PHP亚马逊文件上传签名

我尝试了文件上传到我的Amazon S3闯民宅本教程 http://www.anyexample.com/programming/php/uploading_files_to_amazon_s3_with_rest_api.xml PHP亚马逊文件上传签名

但我得到了以下错误

是'我们出的要求签名不匹配您提供的签名。检查你的密钥和签名方法.'不清楚了吗？ –

他们以下是签名方法...你能帮忙吗？ $ dt = gmdate（'r'）; //基于GMT的时间戳 //准备要签名的字符串（请参阅AWS S3开发人员指南） $ string2sign =“PUT {$ dt}/{$ aws_bucket}”; //准备HTTP PUT查询 $查询=“PUT/{$ aws_bucket} HTTP/1.1 主持人：s3.amazonaws.com 连接：保持活跃日期：$ DT 授权：AWS {$ aws_key}： ” .amazon_hmac（string2sign $） “\ n \ n”; $ RESP = sendREST（$ FP，$查询）; 如果（strpos（$ RESP， ''）==假的！）{ 模具（$ RESP）; } – ramesh

你有你自己的AWS访问密钥ID和秘密访问键？ –

无有你的代码，查看它的努力帮助，但这里是一些示例代码，您可能会发现有用：

class myS3Helper{ 
public function getSignedImageLink($timeout = 1800, $my_aws_secretkey, $my_aws_key) 
{ 

    $now = new Zend_Date(); //Gives us a time object that is set to NOW 
    $now->setTimezone('UTC'); //Set to UTC a-la AWS requirements 
    $now->addSecond($timeout); //set the time in the time object to a point in the future 
    $expirationTime = $now->getTimestamp(); //returns unix timestamp representation of the time. 

    $signature = urlencode(
      base64_encode(
        hash_hmac(
          'sha1', $this->_generateStringToSign($expirationTime), 
          $my_aws_secretkey, 
          true 
          ) 
        ) 
      ); 

    //Yes - this is ugly but hopefully readable 
    $url = 'https://'; 
    $url .= Zend_Service_Amazon_S3::S3_ENDPOINT; //e.g s3.amazonaws.com 
    $url .= $this->_getImagePath(); //e.g /mybucket/myFirstCar.jpg 
    $url .='?AWSAccessKeyId=' . $my_aws_key; 
    $url .='&Signature=' . $signature; //signature as returned by below function 
    $url .='&Expires=' . $expirationTime; 

    return $url; 


} 

protected function _generateStringToSign($expires) 
{ 

    $string = "GET\n"; //Methods 
    $string .= "\n"; 
    $string .= "\n"; 
    $string .= "$expires\n"; //Expires 
    $string .= $this->_getImagePath(); 

    return $string; 
}
