webservice 第一节 .net SoapHeader验证

　　在工作中经常用到webservice,在.net 开发中经常用到webservice，在java开发经常用到cxf.

　　今天闲置没事就介绍下 .net webservice中常用到 soapheader token验证和重载。当然在正常使用中不太建议使用重载。

下面的列表概述接收和处理 SOAP 标头的基本步骤：

1. 创建一个从 SoapHeader 派生的类，表示传入 SOAP 标头的数据。

　　　　

using System.Web.Services.Protocols;

namespace WService
{
    /// <summary>
    /// Fireran
    /// </summary>
    public class MySoapHeader : SoapHeader
    {

        public MySoapHeader()
        {

        }

        /// <summary>
        /// username
        /// </summary>
        public string UserName { get; set; }

        /// <summary>
        /// ip
        /// </summary>
        public string Ip { get; set; }

        /// <summary>
        /// token
        /// </summary>
        public string Token { get; set; }
    }
}

　　2. XML Web services 方法将 myHeader 成员指定为 MemberName 属性，接收 XML Web services 方法的 MyHeader SOAP 标头的内容。

　　　　　

  private MySoapHeader _mySoapHeader;
        public MySoapHeader mySoapHeader
        {
            get { return _mySoapHeader; }
            set { _mySoapHeader = value; }
        }

      　 [WebMethod]
        [SoapHeader("mySoapHeader")]
        public string GetSayHello(long id)
        {
            string result = "";
            if (mySoapHeader==null)
            {
                result = "token is nulll";
            }
            else
            {
                if (mySoapHeader.Token.Equals(""))
                {
                    result = "hello world" + id;
                }
                else
                {
                    result = "token is err";
                }
            }

            return result;

        }

　　　3. 发布webservice  利用wsdl 工具生成代理类

        }
    }
}

　　4. 在代理类中添加 token 信息  修改代理类中的构造方法 如下

public FireRan() {
　　MySoapHeaderValue = new MySoapHeader();
　　this.MySoapHeaderValue.Token = "123456";
　　this.Url = "http://localhost:54540/FireRan.asmx";
}

　　　　

　　5. 添加测试类进行测试

 [TestFixture]
   public class FireRanTest
    {
        [Test]
        public void  Read()
        {
            using(FireRan fireRan = new FireRan())
            {
                Console.Write(fireRan.GetSayHello());
            }

        }
    }

　　　　6. 运行结果

　　

　　在项目中为了服务安全对token和ip进行授权是很有必要的。但是在项目中有发现token 和 ip 很难精确的控制服务的访问。建议在实际开发中可以根据自己业务添加动态的验证方式，和每个业务独立的业务类型。这样可以更加精确的控制访问着的访问权限和权限降级。
