Scriptrunner REST endpoint authentication

[Максим Зезин]

Hello, I am trying to create REST endpoint to query JIRA REST API in the same instance of JIRA and I have some issues with authorization. While I can use basic authorization, I need to use current logged user context and get rid of hardcoded credentials in endpoint source code.

Here is my script based on some examples on adaptivist site:

import com.onresolve.scriptrunner.runner.rest.common.CustomEndpointDelegate
import groovyx.net.http.HTTPBuilder
import org.apache.http.HttpRequestInterceptor;
import org.apache.http.HttpRequest;
import org.apache.http.protocol.HttpContext;
import groovy.json.JsonSlurper;
import groovy.json.JsonBuilder;
import groovyx.net.http.Method
import groovyx.net.http.ContentType
import groovy.transform.BaseScript
import javax.ws.rs.core.MultivaluedMap
import javax.ws.rs.core.Response
@BaseScript CustomEndpointDelegate delegate 

listProjects( 
    httpMethod: "GET") { MultivaluedMap queryParams -> 
def JIRA_REST_URL = "https://jira-test"
def JIRA_API_URL = JIRA_REST_URL + "/rest/api/2/project"
def httpBuilder = new HTTPBuilder(JIRA_API_URL);
httpBuilder.client.addRequestInterceptor(new HttpRequestInterceptor() {
void process(HttpRequest httpRequest, HttpContext httpContext) {
httpRequest.addHeader('Authorization', 'Basic ' + 'user:pass'.bytes.encodeBase64().toString())
}
})
def rt = [:]
def projects = httpBuilder.request(Method.GET, ContentType.JSON) {
            uri.path = "/rest/api/2/project"
            response.failure = { resp, reader ->
                 log.warn("Failed to query JIRA API: " + reader.text)
             }
        }
 
    rt = [
        items: projects.collect { project ->
            [
                   value: project.id,
                   html : project.key,
                   label: project.key,
            ]
        }
    ]
 

return Response.ok(new JsonBuilder(rt).toString()).build();
}

P.S. I am trying to get project list and issue type list and then use convertToSingleSelect() functionality, may be it is possible to do internally, without REST API calls.

Hey Максим,

If I understand your request correctly, you would like a Custom REST Endpoint where only authenticated JIRA users can retrieve a list of project information.

I have written an example script that will achieve this using the ScriptRunner REST Endpoints. This example will give you a list of projects with their corresponding issue types.

import com.atlassian.jira.component.ComponentAccessor
import com.onresolve.scriptrunner.runner.rest.common.CustomEndpointDelegate
import groovy.json.JsonBuilder
import groovy.transform.BaseScript

import javax.servlet.http.HttpServletRequest
import javax.ws.rs.core.MultivaluedMap
import javax.ws.rs.core.Response

@BaseScript CustomEndpointDelegate delegate

getProjects(httpMethod: "GET", groups: ["jira-users"]) { MultivaluedMap queryParams, String body, HttpServletRequest request ->
    // Get the projects
    def pm = ComponentAccessor.getProjectManager()
    def projects = pm.getProjects()

    def rt = [
        items: projects.collect { project ->
            [
                value     : project.id,
                html      : project.key,
                label     : project.key,
                issueTypes: project.getIssueTypes().collect { issueType ->
                    [
                        id  : issueType.id,
                        name: issueType.name
                    ]
                }
            ]
        }
    ]

    return Response.ok(new JsonBuilder(rt).toString()).build()
}

Enforcing Users

The way that this enforces users is that I have set the groups parameter to "jira-users" (line 12). This means that ONLY authenticated JIRA users who are in the jira-users group can access this resource.

You could also achieve this by getting the user and checking it yourself. An example of this approach is in the SR documentation. I would recommend the approach that I have demonstrated as it is more maintainable.

Getting a list of projects

As you suggested in your post, you can get the projects and issue type data without the need to make a call to another rest endpoint. The example I have given you demonstrates how to do this using the ProjectManager utility.

Hello, Stephen. Thank you for your answer. It was really like I had been trying to reinvent the wheel with my attempts to use JIRA REST. Your solution is exactly what I need.

P.S. I also have found solution for my auth problem : I've forwarded Cookie header from initial endpoint request to JIRA REST.

Hi Максим,

How did you forwarded the Cookie? I ran into the same problem as you - I want to use HTTPBuilder but as a currently logged in user but by default all requests are being sent as anonymous.

Regards,

Bartek

Hi @Stephen Cheesley [Adaptavist], 

Thanks for the solution, but what if the new rest end-point is being called from behaviour or post-function within the same jira instance? how the authentication would be managed? As far as I could test, current user context authentication is not accessible and can not be cascaded to the rest end-point. Is my understanding the right one?

Thanks in advanced,

[Alberto Carrani]

Hi @Stephen Cheesley [Adaptavist] 
your suggestion worked like a charm for my rest point associated to a behaviour!
Thanks,
Alberto

Great to hear @Alberto Carrani ! Happy Scripting :-)
