Question

我正在尝试使用以下代码创建工作项：

HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create("https://xxx.visualstudio.com/defaultcollection/xxx/_apis/wit/workitems/$Bug?api-version=1.0");
httpWebRequest.ContentType = "application/json-patch+json";
httpWebRequest.Credentials = new NetworkCredential("me",Settings.Default.token);
httpWebRequest.Method = "PATCH";
JavaScriptSerializer serializer = new JavaScriptSerializer();
string json = serializer.Serialize(new
{
    op="add",
    path= "/fields/System.Title",
    value="New bug from application"
});
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
    streamWriter.Write(json);
}
HttpWebResponse httpResponse = null;
try { httpResponse = (HttpWebResponse) httpWebRequest.GetResponse(); }
catch (WebException e)
{
    //Exception catched there, error 404
    Console.WriteLine(e.Status); //Writes ProtocolError
    throw;
}
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
    string responseText = streamReader.ReadToEnd();
    Console.WriteLine(responseText);
}

但是我收到错误404（未找到）。当我改变方法（PUT或POST）时，我得到了一个可视工作室页面的代码。

当我要去https://xxx.visualstudio.com/defaultcollection/xxx/_apis/wit/workitems/$Bug?api-version=1.0时，我可以看到一些json。所以这不是URL错误。

我终于可以做我想做的事了：

public async Task CreateBug(Bug bug)
{
    string token = Settings.Default.token;
    string requestUrl = "https://xxx.visualstudio.com/defaultcollection/xxx/_apis/wit/workitems/$Bug?api-version=1.0";
    HttpClientHandler httpClientHandler = new HttpClientHandler
    {
        Proxy = this.GetProxy(),
        UseProxy = true,
        UseDefaultCredentials = true
    };
    HttpClient httpClient = new HttpClient(httpClientHandler);
    httpClient.DefaultRequestHeaders.Accept.Add(
                new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));

    httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
        Convert.ToBase64String(
            System.Text.ASCIIEncoding.ASCII.GetBytes(
                string.Format("{0}:{1}", "me", token))));
    var method = new HttpMethod("PATCH");
    var request = new HttpRequestMessage(method, requestUrl)
    {
        Content = new StringContent(GetStrJsonData(), Encoding.UTF8,
            "application/json-patch+json")
    };
    HttpResponseMessage hrm = await httpClient.SendAsync(request);
    Response = hrm.Content;
}

我使用的是HttpClient而不是HttpWebRequest
