webserviceSoapHeader头部认证

SoapHeader为webservice的头部信息，头部信息可用于相关的验证等功能

在webservice服务端定义SoapHeader类，继承自SoapHeader

   /// <summary>
    /// 用于webservice认证
    /// </summary>
    public class CertficateSoapHeader : SoapHeader
    {
        /// <summary>
        /// 属性
        /// </summary>
        public string UserName { get; set; }
        public string PassWord { get; set; }      
        public CertficateSoapHeader() { }
        /// <summary>
        /// 构造函数认证
        /// </summary>
        /// <param name="userName">用户名</param>
        /// <param name="passWord">密码</param>
        public CertficateSoapHeader(string userName, string passWord)
        {
            this.UserName = userName;
            this.PassWord = passWord;
        }
    }

服务类中：

public class BotWebService : System.Web.Services.WebService
    {

        public CertficateSoapHeader soapHeader;

        [SoapHeader("soapHeader",Direction=SoapHeaderDirection.In)]//这里的声明必需和上次的名字对应
        [WebMethod]
        public string HelloWorld()
        {

                     if (myHeader.UserName == null || myHeader.PassWord == null)
                        {                          
                            break;
                        }

                        if (myHeader.UserName.Equals("LY") && myHeader.PassWord.Equals("LY"))
                        {
                             return "Hello World";

                            break;
                        }

else

{

  throw new SoapHeaderException("认证失败", SoapException.ClientFaultCode);}

      }

客户端调用：

   BotWebServiceSoapClient service = new BotWebServiceSoapClient();
                // BotWebService service = new BotWebService();

               
                CertficateSoapHeader header = new CertficateSoapHeader();
                header.UserName = "LY";
                header.PassWord = "LY";
                service.CertficateSoapHeaderValue = header;
                string aa = service.HelloWorld(header);

这样就能正常返回，如果不定义,就不能认证

这种方式实现起来比较简单，但在webservice中每个webmethod方法中都必须加上if。。else。。的判断条件，使用起来不够灵活，从软件设计的角度讲藕合性太强，

一般的权限认证和日志认证，一般会用动态代理来处理相关问题. 而在webservice中一般用SoapExtensionAttribute和SoapExtension方法来处理。
