我很困惑我在这里做错什么

function GMTNow(){return new Date().toGMTString()}
</script>
<%
Const AWS_BUCKETNAME = "uk-bucketname"

LocalFile = Server.Mappath("/test.jpg")
Dim sRemoteFilePath

Dim strNow
strNow = GMTNow() ' GMT Date String
Dim StringToSign
StringToSign = Replace("PUT\n\nimage/jpeg\n\nx-amz-date:" & strNow & "\n/"& AWS_BUCKETNAME & sRemoteFilePath,"\n",vbLf)
Dim Signature
Signature = BytesToBase64(HMACSHA1(AWS_SECRETKEY,StringToSign))

Authorization = "AWS " & AWS_ACCESSKEY & ":" & Signature

AWSBucketUrl = "http://s3.amazonaws.com/" & AWS_BUCKETNAME

现在得到错误.
@H_403_2@msxml3.dll error '800c0008' The download of the specified resource has Failed. /s3.asp,line 39解决方法
我想解释一下S3 Rest Api如何工作,就我所知.首先,你需要学习什么应该是字符串签署亚马逊接受.
格式：
@H_403_2@StringToSign = HTTP-Verb + "\n" + Content-MD5 + "\n" + Content-Type + "\n" + Date + "\n" + CanonicalizedAmzHeaders + CanonicalizedResource;生成有符号的字符串：
@H_403_2@Signature = Base64( HMAC-SHA1( YourSecretAccessKeyID,UTF-8-Encoding-Of( StringToSign ) ) );传递授权标题：
@H_403_2@Authorization = "AWS" + " " + AWSAccessKeyId + ":" + Signature;不幸的是,你会播放字节到字节,因为没有任何SDK发布经典的asp.所以,应该通过阅读整个页面http://docs.amazonwebservices.com/AmazonS3/latest/dev/RESTAuthentication.html来了解
对于字符串进行签名,您可以在上面看到格式,API有三个本机头. Content-Type,Content-MD5和Date.这些标头必须存在于字符串中,即使您的请求没有标头名称也不是空的,只是其值.有一个例外,如果请求中已经存在x-amz-date头,则字符串中的Date标头必须为空.然后,如果请求具有规范的亚马逊标头,则应将其添加为键值对,如x-amz-headername：value.但是,还有一个例外需要考虑多个头.多个标题应该组合成一个标题,并用逗号分隔.
正确
x-amz-headername:value1,value2
x-amz-headername:value1\n
x-amz-headername:value2
最重要的是,标头必须按其字符串中的组的升序顺序进行签名.首先,按照升序排列保留标题,然后按规则标题升序.
我建议使用DomDocument功能来生成Base64编码的字符串.
另外,除了Windows脚本组件(.wsc文件)之外,您可以使用.Net的Interops(如System.Security.Cryptography)来更有效地利用System.Text的功能生成密钥哈希.所有这些互操作性在当今的IIS Web服务器中都可用.
所以,作为一个例子,我写下面的脚本只是发送一个文件到你指定的桶.考虑和测试
假设本地文件名为myimage.jpg,并将以相同的名称上传到存储桶的根目录.
