带有https连接的亚马逊S3 SDK

Question

我的当前用于在S3存储桶上复制对象的基于REST的访问的代码不起作用。我的S3存储桶配置为https访问，并启用了sse。我如何修改下面的代码使其工作？ 目前，我只是收到一条错误消息'Caught a AmazonClientException，这意味着客户端在尝试与S3通信时遇到错误，例如无法访问网络。 错误消息：无法执行的HTTP请求：mybucket.s3.amazonaws.com”

@PUT 
    @Path("/copy/{bucketName}") 
    public void copyObject(@PathParam("bucketName") String bucketName, @QueryParam("fromPath") String fromPath, 
      @QueryParam("toPath") String toPath) throws AmazonClientException { 

     AmazonS3 s3client = new AmazonS3Client(new DefaultAWSCredentialsProviderChain()); 
     try { 

      CopyObjectRequest copyObjRequest = new CopyObjectRequest(bucketName, fromPath, bucketName, toPath); 
      System.out.println("Copying object."); 

      s3client.copyObject(copyObjRequest); 

     } catch (AmazonServiceException ase) { 
      System.out.println("Caught an AmazonServiceException, " + "which means your request made it " 
        + "to Amazon S3, but was rejected with an error " + "response for some reason."); 
      System.out.println("Error Message: " + ase.getMessage()); 
      System.out.println("HTTP Status Code: " + ase.getStatusCode()); 
      System.out.println("AWS Error Code: " + ase.getErrorCode()); 
      System.out.println("Error Type:  " + ase.getErrorType()); 
      System.out.println("Request ID:  " + ase.getRequestId()); 
     } catch (AmazonClientException ace) { 
      System.out.println("Caught an AmazonClientException, " + "which means the client encountered " 
        + "an internal error while trying to " + " communicate with S3, " 
        + "such as not being able to access the network."); 
      System.out.println("Error Message: " + ace.getMessage()); 
     } 
    }

解决它。这最终成为代理问题。为了克服这个问题，我必须做到以下几点。当我克服网络问题时，我有另一个异常要求我设置S3端点。下面的代码更改。

public static final String PROXY_HOST = "<my proxy hostname>"; 
public static final int PROXY_PORT = <my_proxy_port>; 
public static final String S3_ENDPOINT = "https://s3.amazonaws.com"; 

ClientConfiguration clientCfg = new ClientConfiguration(); 
clientCfg.setProtocol(Protocol.HTTP); 
clientCfg.setProxyHost(PROXY_HOST); 
clientCfg.setProxyPort(PROXY_PORT); 

AmazonS3 s3Client = new AmazonS3Client(new DefaultAWSCredentialsProviderChain(), clientCfg); 

s3Client.setEndpoint(S3_ENDPOINT); 
s3Client.setRegion(Region.getRegion(Regions.US_EAST_1));
