1,使用SoapHeader传递和验证用户
Web Service端的代码:
1.1先创建一个继承自System.Web.Services.Protocols.SoapHeader
CredentialSoapHeader类:
public class CredentialSoapHeader : SoapHeader
{
private string _userName ;；
private string _userPassword ;；
public string UserName
{
get { return _userName ;； }
set { _userName = value ;； }
}
public string UserPassword
{
get { return _userPassword ;； }
set { _userPassword = value ;； }
}
}
1.2创建对外发布的Web Service方法
public class MyService : System.Web.Services.WebService
{
private CredentialSoapHeader m_credentials ;；
public CredentialSoapHeader Credentails
{
get { return m_credentials ;； }
set { m_credentials = value ;； }
}
//对外发布的服务
[WebMethod(BufferResponse = true,Description = "欢迎方法" ,CacheDuration = 0,EnableSession=false,
MessageName = "HelloFriend",TransactionOption = TransactionOption.Required)]
[SoapHeader("Credentails")]
public string Welcome(string userName)
{
this.VerifyCredential(this) ;；
return "Welcome " + userName ;；
}
//验证是否合法
private void VerifyCredential(MyService s)
{
if ( s.Credentails == null || s.Credentails.UserName == null || s.Credentails.UserPassword == null )
{
throw new SoapException("验证失败",SoapException.ClientFaultCode,"Security") ;；
}
//在这里可以进一步进行自定义的用户验证
}
}
创建使用MyService的客户端(本处使用WinForm来做实例)
先把MyService的引用添加进来
public class ClientForm : System.Windows.Forms.Form
{
public ClientForm()
{
MyService s = new MyService() ;；
this.InitWebServiceProxy(s) ;；
string temp = s.Welcome("test") ;；
MessageBox.Show(temp) ;；
}
private void InitWebServiceProxy(MyService s)
{
CredentialSoapHeader soapHeader = new CredentialSoapHeader() ;；
soapHeader.UserName = "test" ;；
soapHeader.UserPassword = "test" ;；
s.CredentialSoapHeaderValue = soapHeader ;；
string urlSettings = null ;； //这里可以从配置文件中获取
if (urlSettings != null )
{
s.Url = urlSettings ;；
}
s.Credentials = (System.Net.NetworkCredential)CredentialCache.DefaultCredentials ;；
}
}
2,使用验证票(AuthorizationTicket)
using System.Web.Security ;；
[WebMethod()]
public string GetAuthorizationTicket(string userName , string password)
{
//这里可以做一些自定义的验证动作，比如在数据库里验证用户的合法性等
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(userName, false, timeOut) ;；
string encryptedTicket = FormsAuthentication.Encrypt(ticket) ;；
Context.Cache.Insert(encryptedTicket, userName, null, DateTime.Now.AddMinutes(timeout), TimeSpan.Zero) ;；
return encryptedTicket ;；
}
private bool IsTicketValid(string ticket, bool IsAdminCall)
{
if (ticket == null || Context.Cache[ticket] == null)
{
// not authenticated
return false;；
}
else
{
//这里再做一些验证，比如在数据库里验证用户的合法性等
}
}
[WebMethod()]
public Book GetBookByBookId(int bookId)
{
if (IsTicketValid)
{
//验证通过才可以执行特定操作了
}
