Upload attachment using REST API from C#.NET

[Basanta Padhi]

Hi,

We are creating a tool to migrate Versionone  data to JIRA. So for this I am consuming REST APIs mentioned in "https://developer.atlassian.com/cloud/jira/platform/rest/v3/#api-api-3-issue-issueIdOrKey-remotelink-linkId-put". I am struggling to upload an attachment to an issue. All the time I am getting Statuscode as "200" but there is no attachment to the issue in JIRA. Here in below is my code, please suggest me what I am doing wrong here. 

Snippet

SendFileToServer("XYZ-315");

Snippet

private void SendFileToServer(string IssueKey)
        {
            FileInfo fi = new FileInfo(@"C:\VersionOneAttachments\some.png");
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
            byte[] fileContents = File.ReadAllBytes(fi.FullName);
            
            //https://your-domain.atlassian.net/rest/api/2/issue/XYZ-315/attachments
            string urlPath = ConfigurationSettings.AppSettings.Get("JIRAURLForCreateIssue").ToString();
            Uri webService = new Uri(string.Format("{0}/{1}/attachments", urlPath, IssueKey));
            HttpRequestMessage requestMessage = new HttpRequestMessage(HttpMethod.Post, webService);
            requestMessage.Headers.ExpectContinue = false;
 
            MultipartFormDataContent multiPartContent = new MultipartFormDataContent("----MyGreatBoundary");
            ByteArrayContent byteArrayContent = new ByteArrayContent(fileContents);
            byteArrayContent.Headers.Add("Content-Type", "image/png");
            byteArrayContent.Headers.Add("X-Atlassian-Token", "no-check");
            multiPartContent.Add(byteArrayContent, "this is the name of the content", fi.Name);
            requestMessage.Content = multiPartContent;
 
            HttpClient httpClient = new HttpClient();
            httpClient.DefaultRequestHeaders.Add("Authorization", ConfigurationSettings.AppSettings.Get("JiraAuthorizationKey").ToString());
            httpClient.DefaultRequestHeaders.Add("X-Atlassian-Token", "no-check");
            try
            {
                Task<HttpResponseMessage> httpRequest = httpClient.SendAsync(requestMessage, HttpCompletionOption.ResponseContentRead, CancellationToken.None);
                HttpResponseMessage httpResponse = httpRequest.Result;
                HttpStatusCode statusCode = httpResponse.StatusCode;
                HttpContent responseContent = httpResponse.Content;
 
                if (responseContent != null)
                {
                    Task<String> stringContentsTask = responseContent.ReadAsStringAsync();
                    String stringContents = stringContentsTask.Result;
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }

Any idea will be appreciated.

Thanks in advance

Hi @Basanta Padhi

I got solution!

just change

multiPartContent.Add(byteArrayContent, "this is the name of the content", fi.Name);

to

multiPartContent.Add(byteArrayContent, "file", fi.Name);

 It's worked.

Thanks,
