c# - 如何使用C#下载jira中的附件

Question

我正在尝试使用 jira techtalk 从 jira 下载附件，以获取问题和附件。

foreach (var img in issue.fields.attachment)
            {
                JavaScriptSerializer serializer = new JavaScriptSerializer();
                dynamic item = serializer.Deserialize<object>(img.ToString());

                System.Drawing.Image attachImg = Utilities.DownloadImageFromUrl(item["content"].ToString());
                if (attachImg != null) {
                    var sPath = Path.Combine(Server.MapPath("~/Content/Uploads/"), item["filename"].ToString());
                    attachImg.Save(sPath);
                }

            }

在utilities.downloadimagefromurl中，这是完整的代码:

public static System.Drawing.Image DownloadImageFromUrl(string imageUrl)
    {
        System.Drawing.Image image = null;

        try
        {
            System.Net.HttpWebRequest webRequest = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(imageUrl);
            webRequest.AllowWriteStreamBuffering = true;
            webRequest.Timeout = 30000;

            System.Net.WebResponse webResponse = webRequest.GetResponse();

            System.IO.Stream stream = webResponse.GetResponseStream();

            image = System.Drawing.Image.FromStream(stream);

            webResponse.Close();
        }
        catch (Exception ex)
        {
            return null;
        }

        return image;
    }

但返回 null。

有人知道怎么做吗？

谢谢

我在jira API中找到了下载附件的解决方案:我正在使用tecktalk Jira Rest Client https://github.com/techtalk/JiraRestClient

代码如下:

using (WebClient webClient = new WebClient())
{

    webClient.DownloadFile(new Uri(remoteUri + "?&os_username=usernamehere&os_password=passwordhere"), dPath);

}

使用您的 jira 登录用户名和密码。
