tfs - 通过 TFS Rest API 创建测试套件时出现 "Response status code does not indicate success: 500 (Internal Server Error)"

Question

在尝试创建 Test Suite 时使用 TFS 2017 REST API ，我收到错误:

System.Net.Http.HttpRequestException - Response status code does not indicate success: 500 (Internal Server Error)

我试过的代码:

using (var client = new HttpClient())
{
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

    string base64StringPat = Convert.ToBase64String(ASCIIEncoding.ASCII.GetBytes(string.Format("{0}:{1}", "", Configs.Pat)));
    AuthenticationHeaderValue authHeader = new AuthenticationHeaderValue("Basic", base64StringPat);
    client.DefaultRequestHeaders.Authorization = authHeader;

    string url = "http://vmctp-tl-mtm:8080/tfs/DefaultCollection/SgkProject/_apis/test/Plans/7/Suites/8?api-version=1.0";
    var content = new StringContent("{\"suiteType\":\"StaticTestSuite\",\"name\":\"Module1\"}", Encoding.UTF8, "application/json");
    using (HttpResponseMessage response = client.PostAsync(url, content).Result)
    {
        response.EnsureSuccessStatusCode();
        string responseBody = await response.Content.ReadAsStringAsync();
        Console.WriteLine(responseBody);
    }
}

我使用 Microsoft 的此文档来调用 API: Create a test suite

请指导我解决问题。

HTTP 代码 500 表示这是您服务器上的错误。服务器在尝试处理此 POST 请求时抛出异常。

所以，这个错误与HttpClient无关。 .只需先检查您的服务器，看看是什么导致了异常。

一种可能是指定的 content type不是服务器所期望的。发布 StringContent将内容类型设置为 text/plain .您可能会发现服务器不喜欢那样。在这种情况下，只需尝试找出服务器期望的媒体类型并设置 Headers.ContentType的StringContent实例。

无论如何，我可以通过以下示例创建套件，您可以尝试一下:

using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;

namespace CreateTestSuite
{
    class Program
    {
        public static void Main()
        {
            Task t = CreateTestSuite();
            Task.WaitAll(new Task[] { t });
        }
        private static async Task CreateTestSuite()
        {
            try
            {
                var username = "username";
                var password = "password";

                using (var client = new HttpClient())
                {
                    client.DefaultRequestHeaders.Accept.Add(
                        new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));

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

                    string url = "http://server:8080/tfs/DefaultCollection/LCScrum/_apis/test/plans/212/suites/408?api-version=1.0";
                    var content = new StringContent("{\"suiteType\":\"StaticTestSuite\",\"name\":\"Module3\"}", Encoding.UTF8, "application/json");
                    using (HttpResponseMessage response = client.PostAsync(url, content).Result)
                    {
                        response.EnsureSuccessStatusCode();
                        string responseBody = await response.Content.ReadAsStringAsync();
                        Console.WriteLine(responseBody);
                    }

                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
        }
    }
}
