考虑到你在AWS…我认为你会想要使用他们的CloudSearch工具。把你想要搜索的数据放到他们的服务中…让它指向S3密钥。

(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.

下面是一个使用AWS CLI搜索文件名的简短而丑陋的方法:

aws s3 ls s3://your-bucket --recursive | grep your-search | cut -c 32-

我是这样做的: 我在s3中有数千个文件。 我在列表中看到一个文件的属性面板。你可以看到该文件的URI，我复制粘贴到浏览器-这是一个文本文件，它呈现得很好。我用手边的uuid替换了url中的uuid文件就出来了。

我希望AWS有更好的方法来搜索文件，但这对我来说很管用。

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
