我试图在Unity内部的S3存储桶之间传输文件，遇到了我找不到文档的神秘错误。两个存储桶属于同一个帐户。

每当我创建资产时，我都会将其上传到Dev Bucket中的S3服务器，这非常有效。当我准备提交资产时，我想浏览Prod Bucket中缺失的资产列表，并将它们从Dev Bucket转移过来。根据我的研究，IAmazon onS3。CopyObjectAsync（）是应该执行此任务的函数。IAmazon onS3。CopyObject（）函数在Amazon的Unity SDK中不可用。

下面是我在尝试复制对象时调用的代码:

public void TestCopy()
{
    var request = new CopyObjectRequest()
    {
        SourceBucket = mLoginData.DevBucket,
        SourceKey =  "myPic.jpg",
        DestinationBucket = mLoginData.ProdBucket,
        DestinationKey = "myPic.jpg"
    };

    AWSConfigs.HttpClient = AWSConfigs.HttpClientOption.UnityWebRequest;

    Client.CopyObjectAsync(request,(responseObj) =>
    {
        if (responseObj.Exception == null)
        {
            ResultText.text += "Copied Object";
        }
        else
        {
            ResultText.text += "Got Exception: \n" + responseObj.Exception.ToString();
        }
    });
}

这会导致Amazon错误代码留档中未提及的“已移动”错误代码：

Got Exception: 
Amazon.S3.AmazonS3Exception: Error making request with Error Code Moved and Http Status Code Moved. No further error information was returned by the service. Response Body: Encountered invalid redirect (missing Location header?) ---> Amazon.Runtime.Internal.HttpErrorResponseException: Exception of type 'Amazon.Runtime.Internal.HttpErrorResponseException' was thrown.

我知道我的设置正确，因为我能够查看/列出存储桶，将文件上传/列出/删除到两个存储桶等。从 Unity 编辑器执行解决方案至关重要。
