<h1>具体变更的地方：</h1>
<ul>
<li>您无需再指定<code>roottype</code>，解析器会自动解析json数据的格式</li>
<li><code>path</code>结点下，您无需再指定<code>type</code>，解析器会自动解析json数据的格式</li>
<li><code>model</code>结点下，对于每一个对象，无需在对象内指定<code>&quot;type&quot;:&quot;string&quot;</code>或<code>type:&quot;number&quot;</code>等等，直接指定<code>&quot;node&quot;:xxx</code>即可；此外，对象内的<code>type</code>将与<code>value</code>配合使用，以前版本的规则内没有<code>value</code>这一项，您在变更时，可能需要将<code>&quot;node&quot;</code>改为<code>&quot;value&quot;</code>。如果是要指定默认值，直接用<code>&quot;default&quot;:xxx</code>指定即可。</li>
<li>您可能会注意到，上面新版的解析规则少了
<pre><code>{
&quot;node&quot;:&quot;(?&lt;=[(（])[^（）()]*(?=[)）])&quot;,
&quot;type&quot;:&quot;regex&quot;
}</code></pre>
<p>这是因为正则表达式的功能似乎在新版本遇到了一些bug，我正在排查此问题，如果排查成功，我将在2.7.4版本修正此问题，并更新本文档。</p></li>
