c# – 调试自托管的WebApi应用程序

我有一个WebApi应用程序与以下控制器：

public class ContentController : ApiController
{
    [HttpPost]
    public HttpResponseMessage Post(string contentType)
    {
        //do stuff
        return new HttpResponseMessage(HttpStatusCode.OK);
    }
}

路线看起来像这样

routes.MapHttpRoute("content", 
    "api/content/{contentType}", 
    new { controller = "Content", contentType = RouteParameter.Optional });

当我在IIS / cassini中托管服务时,如果我按照预期POST到api / content /,那么我的控制器操作就会被命中.

然而,

我有一个测试项目,SelfHosts这个api

using (var client = new HttpClient(Server))
{
    var result = client.PostAsync(BaseAddress + "api/content/whatever"

    var message = result.Content.ReadAsStringAsync().Result;
}

如果我调试单元测试,并进入它,结果是：

{StatusCode: 500, ReasonPhrase: ‘Internal Server Error’, Version: 1.1, Content: System.Net.Http.ObjectContent`1[[System.Web.Http.HttpError, System.Web.Http, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]], Headers:
{
Content-Type: application/json; charset=utf-8
}}

无益,消息实际上是公正的

An error has occurred

有没有办法我可以调试自我托管的WebApi来找出导致此错误的原因？

建立

服务器只是一个来自基类的HttpServer,它拥有我自己托管的服务器,如下所示：

var httpConfig = new HttpSelfHostConfiguration(BaseAddress);

new ApiServiceConfiguration(httpConfig).Configure();

var server = new HttpSelfHostServer(httpConfig);
server.OpenAsync().Wait();
Server = server;

解决方法:

如果启用跟踪并添加Trace.Listeners.Add(新的ConsoleTraceListener()),则会收到更详细的错误消息.但是,您的问题很可能与您尝试序列化的对象无法序列化有关.
