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 S3 兼容对象存储服务中上传文件。该程序在 Windows 我的本地机器上运行良好，但是当我（当然在更改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，我收到以下错误 -

> 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第二部分，因为存储桶列表在 linux env 中返回。同样，但在文件上传过程中它抛出错误。

逆天！你知道 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&nbsp;s3,&nbsp;String&nbsp;bucketName,&nbsp;String&nbsp;objectName,&nbsp;String&nbsp;pathName)其中 pathName 是文件的路径，即String&nbsp;pathName&nbsp;=&nbsp;"/home/abc/xxxxx/objectStorage/errorlog.txt";注意它以正斜杠开头，而对象名称不应以/ie开头String&nbsp;objectName&nbsp;=&nbsp;"home/abc/xxxxxx/objectStorage/errorlog.txt";我希望抛出的异常能够更清楚地说明出了什么问题。抛出的异常只会让我偏离根本原因。
