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";

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

उदाहरण Amazon AWS PHP SDK में उपलब्ध कराई गई: sdk-latest\sdk-1.3.5\sdk-1.3.5\_samples\cli-s3_get_urls_for_uploads.php निम्नलिखित कोड काफी अच्छी तरह से काम करता है:

 /* 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; 
     } 
    }
