c# - WCF SOAP 调用 HTTP header 的内容类型中缺少操作

Question

几天来，我一直在调查为什么我的 SOAP 请求根据我的供应商不正确，以及如何更改它。

我按照以下步骤创建了我的 SOAP 客户端:

• 将服务引用添加到我的项目中。服务的wsdl是:

    <?xml version="1.0" encoding="utf-8"?>

      </wsdl:port>
     </wsdl:service>
    </wsdl:definitions>

这为我创建了代理类。

• 接下来我稍微调整了我的 app.config，强制它使用 soap1.2(所以我删除了 soap1.1 条目，因为我遇到了问题)

  <?xml version="1.0"?>
  <configuration>
      <system.serviceModel>
          <bindings>
              <customBinding>
                  <binding name="vz801802Soap12">
                      <textMessageEncoding messageVersion="Soap12" />
                      <httpsTransport requireClientCertificate="true" />
                  </binding>
              </customBinding>
          </bindings>
          <client>
              <endpoint address="https://acccovwebservice.vecozo.nl/v1/VZ801802.svc"
                  binding="customBinding" bindingConfiguration="vz801802Soap12"
                  contract="COV_VZ801802.vz801802Service" name="vz801802Soap12" />
          </client>
      </system.serviceModel>
  </configuration>
  

• 实例化和调用webservice的代码是:
  

  WSHttpBinding serviceBinding = new WSHttpBinding(SecurityMode.Transport);
  serviceBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;
  serviceBinding.ReceiveTimeout = new TimeSpan(0, 0, 120);<br/>
  EndpointAddress endpointAddress = new EndpointAddress(Bericht.Url);
  COV_VZ801802.vz801802ServiceClient VZ801_Client = new COV_VZ801802.vz801802ServiceClient(serviceBinding, endpointAddress);<br/>
  if (Bericht.Certificaat != null && Bericht.Certificaat != "")
  {
      X509Certificate2 x509_2 = new X509Certificate2(Bericht.Certificaat);
      VZ801_Client.ClientCredentials.ClientCertificate.Certificate = x509_2;
  }<br/>
  COV_VZ801802.ControleerRequestType VZ801_Request = new COV_VZ801802.ControleerRequestType();<br/>
  // Here I fill request with data<br/>
  COV_VZ801802.ControleerResponseType VZ801_Reponse = VZ801_Client.Controleer(VZ801_Request);
  

• 使用 Fiddler 检查消息时，我看到以下内容:

运行程序时，出现异常，告诉我:

The message with Action '' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).

供应商告诉我他在这条消息中看到了两个问题:

1. 标题的内容类型中没有定义任何操作。内容类型应为 application/soap+xml;charset=UTF-8;action="http://schemas.vecozo.nl/VZ801802/v1/Controleer"
2. MustUnderstand(在 Action 和 To 标签中)的两个值都应该是 0 而不是 1

我一直在搜索各种地方，尝试自定义 header 等等，但我还没有找到解决这些问题的方法。

有人可以帮我解决这个问题吗？？？我非常绝望，因为我需要在 6 月 1 日之前解决这个问题。

顺便说一句，我正在使用 .NET 4.0顺便说一句，我正在使用 Visual Studio Express 2012 for Windows Desktop 来编辑我的项目

    }

Answer 1

我认为你的问题与:

Next I tweaked my app.config a little, to force it to use soap1.2

当您在代码中创建客户端时，您已经指定了 WSHttpBinding，这在默认情况下将发送 soap12 请求。

我认为您对绑定(bind)的调整(添加自定义绑定(bind))以某种方式覆盖了 wsHttpBinding 的默认行为，即将 soap 操作放入内容类型 header 值中。

如果您在不进行调整的情况下使用生成的配置文件会怎样？

编辑

我的新理论是:您在代码中创建客户端的方式导致 WCF 忽略配置文件中定义的绑定(bind)。

您应该通过传入配置文件中定义的客户端绑定(bind)名称来创建绑定(bind)实例，例如:

var serviceBinding = new WSHttpBinding("vz801802Soap12");

或者设置Binding.MessageVersion property也在代码中。

编辑

我当时不明白的是，为什么您要通过传入绑定(bind)在代码中初始化客户端。您可以只创建客户端并在配置文件中传入客户端端点的名称吗？应该没有理由开始在代码中创建东西，因为当您添加服务引用时，所有必要的东西都应该由 visual studio 放入配置中
