<p>在JSON字符串及其JavaScript对象表示形式之间相互转换</p>
<h3>输入</h3>
<dl class="message-properties">
<dt>payload<span class="property-type">object | 字符串</span></dt>
<dd>JavaScript对象或JSON字符串</dd>
<dt>schema<span class="property-type">object</span></dt>
<dd>可选的JSON Schema对象用于验证有效负载在将<code>msg</code></dd>
</dl>
<h3>Outputs</h3>
<dl class="message-properties">
<dt>payload<span class="property-type">object | 字符串</span></dt>
<dd>
<ul>
<li>如果输入是JSON字符串它将尝试将其解析为JavaScript对象</li>
<li>如果输入是JavaScript对象它将创建一个JSON字符串并可以选择对此JSON字符串进行整形</li>
</ul>
</dd>
<dt>schemaError<span class="property-type">数组</span></dt>
<dd>如果JSON模式验证失败则catch节点将具有包含错误数组的<code>schemaError</code></dd>
</dl>
<h3>详细</h3>
<p>默认的转换目标是<code>msg.payload</code></p>
<p>您可以将其设置为仅执行特定的转换而不是自动选择双向转换例如即使对<code>HTTP In</code>content-type使JSONJavaScript</p>
<p>如果指定了转换为JSON字符串则不会对收到的字符串进行进一步的检查也就是说即使指定了格式化选项它也不会检查字符串是否正确为JSON或对JSON执行整形</p>
<p>有关JSON模式的更多详细信息请查阅<a href="http://json-schema.org/latest/json-schema-validation.html">规范</a>.</p>
