Webapi cordova服务器响应状态为500

Question

我有两个不同领域的项目。

Apache cordova和webapi ...

我发布请求时出现内部500错误。问题可能出在webapi配置中。

    //global.asax.cs
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        GlobalConfiguration.Configure(WebApiConfig.Register);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
        GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
        GlobalConfiguration.Configuration.Formatters.Remove(GlobalConfiguration.Configuration.Formatters.XmlFormatter);

    }
    protected void Application_BeginRequest()
    {
        if (Request.Headers.AllKeys.Contains("Origin") && Request.HttpMethod == "OPTIONS")
        {
            Response.Flush();
        }
    }

    //script.js
    $(document).ready(function () {
        $("#datasubmit").click(function () {
            var data = $("#data").val();
            //alert(aracplaka);
            $.ajax({
                type: "post",
                dataType: 'json',  
                url: "http://10.16.0.22:88/api/arac",
                data: data,
                success: alert("başarılı"),
                error: function () {
                    alert("hata")
                }
            })
        });
    });
