(至少)有两个不同的用例可以描述为“搜索桶”:

Search for something inside every object stored at the bucket; this assumes a common format for all the objects in that bucket (say, text files), etc etc. For something like this, you're forced to do what Cody Caughlan just answered. The AWS S3 docs has example code showing how to do this with the AWS SDK for Java: Listing Keys Using the AWS SDK for Java (there you'll also find PHP and C# examples). List item Search for something in the object keys contained in that bucket; S3 does have partial support for this, in the form of allowing prefix exact matches + collapsing matches after a delimiter. This is explained in more detail at the AWS S3 Developer Guide. This allows, for example, to implement "folders" through using as object keys something like folder/subfolder/file.txt If you follow this convention, most of the S3 GUIs (such as the AWS Console) will show you a folder view of your bucket.

我尝试了以下方法

aws s3 ls s3://Bucket1/folder1/2019/ --recursive |grep filename.csv

这将输出文件存在的实际路径

2019-04-05 01:18:35     111111 folder1/2019/03/20/filename.csv

2018 - 07年现状: 亚马逊有本地sql像搜索csv和json文件!

快进到2020年，使用aws-okta作为我们的2fa，下面的命令，尽管迭代这个特定bucket(+270,000)中的所有对象和文件夹非常缓慢，但运行良好。

aws-okta exec dev -- aws s3 ls my-cool-bucket --recursive | grep needle-in-haystax.txt

S3没有原生的“搜索此桶”，因为实际内容是未知的-此外，由于S3是基于键/值的，因此没有原生的方法可以一次访问多个节点，而更传统的数据存储提供了一个(SELECT * FROM…(在SQL模型中)。

您需要做的是执行ListBucket以获得bucket中对象的列表，然后遍历每个项，执行您实现的自定义操作—这就是您的搜索。
