Llamando al servicio web ASP.NET ASMX desde jQuery

Question

Estoy tratando de llamar a un ASMX desde jQuery usando JSON y obtengo una respuesta de error SOAP.

¿Qué estoy haciendo mal ?!

Esta es mi llamada jQuery:

$.ajax({ 
      type: "POST", 
      url: '/Services/TeamPerson.asmx', 
      contentType: "application/json; charset=utf-8", 
      data: {'active':false, 'team_id':team_id, 'player_id':player_id}, 
      dataType: "json", 
      success: function(msg) { 
       alert(msg); 
      }, 
      error: function(xhr, msg) { alert(msg + '\n' + xhr.responseText); } 
      }); 

Esta es mi servicio web:

[WebService(Namespace = "http://tempuri.org/")] 
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] 
    [ToolboxItem(false)] 
    [ScriptService] 
    public class TeamPerson : WebService 
    { 
    [WebMethod] 
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)] 
    public void SetPlayerStatus(bool active, ulong team_id, ulong player_id) 
    { 
     // blah blah 
    } 
    } 

consigo un error de SOAP desagradable vuelta:

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

que puede golpear /Services/TeamPerson.asmx a través mi navegador y el método web funcionan bien. También tengo definido lo siguiente en web.config:

<httpHandlers> 
    <remove verb="*" path="*.asmx"/> 
    <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> 
    <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> 
    <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false"/> 
     <add verb="GET,HEAD,POST" path="TinyMCEHandler.aspx" type="Moxiecode.TinyMCE.Web.HttpHandler,Moxiecode.TinyMCE" /> 
    </httpHandlers> 
    <httpModules> 
    <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> 
    </httpModules> 

Answer 1

No está definiendo qué método para llamar al servicio. Intente cambiar su línea JQuery url: '/Services/TeamPerson.asmx', a url: '/Services/TeamPerson.asmx/SetPlayerStatus',

Answer 2

Quizás es el método web que falta en la URL, así como los parámetros.

var teamID = 123; 
var playerID = 456; 
var active = true; 
var webMethod = 'http://foo.net/TeamPerson.asmx/SetPlayerStatus' 
var parameters = "{'active':'" + active + 
       "','team_id':'" + teamID + 
       "','player_id':'" + playerID + "'}" 

$.ajax({ 
     type: "POST", 
     url: webMethod, 
     data: parameters, 
     contentType: "application/json; charset=utf-8", 
     dataType: "json", 
     success: function(msg) {  
       alert('all good'); 
     }, 
     error: function(e){ 
       alert('err'); 
     } 
});
