The script mediator

We can use different scripting languages to process the payload and get some information or make a transformation, such as JavaScript, Groovy, and Ruby.

Inline script syntax is as follows:

<script language="js">
  <![CDATA[
       //script code
   ]]>
<script/>

This is the registry script syntax:

<script key="path/to/script" language="(js | groovy | rb)" [function="nameOfTheFunction"]>
     [<include key="string"/>]
</script>  

The following is a list of the available methods:

• getPayloadXML(): Returns the current XML payload.
• setPayloadXML(payload): Set the body with the content of the payload parameter.
• addHeader(mustUnderstand, content): Add a new SOAP header.
• getEnvelopeXML(): Return the full payload.
• setTo(reference): Set the value of the To header (receiver).
• setFaultTo(reference): Set the value to the FaultTo header.
• setFrom(reference): Set the value to the From header (sender).
• setReplyTo(reference): Set the value to the ReplyTo header.
• getPayloadJSON(): Return the current JSON payload.
• setPayloadJSON(payload): Set the body with the content of the payload parameter.
• getProperty(name): Get the value of a property.
• setProperty(key, value): Create or update the content of the property from the first param with the value of the second param.

For example, this is the script to print the current value of a property and set the new value:

<script language="js">
   <![CDATA[
     var property = mc.getProperty("static");
     print("property: " + property);
     mc.setProperty("static", "newValue");
   ]]>
</script>
