WebService Authentication

Former Member — Mon, 19 Oct 2009 18:23:59 GMT

Hello All,

I have created a WebService on SAP ECC 6, and would like to use it on my .NET program. (C# CSHARP language).

But, How can I inform the user and password? How can I authenticate on SAP ECC?

A piece of code:

WebReference.zwservice zwservice = new WebReference.zwservice();

WebReference.zwsmethodo zwsmethodo = new WebReference.zwsmethodo();

zwsmethodo.I_ENTRADA = "1";

WebReference.zwsmethodoResponse zresp = zwservice.zwsmethodo(zwsmethodo);

Console.WriteLine("Resp ", zresp.E_NOME);

Thanks!

Marcel

Hello All,

I found the solution.

In Visual C# 2008 Express Edition, was necessary to override the method System.Net.WebRequest GetWebRequest, and inform the username and password.

Jut insert this code in the partial class!

protected override System.Net.WebRequest GetWebRequest(Uri uri)

{

System.Net.HttpWebRequest request = (System.Net.HttpWebRequest)base.GetWebRequest(uri);

request.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new System.Text.ASCIIEncoding().GetBytes("USERNAME" + ":" + "PASSWORD")));

return request;

}

Regards,

Marcel
