沒有安全保障的內部網路用戶端與服務

  • 發行項

下圖說明為了在安全私人網路上提供資訊給 Windows Communication Foundation (WCF) 應用程式而開發的簡單 WCF 服務。 由於資料的重要性較低、預期網路本質上是安全的，或者安全性是由 WCF 基礎結構的下一層所提供，因此不需要安全性。

特性 描述
安全性模式 無
傳輸 TCP
繫結 NetTcpBinding
互通性 僅限 WCF

完整性 無
保密 無

服務

下列程式碼和組態要獨立執行。 執行下列其中一項動作：

  • 使用不含組態的程式碼建立獨立服務。

  • 使用提供的組態建立服務，但不要定義任何端點。

代碼

下列程式碼會示範如何建立無安全性的端點：

Uri tcpUri = new Uri("net.tcp://localhost:8008/Calculator");

// Create the ServiceHost.
ServiceHost sh = new ServiceHost(typeof(Calculator), tcpUri);

// Create a binding that uses TCP and set the security mode to none.
NetTcpBinding b = new NetTcpBinding();
b.Security.Mode = SecurityMode.None;

// Add an endpoint to the service.
sh.AddServiceEndpoint(typeof(ICalculator), b, "");
// Open the service and wait for calls.
sh.Open();

string listenUri = sh.Description.Endpoints[0].ListenUri.AbsoluteUri;
Console.WriteLine("Listening on: {0}", listenUri);
Console.Write("Press Enter to end the service");
Console.ReadLine();
// Close the service when a key is pressed.


Dim tcpUri As New Uri("net.tcp://localhost:8008/Calculator")

' Create the ServiceHost.
Dim sh As New ServiceHost(GetType(Calculator), tcpUri)

' Create a binding that uses TCP and set the security mode to none.
Dim b As New NetTcpBinding()
b.Security.Mode = SecurityMode.None

' Add an endpoint to the service.
sh.AddServiceEndpoint(GetType(ICalculator), b, "")
' Open the service and wait for calls.
sh.Open()

Dim listenUri As String = sh.Description.Endpoints(0).ListenUri.AbsoluteUri
Console.WriteLine("Listening on: {0}", listenUri)
Console.Write("Press Enter to end the service")
Console.ReadLine()
' Close the service when a key is pressed.

組態

下列程式碼會設定使用組態的相同端點：

<?xml version="1.0" encoding="utf-8"?>  
<configuration>  
  <system.serviceModel>  
    <behaviors />  
    <services>  
      <service behaviorConfiguration=""
               name="ServiceModel.Calculator">  
        <endpoint address="net.tcp://localhost:8008/Calculator"
                  binding="netTcpBinding"  
                  bindingConfiguration="tcp_Unsecured"
                  name="netTcp_ICalculator"  
                  contract="ServiceModel.ICalculator" />  
      </service>  
    </services>  
    <bindings>  
      <netTcpBinding>  
        <binding name="tcp_Unsecured">  
          <security mode="None" />  
        </binding>  
      </netTcpBinding>  
    </bindings>  
    <client />  
  </system.serviceModel>  
</configuration>

用戶端

下列程式碼和組態要獨立執行。 執行下列其中一項動作：

  • 使用此程式碼 (和用戶端程式碼) 建立獨立用戶端。

  • 建立未定義任何端點位址的用戶端， 然後改用可接受組態名稱當做引數的用戶端建構函式。 例如：

    CalculatorClient cc = new CalculatorClient("EndpointConfigurationName");

    Dim cc As New CalculatorClient("EndpointConfigurationName")

代碼

下列程式碼示範使用 TCP 通訊協定來存取不安全端點的基本 WCF 用戶端。

// Create an instance of the NetTcpBinding and set the
// security mode to none.
NetTcpBinding myBinding = new NetTcpBinding();
myBinding.Security.Mode = SecurityMode.None;

// Create the address string, or get it from configuration.
string tcpUri = "net.tcp://machineName:8008/Calculator";

// Create an endpoint address with the address.
EndpointAddress myEndpointAddress = new EndpointAddress(tcpUri);

// Create an instance of the WCF client. The client
// code was generated using the Svcutil.exe tool.
CalculatorClient cc = new CalculatorClient(myBinding, myEndpointAddress);
try
{
    cc.Open();

' Create an instance of the NetTcpBinding and set the
' security mode to none.
Dim myBinding As New NetTcpBinding()
myBinding.Security.Mode = SecurityMode.None

' Create the address string, or get it from configuration.
Dim tcpUri As String = "net.tcp://machineName:8008/Calculator"

' Create an endpoint address with the address.
Dim myEndpointAddress As New EndpointAddress(tcpUri)

' Create an instance of the WCF client. The client
' code was generated using the Svcutil.exe tool.
Dim cc As New CalculatorClient(myBinding, myEndpointAddress)
Try
    cc.Open()

組態

下列組態程式碼會套用至用戶端：

<?xml version="1.0" encoding="utf-8"?>  
<configuration>  
  <system.serviceModel>  
    <bindings>  
      <netTcpBinding>  
        <binding name="NetTcpBinding_ICalculator" >  
          <security mode="None">  
          </security>  
        </binding>  
      </netTcpBinding>  
    </bindings>  
    <client>  
      <endpoint address="net.tcp://machineName:8008/Calculator "  
                binding="netTcpBinding"
                bindingConfiguration="NetTcpBinding_ICalculator"  
                contract="ICalculator"
                name="NetTcpBinding_ICalculator" />  
    </client>  
  </system.serviceModel>  
</configuration>
