【OSS】Bucket读写权限

用户创建的Bucket总共有三种权限：

/*私有 * 只允许自己读写操作，其他用户没有权限 */CannedAccessControlList acl_private = CannedAccessControlList.Private;/*公共读写 * 允许自己和其他用户读写操作 */CannedAccessControlList acl_pub_readwrite = CannedAccessControlList.PublicReadWrite;/*公共读 * 只允许自己进行写操作，但是允许自己及其他用户进行读操作 */CannedAccessControlList acl_pub_red = CannedAccessControlList.PublicRead;
