我的问题是我在ASP.net上有一个web服务,它返回一个JSON字符串对象(没有XML)。但是,当我打电话给网络方法时,我有这个:
<string xmlns="https://www.puzzlebooks.com.ar">
{"Tipo":null,"Anio":0,"Mes":null,"CuentaContable":null,"Total":0,"OId":0}
</string>
在客户端,消息错误如下:Unexpected token < in json at position 0
我期待这个JSON:
{"Tipo":null,"Anio":0,"Mes":null,"CuentaContable":null,"Total": 0,"OId": 0}
纯粹的JSON
这是我的网络服务代码:
[WebMethod(EnableSession = true)]
[System.Web.Script.Services.ScriptMethod(ResponseFormat = System.Web.Script.Services.ResponseFormat.Json) ]
public string AcumuladoTotalCompraVenta_MesActual()
{
try
{
ModeloDeClases.Dominio.EstadisticaCompraVenta totalAcumulado = null;
totalAcumulado = RepositorioServicios.RepositoryServices.getInstance().getEstadisticasServices().CompraVenta_TotalAcumuladoDelMesActual(23);
if (totalAcumulado == null)
totalAcumulado = new ModeloDeClases.Dominio.EstadisticaCompraVenta();
string queHAY = new JavaScriptSerializer().Serialize(totalAcumulado);
// return totalAcumulado;
return queHAY;
}
catch (Exception ex)
{
this.Error(ex.Message);
return null;
}
}
来自客户端(aspx页面)的代码是:
<script type="text/javascript">
$(function ()
{
$.ajax
({
type: "POST",
dataType: "json",
contentType: "application/json",
url: "../webServices/wsEstadisticas.asmx/AcumuladoTotalCompraVenta_MesActual",
data: "{}",
success: chartAcumuladoComprasVentas_MesActual,
error: function (request, status, error)
{
alert('NOP!');
alert(request.statusText);
alert(error);
alert(request.toString());
}
});
})
function chartAcumuladoComprasVentas_MesActual()
{
alert('IT S WORK!');
}
</script>
我在这个网站上搜索同样的问题但是没有用。用于JSON的Newtonsoft库对我来说不起作用,因为当我不使用时,我得到了相同的结果。

我在这里找到答案: asp.net asmx web service returning xml instead of json
this.Context.Response.ContentType = "application/json; charset=utf-8";
this.Context.Response.Write(serial.Serialize(city));
