Amazon S3 PHP'de İmzalı URL

Question

Bu, imzalı bir Amazon S3 URL'sini döndürmek için eski bir WP eklentisinden çıkarılmış işlevdir, ancak işe yaramayacağım! Ben döndürür imzalı URL'yi ziyaret ettiğinizde, bu alın:

The request signature we calculated does not match the signature you provided. Check your key and signing method.

function s3Url($text) { 
    $AWS_S3_KEY = 'KEY'; 
    $AWS_S3_SECRET = 'SECRET'; 
    $tag_pattern = '/(\[S3 bucket\=(.*?)\ text\=(.*?)\](.*?)\[\/S3\])/i'; 

    define("AWS_S3_KEY", $AWS_S3_KEY); // replace this with your AWS S3 key 
    define("AWS_S3_SECRET", $AWS_S3_SECRET); // replace this with your secret key. 
    $expires = time()+get_option('expire_seconds'); 

    if (preg_match_all ($tag_pattern, $text, $matches)) { 

     for ($m=0; $m<count($matches[0]); $m++) { 
      $bucket = $matches[2][$m]; 
      $link_text = $matches[3][$m]; 
      $resource = $matches[4][$m]; 

      $string_to_sign = "GET\n\n\n$expires\n/".str_replace(".s3.amazonaws.com","",$bucket)."/$resource"; 

      //$string_to_sign = "GET\n\n\n{$expires}\n/{$bucket}/{$resource}"; 
      $signature = urlencode(base64_encode((hash_hmac("sha1", utf8_encode($string_to_sign), AWS_S3_SECRET, TRUE)))); 

      $authentication_params = "AWSAccessKeyId=".AWS_S3_KEY; 
      $authentication_params.= "&Expires={$expires}"; 
      $authentication_params.= "&Signature={$signature}"; 

      $tag_pattern_match = "/(\[S3 bucket\=(.*?)\ text\={$link_text}\]{$resource}\[\/S3\])/i"; 

      if(strlen($link_text) == 0) 
      { 
       $link = "http://{$bucket}/{$resource}?{$authentication_params}"; 
      } 
      else 
      { 
       $link = "<a href='http://{$bucket}/{$resource}?{$authentication_params}'>{$link_text}</a>"; 
      } 

      $text = preg_replace($tag_pattern_match,$link,$text); 
     } 
    } 

    return $text; 
}

Amazon AWS PHP SDK sağlanan örnek: sdk-latest\sdk-1.3.5\sdk-1.3.5\_samples\cli-s3_get_urls_for_uploads.php aşağıdaki kodla oldukça iyi çalışıyor:

 /* Execute our queue of batched requests. This may take a few seconds to a 
     few minutes depending on the size of the files and how fast your upload 
     speeds are. */ 
    $file_upload_response = $s3->batch()->send(); 

    /* Since a batch of requests will return multiple responses, let's 
     make sure they ALL came back successfully using `areOK()` (singular 
     responses use `isOK()`). */ 
    if ($file_upload_response->areOK()) 
    { 
     // Loop through the individual filenames 
     foreach ($individual_filenames as $filename) 
     { 
      /* Display a URL for each of the files we uploaded. Since uploads default to 
       private (you can choose to override this setting when uploading), we'll 
       pre-authenticate the file URL for the next 5 minutes. */ 
      echo $s3->get_object_url($bucket, $filename, '5 minutes') . PHP_EOL . PHP_EOL; 
     } 
    }
