嗨,我试图以编程方式禁用API密钥,但找不到任何文档.

到目前为止,我找到了可能是我需要的2个类:

UpdateApiKeyRequest和DeleteApiKeyRequest.问题是我不知道如何处理这些问题.

请有人告诉我如何使用这些类来禁用或删除API密钥？

我正在使用 Amazon Java SDK（在撰写本文时最新版本为 1.11.147）和 Groovy（Groovy 版本：2.4.11 JVM：1.8.0_112 供应商：Oracle Corporation OS：Mac OS X）将文件上传到 S3。使用 Amazon 文档中关于Transfer Manager 的说明，我能够将内容从一个存储桶复制到另一个存储桶。但是，上传总是失败。我尝试了以下3种方法。我让 Grapes 抓取了 httpclient 和 httpcore 的新版本，因为我在这个 Stack Overflow Post Apache PoolingHttpClientConnectionManager throwing非法状态异常中读到了什么

@Grapes([
  @Grab(group='com.amazonaws', module='aws-java-sdk', version='1.11.147'),
  // https://mvnrepository.com/artifact/org.apache.commons/commons-compress
  @Grab(group='org.apache.commons', module='commons-compress', version='1.13'),
  // https://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient
  @Grab(group='org.apache.httpcomponents', module='httpclient', version='4.5.3'),
  // https://mvnrepository.com/artifact/org.apache.httpcomponents/httpcore
  @Grab(group='org.apache.httpcomponents', module='httpcore', version='4.4.6')
])

// creds is String saying which ~/.aws/credentials profile to use
def credentials = new ProfileCredentialsProvider(creds)

def s3client  = AmazonS3ClientBuilder.standard().
                withCredentials(credentials).
                withRegion(region).
                build()
def tx = TransferManagerBuilder.standard().
         withS3Client(s3client). …

我正在尝试使用 aws-java-sdk 版本 1.11.339 从 AWS 获取 ECR 授权令牌。我创建了一个类来这样做：

public class ECRTokenGetter {
    private static final Logger LOGGER = LoggerFactory.getLogger(ECRTokenGetter.class);
    private static final int SINGLE_ELEMENT_INDEX = 0;


    public static String getEcrAuthorisationToken(Credentials creds, String awsRegion, String registryId) {
        LOGGER.debug("Obtaining temporary authorisation credentials from AWS ECR");

        AmazonECR ecrClient = AmazonECRClientBuilder.standard()
                .withRegion(awsRegion)
                .withCredentials(new AWSStaticCredentialsProvider(new BasicSessionCredentials(
                        creds.getAccessKeyId(),
                        creds.getSecretAccessKey(),
                        creds.getSessionToken())))
                .build();
        return ecrClient.getAuthorizationToken(new GetAuthorizationTokenRequest()
                        .withRegistryIds(registryId))
                .getAuthorizationData().get(SINGLE_ELEMENT_INDEX)
                .getAuthorizationToken();
    }
}

不幸的是，在执行代码时，我收到以下异常：

Exception in thread "main" java.lang.IllegalArgumentException: hostname cannot be null
    at com.amazonaws.util.AwsHostNameUtils.parseRegion(AwsHostNameUtils.java:79)
    at com.amazonaws.util.AwsHostNameUtils.parseRegionName(AwsHostNameUtils.java:59)
    at com.amazonaws.auth.internal.AWS4SignerRequestParams.resolveRegion(AWS4SignerRequestParams.java:121) …

我按照https://docs.aws.amazon.com/AmazonS3/latest/dev/ShareObjectPreSignedURLJavaSDK.html中的示例创建预签名 s3 url (v4)，当我尝试访问已签名的 s3 url (v4) 时，出现“访问被拒绝”错误网址

<Error>
   <Code>AccessDenied</Code>
   <Message>Access Denied</Message>
   <RequestId>0FB02ECDDF5EAC7B</RequestId>

</Error>

以下是代码片段

public class GeneratePresignedURL {

    public static void main(String[] args) throws IOException {
        String clientRegion = "us-east-1";
        String bucketName = "com-example-bucket";
        String objectKey = "path/to/file.img"; // No leading `/`
        // https://com-example-bucket.s3.amazonaws.com/path/to/file.img

        try { 
            AWSCredentialsProvider awsCredentialsProvider = new DefaultAWSCredentialsProviderChain();

            // Assuming that us-east-1 defaults to v4, couldn't find a way to set it explicitly
            AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
                    .withRegion(clientRegion)
                    .withCredentials(awsCredentialsProvider)
                    .build();

            // Set …

我想认为这是个不错的选择，但我想先提出询问。因此，您知道我从S3存储桶下载文件或向S3存储桶上传文件时，适用于Java的AWS开发工具包是否始终使用安全通道吗？还是在编写代码时或在S3存储桶本身中应该配置的东西？

我们正在将文件上传到 Amazon S3，我想添加一个功能来显示文件中的行数。如何在不下载的情况下获取 S3 上 csv 文件的行数？

我想旋转AWS IAM用户访问密钥，仅旋转访问密钥，而不旋转秘密访问密钥，当我尝试旋转密钥时，我能够旋转整个密钥，而不是单独访问密钥。

我正在玩一个在 docker 上运行的 localstack 实例。我尝试访问 sns 服务，但在执行“listTopics()”或“createTopic()”等方法时收到错误我还没有在 Google 上找到任何帮助，所以有人知道这里出了什么问题吗？

错误：
