IIS服務寄宿

本文參考：http://log.medcl.net/item/2010/03/wcf-extensions-under-iis7-configuration-issues/

 

     在學習IIS服務寄宿時參考了文章：如何在IIS中承載WCF服務http://msdn.microsoft.com/zh-cn/library/ms733766.aspx，並按照上面的教程進行配置，

 

PS:2011-5-28

不按上面的教程進行配置也是可以的，下面我講一下我的配置過程。

步驟1：首先建立一個解決方案叫做IISHostWCF。

步驟2：在這個解決方案中建立一個”控制台應用程式“Client來測試我們通過IIS寄宿的服務，然後在建立一個CalcService的“WCF服務庫“

步驟3：在建立好WCF服務庫以後他會自動協助我們建立契約IService1.cs（介面）以及契約實現Service1.cs

我們在WCF服務哭下建立一個檔案夾叫做App_Code，然後將IService1.cs和Service1.cs都放到這個App_Code檔案夾中去。

步驟4：將自動產生的設定檔App.config改名為Web.config（這一步很重要，不然會報錯說找不到ServiceHost指定的路徑）

步驟5:其他內容可以參照前面。

 

 

最後通過http://localhost/IISHostedCalc/Service.svc訪問時報錯，錯誤內容為：“由於擴充配置問題而無法提供您請求的頁面。如果該頁面是指令碼，請添加處理常式。如果應下載檔案，請添加 MIME 對應。”

解決方案：

以管理員運行命令：

C:/Windows/Microsoft.NET/Framework/v3.0/Windows Communication Foundation/ServiceModelReg.exe -i

運行結果如所示：

再次登入 http://localhost/IISHostedCalc/Service.svc，運行經過如所示

表明服務沒有發布成功，按照提示進行修改，修改以後的Web.config為:

<?xml version="1.0" encoding="utf-8" ?><br /><configuration><br /> <system.serviceModel><br /> <behaviors><br /> <serviceBehaviors><br /> <behavior name="MyServiceTypeBehaviors" ><br /> <serviceMetadata httpGetEnabled="true" /><br /> </behavior><br /> </serviceBehaviors><br /> </behaviors><br /> <services><br /> <service name="Microsoft.ServiceModel.Samples.CalculatorService" behaviorConfiguration="MyServiceTypeBehaviors" ><br /> <!-- This endpoint is exposed at the base address provided by host: http://localhost/servicemodelsamples/service.svc --><br /> <endpoint address="" binding="wsHttpBinding" contract="Microsoft.ServiceModel.Samples.ICalculator" /><br /> </service><br /> </services><br /> </system.serviceModel><br /></configuration>

再次登入http://localhost/IISHostedCalc/Service.svc，會出現如下介面

 SvcUtil.exe應用

可以參考ServiceModel 中繼資料工具 + 生產力 (Svcutil.exe)

我們可以在C:/Program Files/Microsoft SDKs/Windows/v6.0A/bin目錄下找到SvcUtil.exe，將這個程式拷貝到D盤根目錄下，然後開啟cmd，切換到d盤根目錄下，輸入命令：

svcutil.exe http://xuwei/IISHostedCalc/service.svc?wsdl

運行完以後，在d盤根目錄下就會自動產生CalculatorService.cs和output.config檔案。

 

在CalculatorService.cs中定義了CalculatorClient這個類，我們在用戶端應用程式CalculatorServiceClient中就可以直接通過Calculator這個類建立調用服務的用戶端對象。

CalculatorService.cs：

out.config

建立測試用戶端

將CalculatorService.cs和out.config拷貝到CalculatorServiceClient項目下。然後添加現有項CalculatorService，添加完以後再添加應用程式設定檔App.config，將out.config中的內容拷貝到App.config中去，Program.cs代碼如下：

using System;<br />using System.Collections.Generic;<br />using System.Linq;<br />using System.Text;<br />namespace CalculatorServiceClient<br />{<br /> class Program<br /> {<br /> static void Main(string[] args)<br /> {<br /> CalculatorClient client = new CalculatorClient();<br /> // 使用 "client" 變數在服務上叫用作業。<br /> Console.WriteLine("x+y={2} when x={0} and y={1}", 1, 2, client.Add(1, 2));<br /> Console.WriteLine("x-y={2} when x={0} and y={1}", 1, 2, client.Subtract(1, 2));<br /> Console.WriteLine("x*y={2} when x={0} and y={1}", 1, 2, client.Multiply(1, 2));<br /> Console.WriteLine("x/y={2} when x={0} and y={1}", 1, 2, client.Divide(1, 2));<br /> Console.Read();<br /> // 始終關閉用戶端。<br /> client.Close();<br /> }<br /> }<br />}<br />

運行這個CalculatorServiceClient控制台應用程式，運行結果如下：
