Web Services called directly not working

[tshad]

I am playing with web Services and soap and in the article I am using I
created a page:

***********************************************************************
<%@ WebService Language="c#" Class="FirstWebService" %>

using System;
using System.Web;
using System.Web.Services;

public class FirstWebService {

[WebMethod]
public string HelloWorld(string lcName) {
return "Hello World, " + lcName;
}

[WebMethod]
public decimal AddNumbers(decimal lnNumber1, decimal lnNumber2) {
return lnNumber1 + lnNumber2;
}

/*

[WebMethod]

public DateTime GetServerTime() {

return DateTime.Now;

} */
}
***********************************************************************

If I call http://localhost/FirstWebService.asmx, I get the services test
windows fine.

But if I do:
http://localhost/FirstWebService.asmx/AddNumbers?lnNumbers1=10&lnNumber2=20

I get an error:
***********************************************************************************
Request format is unrecognized.

about the error and where it originated in the code.

Hi Tom,

you can issue GET request only from the localhost by default for debugging
purposes only. Using GET requests in production environment is considered
insecure due to some XSS problems.
Still if you need to enable it use the following configuration in
web.config:

<webServices>
<protocols>
<add name="HttpGet"/>
</protocols>
</webServices>
