building async httpbuilder similar to httpbuilder

Question

Might be the wrong place to post this but I have been messing around with async http builders trying to get basic cypher queries to work. It works with Http Builders but can't get it to work with the async version.

   @Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.6' )
    @Grab(group='net.sf.json-lib', module='json-lib', version='2.4', classifier='jdk15' )

    import groovyx.net.http.*
    import static groovyx.net.http.ContentType.*
    import static groovyx.net.http.Method.*

    def query(statement, params,success, error) {
    def http = new HTTPBuilder( 'http://localhost:7474' )
    http.request( POST, JSON ) {
    uri.path = '/db/data/cypher/'
    headers.'X-Stream' = 'true'
    requestContentType = JSON
    body =  [ query : statement , params : params ?: [:] ]

     // uri.query = [ param : 'value' ]

     response.success = { resp, json ->
       if (success) success(json)
       else {
        println "Status ${resp.statusLine} Columns ${json.columns}\nData: ${json.data}"
       }
     }

     response.failure = { resp, message ->
           def result=[status:resp.statusLine.statusCode,statusText:resp.statusLine.reasonPhrase]
           result.headers = resp.headers.collect { h -> [ (h.name) : h.value ] }
           result.message = message
       if (error) {
                 error(result)
       } else {
        println "Status: ${result.status} : ${result.statusText} "
        println 'Headers: ${result.headers}'
        println 'Message: ${result.message}'
       }
     }
    }
   }

query("MATCH n RETURN n;",[],{ println "Success: ${it}" },{ println "Error: ${it}" })

However I have tried this with the AsyncHttpBuilder . Couldn't get it to work. Now I am trying a simple thing and have been unable to get it to give anytype of useful result.

@Test
public void testQueue()
{
    def http = new AsyncHTTPBuilder( poolSize : 1 ,
            uri : 'http://localhost:7474/db/data/cypher' )
    def responses = []
    responses << http.post(query : [q:  "MATCH n RETURN n;"]) {return it}


    if (!responses.every{it.done})
    {
        println 'waiting...'
        Thread.sleep(2000)
    }
    responses.each {
        println(it)
    }
    http.shutdown()
} 

Any thoughts? Thanks!

you need to pass in the cypher query in the request's body and not as query param. See https://gist.github.com/sarmbruster/8114445 for a working example
