Creating a role

import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Scanner;
import org.json.JSONObject;
import static org.example.FetchToken.getToken;

public class CreateRole {

   public static void main(String[] args) {
       try {
           String url = "http://your-openiam-instance/webconsole/rest/api/roles/save";

           // [1] Create the JSON payload
           JSONObject targetObject = new JSONObject();
           targetObject.put("mdTypeId", "ACCESS_ROLE");
           targetObject.put("name", "role-name");
           targetObject.put("managerSysId", "0");

           JSONObject payload = new JSONObject();
           payload.put("targetObject", targetObject);

           // [2] Create the connection
           URL obj = new URL(url);
           HttpURLConnection con = (HttpURLConnection) obj.openConnection();
           con.setRequestMethod("POST");
           con.setRequestProperty("Content-Type", "application/json");
           con.setRequestProperty("Authorization", "Bearer " + getToken());
           con.setDoOutput(true);

           // [3] Send the request
           OutputStream os = con.getOutputStream();
           os.write(payload.toString().getBytes("UTF-8"));
           os.close();

           // [4] Read the response
           Scanner in = new Scanner(con.getInputStream());
           StringBuilder response = new StringBuilder();
           while (in.hasNext()) {
               response.append(in.nextLine());
           }
           in.close();

           // [5] Print the response
           System.out.println(response.toString());

       } catch (Exception e) {
           e.printStackTrace();
       }
   }
}

Example output is given below.

Deleting a role

Note: role ID can be found under primaryKey in the output for CreateRole.java, e.g. – primaryKey":"ff8080819133afc9019133cca26f000c". Replace the roleid in the URL with this value.

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import static org.example.FetchToken.getToken;

public class DeleteRole {

   public static void main(String[] args) {
       try {
           String url = "http://your-openiam-instance/webconsole/rest/api/roles/roleid";

           // [1] Create the connection
           URL obj = new URL(url);
           HttpURLConnection con = (HttpURLConnection) obj.openConnection();
           con.setRequestMethod("DELETE");
           con.setRequestProperty("Content-Type", "application/json");
           con.setRequestProperty("Authorization", "Bearer " + getToken());

           // [2] Read in the response
           int responseCode = con.getResponseCode();
           BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
           String inputLine;
           StringBuilder response = new StringBuilder();
           while ((inputLine = in.readLine()) != null) {
               response.append(inputLine);
           }
           in.close();

           // [3] Print the response
           System.out.println(response.toString());

       } catch (Exception e) {
           e.printStackTrace();
       }
   }
}

Output example is given below.

{"primaryKey":null,"status":200,"errorList":null,"redirectURL":"roles","successToken":{"message":"ROLE_DELETE","params":null},"successMessage":"Role was deleted successfully","contextValues":null,"stackTrace":null,"possibleErrors":null,"error":false}
