使用 Build api 调用 Post 时方法不允许

Question

我正在使用 TFS2018 并像这样调用构建 api

internal void UpdateSourceBranches(List<BuildDefinition> defs)
        {
            using (var handler = new HttpClientHandler { Credentials = new NetworkCredential(tfsUser, tfsPass) })
            using (var client = new HttpClient(handler))
            {
                try
                {
                    client.BaseAddress = new Uri(tfsServer);
                    client.DefaultRequestHeaders.Accept.Clear();
                    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

                    foreach (var def in defs)
                    {
                        var buildId = def.Id;
                        var sourceBranch = $"$/{def.Repository.Name}/{def.Project.Name}";
                        var parameters = new Dictionary<string, string> { { "BuildConfiguration", "release" },
                        { "BuildPlatform", "x86|x64|ARM" },
                        { "system.debug", "true" }
                    };

                        var jsonParams = JsonConvert.SerializeObject(parameters);

                        var content = new FormUrlEncodedContent(new[]
                        {
                            new KeyValuePair<string, string>("id", buildId.ToString()),
                            new KeyValuePair<string, string>("sourceBranch", sourceBranch),
                            new KeyValuePair<string, string>("parameters", jsonParams)
                        });

                        var response = client.PostAsync($"DefaultCollection/{def.Repository.Name}/_apis/build/builds?api-version=3.0-preview.1", content);
                        var s = response.Result;
                    }                  
                }
                catch (Exception ex)
                {

                }

            }
        }

但得到以下响应

{StatusCode: 405, ReasonPhrase: '方法不允许', 版本: 1.1, 内容：System.Net.Http.StreamContent，标头：{ Pragma: no-cache X-TFS-ProcessId: ActivityId: X-TFS-Session: X-VSS-E2EID: X-FRAME-OPTIONS: SAMEORIGIN X-VSS-UserData: :user Persistent-Auth: true Lfs-Authenticate: NTLM X-Content-Type-Options: nosniff 缓存控制：无缓存日期：2018 年 3 月 9 日星期五 14:37:16 GMT P3P： CP="CAO DSP COR ADMa DEV CONo TELo CUR PSA PSD TAI IVDo OUR SAMi BUS DEM NAV STA UNI COM INT PHY ONL FIN PUR LOC CNT" 服务器： Microsoft-IIS/10.0 X-AspNet-版本：4.0.30319 X-Powered-By：ASP.NET 内容长度：93 允许：GET 内容类型：应用程序/json； charset=utf-8 过期：-1 }}

知道为什么我得到 Method Not Allowed 吗？

这是不好的回应：

Answer 1

听起来您的 POST 是问题所在，请尝试使用 GET

Answer 2

您应该使用api-version=2.0 而不是3.0-preview.1。

更新代码sn-p：

string con = "{\"definition\": {\"id\": 47},\"sourceBranch\":\"$/CeceScrum/TestCaseProject\",\"parameters\":\"{\\\"BuildConfiguration\\\":\\\"release\\\",\\\"BuildPlatform\\\":\\\"any cpu\\\",\\\"system.debug\\\":\\\"false\\\"}\"}";
                        var patchValue = new StringContent(con, Encoding.UTF8, "application/json");
                        HttpClient httpClient = new HttpClient();
                        string _credentials = Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(string.Format("{0}:{1}", "domain\\username", "password")));
                        httpClient.DefaultRequestHeaders.Accept.Clear();
                        httpClient.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
                        httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", _credentials);
                        var method = new HttpMethod("POST");

                        var request = new HttpRequestMessage(method, "http://TFS2018:8080/tfs/DefaultCollection/CeceScrum/_apis/build/builds?api-version=2.0") { Content = patchValue };

                        httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

                        HttpResponseMessage response = httpClient.SendAsync(request).Result;

                       string re= response.Content.ReadAsStringAsync().Result;
