using HTTPBuilder in Groovy

Hi I am trying to use HTTPBuilder to access https since URL failed on connecting to https. Looks like I need to use following in order to enable the HTTPBuilder class,

 But I am getting following error complaining about @Grab, I suppose @Grab is not supported

Thanks

Dong

Hi Dong

@Grab should be definitely supported.
I tested just that two line code, you posted. And It works for me... although the first line only does not work alone. 

I guess the problem is somewhere else. If you really think there is a problem with Groovy implementation in IJC and willing to share the script, just drop me a mail.

Cheers

following comes straight from http://groovy.codehaus.org/HTTP+Builder , i paste in script window in ijc 5.11.3.1, it has been running for 3 minutes, and still going ....

 

@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.5.0-RC2' )
import groovyx.net.http.*
import static groovyx.net.http.ContentType.*
import static groovyx.net.http.Method.*

def http = new HTTPBuilder( 'http://ajax.googleapis.com' )

// perform a GET request, expecting JSON response data
http.request( GET, JSON ) {
  uri.path = '/ajax/services/search/web'
  uri.query = [ v:'1.0', q: 'Calvin and Hobbes' ]

  headers.'User-Agent' = 'Mozilla/5.0 Ubuntu/8.10 Firefox/3.0.4'

  // response handler for a success response code:
  response.success = { resp, json ->
    println resp.statusLine

    // parse the JSON response object:
    json.responseData.results.each {
      println "  ${it.titleNoFormatting} : ${it.visibleUrl}"
    }
  }

  // handler for any failure status code:
  response.failure = { resp ->
    println "Unexpected error: ${resp.statusLine.statusCode} : ${resp.statusLine.reasonPhrase}"
  }
}

after almost 10 minutes, i am getting following error:

Strange, it works for me in different IJC versions. This is the output:

 

Executing Groovy script 'New Script'

Script execution took 2553 ms

which version, man ????

Tested in v5.9.4, v5.11.4 and development trunk. All works.

I susspect that your issue can be caused by a proxy setting. Does Instant JChem have access to the internet?

I did not try it with proxy yet... 

Dong,

I tested it with proxy set up in IJC 5.11.5 this time and it was working. Please ensure that you have access to the Internet - you can see the recent forum posts on welcome screen.

Without the internet connection, I see that java.lang.RuntimeException too, except is took only a second to appear.

Is it possible that it's blocked by a proxy server if RSS feed and forum on welcome screen is accessible?
