XML Post / Reply

[Andrew Robinson]

I need to make a web service call using an HTTPS POST. XML data is returned
in the body of the
HTTPS reply. What is the best way to do this with asp.net web services?

I am very comfortable in the world of asp.net and C# but have done nothing
with web services or XML. My first incling is to stream an XML document to
an HTTP Request object and then stream the response back to an XML document
but guessing there is a better way?

Thanks,
Sample data:

<Request StoreID="myStor eID" StoreKey="mySto reKey"
ApplicationID=" My Application Name Ver 1.0">
<CreditCardAuth orize>
<ReferenceNumbe r>1234</ReferenceNumber >
<TransactionAmo unt>1.00</TransactionAmou nt>
<AccountNumber> 411111111111111 1</AccountNumber>
<ExpirationMont h>12</ExpirationMonth >
<ExpirationYear >99</ExpirationYear>
</CreditCardAutho rize>
</Request>

HTTP request/response handling in the .NET framework is done with
HttpWebRequest/HttpWebResponse . Those expose streams (input or output
stream) and if you want to write or read XML then all XML APIs .NET have
overloads taking a stream (e.g. XmlWriter over a stream to post the XML
as part of a HTTP request body, XmlReader or XPathDocument or
XmlDocument over a stream to parse the XML in a HTTP response body).

If you web service follows standards like SOAP and WSDL then there are
additional tools to simply generate .NET proxy class code and make calls
to the web service by calling methods of a proxy object.

Our vendor has a SOAP / WSDL interface but the raw XML using POST is their
preferred interface (and they offer some additional functionality with it.).

Sounds like I was heading down the correct path based on your posting.
