列出S3上的文件 [英] List files on S3

问题描述

我对如何列出S3存储桶中的所有文件找不到任何好的解释感到沮丧.

I'm getting frustrated by not finding any good explanation on how to list all files in a S3 bucket.

我有大约20张图像的存储桶.我要做的就是列出它们.有人说只是使用S3.list方法".但是没有任何特殊的库，就没有S3.list方法. 我有一个S3.get方法，但我无法正常工作. Arggh，如果有人告诉我如何简单地从S3存储桶中获取所有文件(文件名)的列表，我们将不胜感激.

I have this bucket with about 20 images on. All I want to do is to list them. Someone says "just use the S3.list-method". But without any special library there is no S3.list-method. I have a S3.get-method, which I dont get to work. Arggh, would appreciate if someone told me how to simply get an list of all files(filenames) from an S3 bucket.

val S3files = S3.get(bucketName: String, path: Option[String], prefix: Option[String], delimiter: Option[String])

返回未来[响应]

我不知道如何使用此S3.get. 列出S3存储桶中所有文件的最简单方法是什么?

I dont know how to use this S3.get. What would be the easiest way to list all files in my S3 bucket?

非常感谢！

推荐答案

在此处使用库:

您应该可以执行以下操作:

You should be able to do something like this:

import concurrent.ExecutionContext.Implicits._

val bucket = S3("bucketName")
val result = bucket.list
result.map {
  case Left(error) => throw new Exception("Error: " + x)
  case Right(list) => 
    list.foreach {
        case BucketItem(name, isVirtual) => //...
    }
}

您必须对凭据进行一些调整，但是示例显示了如何做到这一点.

You'll have to tweak this a bit in regards to your credentials, but the examples show how to do that.
