在WebService中使用简单的自定义SoapHeader

1.新建专案及加入Web服务 WebServiceA
2.在WebServiceA.cs中加入新的public class MySOAPHeader
3.修改WebServiceA的HelloWorld() 添加SoapHeader
4.加入Web引用 及 新建测试页面
5.测试页面的按钮事件
================================

1.新建专案及加入Web服务 WebServiceA

2.在WebServiceA.cs中加入新的public class MySOAPHeader
-----------------------------------------------------
public class MySOAPHeader : System.Web.Services.Protocols.SoapHeader
{
    public string UserPWD;
    public string UserName;

    public bool IsValidUser()
    {
        string strUserName = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile("userName", "md5");
        string strUserPWD = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile("userPWD", "md5");
        if ( (UserName == strUserName) && (UserPWD == strUserPWD))
        {
            return true;
        }
        else
        {
            return false;
        }
    }
}

3.修改WebServiceA的HelloWorld() 添加SoapHeader
----------------------------------------------
/// <summary>
/// WebServiceA 的摘要说明
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class WebServiceA : System.Web.Services.WebService {

    public WebServiceA ()
    {
        //如果使用设计的组件，请取消注释以下行
        //InitializeComponent();
    }

    public MySOAPHeader userSOAPHeader ;

    [WebMethod, SoapHeader("userSOAPHeader")]   
    public string HelloWorld()
    {
        if (userSOAPHeader.IsValidUser())
        {
            return "Hello World";
        }
        else
        {
            return "Sorry";
        }
    }   
}

4.加入Web引用 及 新建测试页面

5.测试页面的按钮事件
-------------------
protected void Button1_Click(object sender, EventArgs e)
{
    //
    string strUserName = this.txt_UserName.Text.Trim();
    strUserName = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(strUserName, "md5");
    string strUserPWD = this.txt_UserPWD.Text.Trim();
    strUserPWD = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(strUserPWD, "md5");
    //
    localhost.WebServiceA wsA = new localhost.WebServiceA();
    //
    localhost.MySOAPHeader userSOAPHeader = new localhost.MySOAPHeader();
    userSOAPHeader.UserName = strUserName;
    userSOAPHeader.UserPWD = strUserPWD;
    //
    wsA.MySOAPHeaderValue = userSOAPHeader;
    string strReturn = wsA.HelloWorld();
    //
    this.TextBox1.Text = strReturn;
}
