Sometimes you need a little web server

Here’s a simple jetty server using a short Groovy script:

@Grab(group='org.mortbay.jetty', module='jetty-embedded', version='6.1.14')

import org.mortbay.jetty.*
import org.mortbay.jetty.servlet.*
import groovy.servlet.*
import javax.servlet.*
import javax.servlet.http.*

class MyServlet extends HttpServlet  {
  void doPost(HttpServletRequest request, HttpServletResponse response) {
    println "--- Received ${new Date()}n" + request.getParameter('data')
  }
}

def server = new Server(8888)
def root = new Context(server, "/", Context.SESSIONS)
root.setResourceBase(".")
root.addServlet(new ServletHolder(new MyServlet()), "/")
server.start()

Running the script with groovy AtlasServer.groovy will accept HTTP POSTs at the designated port (8888) and dump posted data to the screen.  For example:

$ curl -X POST -d "data=Hello world!" http://localhost:8888/

should dump “Hello world!” to the screen.  Press Ctrl+C to abort the server.
