web services - Amazon S3 Signed URL in PHP -


this function pulled out of old wp plugin returning signed amazon s3 url, can't work! when visit signed url returns, this:

the request signature calculated not match signature provided. check key , 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 aws s3 key     define("aws_s3_secret", $aws_s3_secret); // replace secret key.     $expires = time()+get_option('expire_seconds');      if (preg_match_all ($tag_pattern, $text, $matches)) {          ($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; }

the example provided in amazon aws php sdk: sdk-latest\sdk-1.3.5\sdk-1.3.5\_samples\cli-s3_get_urls_for_uploads.php following code works quite well:

        /* execute our queue of batched requests. may take few seconds        few minutes depending on size of files , how fast upload        speeds are. */     $file_upload_response = $s3->batch()->send();      /* since batch of requests return multiple responses, let's        make sure came using `areok()` (singular        responses use `isok()`). */     if ($file_upload_response->areok())     {         // loop through individual filenames         foreach ($individual_filenames $filename)         {             /* display url each of files uploaded. since uploads default                private (you can choose override setting when uploading), we'll                pre-authenticate file url next 5 minutes. */             echo $s3->get_object_url($bucket, $filename, '5 minutes') . php_eol . php_eol;         }     }
