Adding SOAP headers to ASMX web service message

01-02-2009 5:48 PM |

How to add User Name and password to SOAP ASMX webservice call message header ?

I tried MSDN sample from

http://msdn.microsoft.com/en-us/library/8728chd5(VS.80).aspx

class MyHeader : SoapHeader

{

public string UserName;public string Password;

}

but got error since SoapHeader class is not defined.

How to fix ? Can we use WCF OperationContext with ASMX web services or any other idea ?

Andrus.

Hi Andrus,

you have to use HttpContext, the following example permits to retrieve the header "Username":

[WebMethod]

public string Hello(String name)

{

string Username = String.Empty;

try

{

if (HttpContext.Current.Request.ServerVariables["HTTP_SOAPACTION"] != null)

{

// Load the body of the HTTP message

// into an XML document.

Stream HttpStream = HttpContext.Current.Request.InputStream;

HttpStream.Position = 0;

XmlDocument dom = new XmlDocument();

dom.Load(HttpStream);

// Bind to the Authentication header.

Username =

dom.GetElementsByTagName("Username").Item(0).InnerText;

}

catch { }

return "Hello " + Username;

}

Thanks, Davide

Davide,

Thank you.

You showed a way to retrieve message headers.

I asked for a way to add username/password to message from SL client application.

Btw. HttpContex class is not available in sl runtime.

Hi Andrus,

for the client just use the code available here (solution SilverlightHeaders):

http://code.msdn.microsoft.com/Project/Download/FileDownload.aspx?ProjectName=silverlightws&DownloadId=3473

modify the SilverlightIpAddressMessageInspector class adding your personalized Headers:

public object BeforeSendRequest(ref Message request, IClientChannel channel)

{

request.Headers.Add(MessageHeader.CreateHeader("Username", "", "Davide"));

return null;

}

Now insert a new asmx service in your web project to retrieve the Headers using the code I've posted in the previous post (here you have to use HttpContext).

Please let me know if the code works, otherwise I can send you a complete VS solution.

Thanks, Davide

David, your solution works very well except for one thing: what if the asmx web service is deployed on a production machine and you are not able to upgrade the server code to retrieve the headers from the httpcontext?
