Custom SOAP headers

D

DonTomasso

I'm trying to modify my soap headers before making a call to a web service.
I am using an IClientMessageInspector class and adding a single header works
fine, but I want to add a more complex object into the header.

The resulting SOAP xml is supposed to look something like this:

<soapenv:Header>
<myroot>
<vala>somevalue</vala>
<valb>someothervalue</valb>
<valc>a third value</valc>
</myroot>
</soapenv:Header>

I have no clue how to do this.... MessageHeader has no "addNode" or nothing...

I'm also currious on how to extract the same type of information in the
resulting message.

Anyone?

Thanx
Thomas

I solved it!
And it was no fun doing so.... This methology must have been developed by
someone who is totally instituniolized.

I won't show the entire thing, would take too much space, the code for
modifying the SOAP headers should really be something like;
client.envelope.headers.add(...), but it's not. If you need to modify the
headers do a Google for "IClientMessageInspector" and you'll find what you
need.


First off create a class that represents your header:

[DataContract(Namespace = "http://mynamespace.com", Name =
"MyHeaderClass")]
public class MyHeaderClass
{
private string someValue;

[DataMember]
public string SomeValue
{
get { return someValue; }
set { someValue= value; }
}
}

In the BeforeSendRequest(...) method of your ClientMessageInspector add code
similar to the code bellow:


MessageHeader<MyHeaderClass> header = new MessageHeader<MyHeaderClass>();

MyHeaderClass myHeader = new MyHeaderClass();
myHeader.SomeValue = "My value";

header.Content = myHeader;
header.Actor = "Anyone";

System.ServiceModel.Channels.MessageHeader unTypedHeader =
header.GetUntypedHeader("MyHeaders", ns);

request.Headers.Add(unTypedHeader);

This will give you a SOAP header that looks something like:

<MyHeaders s:actor="Anyone" xmlns="http://mynamespace.com">
<SomeValue>My Value</SomeValue>
</MyHeaders>

Custom SOAP headers was a joke in .NET 2.0, and is even worse in 3.5 / wcf.

Now I need to figure out how to extract the outbound headers as well....
