JAVA upload attachment to JIRA Issue via REST API by HttpURLConnection method? Edited

Hi everyone,

can help me anyone?

I need upload image or other files to JIRA by REST API, but i cant use HttpPost method, because with this method i have problem with company proxy. I tryed this:

public void AddAttachment(String DefectId) throws IOException, JSONException {

String CHARSET = "UTF-8";
BufferedReader br = null;


String path = "C:\\somefile.txt";
File file = new File(path);

URL url = new URL(myServer + "/rest/api/2/issue/" + DefectId + "/attachments");
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxy", 8080));
HttpURLConnection conn = (HttpURLConnection) url.openConnection(proxy);
conn.setRequestProperty("Cookie", cookieValue);
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("X-Atlassian-Token", "nocheck");


OutputStream outputStream = conn.getOutputStream();
PrintWriter writer = new PrintWriter(new OutputStreamWriter(outputStream, CHARSET), true);
try ( FileInputStream inputStream = new FileInputStream(file);) {
byte[] buffer = new byte[4096];
int bytesRead;
while ((bytesRead = != -1) {
outputStream.write(buffer, 0, bytesRead);

if (200 <= conn.getResponseCode() && conn.getResponseCode() <= 299) {
br = new BufferedReader(new InputStreamReader(conn.getInputStream(),
} else {
br = new BufferedReader(new InputStreamReader(conn.getErrorStream(),

String lineOfResponse = "";
StringBuilder strBuild = new StringBuilder();

while ((lineOfResponse = br.readLine()) != null) {

String response = strBuild.toString();

Hey Tomas,


I think that you may implement something similar to the described on the following page:

Does it fit your needing?

This is how i uploaded properly, dependencies okhttp and okio

private static void upload(File file) throws Exception{
final String address = "https://domain/rest/api/2/issue/issueId/attachments";
final OkHttpClient okHttpClient = new OkHttpClient();
final RequestBody formBody = new MultipartBody.Builder()
.addFormDataPart("file", file.getName(),
RequestBody.create(MediaType.parse("text/plain"), file))
final Request request = new Request.Builder().url(address).post(formBody)
.addHeader("X-Atlassian-Token", "no-check")
.addHeader("Authorization", "Basic api_token_from_your_account")
final Response response = okHttpClient.newCall(request).execute();
System.out.println(response.code() + " => " + response.body().string());
