获取bucket下的object列表
| public listObjects ( string $bucket, array $options = NULL ) : OSS\Model\ObjectListInfo | ||
| $bucket | string | |
| $options | array | 其中options中的参数如下 $options = array( 'max-keys' => max-keys用于限定此次返回object的最大数，如果不设定，默认为100，max-keys取值不能大于1000。 'prefix' => 限定返回的object key必须以prefix作为前缀。注意使用prefix查询时，返回的key中仍会包含prefix。 'delimiter' => 是一个用于对Object名字进行分组的字符。所有名字包含指定的前缀且第一次出现delimiter字符之间的object作为一组元素 'marker' => 用户设定结果从marker之后按字母排序的第一个开始返回。 ) 其中 prefix，marker用来实现分页显示效果，参数的长度必须小于256字节。 |
