<p>WebSocket输入节点。</p>

<p>默认情况下，从WebSocket接收的数据将位于<code>msg.payload</code>中。可以将套接字配置为期望格式正确的JSON字符串，在这种情况下，它将解析JSON并将结果对象作为整个消息发送。</p>

<p>WebSocket输出节点。</p>
|

|

<p>默认情况下，<code>msg.payload</code>将通过WebSocket发送。可以将套接字配置为将整个<code>msg</code>对象编码为JSON字符串，然后通过WebSocket发送。</p>
|

<p>如果到达此节点的消息是从WebSocket In节点开始的，则该消息将发送回触发流程的客户端。否则，消息将广播给所有连接的客户端。</p>

|
<p>如果要广播从“WebSocket输入”节点开始的消息，则可以应该删除流中的<code>msg._session</code>属性。</p>
