ASP.NET Calling WebMethod with jQuery AJAX "401 (Unauthorized)"

Been stuck with this for hours



{"Message":"Authentication failed.","StackTrace":null,"ExceptionType":"System.InvalidOperationException"}


I'm trying to call this WebMethod in my ASP.Net Webform


[WebMethod]
public static string GetClients(string searchTerm, int pageIndex)
{
string query = "[GetClients_Pager]";
SqlCommand cmd = new SqlCommand(query);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@SearchTerm", searchTerm);
cmd.Parameters.AddWithValue("@PageIndex", pageIndex);
cmd.Parameters.AddWithValue("@PageSize", PageSize);
cmd.Parameters.Add("@RecordCount", SqlDbType.Int, 4).Direction = ParameterDirection.Output;
return GetData(cmd, pageIndex).GetXml();
}


From this jquery.ajax


function GetClients(pageIndex) {
$.ajax({
type: "POST",
url: "ConsultaPedidos.aspx/GetClients",
data: '{searchTerm: "' + SearchTerm() + '", pageIndex: ' + pageIndex + '}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: OnSuccess,
failure: function (response) {
alert(response.d);
},
error: function (response) {
alert(response.d);
}
});
}


But I always get this error:


POST
http://localhost:64365/ConsultaPedidos.aspx/GetClients
401
(Unauthorized)



Weird thing is that this used to work until I start authenticating users



<system.web>
...
<authentication mode="Forms">
<forms loginUrl="~/Account/Login" timeout="2880" defaultUrl="/Dashboard" />
</authentication>
<authorization>
<deny users="?" />
</authorization>
...
</system.web>


Any ideas?

Answer

Problem solved

This was driving me crazy.

Inside ~/App_Start/RouteConfig.cs change:

settings.AutoRedirectMode = RedirectMode.Permanent;

To:

settings.AutoRedirectMode = RedirectMode.Off;

(Or just comment the line)

Also if friendly URLs are enabled you need to change

url: "ConsultaPedidos.aspx/GetClients",

To:

url: '<%= ResolveUrl("ConsultaPedidos.aspx/GetClients") %>',

Hope this help somebody else
