IIS服务寄宿

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

     在学习IIS服务寄宿时参考了文章：如何在IIS中承载WCF服务http://msdn.microsoft.com/zh-cn/library/ms733766.aspx，并按照上面的教程进行配置，

PS:2011-5-28

不按上面的教程进行配置也是可以的，下面我讲一下我的配置过程。

步骤1：首先创建一个解决方案叫做IISHostWCF。

步骤2：在这个解决方案中创建一个”控制台应用程序“Client来测试我们通过IIS寄宿的服务，然后在创建一个CalcService的“WCF服务库“

步骤3：在创建好WCF服务库以后他会自动帮助我们创建契约IService1.cs（接口）以及契约实现Service1.cs

我们在WCF服务哭下创建一个文件夹叫做App_Code，然后将IService1.cs和Service1.cs都放到这个App_Code文件夹中去。

步骤4：将自动生成的配置文件App.config改名为Web.config（这一步很重要，不然会报错说找不到ServiceHost指定的路径）

步骤5:其他内容可以参照前面。

最后通过http://localhost/IISHostedCalc/Service.svc访问时报错，错误内容为：“由于扩展配置问题而无法提供您请求的页面。如果该页面是脚本，请添加处理程序。如果应下载文件，请添加 MIME 映射。”

解决方法：

以管理员运行命令：

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

运行结果如下图所示：

再次登录 http://localhost/IISHostedCalc/Service.svc，运行经过如下图所示

表明服务没有发布成功，按照提示进行修改，修改以后的Web.config为:

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

再次登录http://localhost/IISHostedCalc/Service.svc，会出现如下界面

 SvcUtil.exe应用

可以参考ServiceModel 元数据实用工具 (Svcutil.exe)

我们可以在C:/Program Files/Microsoft SDKs/Windows/v6.0A/bin目录下找到SvcUtil.exe，将这个程序拷贝到D盘根目录下，然后打开cmd，切换到d盘根目录下，输入命令：

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

运行完以后，在d盘根目录下就会自动生成CalculatorService.cs和output.config文件。

在CalculatorService.cs中定义了CalculatorClient这个类，我们在客户端应用程序CalculatorServiceClient中就可以直接通过Calculator这个类创建调用服务的客户端对象。

CalculatorService.cs：

//------------------------------------------------------------------------------ // <auto-generated> // 此代码由工具生成。 // 运行时版本:2.0.50727.4952 // // 对此文件的更改可能会导致不正确的行为，并且如果 // 重新生成代码，这些更改将会丢失。 // </auto-generated> //------------------------------------------------------------------------------ [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")] [System.ServiceModel.ServiceContractAttribute(ConfigurationName="ICalculator")] public interface ICalculator { [System.ServiceModel.OperationContractAttribute(Action="http://tempuri.org/ICalculator/Add", ReplyAction="http://tempuri.org/ICalculator/AddResponse")] double Add(double n1, double n2); [System.ServiceModel.OperationContractAttribute(Action="http://tempuri.org/ICalculator/Subtract", ReplyAction="http://tempuri.org/ICalculator/SubtractResponse")] double Subtract(double n1, double n2); [System.ServiceModel.OperationContractAttribute(Action="http://tempuri.org/ICalculator/Multiply", ReplyAction="http://tempuri.org/ICalculator/MultiplyResponse")] double Multiply(double n1, double n2); [System.ServiceModel.OperationContractAttribute(Action="http://tempuri.org/ICalculator/Divide", ReplyAction="http://tempuri.org/ICalculator/DivideResponse")] double Divide(double n1, double n2); } [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")] public interface ICalculatorChannel : ICalculator, System.ServiceModel.IClientChannel { } [System.Diagnostics.DebuggerStepThroughAttribute()] [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")] public partial class CalculatorClient : System.ServiceModel.ClientBase<ICalculator>, ICalculator { public CalculatorClient() { } public CalculatorClient(string endpointConfigurationName) : base(endpointConfigurationName) { } public CalculatorClient(string endpointConfigurationName, string remoteAddress) : base(endpointConfigurationName, remoteAddress) { } public CalculatorClient(string endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) : base(endpointConfigurationName, remoteAddress) { } public CalculatorClient(System.ServiceModel.Channels.Binding binding, System.ServiceModel.EndpointAddress remoteAddress) : base(binding, remoteAddress) { } public double Add(double n1, double n2) { return base.Channel.Add(n1, n2); } public double Subtract(double n1, double n2) { return base.Channel.Subtract(n1, n2); } public double Multiply(double n1, double n2) { return base.Channel.Multiply(n1, n2); } public double Divide(double n1, double n2) { return base.Channel.Divide(n1, n2); } }  

out.config

<?xml version="1.0" encoding="utf-8"?> <configuration> <system.serviceModel> <bindings> <wsHttpBinding> <binding name="WSHttpBinding_ICalculator" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Message"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm=""> <extendedProtectionPolicy policyEnforcement="Never" /> </transport> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="http://xuwei/IISHostedCalc/service.svc" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_ICalculator" contract="ICalculator" name="WSHttpBinding_ICalculator"> <identity> <servicePrincipalName value="host/xuwei" /> </identity> </endpoint> </client> </system.serviceModel> </configuration> 

创建测试客户端

将CalculatorService.cs和out.config拷贝到CalculatorServiceClient项目下。然后添加现有项CalculatorService，添加完以后再添加应用程序配置文件App.config，将out.config中的内容拷贝到App.config中去，Program.cs代码如下：

using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace CalculatorServiceClient { class Program { static void Main(string[] args) { CalculatorClient client = new CalculatorClient(); // 使用 "client" 变量在服务上调用操作。 Console.WriteLine("x+y={2} when x={0} and y={1}", 1, 2, client.Add(1, 2)); Console.WriteLine("x-y={2} when x={0} and y={1}", 1, 2, client.Subtract(1, 2)); Console.WriteLine("x*y={2} when x={0} and y={1}", 1, 2, client.Multiply(1, 2)); Console.WriteLine("x/y={2} when x={0} and y={1}", 1, 2, client.Divide(1, 2)); Console.Read(); // 始终关闭客户端。 client.Close(); } } }

运行这个CalculatorServiceClient控制台应用程序，运行结果如下：
