Totvs Fluig - Customization - Call in REST service in beforeSendData event

Question

Does anyone know how to make a call to a REST service within the beforeSendData event, follow below my code (not functional):

My goal is to run a call on a REST service of the fluig itself in order to get the detail of a request (process instance).

I tried using the standard jQuery call but it didn’t work, this script runs on the server side.

function beforeSendData(customFields, customFacts) {
      log.info("****************teste");      
      customFields[0] = "1";
      customFacts[0] = 10.53;      
      var processInstanceId = getValue("WKNumProces"); 
      var taskUserId = getValue("WKUser");     
      log.info("****************teste");
//Tentei usar esta API mas não funciona
//Tentei usar jQuery mas também não funcionou.
      WCMAPI.Read({
        type: "POST",
        url: WCMAPI.getServerURL() + '/ecm/api/rest/ecm/workflowView/findDetailsMyRequests?processInstanceId=' + processInstanceId + "&taskUserId=" + taskUserId,
        async: false,
        success: function funcao(data) {
            log.info(txt);
            var data = jQuery.parseJSON(txt);        
        },
        error: function (msg){
            log.info("****Não funcionou********");
        }
    });     
}

I’ve turned your comment into an answer, so the question doesn’t go unanswered, and it can help other people. Take it as correct, if applicable. I made the corrections in the variable declarations, you do not need to put var at all, just at the beginning, separating with comma.

var url = "google.com",
get = new org.apache.commons.httpclient.methods.GetMethod(url),
client = new org.apache.commons.httpclient.HttpClient(),
br = new java.io.BufferedReader(newjava.io.InputStreamReader(get.getResponseBodyAsStream())),
response = "",
line = br.readLine();
 while(line != null)
 {
   response = response + line; 
   line = br.readLine()
 } 

log.info(response); 
get.releaseConnection();
