How to get attachment content using REST API version 3

Danil Luchin

Hi,
I'm trying to get attachment (image) content and convert it to base64 string using this endpoint GET /rest/api/3/attachment/content/{id}
I'm getting the content as escaped ascii unicode (I guess)
and it looks like this:
��\u0000\u0010JFIF\u0000\u0001\u0002\u0000\u0000d\u0000d\u0000\u0000��\u0000\u0011Ducky\u0000\u0001\u0000\u0004....

I've been trying to unescape it, convert manually etc. – nothing worked out.
Could you please confirm that this endpoint is working correctly, as I can see Experimental tag on it?
Could you please give me a hint how to decode this binary and convert it to base64?

Also, I think it could be helpful to give an option to download the attachment as base64 string, at lease for the images.

Thank you!

That content should be in bytes. You're getting binary string data. What you should do is write that content into a file data structure if you simply want to get the file data. If you want to convert to base64, I believe you could simply just convert the entire structure by decoding it to plain strings prior to using base64.

Thanks, there was an issue in jira.js
now it works just fine!

Hi Danil,
I have finally achieve 2 ways to resolve this.

The first is via Scriptrunner,

we can get the BinaryArray you commented "��\u0000\u0010JFIF\u0000\u0001\u0002\u0000\u0000d\u0000d\u0000\u0000��\u0000\u0011Ducky\u0000\u0001\u0000\u0004...." making use of the Attachment Content API. You can test this on the Script Console:

def issueKey = 'EXAMPLE-1234'

def result = get('/rest/api/2/issue/' + issueKey)
.header('Content-Type', 'application/json')
.asObject(Map)
if (result.status == 200){
def bodyfields = result.body.fields
def attachment = bodyfields.attachment[0]
def attachmentid = attachment.id
def attachmentfilename = attachment.filename
def attachmenttype = attachment.mimeType
def result2 = get('/rest/api/3/attachment/content/' + attachmentid)
.header('Content-Type', 'application/json')
.asBinary()

def attachmentcontent = result2.body.bytes.encodeBase64().toString()

The second way is via Zapier,

You would need to use Automation for Jira and Webhooks by Zapier to send and capture attachment related data, such as filename, id, filetype (as you need) and in a second Zapier event you would need to use Code Python by Zapier and use this code:

import requests
import base64
import codecs
id = input_data['idattachment']

url = "https://yourdomain.attlassian.net/rest/api/3/attachment/content/"+id
r=requests.get(url , headers={"Content-Type":"application/json","Authorization":"Basic YOUR_TOKEN","Connection":"keep-alive"}, params={"redirect": "false"})attachment_bytes = r.content
base64input = codecs.encode(attachment_bytes,'base64').decode('utf-8')
attachment_text  = bytes(base64input, 'utf-8').decode('utf-8')
return {'bytes':attachment_text }

in both ways you should be able to use the base64 encripted attachment to send it to another app.

The first vía worked for me. Thank you!!
