[Groovy] Choose response from Onrequest script

Hello,

I have a problem with my groovy script. I try to make an OnRequest script on my mockservices.

This script must check some parameters on the receive mockRequest and afterthat select the operation and the response to send. I want to write this script to prevent from code repeating in each operation.

For the moment with my onRequest script, i know the operation name and the response name (the one i want to choose) but i don't know how to set the response that the mockService will send finally.

Can you help me to dispatch or set the response ?

Thank's

Below on example of my script:

// Def variable
def opeList = mockRunner.mockService.getMockOperationList()
def request = mockRequest.getRequestContent()
def operation = ""

// Set a variable with the operation name i want
opeList.eachWithIndex() { 
 key, value -> 
 if (  request =~ /\b${key.name}\b/ ){ 
  operation = "${key.name}"
  //log.info "operation = " + operation
  }
}
switch ( operation ) {
 case "operation1" : if(param1='john doe') {return response1} //I want to send response1 if a variable on the request is john doe but i don't know how to say "choose response1"
                                  if(param1='jerry') {return response2}
                                  break
       case "operation2": if (param1='john doe') { return response1}
// ....
