匿名客户端的传输安全性

此 Windows Communication Foundation (WCF) 方案使用传输安全性 (HTTPS) 确保保密性和完整性。 必须使用安全套接字层 (SSL) 证书对服务器进行身份验证，并且客户端必须信任服务器的证书。 客户端不通过任何机制进行身份验证，因此是匿名的。

有关示例应用程序，请参见 WS 传输安全性。 有关传输安全性的详细信息，请参阅传输安全性概述。

有关将证书用于服务的更多信息，请参阅使用证书和如何：使用 SSL 证书配置端口。

服务

下面的代码和配置应独立运行。 执行下列操作之一：

• 使用代码（而不使用配置）创建独立服务。

• 使用提供的配置创建服务，但不定义任何终结点。

代码

下面的代码演示如何使用传输安全创建终结点：

// Create the binding.
WSHttpBinding binding = new WSHttpBinding();
binding.Security.Mode = SecurityMode.Transport;
binding.Security.Transport.ClientCredentialType =
      HttpClientCredentialType.None;

// Create the URI for the endpoint.
Uri httpUri = new Uri("https://localhost/Calculator");

// Create the service host and add an endpoint.
ServiceHost myServiceHost =
    new ServiceHost(typeof(ServiceModel.Calculator), httpUri);
myServiceHost.AddServiceEndpoint(
    typeof(ServiceModel.ICalculator), binding, "");

// Open the service host.
myServiceHost.Open();
Console.WriteLine("Press Enter to exit....");
Console.ReadLine();

// Close the service.
myServiceHost.Close();

' Create the binding.
Dim binding As New WSHttpBinding()
binding.Security.Mode = SecurityMode.Transport
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None

' Create the URI for the endpoint.
Dim httpUri As New Uri("https://localhost/Calculator")

' Create the service host and add an endpoint.
Dim myServiceHost As New ServiceHost(GetType(ServiceModel.Calculator), httpUri)
myServiceHost.AddServiceEndpoint(GetType(ServiceModel.ICalculator), binding, "")

' Open the service host.
myServiceHost.Open()
Console.WriteLine("Press Enter to exit....")
Console.ReadLine()

' Close the service.
myServiceHost.Close()

Configuration

下面的代码使用配置设置相同的终结点。 客户端不通过任何机制进行身份验证，因此是匿名的。

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="ServiceModel.Calculator">
        <endpoint address="https://localhost/Calculator"
                  binding="wsHttpBinding"
                  bindingConfiguration="WSHttpBinding_ICalculator"
                  name="SecuredByTransportEndpoint"
                  contract="ServiceModel.ICalculator" />
      </service>
    </services>
    <bindings>
      <wsHttpBinding>
        <binding name="WSHttpBinding_ICalculator">
          <security mode="Transport">
            <transport clientCredentialType="None" />
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>
    <client />
  </system.serviceModel>
</configuration>

客户端

下面的代码和配置应独立运行。 执行下列操作之一：

• 使用代码（和客户端代码）创建独立客户端。

• 创建不定义任何终结点地址的客户端。 而使用将配置名称作为自变量的客户端构造函数。 例如：

  CalculatorClient cc = new CalculatorClient("EndpointConfigurationName");
  

  Dim cc As New CalculatorClient("EndpointConfigurationName")
  

代码

// Create the binding.
WSHttpBinding myBinding = new WSHttpBinding();
myBinding.Security.Mode = SecurityMode.Transport;
myBinding.Security.Transport.ClientCredentialType =
    HttpClientCredentialType.None;

// Create the endpoint address. Note that the machine name
// must match the subject or DNS field of the X.509 certificate
// used to authenticate the service.
EndpointAddress ea = new
    EndpointAddress("https://machineName/Calculator");

// Create the client. The code for the calculator
// client is not shown here. See the sample applications
// for examples of the calculator code.
CalculatorClient cc =
    new CalculatorClient(myBinding, ea);

// Begin using the client.
try
{
    cc.Open();
    Console.WriteLine(cc.Add(100, 1111));

    // Close the client.
    cc.Close();
}

' Create the binding.
Dim myBinding As New WSHttpBinding()
myBinding.Security.Mode = SecurityMode.Transport
myBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None

' Create the endpoint address. Note that the machine name
' must match the subject or DNS field of the X.509 certificate
' used to authenticate the service.
Dim ea As New EndpointAddress("https://machineName/Calculator")

' Create the client. The code for the calculator
' client is not shown here. See the sample applications
' for examples of the calculator code.
Dim cc As New CalculatorClient(myBinding, ea)

' Begin using the client.
Try
    cc.Open()

    Console.WriteLine(cc.Add(100, 11))
    Console.ReadLine()

    ' Close the client.
    cc.Close()
Catch tex As TimeoutException
    Console.WriteLine(tex.Message)
    cc.Abort()
Catch cex As CommunicationException
    Console.WriteLine(cex.Message)
    cc.Abort()
Finally
    Console.WriteLine("Closed the client")
    Console.ReadLine()
End Try

Configuration

下面的配置可代替代码用于设置服务。

<configuration>
  <system.serviceModel>
    <bindings>
      <wsHttpBinding>
        <binding name="WSHttpBinding_ICalculator" >
          <security mode="Transport">
            <transport clientCredentialType="None" />
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>
    <client>
      <endpoint address="https://machineName/Calculator"
                binding="wsHttpBinding"
                bindingConfiguration="WSHttpBinding_ICalculator"
                contract="ICalculator"
                name="WSHttpBinding_ICalculator" />
    </client>
  </system.serviceModel>
</configuration>
