我想使用 AmazonAWS TransferManager 上传目录。我使用来自 TVM 的凭据成功创建了 AmazonS3Client。

当我尝试用它下载文件时，它抱怨：

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

AWS 错误代码：PermanentRedirect，AWS 错误消息：您尝试访问的存储桶必须使用指定的终端节点进行寻址。请将所有未来的请求发送到此端点

我已经阅读了有关该主题的内容，并且过去曾在其他编程语言中体验过它。我记得它与您在发出 S3 命令时执行最终“发布”的位置有关（我必须直接发布到我的存储桶 url）。但错误来自 AWS 开发工具包的深处，应该在那里处理。

我的存储桶位于 EU-WEST-1 区域。

我用

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，但我陷入了 AwS SDK 的数百万行和方法中。必须在某个地方正确设置端点，否则 sdk 将不适用于美国地区以外的存储桶。

帮助赞赏:)

您需要设置与创建存储桶的位置匹配的端点。

例如：如果“mybucket”是在 EU 下创建的，那么对于您正在创建的 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端点：http: //docs.aws.amazon.com/general/latest/gr/rande.html#s3_region

对于来自不同地区、不同端点的用户可以参考： 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;
    }
