WCF 跨域 Http绑定

跨域服务：

特性WebGet在System.ServiceModel.Web中

    [ServiceContract]    public interface IDomainService    {        [OperationContract]        [WebGet(UriTemplate = "ClientAccessPolicy.xml")]        Message ProvidePolicyFile();    }    public class DomainService:IDomainService    {        #region IDomainService 成员        public System.ServiceModel.Channels.Message ProvidePolicyFile()        {            /*                这样第二次访问会产生文件独占的异常，应该应改为使用 MemoryStream 缓存读取，或者直接使用                XmlReader reader = XmlReader.Create(@"ClientAccessPolicy.xml");             */             //FileStream filestream = File.Open(@"ClientAccessPolicy.xml", FileMode.Open,FileAccess.Read);            //XmlReader reader = XmlReader.Create(filestream);               //ClientAccessPolicy.xml文件要放在exe文件同级             XmlReader reader = XmlReader.Create(@"ClientAccessPolicy.xml");            System.ServiceModel.Channels.Message result = Message.CreateMessage(MessageVersion.None, "", reader);           return result;        }        //CrossDomainServiceBehavior        #endregion    }

 

普通WCF服务：

    [ServiceContract]    public interface IWCFService    {        [OperationContract]        int DoWork(int a, int b);        [OperationContract]        int DoWork2(int a, int b);    }    public class WCFService : IWCFService    {        public int DoWork(int a,int b)        {            return a + b;        }        public int DoWork2(int a, int b)        {            return a - b;        }    }

 

跨域策略文件clientaccesspolicy.xml:

<?xml version="1.0" encoding="utf-8"?><access-policy>  <cross-domain-access>    <policy>      <allow-from http-request-headers="*">        <domain uri="*"/>      </allow-from>      <grant-to>        <resource path="/" include-subpaths="true"/>      </grant-to>    </policy>  </cross-domain-access></access-policy>

 

配置文件App.config:

<?xml version="1.0" encoding="utf-8" ?><configuration>    <system.serviceModel>      <services>        <service behaviorConfiguration="WCFBase.WCFServiceBehavior" name="WCFBase.WCFService">          <endpoint address="" binding="basicHttpBinding" contract="WCFBase.IWCFService">            <identity>              <dns value="localhost" />            </identity>          </endpoint>          <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />          <host>            <baseAddresses>              <add baseAddress="http://localhost:9090/WCFService/" />            </baseAddresses>          </host>        </service>        <service name="WCFBase.DomainService">          <endpoint address="" behaviorConfiguration="DomainServiceBehavior"              binding="webHttpBinding" contract="WCFBase.IDomainService" />          <host>            <baseAddresses>              <add baseAddress="http://localhost:9090/" />            </baseAddresses>          </host>        </service>      </services>            <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>        <behaviors>            <serviceBehaviors>                <behavior name="WCFBase.WCFServiceBehavior">                    <serviceMetadata httpGetEnabled="true" />                    <serviceDebug includeExceptionDetailInFaults="false" />                </behavior>            </serviceBehaviors>          <endpointBehaviors>            <behavior name="DomainServiceBehavior">              <webHttp/>            </behavior>          </endpointBehaviors>        </behaviors>            <!--      <bindings>        <basicHttpBinding>          <binding name="NoneSecurity"   maxBufferPoolSize="12000000" maxReceivedMessageSize="12000000" useDefaultWebProxy="false">            <readerQuotas maxStringContentLength="12000000" maxArrayLength="12000000"/>            <security mode="None"/>          </binding>        </basicHttpBinding>      </bindings>      -->          </system.serviceModel> </configuration>

 

启动方法

    class Program    {        static void Main(string[] args)        {            ServiceHost host = new ServiceHost(typeof(WCFService));            host.Open();            ServiceHost crossDomainserviceHost = new ServiceHost(typeof(DomainService));            crossDomainserviceHost.Open();            Console.WriteLine("Service Start...");            Console.ReadKey();            host.Close();        }    }
