我正在使用 java 代码连接到 amazon s3。每次尝试连接到 S3 时，我都会收到 HttpHostConnection denied 错误。在 S3 上，作为所有者，我只有一个拥有所有权限的存储桶。每当我尝试列出存储桶中的文件或尝试在 S3 上上传文件时，都会出错。

代码如下：

    TransferManager tx = new TransferManager(credentials);  
    Upload upload = tx.upload("bucket.name", doc.getFileName(),                 new File("C:\\testing2.pdf"));   
    while (upload.isDone() == false) {     
       System.out.println(upload.getProgress().getPercentTransferred() + "%"); 
    }

经过2个月的努力，我找到了解决方案。在这里，我们需要检查我们网络中的代理设置。我只是创建了 ClientConfig 并将代理属性设置为这个对象。我使用 putObjectRequest 方法上传对象。这是一个代码

ClientConfiguration clientConfig = new ClientConfiguration();
clientConfig.setProtocol(Protocol.HTTPS);
clientConfig.setProxyHost(ip_address);
clientConfig.setProxyPort(port number);
clientConfig.setProxyUsername(user id on network);
clientConfig.setProxyPassword(password on network);

AmazonS3 s3 = new AmazonS3Client(new BasicAWSCredentials("access key", "secret key"),
clientConfig);
file = new File(fileName);
PutObjectRequest putObject = new PutObjectRequest(bucketName, fileName, file);
ObjectMetadata metaData = new ObjectMetadata();
metaData.setContentType("application/pdf"); //binary data
putObject.setMetadata(metaData);
s3.putObject(putObject);

如果您拥有正确的 ACCESS_KEY 和 SECRET_KEY 以连接到 AWS S3，则可能需要检查您的凭证。您可以通过 IAM 管理控制台中的安全凭证获取它。

To augment the above answer, I've encountered this also due to routing/DNS issues (usually showing as a nested UnknownHostException)

  • do an nslookup of the s3 URI (e.g., nslookup s3.amazonaws.com)
  • if you're on a VPN, make sure it's actually working (since many can show "active" while being hung up on the remote end, especially on VMs). an incorrect/failed nslookup should show this as well

当你设置你的AmazonS3对象时，你传入一个ClientConfiguration对象。

例如：

ClientConfiguration clientConfig = new ClientConfiguration();
clientConfig.withProtocol(Protocol.HTTPS);
clientConfig.withProxyHost(ip_address);
clientConfig.withProxyPort(port number);
clientConfig.withProxyUsername(user id on network);
clientConfig.withProxyPassword(password on network);

AmazonS3 s3Client= AmazonS3ClientBuilder.standard().withClientConfiguration(clientConfig)...;

您的 .withProxyHost() 值错误。

就我而言，这是一个代理问题。在 TS3Connection 组件上，在高级设置中，我使用客户端参数检查了配置客户端：代理主机、代理端口并且它工作
