Java 连接到Amazon S3时获取HttpHostConnection拒绝错误

java amazon-web-services amazon-s3

Java 连接到Amazon S3时获取HttpHostConnection拒绝错误,java,amazon-web-services,amazon-s3,Java,Amazon Web Services,Amazon S3,我正在使用java代码连接AmazonS3。每次尝试连接到S3时，我都会收到HttpHostConnection拒绝错误。在S3上，作为所有者，我只有一个bucket拥有所有权限。每当我尝试在bucket中列出文件或尝试在S3上上传文件时，我都会遇到错误代码如下： TransferManager tx = new TransferManager(credentials); Upload upload = tx.upload("bucket.name", doc.getFil

我正在使用java代码连接AmazonS3。每次尝试连接到S3时，我都会收到HttpHostConnection拒绝错误。在S3上，作为所有者，我只有一个bucket拥有所有权限。每当我尝试在bucket中列出文件或尝试在S3上上传文件时，我都会遇到错误

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() + "%"); 
    }

如果您拥有正确的访问密钥和密钥以连接到AWS S3，则可能需要检查您的凭据。您可以通过IAM管理控制台中的安全凭据获取此信息。

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

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);

为了补充上述答案，我也遇到了路由/DNS问题（通常显示为嵌套的UnknownHostException）

对S3URI进行nslookup（例如，
```
nslookup s3.amazonaws.com
```
）
如果您使用的是VPN，请确保它实际工作（因为许多VPN在远程端挂起时会显示“活动”，特别是在虚拟机上）。错误/失败的nslookup也应显示这一点
