访问被拒绝错误imdb s3存储桶

Question

我正在使用名为“imdb-datasets”的亚马逊aws s3 imdb存储区来显示各种电影信息。在尝试此操作之前，我使用自己的存储桶测试了代码，并设法从Android设备上传和下载测试文件到我的存储桶，反之亦然。但在尝试使用imdb-datasets桶的同样方法时，我开始接受拒绝403的错误。在做了一些研究之后，我发现可能的问题是我必须在代码中指定它是请求者支付的存储桶。我试图实现请求者支付位（注释掉的代码），但它使我的应用程序崩溃。我不知道如何在我的应用程序中实现它，因为我无法找到任何指南或解决方案。任何想法如何做到这一点？

编辑：我也给了应用程序的权限，以便能够通过Android设备设置通过清单和手动在应用程序中访问存储。还分配了与iam用户和imdb存储桶的角色策略。

文件位于文件/ V1/*

在你的榜样，关键是只是title.basics.tsv.gz

在他们的代码示例here

private static String bucketName = "imdb-datasets"; 
private static String key  = "documents/v1/current/name.basics.tsv.gz";  

public static void main(String[] args) throws IOException, InterruptedException { 
    ProfileCredentialsProvider credentialsProvider = 
      new ProfileCredentialsProvider("*** FULL PATH TO AWS CREDENTIALS FILE ***", 
              "*** CREDENTIALS PROFILE NAME ***"); 

    AmazonS3 s3Client = new AmazonS3Client(credentialsProvider); 

    try { 
     // Note: It's necessary to set RequesterPays to true 
     GetObjectRequest getObjectRequest = new GetObjectRequest(bucketName, key) 
               .withRequesterPays(true);
