Это функция, вытащенная из старого плагина WP для возврата подписанного URL-адреса Amazon S3, но я не могу заставить его работать! Когда я посещаю подписанный URL-адрес, он возвращается, я получаю следующее:
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; }
Пример, представленный в SDK SDK SDK для Amazon : sdk-latest\sdk-1.3.5\sdk-1.3.5\_samples\cli-s3_get_urls_for_uploads.php следующий код работает достаточно хорошо:
/* 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; } }
