java AWS S3 getObject() 导致 HTTP 连接超时

AWS S3 getObject() causing HTTP Connection Time Out

提问by nLee

I am trying to retrieve a File (asdf.txt) that I manually uploaded to my AWS S3 Bucket. Let's call it "myBucket". I have set the permissions on the bucket and the file to be completely accessible to all. When I call getObject()I get the an error saying that the Connection timed out. Here is my stacktrace:

我正在尝试检索我手动上传到我的 AWS S3 存储桶的文件 (asdf.txt)。我们称之为“myBucket”。我已将存储桶和文件的权限设置为所有人都可以完全访问。当我打电话时，getObject()我收到一个错误，说Connection timed out. 这是我的堆栈跟踪：

here is my code:

这是我的代码：

public static void main(String[] args) {
    AmazonS3Client s3 = new AmazonS3Client();
    s3.setEndpoint("s3.amazonaws.com");
    s3.setRegion(Region.getRegion(Regions.US_WEST_1));
    S3Object obj = s3.getObject(new GetObjectRequest("myBucket", "asdf.txt"));
    System.out.println(obj.getBucketName());
}

I have also tried it a few different ways. The modified lines are shown below:

我也尝试了几种不同的方法。修改后的行如下所示：

s3.setEndpoint("https://myBucketName.s3.amazonaws.com");

S3Object obj = s3.getObject("myBucket", "asdf.txt");

Can anyone tell me what I am doing wrong?

谁能告诉我我做错了什么？

Turns out it was a proxy issue. I just needed to specify the proxy configuration and instantiate the client with the configurations and it worked

原来是代理问题。我只需要指定代理配置并使用配置实例化客户端就可以了

AwsSyncClientBuilder builder =  AmazonS3ClientBuilder.standard();

ClientConfiguration cc = new ClientConfiguration();
cc.setProxyHost("<proxyAddress>");
cc.setProxyPort(<proxyPort>);

AWSCredentialsProvider credentials = new DefaultAWSCredentialsProviderChain();

AmazonS3Client s3 = (AwsSyncClientBuilder) builder
        .withClientConfiguration(cc)
        .withCredentials(credentials)
        .withRegion(Regions.US_EAST_1);

U have to configure AmazonS3Client with following properties:

您必须使用以下属性配置 AmazonS3Client：

1. connectionTimeout=50000 in ms
2. maxConnections=500
3. socketTimeout=50000 in ms
4. maxErrorRetry=10

1. 连接超时 = 50000 毫秒
2. 最大连接数=500
3. socketTimeout=50000 毫秒
4. 最大错误重试=10

And don't use Transfermanagerfor upload and download Use:

并且不要Transfermanager用于上传和下载使用：

AmazonS3Client(AWSCredentials awsCredentials, ClientConfiguration clientConfiguration)
