Add an attachment to existing Issue

[Bindiya Vikram Naik]

As I got to know we cannot add an attachment at the time of creating issue. So I am trying to add an attachment to existing Issue.

The below code I have got from the already attached attachment of existing Issue. Do I need to give all the parameters below for POST?

My rest api code looks like this below:

POST URL: https://tataunistore.atlassian.net/rest/api/3/issue/Demo-230/attachments

"attachment" :
[
"0" :

"self" :

Hi @Bindiya Vikram Naik 

No you definitely don't need all those.

I implemented the code as per the answer by Jeff Caron in https://stackoverflow.com/questions/11886316/how-to-post-attachment-to-jira-using-rest-api and it works perfectly

sorry I could not understand.

What parameters I need to share when doing it thru REST api, What should I send  payload? not clear with that. or rather how do I send the file to be uploaded in payload.

I also get below error:

An unexpected error has occurred: (SyntaxError) : Failed to execute 'setRequestHeader' on 'XMLHttpRequest': 'multipart/form-data' is not a valid HTTP header field name.

Hi @Bindiya Vikram Naik 

Below is my C# code (in it's simplest form, with no error checking) that I use to add an attachment to an existing issue.

It is called by passing in the issue key and the FileInfo version of the file

   AddAttachment("ABC-1234", fname);

public static void AddAttachment(string key, FileInfo Attachment)
{
HttpWebRequest request = null;

string fullURL = @"/rest/api/3/issue/" + key + "/attachments";

var boundary = string.Format("----------{0:N}", Guid.NewGuid());
var content = new MemoryStream();
var writer = new StreamWriter(content);

var fs = new FileStream(Attachment.FullName, FileMode.Open, FileAccess.Read);
var data = new byte[fs.Length];
fs.Read(data, 0, data.Length);
fs.Close();

writer.WriteLine("--{0}", boundary);
writer.WriteLine("Content-Disposition: form-data; name=\"file\"; filename=\"{0}\"", Attachment.Name);
writer.WriteLine("Content-Type: application/octet-stream");
writer.WriteLine();
writer.Flush();

content.Write(data, 0, data.Length);

writer.WriteLine();

writer.WriteLine("--" + boundary + "--");
writer.Flush();
content.Seek(0, SeekOrigin.Begin);

request = WebRequest.Create(fullURL) as HttpWebRequest;
request.Method = "POST";
request.ContentType = string.Format("multipart/form-data; boundary={0}", boundary);
request.Accept = "application/json";
request.Headers.Add("Authorization", "Basic " + GetEncodedCredentials());
request.Headers.Add("X-Atlassian-Token", "nocheck");
request.ContentLength = content.Length;

using (Stream requestStream = request.GetRequestStream())
{
content.WriteTo(requestStream);
requestStream.Close();
}
}

If this (or what you're using) doesn't work for you, you'll need to show some code and details here so someone can try to understand what's going wrong for you.

Hello @Warren @Ravi Sagar _Sparxsys_ 

I am trying it on Talent APItester extension in chrome. Kindly find the attachment for more clear picture.

POST URL: https://tataunistore.atlassian.net/rest/api/3/issue/256509/attachments

Problem statement: Now I get 200 Response code but still attachment is not getting uploaded in respective issue. Please help.

Hi @Bindiya Vikram Naik 

Ah okay, so this APITester that you're using is a bit like Postman in that you don't write any code? In that case, I can't really help much because I know nothing about APITester or what's going on "under the hood".

Sorry
