以编程方式定义具有行为的 WCF 端点

Question

谁能告诉我如何以编程方式创建具有端点行为的 WSHttpBindings？

这是从 WCF 添加服务引用到 6 个 WebServices 生成的，我手动编辑了这些 WebServices 以添加行为，以便所有端点都使用相同的行为。

<system.serviceModel>
  <behaviors>
    <endpointBehaviors>
      <behavior name="epBehaviour">
        <clientCredentials>
          <clientCertificate findValue="This is my TEST Cert" storeLocation="LocalMachine" x509FindType="FindBySubjectName" storeName="My" />
        </clientCredentials>
      </behavior>
    </endpointBehaviors>
  </behaviors>
  <bindings>
    <wsHttpBinding>
      <binding name="WSHttpBinding_IQuote" messageEncoding="Mtom">
        <security mode="TransportWithMessageCredential">
          <transport clientCredentialType="None" />
          <message clientCredentialType="Certificate" establishSecurityContext="false" />
        </security>
      </binding>
      <binding name="WSHttpBinding_ICommit" messageEncoding="Mtom">
        <security mode="TransportWithMessageCredential">
          <transport clientCredentialType="None" />
          <message clientCredentialType="Certificate" establishSecurityContext="false" />
        </security>
      </binding>
      <binding name="WSHttpBinding_IRetrieve" messageEncoding="Mtom">
        <security mode="TransportWithMessageCredential">
          <transport clientCredentialType="None" />
          <message clientCredentialType="Certificate" establishSecurityContext="false" />
        </security>
      </binding>
      <binding name="WSHttpBinding_IInfo" messageEncoding="Mtom">
        <security mode="TransportWithMessageCredential">
          <transport clientCredentialType="None" />
          <message clientCredentialType="Certificate" establishSecurityContext="false" />
        </security>
      </binding>
      <binding name="WSHttpBinding_IPurge" messageEncoding="Mtom">
        <security mode="TransportWithMessageCredential">
          <transport clientCredentialType="None" />
          <message clientCredentialType="Certificate" establishSecurityContext="false" />
        </security>
      </binding>
      <binding name="WSHttpBinding_ISearch" messageEncoding="Mtom">
        <security mode="TransportWithMessageCredential">
          <transport clientCredentialType="None" />
          <message clientCredentialType="Certificate" establishSecurityContext="false" />
        </security>
      </binding>
    </wsHttpBinding>
  </bindings>
  <client>
    <endpoint address="https://my.service.com/WCFServices/Info.svc" behaviorConfiguration="epBehaviour" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IInfo" contract="InfoWcfWS.IInfo" name="WSHttpBinding_IInfo" />
    <endpoint address="https://my.service.com/WCFServices/Quote.svc" behaviorConfiguration="epBehaviour" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IQuote" contract="QuoteWcfWS.IQuote" name="WSHttpBinding_IQuote" />
    <endpoint address="https://my.service.com/WCFServices/Commit.svc" behaviorConfiguration="epBehaviour" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_ICommit" contract="CommitWcfWS.ICommit" name="WSHttpBinding_ICommit" />
    <endpoint address="https://my.service.com/WCFServices/Retrieve.svc" behaviorConfiguration="epBehaviour" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IRetrieve" contract="RetrieveWcfWS.IRetrieve" name="WSHttpBinding_IRetrieve" />
    <endpoint address="https://my.service.com/WCFServices/Purge.svc" behaviorConfiguration="epBehaviour" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IPurge" contract="PurgeWcfWS.IPurge" name="WSHttpBinding_IPurge" />
    <endpoint address="https://my.service.com/WCFServices/Search.svc" behaviorConfiguration="epBehaviour" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_ISearch" contract="SearchWcfWS.ISearch" name="WSHttpBinding_ISearch" />
  </client>
</system.serviceModel>

目前，通过“添加服务”生成的代理并添加在端点中作为行为配置引用的行为“epBehaviour”，我可以调用端点。

现在，我的下一步是将行为部分和 URL 定义为配置（可能位于 web.config 中），以便我可以为暂存和生产使用不同的配置。

因此，我的示例暂存配置的 URL 定义如下

<appSettings>
  <add key="ServiceUrl.Tls12.Quote" value="https://my.service.com/WCFServices/Quote.svc" />
  <add key="ServiceUrl.Tls12.Commit" value="https://my.service.com/WCFServices/Commit.svc" />
  <add key="ServiceUrl.Tls12.Retrieve" value="https://my.service.com/WCFServices/Retrieve.svc" />
  <add key="ServiceUrl.Tls12.Info" value="https://my.service.com/WCFServices/Info.svc" />
  <add key="ServiceUrl.Tls12.Purge" value="https://my.service.com/WCFServices/Purge.svc" />
  <add key="ServiceUrl.Tls12.Search" value="https://my.service.com/WCFServices/Search.svc" />
</appSettings>

因此，如果我使用“Info”WebService，我的代码应该类似于

//Code is missing how to define all the specifics like behaviours.
WSHttpBinding binding = new WSHttpBinding();
                EndpointAddress endpoint = new EndpointAddress(new Uri(ConfigurationManager.AppSettings["ServiceUrl.Tls12.Info"]));
             InfoWcfWS.InfoClient proxyNew = new InfoWcfWS.InfoClient(binding, endpoint);

总之，给定“添加服务”后生成的配置，为了生成我的代理类，我想删除 VS 生成的所有配置并定义我自己的配置来保存 URL；其他所有内容（如端点 URI、行为等）都应该以编程方式实例化。

谢谢

您必须从System.ServiceModel.Description命名空间创建所需行为的实例，或者自己创建它们，然后将它们添加到ChannelFactory.

对于您的示例，您可以ChannelFactory为您想要的界面和您喜欢的任何绑定创建一个。然后，您实例化一个ClientCredentials行为，配置您需要的任何设置并将其添加到EndPointBehaviorsChannelFactory 中。然后，您就可以创建一个客户端通道，它将为您提供一个实现服务接口的对象。您可以使用与生成的客户端类似的内容。

// binding
var binding = new WSHttpBinding();
// using System.ServiceModel
var channelFactory = new ChannelFactory<InfoWcfWS.IInfo>(binding);
// using System.ServiceModel.Description
var endpointClientbehavior = new ClientCredentials();
endpointClientbehavior.ClientCertificate
    .SetCertificate(
    "This is my TEST Cert", 
    StoreLocation.LocalMachine, 
    StoreName.My);
// add the behavior to the endpoint
channelFactory.Endpoint.EndpointBehaviors.Add(endpointClientbehavior);

// done configuring;
channelFactory.Open();
var endpoint = new EndpointAddress(
    new Uri(ConfigurationManager.AppSettings["ServiceUrl.Tls12.Info"]));
// create the clientChannel
var client = channelFactory.CreateChannel(endpoint);
client.Open();
// client implements the operations on InfoWcfWS.IInfo
