【问题描述】：

我正在尝试为工作项调用 post API(DevOps)，但它显​​示状态“错误请求”。

如果我调用一些 GET API(DevOps)，它工作正常。我按照以下链接调用 POST API：

https://docs.microsoft.com/en-us/rest/api/azure/devops/wit/wiql/query%20by%20wiql?view=azure-devops-rest-5.0

代码：

using (var client = new HttpClient())
                
                   string content = "'query': 'Select [System.Id], [System.Title], [System.State] From WorkItems'";
                    client.BaseAddress = new Uri("http://YYYYY.com:8080/tfs/YY");  //url of your organization
                    client.DefaultRequestHeaders.Accept.Clear();
                    client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
                    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", credentials);
                    var response = client.PostAsJsonAsync(new Uri("http://YYYYY.com:8080/tfs/YY/_apis/wit/wiql?api-version=1.0"), content).Result;
                    if (response.IsSuccessStatusCode)
                    
                        Console.Write("Success");
                    
                    else
                        Console.Write("Error");
                

【问题讨论】：

如果您使用的是本地 TFS（根据您查询的 URI，您似乎在使用它），什么版本？

【参考方案1】：

你可以试试下面的代码：

var personalaccesstoken = "xxxxxxxxxx";
var base64Token = Convert.ToBase64String(Encoding.ASCII.GetBytes($":personalaccesstoken"));  
using (HttpClient client = new HttpClient())

    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", base64Token);
    var requestMessage = new HttpRequestMessage(HttpMethod.Post, "http://tfsserver:8080/tfs/DefaultCollection/_apis/wit/wiql?api-version=1.0");
    requestMessage.Content = new StringContent("\"query\": \"select [System.Id], [System.Title], [System.State] from WorkItems\"", Encoding.UTF8, "application/json");
    using (HttpResponseMessage response = client.SendAsync(requestMessage).Result)
    
        response.EnsureSuccessStatusCode();
