问题
I have been given an old webservice .asmx to work with and although the code works fine in debug mode (VS play debug on local host) when I try and write a consumer app to pass the relevant SOAP request to get a response I cannot get it to work.
In .NET I get Status 415 Unsupported Media Type (never heard of that before) - tech asked me what media I was sending I said text as XML.
Here is all the code plus debug. I tried even writing an ASP classic version but get different errors depending on the SOAP version.
The webservice is on one server. I am trying to consume from my local machine and another server.
WebMethods are all in the .amsx file e.g
[WebMethod]
public string GetName(string ClientHash)
{
}
Running it all on localhost from VS in debug mode works a treat. Copied the files to a website in IIS setup for me called http://webservice.demo.co.uk
Has in it the following folder structure
webservice.demo.co.uk/http.demo/App_Data (empty) webservice.demo.co.uk/http.demo/bin -WebService.dll -WebService.pdb webservice.demo.co.uk/http.demo/properties -AssemblyInfo webservice.demo.co.uk/http.demo/ -WebService.asmx -Web.Config

These are the SOAP Request examples which come from hitting the debug button in VS 2010 and it running on local host on a port) - works fine e.g
POST /WebService.asmx HTTP/1.1
Host: localhost
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length
<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
<soap12:Body>
<GetName xmlns="http://tempuri.org/">
<ClientHash>string</ClientHash>
</GetName>
</soap12:Body>
</soap12:Envelope>
So I have just replaced the values for host and so on with my URL on my server where the web service is based
These are my ASP attempts
Soap 1.1 example ASP Classic
POST /WebService.asmx HTTP/1.1
Host: webservice.demo.co.uk
Content-Type: text/xml; charset=utf-8
Content-Length: length

So Root Element missing? What? And Server did not recognize the value of HTTP Header SOAPAction: /GetName.
So what am I doing wrong?
I know .asmx is old but I have taken over this project.
I just need a consumer app that can take what obviously works from VS on localhost but from PC to Server or Server to Server.
Why so many errors
And what is the Unsupported Media Type Error 415?
How can I fix it
