        def temp
         try {
           def ret = null
           def http = new HTTPBuilder("http://192.168.1.10:8080/Pay-0.1/main/msgPicTemp")
           http.parser.'text/html' = http.parser.'text/plain'
           http.request(Method.GET, ContentType.TEXT) {
               uri.query = [ appKey:appKey, userName:userName,tempType:tempType]
               headers.'User-Agent' = 'Mozilla/5.0 Ubuntu/8.10 Firefox/3.0.4'
               response.success = { resp,reader -> println resp.status


            println reader.text
                temp=reader.text//i got error here,how to assign this to one variable and pass it to controller
                 }
               response.failure = { resp -> println "Unexpected error: ${resp.status} : ${resp.statusLine.reasonPhrase}" }
           }

          return temp
       } catch (groovyx.net.http.HttpResponseException ex) {
           ex.printStackTrace()
           return null
       } catch (java.net.ConnectException ex) {
           ex.printStackTrace()
           return null
       }
   }

 <link rel="stylesheet" href="/Pay-0.1/static/css/bootstrap.css" type="text/css">

I believe the issue is with your println reader.text. Reading from the stream closes the stream. So your next line, to set the variable isn't going to work. Remove the println reader.text and see if you still have the issue
