Sign验证代码

Notice:由药联提供双方校验的token值，对方根据sign生成机制生成sign，和请求方中的sign进行对比。

PHP

$token = 'uniondrug';
$nonce =  '94092762BDA12EF580DA1B773738DE5E1';
$timestamp = '1507602046';
$data = array($token, $nonce, $timestamp);
sort($data, SORT_STRING);
$sign_orign = implode('',$data);
$sign = sha1($sign_orign);
