Question

我想使用AmazonAWS TransferManager上传目录。我成功创建了一个包含来自TVM的凭据的AmazonS3Client。

当我尝试用它下载文件时，它会抱怨：

final MultipleFileDownload fileDownloadd=mTransferManager.downloadDirectory(ChanAuth.getBucketName(), remotePath, file);

AWS错误代码：PermanentRedirect，AWS错误消息：您尝试访问的存储区必须使用指定的端点进行寻址。请将以后的所有请求发送到此终端

我已经阅读过这个主题，过去在其他编程语言中经历过这个主题。我记得在发出S3命令时你在最后的“帖子”的位置有关系（我必须直接发布到我的桶URL）。但是错误来自AWS SDK的深层，应该在那里处理。

我的水桶位于EU-WEST-1地区。

我用

初始化客户端

s3Client.setRegion(Regions....(Region.EU_WEST_1))

和

s3Client.setEndpoint("s3-eu-west-1.amazonaws.com");

但我总是让TransferManager抱怨。

我怀疑这一定是一个愚蠢的问题，但我会陷入AwS SDK的百万行和方法中。必须在某处正确设置端点，否则sdk不适用于美国以外的存储区。

帮助感谢：）

Answer 1

您需要设置与创建存储桶的位置匹配的端点。

例如：如果在EU下创建“mybucket”，则对于您正在创建的s3client，应将端点设置为“s3-eu-west-1.amazonaws.com”。

同样，根据您的存储桶的创建位置，您可以根据此页面设置出点：http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region

Answer 2

对于来自不同地区的用户，使用不同的端点可以参考：的 http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region

如果您不知道您的端点到底是什么，您可以遍历所有端点并尝试每个端点，并在正确的端点上进行归零。

private String[] endPoints = new String[] { "s3.amazonaws.com", "s3-external-1.amazonaws.com", "s3-us-west-2.amazonaws.com", "s3-us-west-1.amazonaws.com", "s3-eu-west-1.amazonaws.com", "s3-ap-southeast-1.amazonaws.com", "s3-ap-southeast-2.amazonaws.com", "s3-ap-northeast-1.amazonaws.com", "s3-sa-east-1.amazonaws.com" }; private int currentIndex = 0; protected S3TaskResult upload(String filePath) { String endPoint = endPoints[currentIndex++]; S3TaskResult result = new S3TaskResult(); // Put the image data into S3. try { // s3Client.createBucket(Constants.getPictureBucket());" s3Client.setEndpoint(endPoint); // Content type is determined by file extension. PutObjectRequest por = new PutObjectRequest( Constants.getPictureBucket(), Constants.PICTURE_NAME, new java.io.File(filePath)); por.setProgressListener(this); s3Client.putObject(por); Log.d("S3","SUCCESSFUL ENDPOINT : "+endPoint); // GOT IT!! } catch (Exception exception) { if (currentIndex < endPoints.length) { upload(filePath); } exception.printStackTrace(); } return result; }
