<h3>签名算法说明</h3>
<pre><code>sign = sha256(appId + appSecret + timestamp)</code></pre>
<p>用服务商分配的 <strong>appId</strong>、服务商分配的 <strong>appSecret</strong>，当前时间毫秒数 <strong>timestamp</strong>，按上述顺序拼接成字符串，再进行 <strong>sha256</strong> 哈希得到。如下：</p>
<pre><code class="language-java">String appId = "xyzxy2121zxyz"；
String timestamp = "1555378976238"；
String appSecret = "efcefcef1121cefcefc1212121"；
String str = appId + appSecret + timestamp；
String sign = sha256(str)；</code></pre>
