User logs in to external system and implicitly gains access to Joget Workflow without being prompted to login again.

Using JSON API

  • Using '/web/json/directory/user/sso' JSON API.
  • You are allowed to call this method using JSON API Authentication or 
  • Directly passes the username and password with "username" and "password" parameters respectively shown in following example.
Code Block
languagejs
<script>
    $(document).ready(function(){
		$.ajax({
            type: "POST",
            url: 'http://localhost:8080/jw/web/json/directory/user/sso?callback=callbackFunction',
            data: {
                username: 'admin',
                password: 'admin'
            },
            success: function(res) {
                console.log("username (" + res.username + ") is " + ((res.isAdmin !== undefined && res.isAdmin === "true")?"admin":"not an admin"));
            },
            dataType: "json"
        });
    });
</script>

Using Basic Http Authentication with JSON API

  • Since V4, Joget Workflow is supported Basic HTTP Authentication in JSON API authentication, you can passing the credentials in the header.
  • Example: Assuming the username and password required is "user1" and "password1" respectively, we can set the Basic Auth header to the JSON API using following jQuery script.
Code Block
languagejs
<script>
    $(document).ready(function(){
		$.ajax({
            type: "POST",
            url: 'http://localhost:8080/jw/web/json/directory/user/sso',
            beforeSend: function (xhr) {
                xhr.setRequestHeader ("Authorization", "Basic dXNlcjE6cGFzc3dvcmQx");
            },
            success: function(res) {
                console.log("username (" + res.username + ") is " + ((res.isAdmin !== undefined && res.isAdmin === "true")?"admin":"not an admin"));
            },
            dataType: "json"
        });
    });
</script>

Using Javascript API

  • Includes the jQuery & util.js libraries. 

  • Using the AssignmentManager.login method for SSO.

  • Perform actions in callback of successful login.
Code Block
langjavascript
<script type="text/javascript" src="http://localhost:8080/jw/js/jquery/jquery-1.9.1.min.js"></script>
<script type="text/javascript" src="http://localhost:8080/jw/js/json/util.js" ></script>

<script type="text/javascript" >
$(document).ready(function(){
    var loginCallback = {
        success : function(response){
            if(response.username != "roleAnonymous"){
                alert("login successfully");
            }else{
                alert("login fail");
            }
        }
    };
    AssignmentManager.login('http://localhost:8080/jw', 'admin', 'admin', loginCallback);
});
</script>

Login an User Programmatically


 

Code Block
import org.joget.apps.workflow.security.WorkflowUserDetails;
import org.joget.directory.model.service.DirectoryManager;
import org.joget.workflow.model.service.WorkflowUserManager;
import org.joget.apps.app.service.AppUtil;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;

import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletRequest;
import org.springframework.security.web.savedrequest.HttpSessionRequestCache;
import org.springframework.security.web.savedrequest.SavedRequest;
 
//Get service beans
DirectoryManager dm = (DirectoryManager) AppUtil.getApplicationContext().getBean("directoryManager");
WorkflowUserManager workflowUserManager = (WorkflowUserManager) AppUtil.getApplicationContext().getBean("workflowUserManager");
 
//Login as "clark"
String username = "clark"; 
User user = dm.getUserByUsername(username);

if (user != null) {
    WorkflowUserDetails userDetail = new WorkflowUserDetails(user);
 
    //Generate an authentication token without a password
    UsernamePasswordAuthenticationToken auth = new UsernamePasswordAuthenticationToken(userDetail.getUsername(), "", userDetail.getAuthorities());
    auth.setDetails(userDetail);
    //Login the user
    SecurityContextHolder.getContext().setAuthentication(auth);
    workflowUserManager.setCurrentThreadUser(user.getUsername());

    // generate new session to avoid session fixation vulnerability
    HttpServletRequest httpRequest = WorkflowUtil.getHttpServletRequest();
    HttpSession session = httpRequest.getSession(false);
    if (session != null) {
        SavedRequest savedRequest = (SavedRequest) session.getAttribute("SPRING_SECURITY_SAVED_REQUEST_KEY");
        session.invalidate();
        session = httpRequest.getSession(true);
        if (savedRequest != null) {
            session.setAttribute("SPRING_SECURITY_SAVED_REQUEST_KEY", savedRequest);
        }
    }
}

Please note that if you are adding these code in a filter, you will need to store the SecurityContext to session.

Code Block
//Store SecurityContext to session to avoid spring security to clean it.
session.setAttribute("SPRING_SECURITY_CONTEXT", SecurityContextHolder.getContext());
