Impossible to use WSDL definition

StackOverflow https://stackoverflow.com/questions/669661

Question

A systematic breakdown of the problem follows. [Rewritten!]

The client code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

// This is a "sanitized" version of the real deal, of course. In reality I also require to
// sign all incomming and outgoing messages and com. over SSL. The basic model is the same
// though and the sanitized WSDL captures the problem in its minimal form.

namespace MissileDefenseSystem
{
    using MissileDefenseSystemServiceReference;

    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                var client = new TestPortTypeClient();
                var req = "just do it";
                Console.WriteLine("request>" + req + "<");
                var rsp = client.LaunchMissiles(req);
                Console.WriteLine("response>" + rsp + "<");
            }
            catch (Exception e)
            {
                Console.WriteLine("exception>" + e.Message + "<");
                Console.WriteLine(e.StackTrace);
            }
        }
    }
}

This is using the proxy code generated by SvcUtil.exe.

Now, I just tried using the WSDL.exe again. This works better, but now the next problem rears it's ugly head. The app.config for WCF is not used. So I need to configure the proxy class to use a certificate. For WCF I just say

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
              <binding name="TestBinding"/>
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="https://demo.blablablablablabla.com:123/Bla"
                binding="basicHttpBinding" bindingConfiguration="TestBinding"
                contract="MissileDefenseSystemServiceReference.TestPortType"
                name="TestPort">
                <identity>
                    <certificateReference storeLocation="CurrentUser" x509FindType="FindByThumbprint"
                        findValue="the thumbprint to be used" />
                </identity>
            </endpoint>
        </client>
    </system.serviceModel>
</configuration>

OK, now using a piece of code to provide signatures

    proxy.ClientCertificates.Add(cert);

This now almost works, except it can't decode the response.

Was it helpful?

Solution

It depends on what you expect to get. That is mirrored on how you define the wsdl. For example if you replace all "urn:Test" with java:bla.bla.bla.bla you get a simpler definition that just receives/returns strings.

If you still want to get 2 different request/response types, you can use this definition:

<?xml version="1.0" encoding="ISO-8859-1"?>
<definitions targetNamespace="java:bla.bla.bla.bla"
             xmlns="http://schemas.xmlsoap.org/wsdl/"
             xmlns:tns="java:bla.bla.bla.bla"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xmlns:xsd="http://www.w3.org/2001/XMLSchema"
             xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">
  <types>
    <schema targetNamespace='java:bla.bla.bla.bla' xmlns='http://www.w3.org/2001/XMLSchema'/>
  </types>
  <message name="AbortTestRequest">
    <part name="arg0" type="xsd:string"/>
  </message>
  <message name="AbortTestResponse">
    <part name="return" type="xsd:string"/>
  </message>
  <message name="LaunchTestRequest">
    <part name="arg0" type="xsd:string"/>
  </message>
  <message name="LaunchTestResponse">
    <part name="return" type="xsd:string"/>
  </message>
  <portType name="TestPortType">
    <operation name="LaunchMissiles">
      <input message="tns:LaunchTestRequest"/>
      <output message="tns:LaunchTestResponse"/>
    </operation>
    <operation name="AbortMission">
      <input message="tns:AbortTestRequest"/>
      <output message="tns:AbortTestResponse"/>
    </operation>
  </portType>
  <binding name="TestBinding" type="tns:TestPortType">
    <soap:binding style="rpc"  transport="http://schemas.xmlsoap.org/soap/http"/>
    <operation name="LaunchMissiles">
      <soap:operation soapAction="urn:LaunchMissiles"/>
      <input>
        <soap:body use="encoded" namespace='java:bla.bla.bla.bla/launch' encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
      </input>
      <output>
        <soap:body use="encoded" namespace='java:bla.bla.bla.bla/launch' encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
      </output>
    </operation>

      <input>
        <soap:body use="encoded" namespace='java:bla.bla.bla.bla/launch' encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
      </input>
      <output>
        <soap:body use="encoded" namespace='java:bla.bla.bla.bla/launch' encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
      </output>
    </operation>
  </binding>
  <service name="Test">
    <documentation>todo</documentation>
    <port name="TestPort" binding="tns:TestBinding">
      <soap:address location="https://demo.blablablablablabla.com:123/Bla"/>
    </port>
  </service>
</definitions>

Ps. as you seem to want request/response documents for all the operations/methods, you might want to switch completely to document style.

About comments not being able to make breaking changes. Changing namespaces or names of the message elements are breaking changes.

That said, if you are only interested in making it work (and don't care on the form of the classes you are getting) you can use the version you have. It doesn't matter the generated classes use LaunchMissileResponse for both methods, as the underlying XML will be the same (a TestResponse). Also for the calling code, remember you have a version that receives/sends simple strings:

public string AbortMission(string arg0)
