多個端點

多個端點範例會示範如何在服務上設定多個端點,以及如何從用戶端與每個端點進行通訊。此範例是以使用者入門範例為基礎。服務組態已修改成定義支援 ICalculator 合約的兩個端點,但是每個端點會位在不同的位址,同時使用不同的繫結。用戶端組態與程式碼已修改成可與這兩個服務端點進行通訊。

ms751515.note(zh-tw,VS.90).gif注意:
此範例的安裝程序與建置指示位於本主題的結尾。

服務 Web.config 檔已修改成定義兩個端點,每個端點都支援相同的 ICalculator 合約,但是分別位在不同的位址及使用不同繫結。第一個端點是定義位在基底位址且 basicHttpBinding 使用繫結,其並未啟用安全性。第二個端點是定義位在 {baseaddress}/secure 且使用 wsHttpBinding 繫結,其已透過搭配 Windows 驗證使用 WS-Security,因此預設為安全端點。

<service 
    name="Microsoft.ServiceModel.Samples.CalculatorService"
    behaviorConfiguration="CalculatorServiceBehavior">
  <!-- This endpoint is exposed at the base address provided by host:       https://localhost/servicemodelsamples/service.svc  -->
  <endpoint address=""
            binding="basicHttpBinding"
            contract="Microsoft.ServiceModel.Samples.ICalculator" />
  <!-- secure endpoint exposed at {base address}/secure:       https://localhost/servicemodelsamples/service.svc/secure -->
  <endpoint address="secure"
            binding="wsHttpBinding"
            contract="Microsoft.ServiceModel.Samples.ICalculator" />
  ...
</service>

這兩個端點也都會設定在用戶端。這些端點有指定名稱,因此呼叫者可以將需要的端點名稱傳遞至用戶端的建構函式中。

<client>
  <!-- Passing "basic" into the constructor of the CalculatorClient       class selects this endpoint.-->
  <endpoint name="basic"
            address="https://localhost/servicemodelsamples/service.svc" 
            binding="basicHttpBinding" 
            contract="Microsoft.ServiceModel.Samples.ICalculator" />
  <!-- Passing "secure" into the constructor of the CalculatorClient       class selects this endpoint.-->
  <endpoint name="secure"
address="https://localhost/servicemodelsamples/service.svc/secure" 
            binding="wsHttpBinding" 
            contract="Microsoft.ServiceModel.Samples.ICalculator" />
</client>

用戶端會同時使用這些端點,如下列程式碼所示。

static void Main()
{
    // Create a client to the basic endpoint configuration.
    CalculatorClient client = new CalculatorClient("basic");
    Console.WriteLine("Communicate with basic endpoint.");
    // call operations
    DoCalculations(client);

    // Close the client and release resources.
    client.Close();

    // Create a client to the secure endpoint configuration.
    client = new CalculatorClient("secure");
    Console.WriteLine("Communicate with secure endpoint.");
    // Call operations.
    DoCalculations(client);

    // Close the client and release resources.
    client.Close();

    Console.WriteLine();
    Console.WriteLine("Press <ENTER> to terminate client.");
    Console.ReadLine();
}

當您執行用戶端時,與這兩個端點的互動都會顯示。

Communicate with basic endpoint.
Add(100,15.99) = 115.99
Subtract(145,76.54) = 68.46
Multiply(9,81.25) = 731.25
Divide(22,7) = 3.14285714285714
Communicate with secure endpoint.
Add(100,15.99) = 115.99
Subtract(145,76.54) = 68.46
Multiply(9,81.25) = 731.25
Divide(22,7) = 3.14285714285714

Press <ENTER> to terminate client.

若要設定、建置及執行範例

  1. 請確定您已執行 Windows Communication Foundation 範例的單次安裝程序

  2. 若要建置方案的 C# 或 Visual Basic .NET 版本,請遵循建置 Windows Communication Foundation 範例中的指示。

  3. 若要在單一或跨電腦的組態中執行本範例,請遵循執行 Windows Communication Foundation 範例中的指示。
