【WCF安全】使用X509证书自定义验证

接触WCF时间比较短，在项目中要使用X509证书，纠结好几天终于有了结论，因此为了方便日后查阅和园友交流特意单独将部分代码提出，并做以记录。

1.准备工作

制作X509证书，此处用到三个证书名称

导入证书步骤：

第一步：运行mmc 打开控制台，添加证书

 

将证书导入，再设置证书的读取权限

 

 

2.方便阅读下文，先展示下代码整体结构

3.编写服务代码(WcfSite工程下)

服务一：

public class HelloService : IHelloService
    {
        public string DoWork()
        {
            return "Hello";
        }
    }

[ServiceContract]
    public interface IHelloService
    {
        [OperationContract]
        string DoWork();
    }

服务二：

public class HiService : IHiService
    {
        public string DoWork()
        {
            return "Hi";
        }
    }


[ServiceContract]
    public interface IHiService
    {
        [OperationContract]
        string DoWork();
    }

服务三：

public class NiHaoService : INiHaoService
    {
        public string DoWork()
        {
            return "你好";
        }
    }


[ServiceContract]
    public interface INiHaoService
    {
        [OperationContract]
        string DoWork();
    }

 

服务写完之后开始着手准备X509的自定义验证

此实例的验证逻辑如下：

第一步：验证客户端x509证书的有效性；

当客户端试图调用服务资源时，首先进入此处进行x509的验证

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IdentityModel.Selectors;
using System.Security.Cryptography.X509Certificates;
using System.Xml;
using System.ServiceModel;

namespace WcfSite.Code
{
    /// <summary>

        private static Dictionary<string, string> SNList = new Dictionary<string, string>();
        private static Object objlock = new object();

        #region X509CertificateValidator重写
        /// <summary>
        /// 验证X509证书
        /// </summary>
        /// <param name="certificate"></param>
        public override void Validate(X509Certificate2 certificate)
        {
            if (certificate == null)
            {
                throw new FaultException("请安装X509证书");
            }
            if (SNList.Count == 0)
            {
                GetX509SerialNumberList();
            }
            lock (objlock)
            {
                if (!SNList.ContainsKey(certificate.Subject) || !SNList.ContainsValue(certificate.SerialNumber.ToUpper()))
                {
                    throw new FaultException("X509证书无效");
                }
            }
        }

        #endregion

        #region 私有方法
        /// <summary>
        /// 获取x509证书序列号
        /// </summary>
        private void GetX509SerialNumberList()
        {
            XmlDocument doc = new XmlDocument();
            doc.Load(AppDomain.CurrentDomain.BaseDirectory + "X509SerialNumbers.xml");
            XmlNodeList nodes = doc.SelectNodes("X509SN/SerialNumbers/Number");
            foreach (XmlNode node in nodes)
            {
                string ca = String.Empty;//CA名称
                string sn = String.Empty;//CA序列号
                foreach (XmlAttribute xa in node.Attributes)//校验用户名密码
                {
                    if (xa.Name == "CA")
                        ca = xa.Value;
                    else if (xa.Name == "SN")
                        sn = xa.Value;
                }
                if (!String.IsNullOrEmpty(ca) && !String.IsNullOrEmpty(sn))
                    SNList.Add(ca, sn.ToUpper());
            }
        }
        #endregion
    }
}

 

第二步：验证客户端是否有权限调用将要调用的服务资源

验证客户端使用的x509证书是否有权限调用服务资源

/// <summary>
    /// 提供对服务操作的授权访问检查
    /// </summary>
    public class CustomServiceAuthorizationManager : System.ServiceModel.ServiceAuthorizationManager
    {

        {
            //请求调用的资源url
            string action = operationContext.RequestContext.RequestMessage.Headers.Action;
            Console.ForegroundColor = ConsoleColor.Red;
            Console.ForegroundColor = ConsoleColor.White;
            //ClaimSet 表示与某个实体关联的声明的集合。
            //获取与授权策略关联的声明集
            foreach (System.IdentityModel.Claims.ClaimSet cs in operationContext.ServiceSecurityContext.AuthorizationContext.ClaimSets)
            {
                if (cs.Issuer == System.IdentityModel.Claims.ClaimSet.System)
                {
                    foreach (System.IdentityModel.Claims.Claim claim in cs.FindClaims("http://tempuri.org/", System.IdentityModel.Claims.Rights.PossessProperty))
                    {
                        //校验是否有调用权限
                        if (claim.Resource.ToString() == action)
                        {
                            return true;//通过
                        }
                        else
                        {
                            string url = action.Substring(0, action.LastIndexOf('/'));
                            if (claim.Resource.ToString() == url + "/all")//可以调用该服务下所有的方法
                                return true;
                        }

                    }
                }
            }
            return false;//不通过
        }

        #endregion
    }

        #endregion

    }

到此，所有服务方法和x509自定义验证代码都已完成。之后将要在配置文件中配置客户端x509的权限信息

首先配置客户端x509证书的序列号，因为此实例是通过序列号验证证书是否有效的(X509SerialNumbers.xml)

<?xml version="1.0" encoding="utf-8" ?>
<X509SN>
  <SerialNumbers>
    <Number CA="CN=Test01CA" SN="0e9a8c9d238597ae47ef56eb7e3a0b61"/>
  </SerialNumbers>
</X509SN>

然后配置客户端x509证书能访问的服务资源权限(RoleResourceConfig.xml)

<?xml version="1.0" encoding="utf-8" ?>
<ResourceConfig>
  <!--TEST1-->
  <Role Name="Test01CA">
    <!--格式：地址+方法名；all表示有权限访问该地址下所有的服务方法-->
    <Resource>http://tempuri.org/IHiService/all</Resource>
    <!--格式：地址+方法名；all表示有权限访问该地址下所有的服务方法-->
    <Resource>http://tempuri.org/IHelloService/all</Resource>
  </Role>
  <!--TEST2-->
  <Role Name="Test02CA">
    <!--格式：地址+方法名；all表示有权限访问该地址下所有的服务方法-->
    <Resource>http://tempuri.org/INiHaoService/all</Resource>
  </Role>
</ResourceConfig>

最后一项，配置服务传说中的ABC

直接上web.config

<?xml version="1.0" encoding="utf-8"?>

到此编写服务端代码完成。

继续客户端的，比较简单：

直接引用服务，修改一下配置

            Console.ReadLine();
        }
    }

现在进入运行阶段

1.先将服务端启动,再启动客户端

2.出结果

。。。。。
