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

[Tomáš Pilný]

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;
 
 Authorization();
 
 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.setRequestMethod("POST");
 conn.setDoOutput(true);
 conn.setDoInput(true);
 conn.setRequestProperty("Cookie", cookieValue);
 conn.setRequestProperty("Content-Type", "application/json");
 conn.setRequestProperty("X-Atlassian-Token", "nocheck");

 System.out.println(conn.getResponseCode());
 System.out.println(conn.getResponseMessage());
 
 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 = inputStream.read(buffer)) != -1) {
 outputStream.write(buffer, 0, bytesRead);
 }
 outputStream.flush();
 }
 writer.flush();

 
 if (200 <= conn.getResponseCode() && conn.getResponseCode() <= 299) {
 br = new BufferedReader(new InputStreamReader(conn.getInputStream(),
 "UTF-8"));
 } else {
 br = new BufferedReader(new InputStreamReader(conn.getErrorStream(),
 "UTF-8"));
 }
 
 String lineOfResponse = "";
 StringBuilder strBuild = new StringBuilder();
 
 while ((lineOfResponse = br.readLine()) != null) {
 strBuild.append(lineOfResponse);
 }
 
 String response = strBuild.toString();
 
 System.out.println(response);
 
 conn.disconnect();
 br.close();

 
 }

 I have problem how a can id file(image or document) to output stream.

Authorization(by Cookies) i have in other methods and working fine.

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()
            .setType(MultipartBody.FORM)
            .addFormDataPart("file", file.getName(),
                    RequestBody.create(MediaType.parse("text/plain"), file))
            .build();
    final Request request = new Request.Builder().url(address).post(formBody)
            .addHeader("X-Atlassian-Token", "no-check")
            .addHeader("Authorization", "Basic api_token_from_your_account")
            .build();
    final Response response = okHttpClient.newCall(request).execute();
    System.out.println(response.code() + " => " + response.body().string());
}

okhttp3 or okhttp dependency?

File fileUpload = new File("Path to file");

/* Path to file : In windows- "C:\\Users\\Abhishek\\Downloads\\test.png"

                       In Linux - "/home/dir/test.png"

*/
HttpClient httpClient = HttpClientBuilder.create().build();
HttpPost postRequest = new HttpPost(URL);

/*  URL : https//{jira Base Url}/rest/api/2/issue/{issueKey}/attachments

*/

String userpass = "username" + ":" + "Password";
String basicAuth = "Basic " + new String(new Base64().encode(userpass.getBytes()));
postRequest.setHeader("Authorization", basicAuth);
postRequest.setHeader("X-Atlassian-Token", "nocheck");
MultipartEntityBuilder entity = MultipartEntityBuilder.create();
entity.addPart("file", new FileBody(fileUpload));
postRequest.setEntity(entity.build());

HttpResponse jiraResponse = null;
try {
jiraResponse = httpClient.execute(postRequest);
} catch (ClientProtocolException f) {
f.printStackTrace();
} catch (IOException f) {
f.printStackTrace();
}

if (jiraResponse.getStatusLine().getStatusCode() == 200) {
System.out.println("Adding attachment to JIRA passed");
Files.deleteIfExists(targetPath);
} else {
System.out.println("Adding attachment to JIRA failed");
}

Hey Tomas,

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

• https://www.techcoil.com/blog/how-to-upload-a-file-via-a-http-multipart-request-in-java-without-using-any-external-libraries/

Does it fit your needing?
