<Get> request to the issue from Scriptrunner functions

Saida

Good day, 

I need to write a GET request to JIRA from a listener / a post-function. 

I have tried some code snippets found here, but they all dont work for me. Running from the Script Console, 

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.nio.charset.StandardCharsets;
import org.apache.log4j.Logger;

def log = Logger.getLogger("com.onresolve.jira.groovy");

 //String targetURL = "https://jiratest:8443/rest/api/2/issue/SD-233373?expand=changelog&fields="""; //?expand=changelog&fields=%22%22
String targetURL = 'https://jiratest:8443/rest/api/2/issue/SD-233373'
try {
 URL restServiceURL = new URL(targetURL);
 String username = "username"
 String password = "password"
 HttpURLConnection httpConnection = (HttpURLConnection) restServiceURL.openConnection();
 httpConnection.setRequestMethod("GET");
 httpConnection.setRequestProperty("Accept", "application/json");
 String encoded = Base64.getEncoder().encodeToString((username+":"+password).getBytes(StandardCharsets.UTF_8)); 
 httpConnection.setRequestProperty("Authorization", "Basic " + encoded);

 if (httpConnection.getResponseCode() != 200) {
 throw new RuntimeException("HTTP GET Request Failed with Error code : "
 + httpConnection.getResponseCode());
 }

 BufferedReader responseBuffer = new BufferedReader(new InputStreamReader(
 (httpConnection.getInputStream())));

 String output;
 log.debug("Output: \n");

 while ((output = responseBuffer.readLine()) != null) {
 return output;
 }

 httpConnection.disconnect();

 } catch (MalformedURLException e) {

 e.printStackTrace();

 } catch (IOException e) {

 e.printStackTrace();

 }

The code returns me 

 

 

Error

HTTP GET Request Failed with Error code : 403

java.lang.RuntimeException: HTTP GET Request Failed with Error code : 403 at Script707.run(Script707.groovy:26)

The script should be like this:

import groovyx.net.http.HTTPBuilder
import net.sf.json.JSONArray
import org.apache.http.HttpRequest;

import org.apache.http.protocol.HttpContext;
import org.apache.http.HttpRequestInterceptor;

def JIRA_API_URL = "https://yourjiradomain"

def jira = new HTTPBuilder(JIRA_API_URL);
jira.client.addRequestInterceptor(new HttpRequestInterceptor() {
void process(HttpRequest httpRequest, HttpContext httpContext) {
httpRequest.addHeader('Authorization', 'Basic ' + 'username:password'.bytes.encodeBase64().toString())
}
})

def resp = jira.get(path: '/rest/api/2/issue/MAV-2', query : [expand:'changelog', fields: '""'])
