AmazonS3Exception：仅在Linux远程服务器中请求签名错误？

Question

我编写了一个Java程序来列出所有存储桶，并在与S3兼容的对象存储服务中上传文件。 该程序在本地计算机的Windows中运行正常，但是当我（当然更改了要上传的文件的路径之后）在远程linux服务器中传输可运行的jar并执行它时，出现以下错误-

> Exception in thread "main"
> com.amazonaws.services.s3.model.AmazonS3Exception: The request
> signature we calculated does not match the signature you provided.
> Check your AWS Secret Access Key and signing method. For more
> information, see REST Authentication and SOAP Authentication for
> details. (Service: Amazon S3; Status Code: 403; Error Code:
> SignatureDoesNotMatch; Request ID:
> 4e271b5b-d7f5-42b3-a4ad-886988bcb785; S3 Extended Request ID: null),
> S3 Extended Request ID: null

问题似乎出在程序的后半部分，因为bucket列表正在linux env中返回。 同样，但是在文件上传过程中会引发错误。

    final String secretKey = "XXXXXXXXXXXXXXXXXXXXXXXX";
    BasicAWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
    @SuppressWarnings("deprecation")
    final AmazonS3 s3 = new AmazonS3Client(credentials);
    S3ClientOptions opts = new S3ClientOptions().withPathStyleAccess(true);
    s3.setS3ClientOptions(opts);

    s3.setEndpoint("https://XXXXXX.com");
    ListBuckets.time("startTime");
    ListBuckets.listObjects(s3);
    //String pathName = "C:\\Users\\XXXXXX\\Documents\\New folder\\New Text Document - Copy.txt";
    String pathName = "/home/abcd/XXXXX/objectStorage/CHANGELOG.mdown";
    ListBuckets.putObject(s3, "snap-shot/sample-aws-ex", pathName, pathName);
    ListBuckets.time("end time");
}

}`

难以置信的！ 您知道linux的问题是什么吗？ 对象名和路径名是两个不同的东西。

putObject(AmazonS3 s3, String bucketName, String objectName, String pathName)

其中pathName是文件的路径，即

String pathName = "/home/abc/xxxxx/objectStorage/errorlog.txt";

注意，它以正斜杠开头，而对象名称不应以/即开头

String objectName = "home/abc/xxxxxx/objectStorage/errorlog.txt";

我希望抛出的异常会更好地说明问题所在。 引发的异常仅使我偏离了根本原因。
