WebService Client Adding Soap Header

Question

User1018509147 posted

I am new to .NET and webservices. I am trying to call a webservice written in Java. This is a two stage proces. The first is retrieving a <nonce> value. The second stage is to add the retrieved <nonce> value (which is series of numbers/chars. e.g 1234gh563432134e) to the Soap Header tag <Authentication>. The messgae should look as follows:

SOAP-ENV:Envelope
SOAP-ENV:encodingStyle=http://schemas.xmlsoap.org/soap/encoding/
xmlns:SOAP-ENV=http://schemas.xmlsoap.org/soap/envelope/
xmlns:xsd=http://www.w3.org/2001/XMLSchema
xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance
xmlns:SOAP-ENC=http://schemas.xmlsoap.org/soap/encoding/
xmlns:si="http://soapinterop.org/xsd"><SOAP-ENV:Header><authentication>
 <nonce>13b9b5c6fffad00010de8d65b9647e0a</nonce>
 <ident>test</ident>
 <auth>c219245a06ba7b918c15c6b5b9e3a7b5</auth>
</authentication>

I am using a proxy class to invoke the required method, it is with this method; woningzoekendeupdate that i am trying to figure out how to add the authentication info to the SoapHeader:

[System.Web.Services.WebServiceBindingAttribute(Name = "bindingName", Namespace = "")]
public class SoapProxy : System.Web.Services.Protocols.SoapHttpClientProtocol
{
 public SoapProxy()
 {
  //Webservice location
  this.Url = "#";
 }

 [System.Web.Services.Protocols.SoapDocumentMethodAttribute("woningzoekendeupdate", RequestNamespace = "#", Use = System.Web.Services.Description.SoapBindingUse.Default, ParameterStyle =  System.Web.Services.Protocols.SoapParameterStyle.Default)]
 [return: System.Xml.Serialization.XmlElement("contractaanbieding", Namespace = "#", DataType = "string")]
 public string woningzoekendeupdate(object woningzoekendeupdate)
 {
  object[] results = this.Invoke("woningzoekendeupdate", new object[] { "dummy_parameter" });
  return ((string)(results[0]));
 }
}

Can anybody explain how to do this?

Hi,
PLS refer to this article about how to use custom soaphead in .net:

Hope it helps.

Thanks for your reply, I have been able to add a custom header using the following code:

[System.Web.Services.Protocols.SoapDocumentMethod(Action = "woningzoekendeupdate", Use = System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Bare)]
[System.Web.Services.Protocols.SoapHeaderAttribute("AuthenticationHeader")]
[return: System.Xml.Serialization.XmlElement("contractaanbieding")]
public string woningzoekendeupdate([XmlElement(ElementName = "namesp1woningzoekendeupdate", IsNullable = true)] XmlDocument aanbieding)
{
 object[] results = this.Invoke("woningzoekendeupdate", new object[] { aanbieding });
 return ((string)(results[0]));
}

I have written a "get set" method in the same class as where the above method is written in to access "AuthenticationHeader":

public authentication AuthenticationHeader
{
 get
 {
   return this._authenticationHeader;
 }
 set
 {
   this._authenticationHeader = value;
 }
}

The authentication class has properties for the header which are set on initialisation of the class (so: new authentication). This means that before the header can actually be used the class needs to be initiated. The code isnt the most efficient one but for now it works I am planning to make the code cleaner and more logical. 

Oh and before I forget this is the eseential part of the authentication class:

[System.SerializableAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace = http://xml.nccw.nl/xml/soap-auth/)]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "http://xml.nccw.nl/xml/soap-auth/", IsNullable = false)]

public partial class authentication : System.Web.Services.Protocols.SoapHeader
{
 //Put you public get set code here for you properties. String type can be used the essential header formatting for your SOAP header part is done by:
 -- System.Web.Services.Protocols.SoapHeader

I am now trying to figure out who to add a prefix to my SOAP request. Currently I am sending a XML document enclosed in the element "woningzoekendupdate". I am trying to make that element into: namesp1:woningzoekendeupdate. If anyone has an idea on how to accomplish that.. I am all ears.

Cheers

Hi,

Did you ever solve the problem with the namespace prefixes? I'm having the exact same problem right now.
