Making an authenticated REST call from within a Jira listener

[SCic]

Hi,

I've written a Jira Java plugin which implements a listener for issue update events.

Once an event occurs, I need to make a REST call to the Jira server, using the current authentication (the user that initiated the issue update).

I know how to make the call to the connected Confluence server, using code similar to this:

String url = "/rest/myrest/1.0/test";

ApplicationLink appLink = applicationLinkService.getPrimaryApplicationLink(ConfluenceApplicationType.class);  

ApplicationLinkRequestFactory applicationLinkRequestFactory = appLink.createAuthenticatedRequestFactory();            

ApplicationLinkRequest request = applicationLinkRequestFactory.createRequest(MethodType.GET, url);

String response = request.execute();

This works fine and performs the proper authentication.

Is there a service similar to the ApplicationLinkService which can make the authenticated REST call to my own Jira server?

I know I can make a a simple REST call using any Java REST client, but since I don't know the username & password, I can not perform the authentication.

Any ideas?

Thank You,

Shay

Yes, take a look at com.atlassian.sal.api.net.TrustedRequestFactory

Something like this:

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.user.ApplicationUser;
import com.atlassian.sal.api.net.Request;
import com.atlassian.sal.api.net.TrustedRequest;
import com.atlassian.sal.api.net.TrustedRequestFactory;
import javax.ws.rs.core.UriBuilder;
import java.net.URI;


String url = "https://example.com/path?query=value";
URI uri = UriBuilder.fromUri(url).build();

ApplicationUser currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser();

TrustedRequestFactory trustedRequestFactory = ComponentAccessor.getComponent(TrustedRequestFactory.class);
TrustedRequest request = trustedRequestFactory.createTrustedRequest(Request.MethodType.GET, url);
request.addTrustedTokenAuthentication(uri.getHost(), currentUser.getName());
String response = request.execute();

Hi @PD Sheehan ,

Thank you for sharing that solution. I tried it in ScriptRunner plugin Console.

TrustedRequestFactory trustedRequestFactory = ComponentAccessor.getComponent(TrustedRequestFactory.class)

When I run the code, a trustedRequestFactory is null. Could you please share how to resolve it, because like in raised question I need to call Jira REST API from ScriptRunner plugin installed on the same Jira instance?

Jira Server v9.4.14

ScriptRunner v.8.1.0

I don't recall if that code used to work on older Jira versions, or if I just made a typo in my original answer.

There are 2 ways you can get that component from scriptrunner with current versions:

TrustedRequestFactory trustedRequestFactory = ComponentAccessor.getOSGiComponentInstanceOfType(TrustedRequestFactory)

Or

import com.onresolve.scriptrunner.runner.customisers.PluginModule
@PluginModule TrustedRequestFactory trustedRequestFactory

Thanks a lot! First solution worked. It's very cool.

TrustedRequestFactory trustedRequestFactory = ComponentAccessor.getOSGiComponentInstanceOfType(TrustedRequestFactory)
