自定义类继承SoapHeader用户在webservice表头传递凭据

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Services.Protocols;namespace FormsAuth.WebService{    public class SoapHeaderCredential:SoapHeader    {        private string strUserName = string.Empty;        private string strPassWord = string.Empty;        public SoapHeaderCredential() { }        public SoapHeaderCredential(string username, string password)        {            this.strUserName = username;            this.strPassWord = password;        }        #region 构造 用户名|密码        /// 
          /// 用户名          /// 
          public string UserName        {            get { return strUserName; }            set { strUserName = value; }        }        /// 
          /// 密码          /// 
          public string PassWord        {            get { return strPassWord; }            set { strPassWord = value; }        }        #endregion    }}

添加接口IWebService

public interface IWebService{      SoapHeaderCredential HeaderCredential { get; set; }}

添加webservice实现IWebService接口

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Services;using System.IO;using System.Xml.Serialization;using System.Text;using System.Web.Services.Protocols;namespace FormsAuth.WebService{    /// 
    /// WebService1 的摘要说明    /// 
    [WebService(Namespace = "http://tempuri.org/")]    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]    [System.ComponentModel.ToolboxItem(false)]    // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。    // [System.Web.Script.Services.ScriptService]    public class WebService1 : System.Web.Services.WebService, IWebService    {        [WebMethod]        [SoapHeader("HeaderCredential")]        public string HelloWorld()        {            SpSoapHeader.CheckLogin(this);            return "hello word";        }        #region IWebService 成员        public SoapHeaderCredential HeaderCredential        {            get;            set;        }        #endregion    }}

SpSoapHeader用户验证

public class SpSoapHeader    {        /// 
          /// 检测是否正确登录          /// 
          /// 
               public static bool CheckLogin(IWebService service)        {            if (!(service.HeaderCredential.UserName == "user" && service.HeaderCredential.PassWord == "pass"))            {                throw new SoapException("Audit Fail", SoapException.ClientFaultCode, "Security");            }            return true;        }    }

在客户端引用webservice，实例化webservice时制定凭据

WebReferences1.WebService1 client = new FormClient.WebReferences1.WebService1();WebReferences1.SoapHeaderCredential header = new FormClient.WebReferences1.SoapHeaderCredential();header.UserName = "user";header.PassWord = "pass";client.SoapHeaderCredentialValue = header;string ss = client.HelloWorld();
