我们正在移植我们的产品。NET将代码从SOAP集合到其他程序。NET API。到目前为止,REST API似乎更快、更易于使用,因为在Rally工作区中,每次工作产品自定义字段发生更改时,都没有WSDL可以中断。
不过,当我们试图复制上传附件的能力时,我遇到了一个问题。我们遵循的程序与本文概述的程序非常相似:
Rally SOAP API-如何向分层需求添加附件
将图像读入系统。绘画形象我们使用ImageToByteArray函数将图像转换为字节数组,然后将其分配给首先创建的AttachmentContent。
然后,创建附件,并连接到附件内容和层次要求。
所有创建事件都运行良好。内容对象创建得很好。然后创建了名为“我mage.png”的新附件并链接到故事。但是当我从拉力赛下载结果附件时,我mage.png零字节!我尝试了不同的图像,JPEG的,巴布亚新几内亚的,等等,都有相同的结果。
下面包含了显示我们过程的代码摘录。有什么明显的东西我错过了吗?提前感谢。
// .... Read content into a System.Drawing.Image called imageObject ....
// Convert Image to byte array
byte[] imageBytes = ImageToByteArray(imageObject, System.Drawing.Imaging.ImageFormat.Png);
var imageLength = imageBytes.Length;
// AttachmentContent
DynamicJsonObject attachmentContent = new DynamicJsonObject();
attachmentContent["Content"] = imageBytes ;
CreateResult cr = restApi.Create("AttachmentContent", myAttachmentContent);
String contentRef = cr.Reference;
Console.WriteLine("Created: " + contentRef);
// Set up attachment
DynamicJsonObject newAttachment = new DynamicJsonObject();
newAttachment["Artifact"] = story;
newAttachment["Content"] = attachmentContent;
newAttachment["Name"] = "Image.png";
newAttachment["ContentType"] = "image/png";
newAttachment["Size"] = imageLength;
newAttachment["User"] = user;
// Create the attachment in Rally
cr = restApi.Create("Attachment", newAttachment);
String attachRef = cr.Reference;
Console.WriteLine("Created: " + attachRef);
}
public static byte[] ImageToByteArray(Image image, System.Drawing.Imaging.ImageFormat format)
{
using (MemoryStream ms = new MemoryStream())
{
image.Save(ms, format);
// Convert Image to byte[]
byte[] imageBytes = ms.ToArray();
return imageBytes;
}
}
这个问题也让我困惑了一段时间——大约一周前终于解决了。
两点意见:
