java - 访问被拒绝错误 imdb s3 存储桶

Question

我正在开发一个应用程序，它将使用名为“imdb-datasets”的亚马逊 aws s3 imdb 存储桶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，并设法将测试文件从我的 Android 设备上传和下载到我的存储桶，反之亦然。但是，在对 imdb-datasets 存储桶尝试相同的方法后，我开始收到访问被拒绝错误 403。经过一些研究，我发现可能的问题是我必须在代码中指定它是请求者付费存储桶。我尝试实现请求者付费位(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，因为我没有找到任何指南或解决方案。有什么想法如何做到这一点吗？

编辑:我还授予应用程序能够访问存储的权限，既可以通过 list ，也可以通过 Android 设备设置在应用程序中手动访问。还分配了 iam 用户和 imdb 存储桶的角色策略。

Files are located under documents/v1/*

在您的示例中， key 只是 title.basics.tsv.gz

在他们的代码示例中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);
