Question

有人可以展示一些示例代码，说明如何使用API客户端将外部文件附加到第一版请求吗？假设我们已经有文件名和票证ID。我发现这已经完成了ObjectModel，但没有用API客户端可以理解的任何代码。

Answer 1

此示例将rtf文件附加到项目（范围）。您必须将范围更改为您选择的资产（可能是故事或缺陷）。这里我有OID，而不是ID。您可以查询ID.Number（例如B-1234），如果这是您所拥有的。

        private static readonly string _username = "username";

        private static readonly string _password = "passwerd";

        private static readonly bool _integrated = false;



        static void Main(string[] args)
        {

            //string file = args[0];
            string file = @"C:\Users\MIRVIN\Desktop\Training Wheels\SampleAttachment\bin\Debug\testfile.rtf";

            if (File.Exists(file))
            {

                Console.WriteLine("Uploading {0}", file);
                string mimeType = MimeType.Resolve(file);

                IMetaModel metaModel = new MetaModel(new V1APIConnector(ApplicationURL + "meta.v1/"));
                IServices services = new Services(metaModel, new V1APIConnector(ApplicationURL + "rest-1.v1/", _username, _password, _integrated));
                IAttachments attachments = new Attachments(new V1APIConnector(ApplicationURL + "attachment.img/", _username, _password, _integrated));


                //cleanjeans scope
                Oid attachmentContext = Oid.FromToken("Scope:5067", metaModel);



                IAssetType attachmentType = metaModel.GetAssetType("Attachment");

                IAttributeDefinition attachmentNameDef = attachmentType.GetAttributeDefinition("Name");

                IAttributeDefinition attachmentContentDef = attachmentType.GetAttributeDefinition("Content");

                IAttributeDefinition attachmentContentTypeDef = attachmentType.GetAttributeDefinition("ContentType");

                IAttributeDefinition attachmentFileNameDef = attachmentType.GetAttributeDefinition("Filename");



                Asset newAttachment = services.New(attachmentType, attachmentContext);

                newAttachment.SetAttributeValue(attachmentNameDef, "New Attachment");

                newAttachment.SetAttributeValue(attachmentContentDef, string.Empty);

                newAttachment.SetAttributeValue(attachmentContentTypeDef, mimeType);

                newAttachment.SetAttributeValue(attachmentFileNameDef, file);

                services.Save(newAttachment);

                //Setup and attach the payload

                string attachmentKey = newAttachment.Oid.Key.ToString();
                int buffersize = 4096;

                using (FileStream input = new FileStream(file, FileMode.Open, FileAccess.Read))
                {

                    using (Stream output = attachments.GetWriteStream(attachmentKey))
                    {

                        byte[] buffer = new byte[buffersize];

                        for (; ; )
                        {

                            int read = input.Read(buffer, 0, buffersize);

                            if (read == 0)

                                break;

                            output.Write(buffer, 0, read);

                        }

                    }

                }

                attachments.SetWriteStream(attachmentKey, mimeType);



                Console.WriteLine("{0} uploaded", file);

            }

            else

                Console.WriteLine("{0} does not exist", file);

        }

    }

        }
