Question

I\'m trying to do an OAuth2 user-credentials post to an OAuth2 service using the Grails RestBuilder plugin.

If I try to specify the post body as a map, I get an erro

Answer 1

I found out some very easy to perform such type of action

//Get
 public static RestResponse getService(String url) {
  RestResponse rResponse = new RestBuilder(proxy:["localhost":8080]).get(Constants.URL+"methodName")
  return rResponse
 }

 //POST : Send complete request as a JSONObject
 public static RestResponse postService(String url,def jsonObj) {
   RestResponse rResponse = new RestBuilder(proxy:["localhost":8080]).post(url) {
   contentType "application/json"
   json {  jsonRequest = jsonObj  }
  }
  return rResponse
 }

Method 1 :

def resp = RestUtils.getService(Constants.URL+"methodName")?.json
render resp as JSON

Method 2 :

JSONObject jsonObject = new JSONObject()
jsonObject.put("params1", params.paramOne)
jsonObject.put("params2", params.paramTwo)
def resp = RestUtils.postService(Constants.URL+"methodName", jsonObject)?.json
render resp as JSON
