我尝试了TFS 2015 REST API 身份验证 但是，它提到了请求对象（因为我不能使用 javascript），不确定请求对象在哪里或它的类型。

我正在尝试传递查询 ID，代码应该执行查询并通过 API 获取结果。该解决方案在我的本地工作，但是，在发布到服务器后它似乎不起作用。我还检查了是否可以使用凭据从服务器访问 TFS。

我的代码如下：

    private HttpClientHandler GetTfsCredentials()
    {
        HttpClientHandler handler2 = new HttpClientHandler { UseDefaultCredentials = true };
        handler2.Credentials = new NetworkCredential("username", "password", "domain");
        return handler2;
    }
        private async Task<object> GetQueryResults(string queryId)
    {
        string tfsApiUrl = ConfigurationManager.AppSettings["TfsApiUrl"];
        string tfsProjectName = ConfigurationManager.AppSettings["TfsProjectName"];
        string TfsProjectGuid = ConfigurationManager.AppSettings["TfsProjectGuid"];

        //I tried both credentials and credentials2, but none of them working

        string credentials = Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes($"{""}:{"password"}"));

        string credentials2 = Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes("domain\\username:password") );

        if (!string.IsNullOrEmpty(tfsApiUrl) && !string.IsNullOrEmpty(tfsProjectName)
            && !string.IsNullOrEmpty(Id))
        {
            log.Info("GetQueryResults:: Config values found");
            using (var client = new HttpClient(GetTfsCredentials()) { BaseAddress = new Uri(tfsApiUrl) })
            {
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));

                client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", credentials2);

                HttpResponseMessage response = client.GetAsync($"{tfsProjectName}/_apis/wit/wiql/{Id}").Result;

                log.Info("GetQueryResults:: response.ReasonPhrase" + response.ReasonPhrase.ToString());
                log.Info("GetQueryResults:: response" + response.ToString());
                log.Info("GetQueryResults:: response.IsSuccessStatusCode" + response.IsSuccessStatusCode.ToString());
                string workItemList = null;

                if (response.IsSuccessStatusCode)
                {
                    //do something
                }
            }
        }

        return null;

    }

我收到的错误是：

看起来您正在同时以两种不同的方式进行身份验证：

  • 在GetTfsCredentials-Method 中设置 Windows 身份验证（NTLM 或 Kerberos）
  • 通过添加client.DefaultRequestHeaders.Authorization您尝试设置基本身份验证

您的 TFS 表明（参见WWW-Authenticate标题）它支持承载、协商和 NTLM；但不是基本的。

我会尝试：

  1. 删除和。client.DefaultRequestHeaders.Authorization_ 这应该删除基本身份验证credentialscredentials2
  2. 删除UseDefaultCredentials = true，因为您在下一行设置了显式凭据。UseDefaultCredentials告诉HttpClientHandler使用正在运行的进程的凭据访问 TFS，这可能是您在本地执行时的帐户和在服务器上执行时的服务帐户。
    没有这一行，指定的NetworkCredential应该用于访问 TFS。
