服務
下列程式碼和組態要獨立執行。 執行下列其中一項：
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。
程式碼
下列程式碼顯示如何建立無安全性的端點。 根據預設值，BasicHttpBinding 的安全性模式設定為 None。
Dim httpUri As New Uri("https://localhost/Calculator")
' Create the ServiceHost.
Dim myServiceHost As New ServiceHost(GetType(Calculator), httpUri)
' Create a binding that uses HTTP. By default,
' this binding has no security.
Dim b As New BasicHttpBinding()
' Add an endpoint to the service.
myServiceHost.AddServiceEndpoint(GetType(ICalculator), b, "")
' Open the service and wait for calls.
AddMexEndpoint(myServiceHost)
myServiceHost.Open()
Console.Write("Listening....")
Console.ReadLine()
' Close the service when a key is pressed.
myServiceHost.Close()
Uri httpUri = new Uri("https://localhost/Calculator");
// Create the ServiceHost.
ServiceHost myServiceHost = new ServiceHost(typeof(Calculator), httpUri);
// Create a binding that uses HTTP. By default,
// this binding has no security.
BasicHttpBinding b = new BasicHttpBinding();
// Add an endpoint to the service.
myServiceHost.AddServiceEndpoint(typeof(ICalculator), b, "");
// Open the service and wait for calls.
AddMexEndpoint(ref myServiceHost);
myServiceHost.Open();
Console.Write("Listening....");
Console.ReadLine();
// Close the service when a key is pressed.
myServiceHost.Close();
服務組態
下列程式碼會使用組態設定相同端點。
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
<behaviors />
<services>
<service behaviorConfiguration="" name="ServiceModel.Calculator">
<endpoint address="https://localhost/Calculator"
binding="basicHttpBinding"
bindingConfiguration="Basic_Unsecured"
name="BasicHttp_ICalculator"
contract="ServiceModel.ICalculator" />
</service>
</services>
<bindings>
<basicHttpBinding>
<binding name="Basic_Unsecured" />
</basicHttpBinding>
</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：
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：
Dim cc As New CalculatorClient("EndpointConfigurationName")CalculatorClient cc = new CalculatorClient("EndpointConfigurationName");
程式碼
下列程式碼顯示使用不安全端點的基本 WCF 用戶端。
' Create an instance of the BasicHttpBinding.
' By default, there is no security.
Dim myBinding As New BasicHttpBinding()
' Create the address string, or get it from configuration.
Dim httpUri As String = "https://localhost/Calculator"
' Create an endpoint address with the address.
Dim myEndpoint As New EndpointAddress(httpUri)
' Create an instance of the WCF client. The client
' code was generated using the Svcutil.exe tool.
Dim cc As New CalculatorClient(myBinding, myEndpoint)
Try
cc.Open()
' Begin using the calculator.
Console.WriteLine(cc.Divide(100, 2))
' 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
// Create an instance of the BasicHttpBinding.
// By default, there is no security.
BasicHttpBinding myBinding = new BasicHttpBinding();
// Create the address string, or get it from configuration.
string httpUri = "https://localhost/Calculator";
// Create an endpoint address with the address.
EndpointAddress myEndpoint = new EndpointAddress(httpUri);
// Create an instance of the WCF client. The client
// code was generated using the Svcutil.exe tool.
CalculatorClient cc = new CalculatorClient(myBinding, myEndpoint);
try
{
cc.Open();
// Begin using the calculator.
Console.WriteLine(cc.Divide(100, 2));
// Close the client.
cc.Close();
}
catch (TimeoutException tex)
{
Console.WriteLine(tex.Message);
cc.Abort();
}
catch (CommunicationException cex)
{
Console.WriteLine(cex.Message);
cc.Abort();
}
finally
{
Console.WriteLine("Closed the client");
Console.ReadLine();
}
