Sample 351: In-line script mediation with JavaScript
Objective: Introduction to in-line script mediation
Prerequisites:
- Start the Synapse configuration numbered 351: i.e.
wso2esb-samples.sh -sn 351
- Start the Axis2 server and deploy the
SimpleStockQuoteService
if not already done.
<definitions xmlns="http://ws.apache.org/ns/synapse"> <in> <!-- transform the custom quote request into a standard quote requst expected by the service --> <script language="js"><![CDATA[ var symbol = mc.getPayloadXML()..*::Code.toString(); mc.setPayloadXML( <m:getQuote xmlns:m="http://services.samples/xsd"> <m:request> <m:symbol>{symbol}</m:symbol> </m:request> </m:getQuote>); ]]></script> <send> <endpoint> <address uri="http://localhost:9000/services/SimpleStockQuoteService"/> </endpoint> </send> </in> <out> <!-- transform the standard response back into the custom format the client expects --> <script language="js"><![CDATA[ var symbol = mc.getPayloadXML()..*::symbol.toString(); var price = mc.getPayloadXML()..*::last.toString(); mc.setPayloadXML( <m:CheckPriceResponse xmlns:m="http://services.samples/xsd"> <m:Code>{symbol}</m:Code> <m:Price>{price}</m:Price> </m:CheckPriceResponse>); ]]></script> <send/> </out> </definitions>
The functionality of this sample is similar to that of sample 350 and sample 8. It demonstrates how to use in-line scripts in the mediation within the ESB. Use the stock quote client to send a custom quote request as described in sample 350.
