WCF NetTcpBinding Transport安全模式(2) 默认安全配置
新建一个类库名为“WcfSecurityExampleServiceLibrary”的类库项目，添加如代码清单11-10所示的契约，其中将示例契约命名为HelloService。
代码清单11-10 HelloService契约
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
namespace WcfSecurityExampleServiceLibrary
{
[ServiceContract]
public interface IHelloService
{
[OperationContract]
string GetHello();
}
}
代码清单11-11是HelloService契约的实现。
代码清单11-11 HelloService契约的实现
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
namespace WcfSecurityExampleServiceLibrary
{
public class HelloService : IHelloService
{
public string GetHello()
{
if (ServiceSecurityContext.Current != null)
{
if (!ServiceSecurityContext.Current.IsAnonymous)
{
return "Hello:" + ServiceSecurityContext.Current.PrimaryIdentity.Name + ";type="
+ ServiceSecurityContext.Current.PrimaryIdentity.AuthenticationType;
}
return "";
}
else
{
return "hello";
} }
}
}
这里采用控制台程序做自托管宿主，宿主代码如代码清单11-12所示。
代码清单11-12 宿主代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using WcfSecurityExampleServiceLibrary;
namespace SimpleHost
{
class Program
{
static void Main(string[] args)
{
ServiceHost hostForHello = new ServiceHost(typeof(HelloService));
hostForHello.Open();
try
{
while (true)
{
}
}
catch
{
hostForHello.Abort();
}
}
}
}
宿主配置文件如代码清单11-13所示。
代码清单11-13 宿主配置文件
<?xml version="1.0"?>
<configuration>
<system.serviceModel>
<services>
<service name="WcfSecurityExampleServiceLibrary.HelloService" behaviorConfiguration="mex">
<host>
<baseAddresses>
<add baseAddress="net.tcp://127.0.0.1:64567/"/>
</baseAddresses>
</host>
<endpoint address="net.tcp://127.0.0.1:64567/HelloService" binding="netTcpBinding"
bindingConfiguration="tcpWindowsSecurity" name="helloEndPoint"
contract="WcfSecurityExampleServiceLibrary.IHelloService"/>
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
</service>
</services>
<bindings>
<netTcpBinding>
<binding name="tcpWindowsSecurity">
</binding>
</netTcpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="mex">
<serviceMetadata />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
</configuration>
代码清单11-13所示的配置文件并没有对netTcpBinding做任何的安全配置，因此一切将采用默认设置。
客户端实现如代码清单11-14所示。
代码清单11-14 客户端实现
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using WcfSecurityExampleServiceLibrary;
namespace WcfSecurityExampleConsoleClient
{
class Program
{
static void Main(string[] args)
{
using (ChannelFactory<IHelloService> channelFactory = new ChannelFactory<IHelloService>("helloEndPoint"))
{
IHelloService helloService = channelFactory.CreateChannel();
using (helloService as IDisposable)
{
Console.WriteLine(helloService.GetHello());
}
}
Console.Read();
}
}
}
在代码请单11-14所示的实现中，首先根据配置文件创建服务管道，然后请求服务的GetHello方法，输出结果。客户端的配置文件，如代码清单11-15所示。
代码清单11-15 客户端配置文件
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="tcpWindowsSecurity">
</binding>
