<p>在JSON字符串及其JavaScript對象表示形式之間相互轉換</p>
<h3>輸入</h3>
<dl class="message-properties">
<dt>payload<span class="property-type">object | 字符串</span></dt>
<dd>JavaScript對象或JSON字符串</dd>
<dt>schema<span class="property-type">object</span></dt>
<dd>可選的JSON Schema對象用于驗證有效負載在將<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>如果輸入是JSON字符串它將嘗試將其解析爲JavaScript對象</li>
<li>如果輸入是JavaScript對象它將創建一個JSON字符串並可以選擇對此JSON字符串進行整形</li>
</ul>
</dd>
<dt>schemaError<span class="property-type">數組</span></dt>
<dd>如果JSON模式驗證失敗則catch節點將具有包含錯誤數組的<code>schemaError</code></dd>
</dl>
<h3>詳細</h3>
<p>默認的轉換目標是<code>msg.payload</code></p>
<p>您可以將其設置爲僅執行特定的轉換而不是自動選擇雙向轉換例如即使對<code>HTTP In</code>content-type使JSONJavaScript</p>
<p>如果指定了轉換爲JSON字符串則不會對收到的字符串進行進一步的檢查也就是說即使指定了格式化選項它也不會檢查字符串是否正確爲JSON或對JSON執行整形</p>
<p>有關JSON模式的更多詳細信息請查閱<a href="http://json-schema.org/latest/json-schema-validation.html">規範</a>.</p>
