此资源不支持请求实体的媒体类型“application/xml”

Question

我试图通过XLIFF内容在以下函数的参数，我得到错误：

public IHttpActionResult ProcessSmartlingTranslation([FromBody]xliff xliff)
       {
           return Content(HttpStatusCode.BadRequest, "Any object");
       }

{“message”：“此资源不支持请求实体的媒体类型'application/xml'。”，“exceptionMessage”：“没有MediaTypeFormatter可用于从媒体类型为“application/xml”的内容中读取类型为“xliff”的对象。”，“exceptionType”：“System.Net.Http.UnsupportedMediaTypeException”，“stackTrace”：“在System.Net.Http.HttpContentExtensions.ReadAsAsync[T]（HttpContent内容，类型，IEnumerable1格式化程序，IFormatterLogger格式化程序记录器，CancellationToken CancellationToken）\r\n在System.Net.Http.HttpContentExtensions.Readasync（HttpContent内容、类型、IEnumerable1格式化程序、IFormatterLogger格式化程序记录器、CancellationToken CancellationToken）\r\n在系统中。网状物Http。模型绑定。FormatterParameterBinding。ReadContentAsync（HttpRequestMessage请求，类型类型，IEnumerable`1格式化程序，IFormatterLogger格式化程序记录器，CancellationToken CancellationToken）“}

我将如何解决这个问题？

完整的代码如下：

// <summary>
   /// XliffModel created
   /// </summary>
   public class xliff
   {
       /// <summary>
       /// file getter setter method
       /// </summary>
       public string file { get; set; }
       /// <summary>
       /// body getter setter method
       /// </summary>
       public string body { get; set; }
   }
   /// <summary>
   /// Web api for smartling translation processing
   /// </summary>
   /// <seealso cref="ApiController" />
   public class SmartlingController : ApiController
   {
       #region Public Methods

       /// <summary>

       /// <response code="200">Get approved blog comments</response>
       /// <response code="404">Not found</response>
       /// <returns>IHttpActionResult</returns>
       [Route("api/smartling/ProcessSmartlingTranslation")]
       [VersionedRoute("", 1)]
       [ResponseType(typeof(HttpResponseMessage))]
       [HttpPost]
       public IHttpActionResult ProcessSmartlingTranslation([FromBody]xliff xlf)
       {
           return Content(HttpStatusCode.BadRequest, "Any object");
       }
       #endregion
   }

当我检查默认的xml媒体文件格式化程序，它看起来像...

我不知道如果添加手动会发生什么。可能需要自定义序列化。。

            config.Formatters.XmlFormatter
            .SupportedMediaTypes
            .Add(new System.Net.Http.Headers.MediaTypeHeaderValue("application/xliff+xml"));
