He buscado por todas partes y cada respuesta que veo me dice que ponga lo siguiente en mi web.config:
<system.web>
<webServices>
<protocols>
<add name="HttpGet"/>
<add name="HttpPost"/>
</protocols>
</webServices>
</system.web>
Lo he hecho y sigo recibiendo el error.
Aquí es el guión de mi página web:
<script>
$(function() {
$('#btn').click(
function() {
CallHome();
}
);
});
function CallHome() {
$.ajax({
type: "POST",
url: "HelloWorld.asmx/HelloWorld",
dataType: "xml",
data: "{}",
contentType: "xml",
success: function(data) {
alert(data);
}
});
}
</script>
Y el WebService.vb es:
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
Imports System.Web.Script.Services
<System.Web.Script.Services.ScriptService()> _
<System.Web.Services.WebService(Namespace:="http://tempuri.org/")> _
<System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<ToolboxItem(False)> _
Public Class HelloWorld
Inherits System.Web.Services.WebService
<WebMethod()> _
Public Function HelloWorld() As String
Return "Hello World"
End Function
End Class
He creado un nuevo proyecto web de la marca a recortar mi ejemplo al mínimo. ¡En algún lugar estoy jodiendo! ¿Puede usted ayudar?
GRACIAS!
ACTUALIZACIÓN: Tipo de nuevo a Fiddler ... pero aquí están las cabeceras del mensaje: ajax

No estoy seguro si eso ayuda ...

por favor incluyen el error completo. –
IIS 7? Si es así, la configuración de http debe establecerse en la sección de web.config –
bien ... He estado tratando de descubrir cómo agregar esto a la configuración de la sección system.webserver y no puedo encontrar eso. Cuando los agrego obtengo un error. ¡Gracias! – Dave
