title: WireMock: How configure a JSON to show request headers in the response
body: <p>I need your help to configure a mapping json file in WireMock. I have two problems to begin:
  1- I need to see in the response the same headers that I sent by GET request. I only can show one header. How I should add a second headers in the body response to show it? 
  2- Does it possible add in the body some other values or text as well? </p>
  
  <p>I have this json:</p>
  
  <pre><code>{    
  "request": 
      {      
      "urlPath": "/templated"    
      },    
      "response": 
          {        
          "body": "{{request.headers.msisdn.[0]}}",        
          "transformers": ["response-template"]    
          }       
  }
  </code></pre>
  
  <p>I run this: </p>
  
  <p>curl -X GET \
  -H "" \
  -H "msisdn: 881163662742" \
  -H "client: 1c30cd57-183c-491d-a666-056fed10060a" \
  <a href="http://localhost:8000/templated" rel="nofollow noreferrer">http://localhost:8000/templated</a></p>
  
  <p>I get this:
  881163662742</p>
  
  <p>I want this as response:</p>
  
  <p>For a second header in the body response, i tried this json without success:</p>
  
  <pre><code>{    
  "request": 
      {      
      "urlPath": "/templated"    
      },    
      "response": 
          {        
          "body": "{{request.headers.msisdn.[0]},{request.headers.client.[0]}}",        
          "transformers": ["response-template"]    
          }       
  }
  </code></pre>
  
  <p>If you know some website with examples about it, I'll appreciate.</p>
  
  <p>Thanks!</p>
