Question

在调试会话中使用IIS Express和VS 2015中的Postman（浏览器）时，以下请求可以正常工作：

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

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

这是我的web api控制器方法

[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);
}

虽然当我尝试使用完全相同的请求数据访问此方法时，它返回405.在深入挖掘后，我发现内部已完成重定向（302）。但无法找到有关IIS日志中发生的事情以及原因的任何信息。

到目前为止，我已经删除了WebDAV，属性是Http而不是Mvc，路由配置的所有星座（belkow是我现在的星座）

    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 }
        );
    }

这是我的init方法

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

真的不知道该怎么办...现在挣扎了2天，我不知道在哪里可以看得更远。

这是HttpClient调用

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;
            }

这是我的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; }
}

有趣的是，当我在HttpClient上发布POST时，它似乎没有到达WebApi模块...

Answer 1

将FormsAuth和SessionProvider模块中的cookieless =“AutoDetect”更改为 cookieless =“UseCookies”，一切都按预期工作。

HttpClient POST到WEB API方法返回405（方法不允许）
