WCF rest 的帮助页面和缓存机制

打开vs2010 在工具选项中选择扩展管理器——联机库安装WCF REST Service Template 40(CS)模板

安装后新建wcf服务应用程序，删除默认建立的文件。

新建RestWcf4HelpPage.svc，代码如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Activation;
using System.ServiceModel.Web;
using System.Text;namespace RestWcf
{[ServiceBehavior(IncludeExceptionDetailInFaults=false)][AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]public class RestWcf4HelpPage : IRestWcf4HelpPage{#region IRestWcf4HelpPage 成员[WebGet(UriTemplate="/Rest/Get/{id}")]public string GetData(string id){return "Hello Rest GetData";}[WebInvoke(UriTemplate="/Rest/Add/{id}",Method="POST")]public string AddData(string id){return "Hello Rest AddData";}[WebInvoke(UriTemplate = "/Rest/Update/{id}", Method = "PUT")]public string UpdateData(string id){return "Hello Rest UpdateData";}[WebInvoke(UriTemplate = "/Rest/Delete/{id}", Method = "Delete")]public string DeleteData(string id){return "Hello Rest DeleteData";}#endregion}[XmlSerializerFormat][ServiceContract]interface IRestWcf4HelpPage{[OperationContract]string GetData(string id);[OperationContract]string AddData(string id);[OperationContract]string UpdateData(string id);[OperationContract]string DeleteData(string id);}
}

然后在建立RestWcf4Cache.svc，代码如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Activation;
using System.ServiceModel.Web;
using System.Text;namespace RestWcf
{[ServiceBehavior(IncludeExceptionDetailInFaults=false)][AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]public class RestWcf4Cache:IRestWcf4Cache{#region IRestWcf4Cache 成员[AspNetCacheProfile("CacheFor10Senconds")][WebGet(UriTemplate = "/Rest/Get/{id}")]public string GetData(string id){return "Hello Rest GetData " + DateTime.Now.ToString();}#endregion}[ServiceContract]interface IRestWcf4Cache{[OperationContract]string GetData(string id);}
}

然后在配置web.config文件，其中duration值缓存的有效时间。

<?xml version="1.0" encoding="utf-8"?>
<configuration><system.web><compilation debug="true" targetFramework="4.0" /><caching><outputCacheSettings><outputCacheProfiles ><add name="CacheFor10Senconds" duration="10" varyByParam="format"/><add name="CacheFor30Senconds" duration="30" varyByParam="format"/></outputCacheProfiles></outputCacheSettings></caching></system.web><system.serviceModel><services><service name="RestWcf.RestWcf4HelpPage"><endpoint address="" behaviorConfiguration="RestWcf4HelpPageBehavior"binding="webHttpBinding" contract="RestWcf.IRestWcf4HelpPage" /></service><service name="RestWcf.RestWcf4Cache"><endpoint address="" behaviorConfiguration="RestWcf4CacheBehavior"binding="webHttpBinding" contract="RestWcf.IRestWcf4Cache" /></service></services><behaviors><endpointBehaviors><behavior name="RestWcf4HelpPageBehavior"><webHttp helpEnabled="true" /></behavior><behavior name="RestWcf4CacheBehavior"><webHttp helpEnabled="true" /></behavior></endpointBehaviors><serviceBehaviors><behavior name=""><serviceMetadata httpGetEnabled="true" /><serviceDebug includeExceptionDetailInFaults="false" /></behavior></serviceBehaviors></behaviors><serviceHostingEnvironment aspNetCompatibilityEnabled="true"multipleSiteBindingsEnabled="true" /></system.serviceModel><system.webServer><modules runAllManagedModulesForAllRequests="true"/></system.webServer></configuration>
