【问题描述】：

我正在尝试在以下函数的参数中传递 XLIFF 内容，但出现错误：

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

{ "message": "请求实体的媒体类型 'application/xml' 是此资源不支持。", "exceptionMessage": "否 MediaTypeFormatter 可用于从媒体类型为“application/xml”的内容。”、“exceptionType”： “System.Net.Http.UnsupportedMediaTypeException”，“stackTrace”：“在 System.Net.Http.HttpContentExtensions.ReadAsAsync[T](HttpContent 内容，类型类型，IEnumerable1 formatters, IFormatterLogger formatterLogger, CancellationToken cancellationToken)\r\n at System.Net.Http.HttpContentExtensions.ReadAsAsync(HttpContent content, Type type, IEnumerable1 格式化程序，IFormatterLogger formatterLogger， CancellationToken cancelToken)\r\n 在 System.Web.Http.ModelBinding.FormatterParameterBinding.ReadContentAsync（HttpRequestMessage 请求，类型类型，IEnumerable`1 格式化程序，IFormatterLogger formatterLogger, CancellationToken cancelToken)" }

我将如何解决这个问题？

完整代码如下：

// <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>
       /// Get or insert blog comments which is approved based on blogs
       /// </summary>
       /// <remarks> Get or insert blog comments which is approved based on blogs</remarks>
       /// <param name="message">The comment.</param>
       /// <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
   }

【问题讨论】：

您的请求内容类型是什么
xliff 格式为 application/xliff+xml 或 application/xliff+xml

标签： c# .net xml api asp.net-web-api

【解决方案1】：

当我检查默认的 xml 媒体文件格式化程序时，它看起来像..

不知道如果手动添加会怎么样。可能需要自定义序列化..

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