Error when attaching a file via Jira Cloud REST API in ScriptRunner Rest Endpoints

[Michael Smith]

I'm new in HTTP Requests so when I'm trying to attach a file to Jira Cloud REST API in ScriptRunner Rest Endpoints my script failed with error:

My code:

@BaseScript CustomEndpointDelegate delegate 
attach ( httpMethod: "POST") { 
MultivaluedMap queryParams, String body ->
//parsing json
JSONObject json = new JSONObject(new JSONTokener(body))
JSONObject issue = json.getJSONObject("issue")
JSONObject fields = issue.getJSONObject("fields")
JSONArray attachments = fields.getJSONArray("attachment")
JSONObject attachment = attachments.getJSONObject(attachments.length() - 1)
String vendorRequest = fields.getString("customfield_11616")
String linkToFile = attachment.getString("content")
String fileName = StringUtils.substringAfterLast(linkToFile, "/")

//download attachment to entity
CloseableHttpClient httpclient = HttpClients.createDefault()
HttpGet getAttach = new HttpGet(linkToFile)
getAttach.setHeader("X-Atlassian-Token", "no-check")
getAttach.setHeader("Authorization", "Basic xxxxxxxxxxxxxxxxxxxx")
CloseableHttpResponse responseFromServer = httpclient.execute(getAttach)

//responseFromServer.getStatusLine().getStatusCode() code 200 here
HttpEntity entity = responseFromServer.getEntity()
responseFromServer.close()

HttpPost post = new HttpPost("https://cloud-djira.atlassian.net/rest/api/2/issue/" + vendorRequest + "/attachments")
post.setHeader("X-Atlassian-Token", "no-check")
post.setHeader("Authorization", "Basic xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx==")


//i geuss problem here
InputStreamBody fileBody = new InputStreamBody(entity.getContent(), fileName)
HttpEntity entityToAttach = MultipartEntityBuilder.create().addPart("file", fileBody).build()
post.setEntity(entityToAttach)

//script failed here
CloseableHttpResponse responseFromCloud = httpclient.execute(post)

responseFromCloud.close()
httpclient.close()
}

This code works in IDE if it uses like java so maybe it'd better use only groovy in ScriptRunner Rest Endpoints.

Could anyone help?

I fixed that. Just moved line 

responseFromServer.close()

to end of the script

Hi Michael.

I notice you have marked your question as Jira Cloud but this code is for Jira Server and will not be compatible in Jira Cloud as Atlassian does not provide the same Java API in cloud and only provides a Rest API.

I would advise re categorising this ticket as Jira Server if it is related to Server so that users who use the sever version can assist yourself with this question.

Regards,

Kristian
