Creating a consumer of a Web Service WSDL/SOAP
- by Azzi
I am attempting to write a Windows Desktop App (using WCF) that is a consumer of a web service.
The application:
Sends a SOAP message to a British Government Server to get an authentication token based on the arugments passed
Retrieves a response from that server in the form of a string which contains the authentication token.
I have a template of the SOAP message from the British Government, and a WSDL file for the service.
What I have tried
Add a service reference using the WSDL file. I received the following error: URI formats are not supported.
Add a Web Reference using the URL of the service. I received the following error: The request failed with HTTP status 405: Method Not Allowed.
Send the SOAP request using a POST. The Call to GetResponse() threw a 500 External Server Error.
NOTE: I am using VS 2005
