Question

我目前正在制作一个简单的React本机应用程序。因此，我从图库中挑选了一些图像，然后使用AWS Lambda函数（Java）将其上传到S3存储桶中。但是每当我尝试将这些图像上传到s3存储桶时，我都会不断收到没有此类文件或目录异常，并将其保存为0字节大小的文本文件格式。

package com.amazonaws.lambda.demo;
import java.io.File;
import java.io.IOException; 
import com.amazonaws.AmazonServiceException;
import com.amazonaws.SdkClientException;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.RequestHandler;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3Client;
import com.amazonaws.services.s3.model.PutObjectRequest;
import com.amazonaws.services.s3.model.PutObjectResult;

public class LambdaFunctionHandler implements RequestHandler<String, PutObjectResult> {
@SuppressWarnings("deprecation")
public PutObjectResult UploadFile(String imageURI) throws IOException {

    PutObjectResult resultObj = new PutObjectResult();
    AWSCredentials credentials = new BasicAWSCredentials("Ak", "Sk");
    //String clientRegion = "region";
    String bucketName = "bucket_name";
    String fileObjKeyName = "sample_image_pic.jpg";

    try {
        AmazonS3 s3Client = new AmazonS3Client(credentials);

        // Upload a file as a new object with ContentType and title specified.

        resultObj = s3Client.putObject(new PutObjectRequest(bucketName, fileObjKeyName, new File(imageURI)));
    }
    catch(AmazonServiceException e) {
        // The call was transmitted successfully, but Amazon S3 couldn't process 
        // it, so it returned an error response.
        e.printStackTrace();
    }
    catch(SdkClientException e) {
        // Amazon S3 couldn't be contacted for a response, or the client
        // couldn't parse the response from Amazon S3.
        e.printStackTrace();
    }

    return resultObj;
}

@Override
public PutObjectResult handleRequest(String imageURI, Context context) {

    PutObjectResult result = null;
    try {
        result = UploadFile(imageURI);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return result;
}

}

对于这些概念，我也很陌生，如果我做错了什么，请纠正我。

谢谢

AWS Lambda Java函数中没有此类文件或目录异常
