C# SOAP Authentication to non C# web service

E

Enda Manni

Hi,


I have a gSoap Web Service written using C++, it uses SOAP username and
password authentication.

I also have a C# form client consuming the web service, all this was working
fine until I added the authentication on the server, now I can not get the
client to authenticate. Can someone tell me how to add authentication info
to the SOAP message posted from the C# SOAP client.


here is some code I call to initilize the soap call from the C# form.

public partial class MyForm : Form
{
public MyForm()
{
InitializeComponent();

Service service = new Service();
}
...
...
...


I am using SOAP authentication, with a username and password. Here is the
soap request I would like to receive at the web service. It contains an
Authorization field.


<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope

Is there a way I can get this info into the C# client request?

Thanks,

I believe you posted this before, at least this time you answered the
question of whether or not you are using transport or message security.

Assuming you are using a web reference, you will want to set the
Credentials property on the proxy (in this case, your Service instance, I
believe) to an implementation of the ICredentials class. You would use the
NetwokCrediential instance, setting it to the username/password needed for
the website.

If you were using WCF, you would have to set up the wsHttpBinding to use
transport security, but this would only be allowed if you were using SSL
certificates (https), so that you could guarantee security (WCF won't allow
it otherwise).

Thanks

I added

service.Credentials = new System.Net.NetworkCredential("user", "pass");


but it still does not add the authorization to the SOAP header.


Here is my code:

public MyForm()
{
InitializeComponent();

Service service = new Service();

service.Credentials = new System.Net.NetworkCredential("user",
"pass");
}

I also added a web reference, it was difficult locating it as My web service
is a c++ gSoap web service, I specified the following string to find the web
reference.

http://127.0.0.1:8080/ns1.wsdl


Any more ideas.

Enda,

It's not supposed to add the authorization to the SOAP header. You
displayed this:

Host: localhost:8080
User-Agent: gSOAP/2.7
Content-Type: text/xml; charset=utf-8
Content-Length: 489
Connection: close
Authorization: Basic dXNlcjpwYXNz
SOAPAction: ""

Those are HTTP headers, and the Authorization field in that set of
headers is what is known as transport security. Setting the Credentials
property should set that Authorization field correctly.

If you want to use WS-Security spec, which will allow you to use
authentication/authorization on a ^message^ level, then you won't be able to
use a web reference here. You will have to use the Web Service Enhancements
from MS, or Windows Communications Foundation (WCF).

Mr. Arnold

If this is a SOAP XML Web service with SOAP Autentication, you can do a
http://url?wsdl in a broswer, and it produces the XML, then you should be
able to go to the .Net Command Prompt use the WSDL.exe utility to generate
a C# class that rspresent the SOAP and methods to consume said Web service
in a C# application.


I made the CS class with the WSDL.exe utility and used the class in code.

---------------------------------------
SAISUploadService.UploadDocumentService service =

new UploadDocumentService();

/*

* Set the header authentication/credential values;

*/

SAISUploadService.EDIServiceSOAPHeader authHeader =

new EDIServiceSOAPHeader();

authHeader.userName = SAISUploadUsername;

authHeader.passWord = SAISUploadPassword;

service.EDIServiceSOAPHeaderValue = authHeader;



string response =

service.UploadDocument (

SAISUploadCallerIdentifier,

GetDocumentType( Path.GetFileName( file ) ),

Path.GetFileName( file ),

GetFileData( file, dataFormat ),

dataFormat.ToString() );



CheckUploadResponse( response );
