REST with OSB GET method

Simple way to invoke REST with GET method


1. Create a Business Service with URL and use Route action.





2. How to pass parameters?
a. Add insert action -
 


b.Xpath -


./ctx:transport/ctx:request




c. You can create parameters like this
<http:query-parameters>
<http:parameter name="startValue" value="{$startVal}" />
<http:parameter name="end" value="{$endVal}" />
</http:query-parameters>




where startVal /EndVal is a variable created and passed input from Request. Otherwise you can directly use the value instead of Variable.
If there are multiple parameters, include all the parameters here
