化零为整WCF(17) - 安全(Security)

作者：webabcd


介绍
WCF(Windows Communication Foundation) - 安全(Security)：本文以用户名和密码做验证，通过X.509证书做加密为例


示例
1、证书
setup.bat

makecert -sr LocalMachine -ss My -a sha1 -n CN=Webabcd -sky exchange -pe
certmgr -add -r LocalMachine -s My -c -n Webabcd -s TrustedPeople

2、服务
IHello.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using System.ServiceModel;

namespace WCF.ServiceLib.Security
{
    /**//// <summary>
    /// IHello接口
    /// </summary>
    [ServiceContract]
    public interface IHello
    {
        /**//// <summary>
        /// 打招呼方法
        /// </summary>
        /// <param name="name">人名</param>
        /// <returns></returns>
        [OperationContract]
        string SayHello(string name);
    }
}

Hello.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using System.ServiceModel;

namespace WCF.ServiceLib.Security
{
    /**//// <summary>
    /// Hello类
    /// </summary>
    public class Hello : IHello
    {
        /**//// <summary>
        /// 打招呼方法
        /// </summary>
        /// <param name="name">人名</param>
        /// <returns></returns>
        public string SayHello(string name)
        {
            return "Hello: " + name;
        }
    }
}

CustomNamePasswordValidator.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using System.ServiceModel;

namespace WCF.ServiceLib.Security
{
    /**//// <summary>
    /// 自定义的用户名/密码验证类
    /// </summary>
    public class CustomNamePasswordValidator : System.IdentityModel.Selectors.UserNamePasswordValidator
    {
        /**//// <summary>
        /// 验证指定的用户名和密码
        /// </summary>
        /// <param name="userName">要验证的用户名</param>
        /// <param name="password">要验证的密码</param>
        public override void Validate(string userName, string password)
        {
            if (!(userName == "webabcd" && password == "webabcd"))
            {
                throw new FaultException("用户名或密码不正确");
            }
        }
    }
}

运行结果：
单击"btnSayHello"按钮，显示"Hello: webabcd"。经过加密的用户名和密码放在SOAP头中传输。
