<h3>详细</h3>
<p>通过使用特定的有效荷载注入节点可以启动流默认有效荷载是当前时间的时间戳以毫秒为单位自1970年1月1日起</p>
<p>该节点还支持注入字符串数字布尔值JavaScript对象或流/全局上下文值</p>
<p>默认情况下节点可以通过在编辑器中单击节点按钮来手动触发同时也可以被设置为定期或按计划注入</p>
<p>另一个可选的设置是在每次启动流时注入一次</p>

<p>当另一个节点完成对消息的处理时触发流</p>
<h3>详细</h3>
<p>如果一个节点通知运行时它已完成消息的处理该节点可用于触发第二个流</p>
<p>这个节点可以与没有输出端口的节点一起使用例如在使用电子邮件发送节点来发送邮件后触发一个流</p>
<p>此节点只能被设置为处理流中某个所选节点的事件与Catch节点不同您不能指定所有节点模式并以流中的所有节点为目标</p>
<p>并非所有节点都会触发此事件这取决于它们是否支持于Node-RED 1.0中引入的此功能</p>

<p>输入消息在名为<code>msg</code>JavaScript</p>
<p>通常<code>msg</code><code>msg.payload</code></p>
<p>该函数一般会返回一个消息对象或多个消息对象但也可以为了停止流而什么都不返回</p>
<h3>详细</h3>
<p>请参见<a target="_blank" href="http://nodered.org/docs/writing-functions.html">在线文档</a></p>
<h4>传送消息</h4>
<p>要将消息传递到流中的下一个节点请返回消息或调用<code>node.send(messages)</code></p>
<p>它将返回/send:</p>
<ul>
<li>单个消息对象 - 传递给连接到第一个输出的节点</li>
<li>消息对象数组传递给连接到相应输出的节点</li>
</ul>
<p>如果数组元素是数组则将多个消息发送到相应的输出</p>
<p>无论return方法是单个值还是数组元素如果返回值为null则不会发送任何消息</p>
<h4>日志输出和错误处理</h4>
<p>使用以下功能输出日志信息和输出错误</p>
<ul>
<li><code>node.log("Log message")</code></li>
<li><code>node.warn("Warning")</code></li>
<li><code>node.error("Error")</code></li>
</ul>

<p>使用catch节点可以进行错误处理 要由catch节点处理请将<code>msg</code><code>node.error</code></p>
<pre>node.error("Error",msg);</pre>
<h4>访问节点信息</h4>
<p>您可以使用以下属性来在代码中引用节点ID和名称</p>
<ul>
<li><code>node.id</code> - ID</li>
<li><code>node.name</code> - </li>
</ul>
<h4>使用环境变量</h4>
<p>环境变量可以通过<code>env.get("MY_ENV_VAR")</code>访</p>

<p>将消息序列合并为一条消息.</p>
<p>共有三种模式</p>
<dl>
<dt>自动模式</dt>
<dd><b>split</b></dd>
<dt>手动模式</dt>
<dd>手动地以各种方式合并消息序列</dd>
<dt>列聚合模式</dt>
<dd>对消息列中的所有消息应用表达式以将其简化为单个消息</dd>
</dl>
<h3>输入</h3>
<dl class="message-properties">
<dt class="optional">parts<span class="property-type">object</span></dt>
<dd>使用自动模式时所有的消息都应包含此属性<b>split</b>
<ul>
<li><code>id</code> - </li>
<li><code>index</code> - </li>
<li><code>count</code> - </li>
<li><code>type</code> - -///buffer</li>
<li><code>ch</code> - buffer</li>

<li><code>len</code> - 使</li>
</ul>
</dd>
<dt class="optional">complete</dt>
<dd>如果设置则节点将以其当前状态发送其输出消息</dd>
</dl>
<h3>详细</h3>
<h4>自动模式</h4>
<p>自动模式使用传入消息的<code>parts</code>使<b>split</b></p>
<h4>手动模式</h4>
<p>设置为以手动模式时该节点能以各种不同的方法来处理消息</p>
<ul>
<li><b>字符串</b><b></b>-</li>
<li><b>数组</b> - </li>
<li><b>/值对象</b> - 使</li>
<li><b>merged object</b> - </li>
</ul>
<p>输出消息的其他属性都取自发送结果前的最后一条消息</p>
<p>可以用<i>计数</i></p>
<p>可以用<i>超时</i></p>
<p>如果收到设置了<b>msg.complete</b></p>
<p>如果收到设置了<b>msg.reset</b></p>
<h4>列聚合模式</h4>
<p>选择列聚合模式时将表达式应用于组成消息列的每条消息并使用聚合值组成一条消息</p>
<dl class="message-properties">
<dt>初始值</dt>
<dd>累积值的初始值(<code>$A</code>)</dd>
<dt>聚合表达式</dt>
<dd>序列中的每个消息调用的JSONata表达式结果将作为累加值传递到表达式的下一个调用在表达式中可以使用以下特殊变量
<ul>
<li><code>$A</code>: </li>
<li><code>$I</code>: </li>
<li><code>$N</code>: </li>
</ul>
</dd>
<dt>最终调整式子</dt>
<dd>可选的JSONata表达式在将聚合表达式应用于序列中的所有消息之后应用在表达式中可以使用以下特殊变量
<ul>
<li><code>$A</code>: </li>
<li><code>$N</code>: </li>
</ul>
</dd>
<p>默认情况下按顺序从序列的第一条消息到最后一条消息应用聚合表达式也可以选择以相反的顺序应用聚合表达式</p>
</dl>
<p><b>例子</b>
<ul>
<li><b>聚合表达式</b>: <code>$A+payload</code></li>
<li><b>初始值</b>: <code>0</code></li>
<li><b>最终调整式</b>: <code>$A/$N</code></li>
</ul>
</p>
<h4>储存讯息</h4>
<p>该节点将在内部缓存消息以便跨序列工作运行时设置<code>nodeMessageBufferMaxLength</code></p>

<h3>输出</h3>

<h3>详细</h3>

<p>以字符串或二进制缓冲区的形式读取文件的内容</p>
<h3>输入</h3>
<dl class="message-properties">
<dt class="optional">filename<span class="property-type">字符串</span></dt>

<dd><i>已不推荐使用</i>: <code></code><code>error</code> </dd>

<h3>详细</h3>
<p>文件名应该是绝对路径否则将相对于Node-RED进程的工作目录</p>
<p>在Windows上可能需要使用转义路径分隔符例如<code>\\Users\\myUser</code></p>
<p>可以选择将文本文件拆分为几行每行输出一条消息或者将二进制文件拆分为较小的buffer块-块大小取决于操作系统但通常为64kLinux/Mac或41kWindows</p>
<p>当拆分为多条消息时每条消息将具有<code>parts</code></p>
<p>如果输出格式为字符串则可以从编码列表中指定输入数据的编码</p>
<h4>旧版的错误处理</h4>
<p>在Node-RED 0.17之前如果此节点在读取文件时遇到错误它将发送一条不包含<code>msg.payload</code><code>msg.error</code><code>msg.error</code></p>
<p>应该使用Catch节点来捕获并处理错误</p>
