我在尝试调试AWS Lambda函数时收到以下错误。
20:38:01.244 [main] DEBUG org.apache.http.wire - http-outgoing-0 << "HTTP/1.1 301 Moved Permanently[\r][\n]"
20:38:01.244 [main] DEBUG org.apache.http.wire - http-outgoing-0 << "x-amz-bucket-region: us-east-1[\r][\n]"
我的部分困惑是，我正在使用通常来自ap-south-1的桶，而实际上位于us-east-1，我真的不知道为什么us-east-1会出现在记录中。
我的代码是一个基本函数，在接收到S3 Put的触发器时，记录一些事情：
log.info("Lambda function is invoked: Processing the uploads........." + s3Event.toJson());
log.info("File - "+ FileName+" uploaded into "+BucketName+" bucket at "+ s3Event.getRecords().get(0).getEventTime());
try (InputStream is = s3client.getObject(BucketName, FileName).getObjectContent()) { log.info("File Contents : "+StreamUtils.copyToString(is, StandardCharsets.UTF_8));}
全部

private final String accessKeyId = System.getenv("accessKeyId");
private final String secretAccessKey = System.getenv("secretAccessKey");
private final String region = System.getenv("region");
private final BasicAWSCredentials basicAWSCredentials = new BasicAWSCredentials(accessKeyId, secretAccessKey);
AmazonS3 s3client = AmazonS3ClientBuilder
        .standard()
        .withRegion("ap-south-1")
        .withCredentials(new AWSStaticCredentialsProvider(basicAWSCredentials))
        .build();
static final Logger log = LoggerFactory.getLogger(S3EventHandler.class);

@Override
public String handleRequest(S3Event s3Event, Context context) {

    log.info("Lambda function is invoked: Processing the uploads........." + s3Event.toJson());

    String BucketName = s3Event.getRecords().get(0).getS3().getBucket().getName();
    String FileName = s3Event.getRecords().get(0).getS3().getObject().getKey();

    log.info("File - "+ FileName+" uploaded into "+
            BucketName+" bucket at "+ s3Event.getRecords().get(0).getEventTime());
    try (InputStream is = s3client.getObject(BucketName, FileName).getObjectContent()) {
        log.info("File Contents : "+StreamUtils.copyToString(is, StandardCharsets.UTF_8));
    }catch (IOException e){
        e.printStackTrace();
        return "Error reading contents of the file";
    }
    return null;
}

x1c 0d1x使用Toolkit插件的调试功能，我尝试模拟S3 Put。这会向S3 Function发送S3 Event，并记录所有内容：
lambdas3.S3EventHandler - Lambda function is invoked: Processing the uploads......... (etc)
lambdas3.S3EventHandler - File - HappyFace.jpg uploaded into source-bucket bucket at 1970-01-01T00:00:00.000Z
直到它运行到试图从bucket中获取文件的代码。我希望它返回文件的内容，或者返回一个错误，因为lambda函数只接收到事件，而对象没有在任何地方创建，
但是，它通知我某些内容已经被“301 Moved Permanently”和一些关于“x-amz-bucket-region：us-east-1”当一切都应该在ap-south-1中时
所以现在我很困惑为什么我的区域被改变了，为什么我得到的是这个错误，而不是我期望的两个结果之一。
