c# - 在 C# 中以编程方式创建 WCF 客户端的 header (wsse) 部分

Question

如何以编程方式在 C# 中创建 app.config 的以下服务设置部分:

    <client>
  <endpoint address="https://someServiceUrl"
      binding="basicHttpBinding" bindingConfiguration="Contact"
      contract="ServiceReference.PostingWebService" name="PostingWebServicePort">
    <headers>
      <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
        <wsse:UsernameToken>
          <wsse:Username>someusername</wsse:Username>
          <wsse:Password Type='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText'>somepassword</wsse:Password>
        </wsse:UsernameToken>
      </wsse:Security>
    </headers>
  </endpoint>
</client>

我已设法从 C# 生成绑定(bind)部分(上面未包含)和端点部分。我无法创建标题部分。

出现的错误是:(这是因为当我从 C# 生成所有内容时，我没有 header 部分)

此服务需要 <wsse:Security> ，缺少。

header 部分很重要，就好像我将其从配置中排除并使用配置运行代码一样，它也会出现上述错误。

我不想使用 web.config/app.config。我必须从 C# 运行所有东西。 (上面的 app.config 工作正常，但我想通过 C# 做同样的事情)

注意:以下更新基于以下提供的解决方案，请仔细阅读以下解决方案的评论，以便更好地理解

更新 1:(首先以编程方式使用 BasicHttpBinding)

BasicHttpBinding binding = new BasicHttpBinding();
        binding.Name = "Contact";
        binding.CloseTimeout = TimeSpan.FromMinutes(1);
        binding.OpenTimeout = TimeSpan.FromMinutes(1);
        binding.ReceiveTimeout = TimeSpan.FromMinutes(10);
        binding.SendTimeout = TimeSpan.FromMinutes(1);
        binding.AllowCookies = false;
        binding.BypassProxyOnLocal = false;
        binding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
        binding.MaxBufferSize = 524288;
        binding.MaxBufferPoolSize = 524288;
        binding.MaxReceivedMessageSize = 524288;
        binding.MessageEncoding = WSMessageEncoding.Text;
        binding.TextEncoding = System.Text.Encoding.UTF8;
        binding.TransferMode = TransferMode.Buffered;
        binding.UseDefaultWebProxy = true;

        binding.ReaderQuotas.MaxDepth = 32;
        binding.ReaderQuotas.MaxStringContentLength = 65536;
        binding.ReaderQuotas.MaxArrayLength = 131072;
        binding.ReaderQuotas.MaxBytesPerRead = 32768;
        binding.ReaderQuotas.MaxNameTableCharCount = 131072;

        binding.Security.Mode = BasicHttpSecurityMode.Transport;
        binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
        binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;
        binding.Security.Transport.Realm = "";
        binding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;
        binding.Security.Message.AlgorithmSuite = System.ServiceModel.Security.SecurityAlgorithmSuite.Default;

        CustomBinding customBinding = new CustomBinding(binding);
        SecurityBindingElement element = customBinding.Elements.Find<SecurityBindingElement>();
        // Remove security timestamp because it is not used by your original binding
        //element.IncludeTimestamp = false; (element is NULL in my case)

EndpointAddress endpoint = new EndpointAddress("https://myserviceaddress");

        PostingWebServiceClient client = new PostingWebServiceClient(customBinding, endpoint);

        client.ClientCredentials.UserName.UserName = "myusername";
        client.ClientCredentials.UserName.Password = "mypassword";

        client.getActiveChannels(new getActiveChannels());

---

直接使用自定义 Bindgin:

SecurityBindingElement securityElement = SecurityBindingElement.CreateUserNameOverTransportBindingElement();
        securityElement.IncludeTimestamp = false;
        TextMessageEncodingBindingElement encodingElement = new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8);
        HttpsTransportBindingElement transportElement = new HttpsTransportBindingElement();

        CustomBinding customBinding = new CustomBinding(securityElement, encodingElement, transportElement);


EndpointAddress endpoint = new EndpointAddress("https://myserviceaddress");

        PostingWebServiceClient client = new PostingWebServiceClient(customBinding, endpoint);

        client.ClientCredentials.UserName.UserName = "myusername";
        client.ClientCredentials.UserName.Password = "mypassword";

        client.getActiveChannels(new getActiveChannels());

Answer 1

在这种情况下，您不必直接配置 header ，因为您的场景应该直接由 BasicHttpBinding 或 CustomBinding 支持。

如果您需要从 C# 配置它，您必须在代码中创建绑定(bind):

// Helper binding to have transport security with user name token
BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.TransportWithMessageCredential);
binding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;
// Rest of your binding configuration comes here

// Custom binding to have access to more configuration details of basic binding
CustomBinding customBinding = new CustomBinding(binding);
SecurityBindingElement element = customBinding.Elements.Find<SecurityBindingElement>();
// Remove security timestamp because it is not used by your original binding
element.IncludeTimestamp = false;

EndpointAddress address = new EndpointAddress("https://...");

ProxyWebServiceClient client = new ProxyWebServiceClient(customBinding, address);
client.ClientCredentials.UserName.UserName = "...";
client.ClientCredentials.UserName.Password = "...";

其他解决方案是直接构建自定义绑定(bind)，而不是从基本绑定(bind)开始:

SecurityBindingElemetn securityElement = SecurityBindingElement.CreateUserNameOverTransportBindingElement();
securityElement.IncludeTimestamp = false; 
TextMessageEncodingBindingElement encodingElement = new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8);
HttpsTransportBindingElement tranportElement = new HttpsTransportBindingElement();

// Other configurations of basic binding are divided into properties of 
// encoding and transport elements

CustomBinding customBinding = new CustomBinding(securityElement, encodingElement, transportElement);

EndpointAddress address = new EndpointAddress("https://...");

ProxyWebServiceClient client = new ProxyWebServiceClient(customBinding, address);
client.ClientCredentials.UserName.UserName = "...";
client.ClientCredentials.UserName.Password = "...";
