Send MentionIssueEvent to external plugin using REAT API

[Kate]

Dear All,

Could you please kindly help. I am trying to create  listner that is reacting on MentionIsuueCommentEvent and send infomation to external plugin via REST API.

Information that needs to be sent is:

• person who added comment
• people tagged in comment
• issue link
• comment body

Hello @Kate ,

This should get you started, The request format will need to conform with the service you are integrating with.

The script below can be added to a comment even in a listener

import java.util.Base64.Encoder

import org.apache.log4j.Level

import groovy.json.JsonSlurper
import groovy.json.JsonParserType

import groovyx.net.http.ContentType
import groovyx.net.http.HTTPBuilder
import groovyx.net.http.Method
import groovyx.net.http.HttpResponseDecorator

import com.atlassian.jira.issue.comments.Comment
import com.atlassian.jira.event.issue.IssueEvent

def apiEndpoint = "https://host:port/base/url"
def resource = "/invoke/this/method"
def token = "Bearer ${getAuthToken()}"

def http = new HTTPBuilder(apiEndpoint)
http.request(Method.POST, ContentType.JSON) { req ->
uri.path = resource
headers.'Authorization' = token
body = buildRequestBody()

response.success = { HttpResponseDecorator resp, data ->
log.info "Response Data: ${data}"
}
}


def getAuthToken() {
   def credentials = "user1 user1"
   def encodedCredentials = Base64.getEncoder().encodeToString(credentials.getBytes())

   return encodedCredentials.toString()
}


def Map<String, Object> buildRequest(IssueEvent event) {
   String action = CommentHelper.getEventAction(event)
   String commentId, username, commentBody
   Comment originalComment = event.params.get('originalcomment') as Comment

   if (COMMENT_DELETED == action) {
      commentId = "${originalComment.id}"
      username = "${originalComment.authorApplicationUser.username}"

   } else {
      if (COMMENT_CREATED == action) {
         commentId = event.comment.id

      } else {
         commentId = originalComment.id
      }

      commentBody = event.comment.body
      username = event.comment.authorApplicationUser.username
   }

   Map<String, Object> commentData = new HashMap<>()
   commentData.put('id',commentId)
   if (commentBody){
      commentData.put('body',commentBody)
   }
   commentData.put('updateAuthor', ['username':username])

  You will need to make this map conform with what the service expects.
   Map<String, Object> body = new HashMap<>()
   body.put('webhookEvent', action)
   body.put('issue', ['key':event.issue.key])
   body.put('comment', commentData)
   // What issue links? issue.getLinks
   // You would need to process the body to get people mentioned

   return body
}

class CommentHelper {
   public static final String COMMENT_CREATED = 'comment_created'
   public static final String COMMENT_EDITED = 'comment_edited'
   public static final String COMMENT_DELETED = 'comment_deleted'

   public static String getEventAction(IssueEvent event) {
      String action = ''

      if (event.comment) {
         if (event.params.originalcomment) {
           action = COMMENT_EDITED

         } else {
            action = COMMENT_CREATED
         }

      } else {
         action = COMMENT_DELETED
      }

     return action
   }
}
