Execute POST with form URL encoded params

[MiguelAngel82]

Hi all,

I want to make a POST with URL encoded params and I have followed the guide, but it doesnt work. Executed it from cURL it works as expeted, but transforming it to HTTPBuilder doesn't work.

Code from cURL:

curl -X POST -u "user:pass" https://bitbucket.org/site/oauth2/access_token -d grant_type=client_credentials

Code made with HTTPBuilder:

    String url = 'https://bitbucket.org/'
    HTTPBuilder http = new HTTPBuilder(url)
    authSite.auth.basic 'user', 'pass'
    http.post( path: '/site/oauth2/access_token', body: [grant_type:'client_credentials'],
    	requestContentType: URLENC ) { resp ->
   			println "POST Success: ${resp.statusLine}"
  			assert resp.statusLine.statusCode == 201
    }

With the former code the response is "Bad request" while with cURL the response is as expected.

Is anything missed in the HTTPBuilder configuration?

Thanks in advance!

Regards,
Miguel.
