のHttpClient POST 405を返します（メソッド許可されていない）

Question

は完璧に動作します：

POST http://localhost:51072/api/cs/processor/process 

{ 
'code':'TEST', 
    'mode':0 
} 

これは私のウェブAPIコントローラです私は深く掘った後、それは405を返しまったく同じ要求データでこのメソッドにアクセスしようとする方法

[RoutePrefix("api/cs")] 
public class ProcessorController : UmbracoApiController 
{... 

[AllowAnonymous] 
[Route("processor/process")] 
[HttpPost()] 
public IHttpActionResult Process([FromBody] ProcessSurvey dto) 
{ 
    if (!HttpContext.Current.Request.IsLocal) 
    { 
     return Content(HttpStatusCode.Forbidden, "Not allowed to start survey from remote host."); 
    } 
    ProcessSurveyResponse resp = new ProcessSurveyResponse(); 
    switch (dto.Code) 
    { 
     case "ITS": 
      resp = Execute(dto.Mode); 
      break; 
     default: 
      resp.Message = "Test successful!"; 
      break; 
    } 
    return Content(HttpStatusCode.Created, resp); 
} 

私は内部的にリダイレクト（302）を行うのことがわかってきましたが。しかし、何が起きているのか、なぜIISログに何があるのか​​についての情報は見つけられません。

私がこれまで行ってきたWebDAVを除去してどのような、属性があるのHttpないMVC、ルート設定のすべての星座（belkowが私の現在のものです）

public static void Register(HttpConfiguration config) 
    { 
     // Attribute routing. 
     config.MapHttpAttributeRoutes(); 


    config.Routes.MapHttpRoute(
     name: "DefaultApiFull", 
     routeTemplate: "api/{controller}/{action}/{id}", 
     defaults: new { id = RouteParameter.Optional }); 

    config.Routes.MapHttpRoute(
      name: "DefaultApi", 
      routeTemplate: "api/{controller}/{id}", 
      defaults: new { id = RouteParameter.Optional } 
     ); 
    } 

と、これは私のinitメソッドである

GlobalConfiguration.Configure(WebApiConfig.Register); //WebApi 2 Register method 

本当に何をすべきか分かりません...今は2日間苦労していますし、どこをもっと見てもわかりません。ここで

はHttpClientをが

using (var client = new HttpClient()) 
      { 
       client.DefaultRequestHeaders.Clear(); 
       client.DefaultRequestHeaders.ExpectContinue = false; 
       client.DefaultRequestHeaders.Accept.Clear(); 
       client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("*/*")); 
       var json = JsonConvert.SerializeObject(dto); 
       StringContent content = new StringContent(json, Encoding.UTF8, "application/json"); 
       log.Debug("Call " + baseUrl); 
       HttpResponseMessage response = await client.PostAsync("http://localhost:51072/api/cs/surveyprocessor/process/", content); 
       string data = await response.Content.ReadAsStringAsync(); 
       if (response.IsSuccessStatusCode) 
       { 
        result = JsonConvert.DeserializeObject<ProcessSurveyResponse>(data); 
       } 
       else 
       { 
        result.Message = data; 
       } 
       return result; 
      } 

を呼び出し、ここで私のDTO

public class ProcessSurvey 
{ 
    [JsonProperty(PropertyName = "mode")] 
    public int Mode { get; set; } 
    [JsonProperty(PropertyName = "code")] 
    public string Code { get; set; } 
    [JsonProperty(PropertyName = "customers")] 
    public IList<int> Customers { get; set; } 
} 

私はHttpClientを介して投稿するとき、WEBAPIモジュールに到達していないと思われることは興味深い何です...

FormsAuthおよびSessionProviderモジュールのcookieless = "AutoDetect"をcookieless = "UseCookies"に変更すると、すべてが期待どおりに機能します。
