版本一 API 客户端的附件

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版本一请求？ 假设我们已经有了文件名和票证 ID。 我发现这是用 ObjectModel 完成的，但没有我可以用 API 客户端理解的任何代码。

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）。 在这里，我有 OID，而不是 ID。 您可以查询ID.Number（例如B-1234），如果这是您拥有的。

        private static readonly bool _integrated = false;

        static void Main(string[] args)
        {
            //string file = args[0];
            string file = @"C:UsersMIRVINDesktopTraining WheelsSampleAttachmentbinDebugtestfile.rtf";
            if (File.Exists(file))
            {
                Console.WriteLine("Uploading {0}", file);

                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");

                            int read = input.Read(buffer, 0, buffersize);
                            if (read == 0)
                                break;
                            output.Write(buffer, 0, read);
                        }
                    }

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