
'sg'=>'ap-singapore',
'tj'=>'ap-beijing-1',
'bj'=>'ap-beijing',
'sh'=>'ap-shanghai',
'gz'=>'ap-guangzhou',
'cd'=>'ap-chengdu',
'sgp'=>'ap-singapore',);

region使用前面的比如bj 既可以解决问题了！
