使用 C# 使用 Azure DevOps Rest API 创建工作项

Question

我无法使用 Azure DevOps REST API 创建工作项，如中所述 工作项 - 创建中创建工作项

要求：

https://dev.azure.com/{organization}/MyTestProject/_apis/wit/workitems/$Task?api-version=6.0-preview.3

Request Body:
[
  {
    "op": "add",
    "path": "/fields/System.Title",
    "value": "Task2"
  }
]

获取响应的代码（注意此代码适用于所有其他 POST 请求）：

using (HttpResponseMessage response = client.SendAsync(requestMessage).Result)
      {
         response.EnsureSuccessStatusCode();
         JsonResponse = await response.Content.ReadAsStringAsync();
      }

Response: 400

有人可以建议吗？

查看您的完整示例可能会有所帮助。但是，这里是工作示例Newtonsoft.Json（不要忘记创建个人访问令牌）：

using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApp2
{
    class Program
    {
        static void Main(string[] args)
        {
            string PAT = "<personal access token>"; //https://docs.microsoft.com/en-us/azure/devops/organizations/accounts/use-personal-access-tokens-to-authenticate?view=azure-devops&tabs=preview-page
            string requestUrl = "https://dev.azure.com/<my_org>/<my_project>/_apis/wit/workitems/$Task?api-version=5.0";
            try
            {
                List<Object> flds = new List<Object>
                {
                    new { op = "add", path = "/fields/System.Title", value = "Title" }
                };


                string json = JsonConvert.SerializeObject(flds);

                HttpClientHandler _httpclienthndlr = new HttpClientHandler();

                using (HttpClient client = new HttpClient(_httpclienthndlr))
                {
                    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(
                System.Text.ASCIIEncoding.ASCII.GetBytes(
                string.Format("{0}:{1}", "", PAT))));


                    var request = new HttpRequestMessage(new HttpMethod("PATCH"), requestUrl)
                    {
                        Content = new StringContent(json, Encoding.UTF8, "application/json-patch+json")
                    };

                    HttpResponseMessage responseMessage = client.SendAsync(request).Result;
                }

            }
            catch (Exception ex)
            {

            }
        }
    }
}

此外，您可以考虑将.NET 客户端库用于 Azure DevOps 和 TFS。示例如下：使用 .NET 客户端库在 Azure DevOps Services 中创建错误

需要 application/json-patch+json。
