为WebService添加身份验证的两种方法

方法一：SoapHeader

辅助类：MySoapHeader 

    //SoapHeader 添加引用
    using System.Web.Services.Protocols;
    
    #region 配置登录标头
    
    public class MySoapHeader:SoapHeader
    {
        private string _strUserName = string.Empty;
        private string _strPassWord = string.Empty;

        #region 构造方法
        public MySoapHeader() { }

        public MySoapHeader(string userName, string passWord)
        {
            _strUserName = userName;
            _strPassWord = passWord;
        }
        #endregion


        #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


        #region 检测是否正常登录
        public bool CheckLogin()
        {
            if (_strUserName == "hkl" && _strPassWord == "123")
            {
                return true;
            }
            else return false;
        }
        #endregion

    }

    #endregion

WebService代码

        public MySoapHeader myHeader = new MySoapHeader();

        [System.Web.Services.Protocols.SoapHeader("myHeader")]
        [WebMethod(Description = "判断用户是否开通", EnableSession = true)]
        public string GetValue(string strInputValue)
        {
            if (myHeader.CheckLogin())
            {
                string strReturnValue = strInputValue + "@身份验证已通过";
                return strReturnValue;
            }
            else return "身份无效，请重试！";
        }

新建一个web网页并添加web引用，在pageload方法中添加如下代码

            localhost1.MySoapHeader myHeader = new localhost1.MySoapHeader();
            myHeader.UserName = "hkl";
            myHeader.PassWord = "123";

            localhost1.Service1 myTest = new localhost1.Service1();
            myTest.MySoapHeaderValue = myHeader;
            Response.Write(myTest.GetValue("This's my test Application for SoapHeader."));

运行即可查看结果。

方法二：Session

　　WebService代码

        [WebMethod(Description = "检测是否通过验证", EnableSession = true)]
        public bool CheckLogin(string strUserName, string strPassWord)
        {
            if (strUserName.Equals("xxx") && strPassWord.Equals("123"))
            {
                Session["LoginState"] = true;
            }
            else Session["LoginState"] = false;

            return (bool)Session["LoginState"];
        }

        [WebMethod(Description = "测试连接", EnableSession = true)]
        public string GetValue(string strInputValue)
        {
            if (Session["LoginState"] == null || Session["LoginState"].Equals(false))
            {
                return "无效身份，请重试！";
            }
            else
            {
                string strReturnValue = strInputValue + "@身份验证已通过";
                return strReturnValue;
            }
        }

新建一个web网页并添加web引用，在pageload方法中添加如下代码

            localhost2.Service2 myTest = new localhost2.Service2();
            myTest.CookieContainer = new System.Net.CookieContainer();
            if (myTest.CheckLogin("xxx", "123"))
            {
                Response.Write(myTest.GetValue("This is my test application for session."));
            }

运行即可查看结果。
