如何为AWS Import API请求生成签名？

按照AWS导入API文档的要求是这样的：如何为AWS Import API请求生成签名？

POST/HTTP/1.1 
content-type:application/x-www-form-urlencoded;charset=utf-8 
host: https://importexport.amazonaws.com 
content-length:356 

Operation=CreateJob&Manifest=manifestVersion%3A%202.0%0Abucket%3A%20myBucket

country%3A%20USA&JobType=Import&AWSAccessKeyId=1111729HYRYMYRB3FK02& 
SignatureVersion=2&SignatureMethod=%2FVfkltRBOoSUi1sWxRzN8rw%3D

正如你可以看到主体数据的最后一个参数是是SignatureMethod。但它看起来像签名。我发现了SignatureMethod的两个可用值。他们是HmacSHA1和HmacSHA256。

为了生成Signature查询字符串，我使用了aws/s3 gem，最后我得到了类似前一个请求的请求，但最后发生了很小的变化。

但是，响应仍然是403禁止。

你可以找到我用来测试这个位置http://gist.github.com/581726

请告诉我出了什么问题，以及如何正确地生成签名的代码。

我不知道这种宝石做什么，但一个基本的签署是这样的：

aws_secret = 'foo' # aws provides this 

query_string = 'Operation=CreateJob&Manifest=...' # this is for your api call 

hmac = HMAC::SHA256.new(aws_secret) 
hmac.update(query_string) 
signature = Base64.encode64(hmac.digest).chomp

BTW：既然你在这里分享你的快捷键，您应该重新生成凭证。
