1、新建Account,AccountService,SessionWrapper
public class Account
{
public Guid AccountId { get; set; }
public string Username { get; set; }
public string Email { get; set; }
public List<string> Roles { get; set; }
}
public Account GetAccountByUsername(string username)
{
Account result = new Account();
result.AccountId = Guid.NewGuid();
result.Email = username + "@hotmail.com";
result.Username = username;
result.Roles = new List<string>() { "Administrator", "Publisher", "Dude" };
return result;
}
public static class SessionWrapper
{
private const string c_account = "Account";
public static Account Account
{
get { return GetObjectFromSession(c_account) as Account; }
set
{
if (value == null)
ClearItemFromSession(c_account);
else
SetItemInSession(value, c_account);
}
}
private static string GetStringFromSession(string key)
{
return GetObjectFromSession(key).ToString();
}
private static int GetIntFromSession(string key)
{
return (int)GetObjectFromSession(key);
}
private static object GetObjectFromSession(string key)
{
return HttpContext.Current.Session[key];
}
private static void SetItemInSession(object item, string key)
{
HttpContext.Current.Session.Add(key, item);
}
private static void ClearItemFromSession(string key)
{
HttpContext.Current.Session.Remove(key);
}
}
2、在AccountModels.cs查找方法SignIn,SignOut把他们替换成如下
public void SignIn(string userName, bool createPersistentCookie)
{
if (String.IsNullOrEmpty(userName))
throw new ArgumentException("Value cannot be null or empty.", "userName");
FormsAuthentication.SetAuthCookie(userName,createPersistentCookie);
SessionWrapper.Account = new AccountService().GetAccountByUsername(userName);
}
public void SignOut()
{
FormsAuthentication.SignOut();
SessionWrapper.Account = null;
}
3、在Site.Master中<% Html.RenderPartial("LogOnUserControl"); %>的下面添加当前用户名称的显示
<div id="logindisplay">
<% Html.RenderPartial("LogOnUserControl"); %>
<%= MvcApplication1.Models.SessionWrapper.Account != null ? "Welcome " + MvcApplication1.Models.SessionWrapper.Account.Username + "from session wrapper!" : ""%>
</div>
本文介绍了一个简单的ASP.NET应用中实现用户认证及会话管理的方法。具体包括创建Account模型来存储用户信息,使用SessionWrapper类进行会话管理,并通过修改SignIn和SignOut方法实现基于Forms的身份验证。此外,还展示了如何在页面上显示当前登录用户的用户名。
