如何解决错误HTTP 404.15？

Question

当我尝试在ajax中进行请求时，会出现此错误：

The Request Filtering module is configured to deny a request when the query string is too long.（“请求过滤”模块配置在查询字符串过长时拒绝请求。）

有人有解决此问题的方案吗？

下面是ajax和控制器中的一个例子：

$.ajax({
        type: "GET",
        url: "@Url.Action("nuevaTarjetaCapacitacion", "TarjetaCapacitacion")",
        scriptCharset: "iso-8859-1",
        dataType: "json",
        contentType: "application/json; charset=iso-8859-1",
        data: {
            TarjetaCapacitacionId: $("#TarjetaCapacitacionId").val(),
            NombreCurso: $("#NombreCurso").val(),
            Descripcion: $("#Descripcion").val(),
            FechaInicio: $("#FechaInicio").val(),
            FechaFin: $("#FechaFin").val(),
            //TipoCurso: $("#TipoCurso").val(),
            Departamentos: tarjetaCapacitacion.Departamentos.toString(),
            Puestos: tarjetaCapacitacion.Puestos.toString(),
            Personal: tarjetaCapacitacion.Personal.toString(),
            Instructores: tarjetaCapacitacion.Instructores.toString(),
            InstructoresExternos: JSON.stringify(tarjetaCapacitacion.InstructoresExternos),
            Documentos: tarjetaCapacitacion.Documentos.toString(),
            AprobacionId: $("#AprobacionId").val()
        }


public JsonObject nuevaTarjetaCapacitacion(string NombreCurso, string Descripcion, string FechaInicio, string FechaFin, /*string TipoCurso,*/ string Departamentos, string Puestos, string Personal, string Instructores, string InstructoresExternos, string Documentos, int? AprobacionId)
    {
    }

Answer 1

You could use a POST instead of a GET. That way the data will in the request body of the HTTP request and not in the query string.

Check here: https://forums.asp.net/t/2024846.aspx?HTTP+Error+404+15+query+url+too+long

The request filtering module is configured to deny a request where the query string is too long. Looking at the Requested URL I see this:

It seems like a redirect loop somewhere. I suspect something in the IIS Express config but I have no idea what it could be (it's basically the

$.ajax({
            type: "GET",
            url: "@Url.Action("nuevaTarjetaCapacitacion", "TarjetaCapacitacion")",
            scriptCharset: "iso-8859-1",
            dataType: "json",
            contentType: "application/json; charset=iso-8859-1",
            data: {
                TarjetaCapacitacionId: $("#TarjetaCapacitacionId").val(),
                NombreCurso: $("#NombreCurso").val(),
                Descripcion: $("#Descripcion").val(),
                FechaInicio: $("#FechaInicio").val(),
                FechaFin: $("#FechaFin").val(),
                //TipoCurso: $("#TipoCurso").val(),
                Departamentos: tarjetaCapacitacion.Departamentos.toString(),
                Puestos: tarjetaCapacitacion.Puestos.toString(),
                Personal: tarjetaCapacitacion.Personal.toString(),
                Instructores: tarjetaCapacitacion.Instructores.toString(),
                InstructoresExternos: JSON.stringify(tarjetaCapacitacion.InstructoresExternos),
                Documentos: tarjetaCapacitacion.Documentos.toString(),
                AprobacionId: $("#AprobacionId").val()
                   }
               });

 public JsonResult nuevaTarjetaCapacitacion(string NombreCurso, string Descripcion, string FechaInicio, string FechaFin, /*string TipoCurso,*/ string Departamentos, string Puestos, string Personal, string Instructores, string InstructoresExternos, string Documentos, int? AprobacionId)
        {
            Json("", JsonRequestBehavior.AllowGet)
        }

You should use return Json("", JsonRequestBehavior.AllowGet) instead of return Json("") otherwise you will get error "This request has been blocked because sensitive information could be disclosed to third party web sites when this is used in a GET request. To allow GET requests, set JsonRequestBehavior to AllowGet."
