Sign验证代码
<p><strong>Notice</strong>: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。</p>

<pre><code class="language-php">$token = 'uniondrug';
$nonce = '94092762BDA12EF580DA1B773738DE5E1';

$data = array($token, $nonce, $timestamp);
sort($data, SORT_STRING);
$sign_orign = implode('',$data);
$sign = sha1($sign_orign);</code></pre>
