<script type="text/x-red" data-help-name="delay">
<p>對通過節點的消息進行延遲發送或限制。</p>
<h3>輸入</h3>
<dl class="message-properties">
<dt class="optional">delay <span class="property-type">數值</span></dt>
<dd>設置要應用于消息的延遲(以毫秒爲單位)。僅當節點配置爲允許消息去覆蓋配置的默認延遲間隔時,此選項才適用。</dd>
<dt class="optional">reset</dt>
<dd>如果接收到的消息將此屬性設置爲任何值,則將清空該節點保留的所有的未發送消息。</dd>
<dt class="optional">flush</dt>
<dd>如果接收到的消息的此屬性設置爲任何值,則將立即發送該節點保留的所有未發送消息。</dd>
</dl>
<h3>詳細</h3>
<p>當配置爲延遲發送消息時,延遲間隔可以是一個固定值,一個範圍內的隨機值或爲每個消息動態設置。</p>
<p>當配置爲對消息進行限制時,它們的傳遞將分散在配置的時間段內。狀態顯示隊列中當前的消息數。可以選擇在中間消息到達時丟棄它們。</p>
<p>速率限制可以應用于所有消息,也可以根據<code>msg.topic</code>的值來進行分組。分組時,中間消息將會被自動刪除。在每個時間間隔,節點可以釋放所有主題的最新消息,或釋放下一個主題的最新消息。</p>
