Receiving HTTP POST request in Groovy

I have created a simple server which accepts connection request forms the client and reads the request posted by client. Depends upon some values in the request body I would like to respond with some string. and if the server does not receive any requests from the client it just sent some integer values to the client. The following is the code.

def server = new ServerSocket(2000)
println("Waiting for connection")

String receivedRecord ;
while (true) 

{
  println " Input data "
server.accept() { socket ->
          socket.withStreams { input, output ->
                def w = new BufferedWriter(new OutputStreamWriter(output))

        String message = "Connection was successful"
        println message
 def r = new BufferedReader(new InputStreamReader(input))

 println ("Stream ")

String requestMessage = ""
 while (true)
  { 
        String tempMsg = r.readLine() 
        requestMessage = requestMessage  +   tempMsg
        println (requestMessage)
   }       

      int  i = 0;

while (i <20)
{
    //String requestMessage = r.readLine()

    //println(" Request Received ")
    //println(requestMessage)

    String echo = "EchoRequestMsg"
    String vehicleSync = "EenheidSynchronisatieRequestMsg"

    if(requestMessage != null )
    {

        if(requestMessage.toLowerCase().contains(echo.toLowerCase()))
        {
            println (i)
            println ("Echo Request True ")
            sendMessage("Echo", w)
            println(" Echo Message Sent ")

        }
        else if(requestMessage.toLowerCase().contains(vehicleSync.toLowerCase()))
        {     
            println (i)
            println (" Vehicle Sync True ")       
            sendMessage("VehicleSync", w)
            println(" Vehicle Sync Message Sent ")
        }
        else
        {
            println (i)
            println (" push message ")
            i++;
            sendMessage(i, w)
        }

       }   
      }
     }
    }
   }
def sendMessage(msg, writer) {
    println("Sending: >" + msg + "<")
    writer.writeLine(msg.toString())
    writer.flush();
}

It only receive http Header not the body. I have posted the request thru cURL.

Traced Data from cURL:
