在Amazon S3 bucket上上传文件时出错

Question

我正在尝试使用下面描述的无服务器架构在Amazon s3存储桶中上传文件

API网关-

我正在使用postman发送请求，图像被编码为base64格式，并在键“base64”中传递，然后将其转换为inputstream，并传入putObject方法，但在出现错误的地方，对于puObject方法，它表示NoSuchMethodError，但得到以下错误

错误堆栈跟踪：

使用方法：

public Object OperationHandler(MerchantSignUpRequest merchantSignUpRequest, Context context)
{   SignUpResponse signUpResponse=new SignUpResponse();
 LOG.info(new Gson().toJson(merchantSignUpRequest));

    AmazonS3 s3client = AmazonS3ClientBuilder.standard()
            .withCredentials(DefaultAWSCredentialsProviderChain.getInstance())
            .build();
    String timeStamp = new SimpleDateFormat("yyyy-MM-dd.HH:mm:ss").format(new java.util.Date());
    String bucketName="nownowhub";String name="12345678.jpg";
        InputStream is = new ByteArrayInputStream(merchantSignUpRequest.getBase64().getBytes());

        s3client.putObject(new PutObjectRequest(bucketName,name,is,new ObjectMetadata()).withCannedAcl(
                CannedAccessControlList.PublicRead));
        S3Object s3Object=s3client.getObject(new GetObjectRequest(
                bucketName,name));

        return (s3Object.getObjectContent().getHttpRequest().getURI().toString());
    }catch (Exception e)
    {
        e.printStackTrace();
        return "";
    }

请确保您使用的是相同版本的aws java sdk core和aws-java-sdk-s3，并且是最新版本，例如：-

<dependency>
        <groupId>com.amazonaws</groupId>
        <artifactId>aws-java-sdk-core</artifactId>
        <version>1.11.883</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/com.amazonaws/aws-java-sdk-s3 -->
    <dependency>
        <groupId>com.amazonaws</groupId>
        <artifactId>aws-java-sdk-s3</artifactId>
        <version>1.11.883</version>
    </dependency>
