c# - 无法使用 WSDL 定义

Question

问题的系统分解如下。 [重写!]

客户端代码

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);
            }
        }
    }

这是使用 SvcUtil.exe 生成的代理代码。

现在，我再次尝试使用 WSDL.exe。这样效果更好，但现在下一个问题又出现了。不使用 WCF 的 app.config。所以我需要配置代理类来使用证书。对于 WCF，我只是说

<?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，现在用一段代码提供签名

    proxy.ClientCertificates.Add(cert);

这现在几乎可以工作了，除了它不能解码响应。

Answer 1

这取决于您期望得到什么。这反射(reflect)了您如何定义 wsdl。例如，如果您将所有“urn:Test”替换为 java:bla.bla.bla.bla，您会得到一个更简单的定义，它只接收/返回字符串。

如果你仍然想获得 2 种不同的请求/响应类型，你可以使用这个定义:

<?xml version="1.0" encoding="ISO-8859-1"?>

             xmlns="http://schemas.xmlsoap.org/wsdl/"

    <operation name="LaunchMissiles">

      <input>

附言。由于您似乎想要所有操作/方法的请求/响应文档，您可能想要完全切换到文档样式。

关于无法进行重大更改的评论。更改命名空间或消息元素的名称是重大更改。

就是说，如果您只对让它工作感兴趣(而不关心您获得的类的形式)，您可以使用您拥有的版本。生成的类对这两种方法使用 LaunchMissileResponse 并不重要，因为底层 XML 是相同的(一个 TestResponse)。同样对于调用代码，请记住您有一个接收/发送简单字符串的版本:

public string AbortMission(string arg0)
