ListObjects 命令是否保证结果按关键字排序? [英] Does the ListObjects command guarantee the results are sorted by key?

问题描述

在调用 S3 ListObjects 命令(通过 REST 或 SOAP API)时，结果集是否以任何特定顺序返回?鉴于对象键和标记的性质，我希望结果集始终按对象键排序.但我没有看到任何文件证实这一点.

When calling the S3 ListObjects command (via either REST or SOAP API), is the result set returned in any particular order? I would expect, given the nature of object keys and markers, that the result set is always sorted by object key. But I haven't seen any documentation confirming this.

更新:亚马逊已更改其文档，如下所示.

Update: Amazon has changed their documentation as shown below.

它们按字母顺序返回.列表结果始终以 UTF-8 二进制顺序返回.请参阅 http://docs.aws.amazon.com/AmazonS3/latest/dev/ListingKeysUsingAPIs.html

They are returned alphabetically. List results are always returned in UTF-8 binary order. See http://docs.aws.amazon.com/AmazonS3/latest/dev/ListingKeysUsingAPIs.html

Amazon S3 公开了一个列表操作可以让你枚举键装在一个桶里.键是选择按桶列出和字首.例如，考虑一个桶包含一个键的命名字典"对于每个英文单词.你可能会让调用以列出其中的所有键以字母q"开头的存储桶.列表结果始终返回字典(字母)顺序 列表结果总是以 UTF-8 二进制顺序返回.

Amazon S3 exposes a list operation that lets you enumerate the keys contained in a bucket. Keys are selected for listing by bucket and prefix. For example, consider a bucket named 'dictionary' that contains a key for every English word. You might make a call to list all the keys in that bucket that start with the letter "q". List results are always returned in lexicographic (alphabetical) order List results are always returned in UTF-8 binary order.
