<pre><code>sign = sha256( appId + appSecret + timestamp)</code></pre>
<p>用服务商分配的 appId、服务商分配的 appSecret，当前时间毫秒数 timestamp，按上述顺序拼接成字符串，再进行 sha256 哈希得到。如下：</p>
<pre><code class="language-java">String appId = &quot;xyzxy2121zxyz&quot;；
String timestamp = &quot;1555378976238&quot;；
String appSecret = &quot;efcefcef1121cefcefc1212121&quot;；
String str = appId + appSecret + timestamp；
String sign = sha256(str)；</code></pre>
