WebService通过SOAP头进行身份验证

1、自定义soapheader
namespace WebService2
{
    ///

    /// Service1 的摘要说明
    ///

    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(COnformsTo= WsiProfiles.BasicProfile1_1)]
    //[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 Service1 : System.Web.Services.WebService
    {
        public SecurityHeader currentUser;

        public Service1()
        {
            //如果使用设计的组件，请取消注释以下行
            //InitializeComponent();
        }
        [WebMethod, SoapHeader("currentUser")]
        public string GetResult(string queryString)
        {
            if (ValidateUser(currentUser.UserName, currentUser.UserPass))
            {
                return queryString;
            }
            else
            {
                return "您不能使用该服务";
            }
        }
       //判断逻辑
        public bool ValidateUser(string user, string pass)
        {
            if (user.Equals("user") && pass.Equals("user"))
                return true;
            else
                return false;
        }
    }
    //继承SoapHeader
    public class SecurityHeader : System.Web.Services.Protocols.SoapHeader
    {
        public string UserName;
        public string UserPass;
    }
}
2、客户端调用web服务,现将webService引用到客户端程序
 private void button1_Click(object sender, EventArgs e)
        {
            //先定义soapheader
            Text_WebService.localhost.SecurityHeader header = new Text_WebService.localhost.SecurityHeader();

            header.UserName =textBox1.Text;
            header.UserPass =textBox2.Text;

            Text_WebService.localhost.GetResultRequest service = new Text_WebService.localhost.GetResultRequest();
            service.SecurityHeader =header;

            Text_WebService.localhost.Service1SoapClient result = new Text_WebService.localhost.Service1SoapClient();
            //result.GetResult(header, "123")
           //调用服务器端的方法
            MessageBox.Show(result.GetResult(header, "123"));
        }
