|
||
<dd>一个msg对象，其中包含着用于填充模板的信息。</dd>
|

</dl>
|
||
<h3>详细</h3>
|
||
<p>默认情况下使用<i><a href="http://mustache.github.io/mustache.5.html" target="_blank">mustache</a></i>格式。如有需要也可以切换其他格式。</p>
|
||
<p>例如:
|
||
<pre>Hello {{payload.name}}. Today is {{date}}</pre>
|
||
<p>receives a message containing:
|
||
<pre>{
|
||
date: "Monday",
|
||
payload: {
|
||
name: "Fred"
|
||
}
|
||
}</pre>
|
||
<p>输出的消息将会是:
|
||
<pre>Hello Fred. Today is Monday</pre>
|
||
<p>也可以使用流上下文或全局上下文中的属性：<code>{{flow.name}}</code>或者<code>{{global.name}}</code>，或者为了持久储存<code>store</code>，可以使用<code>{{flow[store].name}}</code>或<code>{{global[store].name}}</code>。
|
||
<p><b>注意：</b>默认情况下，<i>mustache</i>将在其替换的值中转义任何非字母数字或HTML实体。为了防止这种情况，请使用<code>{{{triple}}}</code>大括号。
