WCF双工通讯+身份认证

证书

  以管理员身份打开VS开发人员命令提示符工具

然后输入如下字符串

  makecert -sr localmachine -ssRoot -n CN=GreenWhale -sky exchange -pe -r。

回车返回Success即可。

然后打开“C:\Windows\System32\en-US\certlm.msc”  Zh-CN也可 “C:\Windows\System32\zh-CN\certlm.msc”

别打错了不是这个“certmgr.msc”

然后就可以看到证书了，导出证书，软件发布后让客户端安装此证书即可。

服务端

 服务端回调接口：

using System.ServiceModel;

using System.Net;

namespace WcfService1

{

    publicinterface IServerCallClient

    {

        [OperationContract]

        IPEndPointServerRequestClientIP();

        [OperationContract]

        voidServerSayMsg(string text);

    }

}

服务接口

using System;

using System.ServiceModel;

namespace WcfService1

{

    [ServiceContract(CallbackContract=typeof(IServerCallClient))]

    publicinterface IClientCallServer

    {

        [OperationContract]

        voidClientSayToServer(string text);

        [OperationContract]

        DateTimeClientRequestDateTime();

    }

}

WCF 服务端代码实现

请注意，服务端回调客户端时 客户端的链接必须没有断开，断开了就无法回调了，

using System;

using System.Collections.Generic;

using System.Diagnostics;

using System.IO;

using System.Linq;

using System.Net;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

using System.Timers;

namespace WcfService1

{

    // 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码、svc 和配置文件中的类名“Service1”。

    // 注意: 为了启动 WCF 测试客户端以测试此服务，请在解决方案资源管理器中选择 Service1.svc 或 Service1.svc.cs，然后开始调试。

    [ServiceBehavior(InstanceContextMode=InstanceContextMode.Single)]

    publicclass ClientCallServer :IClientCallServer,IDisposable

    {

        Timer timer= newTimer();

        publicClientCallServer()

        {

            timer.Elapsed+= Timer_Elapsed;

            timer.Interval= 5000;

            timer.Start();

        }

        privatevoid Timer_Elapsed(object sender,ElapsedEventArgs e)

        {

            if (ServerCallClient!= null)

            {

                foreach (var itemin ServerCallClient)

                {

                    item.ServerSayMsg("SB");

                }

            }

        }

        publicstatic List<IServerCallClient> ServerCallClient= newList<IServerCallClient>();

        publicDateTime ClientRequestDateTime()

        {

            returnDateTime.Now;

        }

        publicvoid ClientSayToServer(string text)

        {

            var channel= OperationContext.Current.GetCallbackChannel<IServerCallClient>();

            ServerCallClient.Add(channel);

            Debug.WriteLine(OperationContext.Current.SessionId);

            Debug.WriteLine(text);

        }

        publicvoid Dispose()

        {

            ServerCallClient.Clear();

        }

    }

}

身份认证

实现身份认证需要服务端继承System.IdentityModel.Selectors.UserNamePasswordValidator类。同理需要引用System.IdentityModel.Dll；

namespace WcfService1

{

    /// <summary>

    /// WCF身份认证

    /// </summary>

    publicclass WCFValidator : System.IdentityModel.Selectors.UserNamePasswordValidator

    {

        /// <summary>

        /// 身份及密码验证

        /// </summary>

        /// <param name="userName"></param>

        /// <param name="password"></param>

        publicoverride void Validate(string userName,string password)

        {

            if (userName== "1234"&& password== "1234")//身份验证不过则报错，过了就过了。

            {

            }

            else

            {

                thrownew System.IdentityModel.Tokens.SecurityTokenException("Unknown Username or Password");

            }

        }

    }

}

客户端

客户端很简单，首先引用WCF服务,然后在连接时输入对应的账号和密码即可。

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Net;

using System.ServiceModel;

using System.Text;

using System.Windows.Forms;

using System.Xml;

using WindowsFormsApp1.Service;

namespace WindowsFormsApp1

{

    publicpartial class Form1 :Form, IClientCallServerCallback

    {

        publicForm1()

        {

            InitializeComponent();

            context= newInstanceContext(this);

            client= newClientCallServerClient(context);

        }

        publicIPEndPoint ServerRequestClientIP()

        {

            thrownew NotImplementedException();

        }

        InstanceContext context;

        publicvoid ServerSayMsg(string text)

        {

            MessageBox.Show(text);

        }

        ClientCallServerClient client;

        privatevoid button1_Click(object sender,EventArgs e)

        {

          //  certificateValidationMode

            client.ClientCredentials.UserName.UserName= "1234";

            client.ClientCredentials.UserName.Password= "1234";

            client.ClientSayToServer("Fuck");

        }

    }

}
