SoapHeader的使用

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
        /// <summary>  
        /// 用户名  
        /// </summary>  
        public string UserName
        {
            get { return strUserName; }
            set { strUserName = value; }
        }
        /// <summary>  
        /// 密码  
        /// </summary>  
        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
{
    /// <summary>
    /// WebService1 的摘要说明
    /// </summary>
    [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
    {
        /// <summary>  
        /// 检测是否正确登录  
        /// </summary>  
        /// <returns></returns>  
        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();
