前段时间用MVC + Redis 做session做了个简单的单点Web站。真是日了狗的问题多。
今天正好睡不着，做个备忘笔记>_<
实现方法很简单，无非就是从重载个Controller或 做一个ActionFilterAttribute就可以达到目的。
下面贴一个Controller的代码实现，ActionFilterAttribute实现方式类似：
这里我为了图方便用了servicestack.redis 虽然最新的免费版本 有很大的性能限制（真坑爹）。
两个Controller 类，Base用于在Action执行前填充的Account信息，一个要求必须登陆，否则调到SSO
public class BaseAccountController : Controller { protected RedisHelper.RedisHelper redisHelper { get; private set; } protected readonly static String TokenKeyCookie = "QTMAccountTokenCookie"; public BaseAccountController() { redisHelper = new RedisHelper.RedisHelper(); } ~BaseAccountController() { if (redisHelper != null) { redisHelper.Dispose(); } } protected override void OnActionExecuting(ActionExecutingContext filterContext) { var cookie = filterContext.HttpContext.Request.Cookies[TokenKeyCookie]; String token = filterContext.HttpContext.Request.QueryString["Token"]; if (cookie != null) { token = cookie.Value; var accountIndex = redisHelper.Get<AccountIndex>(token); ViewBag.CurrentAccount = accountIndex; } else if (!String.IsNullOrWhiteSpace(token)) { var accountIndex = CreateTokenCookie(token); ViewBag.CurrentAccount = accountIndex; } } /// <summary> /// 创建Token令牌的本地Cookie /// </summary> /// <param name="Token">Token令牌</param> /// <returns></returns> protected AccountIndex CreateTokenCookie(string Token) { var accountIndex = redisHelper.Get<AccountIndex>(Token); //判断是否 为有效的Token令牌 if (accountIndex == null) { return null; } //生产Token令牌的Cookie var token_cookie = new HttpCookie(TokenKeyCookie, Token) { HttpOnly = true, Secure = FormsAuthentication.RequireSSL, Path = "/", Expires = DateTime.Now.AddYears(10) }; HttpContext.Response.Cookies.Add(token_cookie); return accountIndex; }
在
/// <summary> /// 控制器的 所有Action必须 持有 有效的 Account Token令牌。 /// </summary> public class AccountAuthenController : BaseAccountController { public AccountAuthenController() : base() { } ~AccountAuthenController() { if (redisHelper != null) { redisHelper.Dispose(); } } protected override void OnActionExecuting(ActionExecutingContext filterContext) { String token = filterContext.HttpContext.Request.QueryString["Token"]; var cookie = filterContext.HttpContext.Request.Cookies[TokenKeyCookie]; if (cookie == null) { if (!String.IsNullOrWhiteSpace(token)) { //当有返回新的Token令牌时，创建一个新的Token本地Cookie var accountIndex = CreateTokenCookie(token); if (accountIndex == null) { filterContext.HttpContext.Response.Redirect(String.Format(ActionUri.Login, filterContext.HttpContext.Request.Url.AbsoluteUri)); } } else { filterContext.HttpContext.Response.Redirect(String.Format(ActionUri.Login, filterContext.HttpContext.Request.Url.AbsoluteUri)); } } else { token = cookie.Value; var accountIndex = redisHelper.Get<AccountIndex>(token); if (accountIndex == null) { //无效的Token Cookie filterContext.HttpContext.Response.Cookies[TokenKeyCookie].Expires = DateTime.Now.AddYears(-1); filterContext.HttpContext.Response.Redirect(String.Format(ActionUri.Login, filterContext.HttpContext.Request.Url.AbsoluteUri)); } } base.OnActionExecuting(filterContext); } #region Private Method #endregion }
