Reading Query Parameters in Enterprise Integrator

Following is how you can read query params from your rest service when using Enterprise Integrator.

There are two ways to read your query params.

1. Assigning value to a property within a URI template. (get-property('uri.var.qtest')).

If you look at the following synapse config I'm assigning the required query param to

<api xmlns="http://ws.apache.org/ns/synapse" name="test" context="/qtest">
   <resource methods="GET" uri-template="/search?q={qtest}" outSequence="" faultSequence="">
      <inSequence>
         <log>
            <property name="QUERY PARAM IS =" expression="get-property('uri.var.qtest')"/>
         </log>
      </inSequence>
   </resource>
</api>

2. Reading as a query params. (get-property('query.param.q'))

By default query params are loaded by the EI it self, so you can directly access them without any extra configurations. Following is how you can do this.

<api xmlns="http://ws.apache.org/ns/synapse" name="test" context="/qtest">
   <resource methods="GET" uri-template="/search?q=*" outSequence="" faultSequence="">
      <inSequence>
         <log>
            <property name="QUERY PARAM IS =" expression="get-property('query.param.q')"/>
         </log>
      </inSequence>
   </resource>
</api>
