使用SoapHeader对WebService进行身份验证

1.新建CheckUserSoapHeader

 public class CheckUserSoapHeader : SoapHeader
    {
        public string UserName { get; set; }
        public string Password { get; set; }

        public CheckUserSoapHeader()
        {
        }

        public CheckUserSoapHeader(string userName,string password)
        {
            UserName = userName;
            Password = password;
        }

        public  bool CheckLogin()
        {
            return UserName == "Admin" && Password == "888888";
        }
    }

2.添加webServices引用

    public class TestWebService : System.Web.Services.WebService
    {
        public CheckUserSoapHeader CheckUser;

        [SoapHeader("CheckUser")]
        [WebMethod(Description="校验用户名和密码，返回登录信息",EnableSession=true)]
        public string GetLoginMessage()
        {
            if (CheckUser.CheckLogin())
            {
                return "登录成功！";
            }
            return "登录失败！";
        }

    }

 3.前台调用

      protected void btnLogin_Click(object sender, EventArgs e)
        {
            CheckUserWebservice.CheckUserSoapHeader header = new CheckUserWebservice.CheckUserSoapHeader();
            header.UserName = txtName.Text;
            header.Password = txtPassword.Text;
            CheckUserWebservice.TestWebServiceSoapClient client = new CheckUserWebservice.TestWebServiceSoapClient();
            lblMessage.Text = client.GetLoginMessage(header);
        }

4.整体效果
