Question

描述

该操作用于列出Bucket下的Objects。
单次操作最多可列出1000个Objects。如果需要列出Bucket下的所有Objects，则需要循环执行该操作。
可以通过prefix参数只将Bucket下包含特定前缀的objects列出。 Delimiter参数可以用于将相同prefix的objects聚合在一起。例如，Bucket下有2016/05.log和2016/06.log，如果指定delimiter为'/'，则只返回2016这个公共前缀。

Note

• 如果需要列出用户的所有Buckets，请参考List Buckets。

Note

如果prefix和delimiter都非空，则prefix必须以delimiter结尾。
