Java 将流上载到AmazonS3

这是我面临的一个例外=

java.net.URLConnection conn = null;
try
{
    conn = new URL(track.getStreamUrl()).openConnection();
}
catch(MalformedURLException e1)
{

    e1.printStackTrace();
}
catch(IOException e1)
{

    e1.printStackTrace();
}

try
{
    InputStream is = conn.getInputStream();
    byte[] contentbytes = getBytesFromInputStream(is);
    Long contentLength = Long.valueOf(contentbytes.length);
    ObjectMetadata metadata = new ObjectMetadata();
    metadata.setContentLength(contentLength);
    InputStream is2 = conn.getInputStream();
    s3.putObject(new PutObjectRequest(bucketName, my_key, is2, metadata));
}

您得到了一个HTTP重定向响应——正如错误消息所说，您必须使用该地址，而不是实际连接的位置。或者，您可以执行以下操作：

您尝试上载到的bucket是在不同于“美国标准”的地区创建的。创建S3Client对象时，需要指定正确的区域。在AWS SDK for Java的1.4版本中，您可以执行以下操作：

java.net.HttpURLConnection conn = null;
try
{
    URL url = new URL(track.getStreamUrl());
    conn = (HttpURLConnection)url.openConnection();
    conn.setFollowRedirects(true);
}
catch(MalformedURLException e1)
{
    e1.printStackTrace();
}
catch(IOException e1)
{

    e1.printStackTrace();
}

AmazonS3 s3 = new AmazonS3Client();
s3.setRegion(Region.getRegion(Regions.US_WEST_2)); // or whatever region you are working with

或者你可以：

java.net.HttpURLConnection conn = null;
try
{
    URL url = new URL(track.getStreamUrl());
    conn = (HttpURLConnection)url.openConnection();
    conn.setFollowRedirects(true);
}
catch(MalformedURLException e1)
{
    e1.printStackTrace();
}
catch(IOException e1)
{

    e1.printStackTrace();
}

AmazonS3 s3 = new AmazonS3Client();
s3.setRegion(Region.getRegion(Regions.US_WEST_2)); // or whatever region you are working with

你能发布线级日志吗？
