Question

我正在尝试将文件上传到AWS s3存储桶。我不断收到此异常“ SdkClientException：无法执行HTTP请求：连接重置”。

我正在尝试通过inputstream上传

AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
                .withRegion(Regions.US_EAST_2)
                .withCredentials(new AWSStaticCredentialsProvider(cred))
                .build();
        try {

            ObjectMetadata metadata = new ObjectMetadata();
            metadata.setContentLength(bytesArray.length);
            metadata.setContentType("text/csv");
            s3Client.putObject(new PutObjectRequest(appConfig.getBucketName(), fileName, inStream, metadata).withCannedAcl(CannedAccessControlList.PublicRead));
        }
    ----

下面是详细的例外情况。可能是什么原因？我的S3存储桶具有具有S3完全访问策略的IAM用户。此问题与网络或任何其他设置有关吗？

Answer 1

我发现这是由于防火墙引起的。如果将DEBUG设置为logging.level.com.amazonaws，则它将显示SSL握手失败。

Answer 2

如果您在代理后面运行应用程序，则可能会发生这种情况。您可以将代理设置为，

public static void setProxy() {
        System.setProperty("http.proxyHost", "<http-proxy-url>");
        System.setProperty("http.proxyPort", "<port>");

        System.setProperty("https.proxyHost", "<https-proxy-url>");
        System.setProperty("https.proxyPort", "<port>");
    }
