在 Microsoft Team Foundation Server 2018 中通过 API 从模板创建任务

Question

我正在使用 C# 创建从我们的测试框架 (Selenium) 到 Team Foundation Server (TFS) 2018 的集成（我们的测试已经写入其中）- 集成将根据测试结果在 TFS 中生成工作项.我想从模板创建工作项，但我似乎找不到任何相关文档。我正在使用 Microsoft 发现的 TFS 客户端库 here.

我可以从 TFS 中提取模板：

var client = new HttpClient()
// Client auth stuff removed
var method = new HttpMethod("GET");
var httpRequestMessage = new HttpRequestMessage(method, "http://server:port/tfs/collection/team/project/_api/wit/templates/12345abc");
var httpResponseMessage = client.SendAsync(httpRequestMessage).Result;
WorkItemTemplate tfs_template = httpResponseMessage.Content.ReadAsAsync<WorkItemTemplate>().Result;

用于创建新工作项 here 的 API 看起来相当简单，但我找不到任何方法来连接这两个操作，也找不到使用此调用应用模板的方法。是否可以通过 API 使用模板创建工作项，如果可以，是否有相关文档？

您无法从工作项模板创建工作项。您可以使用工作项模板来查看哪些字段包含一些默认值。此示例用于来自带有 rest api:

                            patchDocument.Add(new JsonPatchOperation()
                            {

                                Operation = Operation.Add,
                                Path = "/fields/" + key,
                                Value = template.Fields[key]

                            });

                        //add any additional fields
                        patchDocument.Add(new JsonPatchOperation()
                        {

                            Operation = Operation.Add,

                            Value = "My critical bug"

                        });

                        var newWorkItem = WitClient.CreateWorkItemAsync(patchDocument, projectName, template.WorkItemTypeName).Result;
                    }

            }
