Asp.Net MVC 自定义登录过滤器
1、新建类BaseController用于统一所有控制器继承扩展，方便扩展登录等过滤器。示例如下：
using CloudWave.JustBeHere.JBH_H5.Controllers.Attribute; using CloudWave.JustBeHere.JBH_H5.Controllers.Authorization; using CloudWave.JustBeHere.JBH_H5.Models.User; using CloudWave.JustBeHere.Web; using Jil; using System; using System.Collections.Generic; using System.Linq; using System.Text.RegularExpressions; using System.Web; using System.Web.Mvc; using static CloudWave.JustBeHere.JBH_H5.Models.Commn.BaseModel; namespace CloudWave.JustBeHere.JBH_H5.Controllers { [Auth] [ResultFilter] #if (!DEBUG) [Error] #endif public class BaseController : Controller { public Authentication authentication = Authentication.Instance; public bool IsLogin { get { //return true; return authentication.IsLogin; } } public LoginResult Operator { get { return authentication.CurrentUser; } } private string _hostName; /// <summary> /// 获取请求的域名 /// </summary> public string HostName { get { if (string.IsNullOrEmpty(_hostName)) { var url = Request.Url.ToString(); // http(s)?://([\w-]+\.{0,1})+\:{0,1}[0-9]{0,1}[\w-]? var reg = new Regex(@"//([\w-]+\.{0,1})+\:{0,1}[0-9]{0,1}[\w-]+/?"); var result = reg.Match(url, 0).Value; _hostName = result; } return _hostName; } } private string _hostFullName; /// <summary> /// 获取请求的域名全称（含请求协议） /// </summary> public string HostFullName { get { if (string.IsNullOrEmpty(_hostFullName)) { var url = Request.Url.ToString(); // http(s)?://([\w-]+\.{0,1})+\:{0,1}[0-9]{0,1}[\w-]? var reg = new Regex(@"http(s)?://([\w-]+\.{0,1})+\:{0,1}[0-9]{0,1}[\w-]+/?"); var result = reg.Match(url, 0).Value; _hostFullName = result; } return _hostFullName; } } /// <summary> /// 是否为手机端访问 /// </summary> public bool IsMobile { get { var uAgent = Request.ServerVariables["HTTP_USER_AGENT"]; var b = new Regex(@"android.+mobile|avantgo|bada\/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|iris|kindle|lge |maemo|midp|mmp|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|plucker|pocket|psp|symbian|treo|up\.(browser|link)|vodafone|wap|windows (ce|phone)|xda|xiino", RegexOptions.IgnoreCase | RegexOptions.Multiline); var v = new Regex(@"1207|6310|6590|3gso|4thp|50[1-6]i|770s|802s|a wa|abac|ac(er|oo|s\-)|ai(ko|rn)|al(av|ca|co)|amoi|an(ex|ny|yw)|aptu|ar(ch|go)|as(te|us)|attw|au(di|\-m|r |s )|avan|be(ck|ll|nq)|bi(lb|rd)|bl(ac|az)|br(e|v)w|bumb|bw\-(n|u)|c55\/|capi|ccwa|cdm\-|cell|chtm|cldc|cmd\-|co(mp|nd)|craw|da(it|ll|ng)|dbte|dc\-s|devi|dica|dmob|do(c|p)o|ds(12|\-d)|el(49|ai)|em(l2|ul)|er(ic|k0)|esl8|ez([4-7]0|os|wa|ze)|fetc|fly(\-|_)|g1 u|g560|gene|gf\-5|g\-mo|go(\.w|od)|gr(ad|un)|haie|hcit|hd\-(m|p|t)|hei\-|hi(pt|ta)|hp( i|ip)|hs\-c|ht(c(\-| |_|a|g|p|s|t)|tp)|hu(aw|tc)|i\-(20|go|ma)|i230|iac( |\-|\/)|ibro|idea|ig01|ikom|im1k|inno|ipaq|iris|ja(t|v)a|jbro|jemu|jigs|kddi|keji|kgt( |\/)|klon|kpt |kwc\-|kyo(c|k)|le(no|xi)|lg( g|\/(k|l|u)|50|54|\-[a-w])|libw|lynx|m1\-w|m3ga|m50\/|ma(te|ui|xo)|mc(01|21|ca)|m\-cr|me(di|rc|ri)|mi(o8|oa|ts)|mmef|mo(01|02|bi|de|do|t(\-| |o|v)|zz)|mt(50|p1|v )|mwbp|mywa|n10[0-2]|n20[2-3]|n30(0|2)|n50(0|2|5)|n7(0(0|1)|10)|ne((c|m)\-|on|tf|wf|wg|wt)|nok(6|i)|nzph|o2im|op(ti|wv)|oran|owg1|p800|pan(a|d|t)|pdxg|pg(13|\-([1-8]|c))|phil|pire|pl(ay|uc)|pn\-2|po(ck|rt|se)|prox|psio|pt\-g|qa\-a|qc(07|12|21|32|60|\-[2-7]|i\-)|qtek|r380|r600|raks|rim9|ro(ve|zo)|s55\/|sa(ge|ma|mm|ms|ny|va)|sc(01|h\-|oo|p\-)|sdk\/|se(c(\-|0|1)|47|mc|nd|ri)|sgh\-|shar|sie(\-|m)|sk\-0|sl(45|id)|sm(al|ar|b3|it|t5)|so(ft|ny)|sp(01|h\-|v\-|v )|sy(01|mb)|t2(18|50)|t6(00|10|18)|ta(gt|lk)|tcl\-|tdg\-|tel(i|m)|tim\-|t\-mo|to(pl|sh)|ts(70|m\-|m3|m5)|tx\-9|up(\.b|g1|si)|utst|v400|v750|veri|vi(rg|te)|vk(40|5[0-3]|\-v)|vm40|voda|vulc|vx(52|53|60|61|70|80|81|83|85|98)|w3c(\-| )|webc|whit|wi(g |nc|nw)|wmlb|wonu|x700|yas\-|your|zeto|zte\-", RegexOptions.IgnoreCase | RegexOptions.Multiline); return b.IsMatch(uAgent) || v.IsMatch(uAgent.Substring(0, 4)); } } } }
2、新建类Authentication用于管理Session、Cookie等信息。示例如下:
using CloudWave.JustBeHere.JBH_H5.Models.User; using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Security; namespace CloudWave.JustBeHere.JBH_H5.Controllers.Authorization { public class Authentication { public const string UserSessionKey = "UserInfo"; private Authentication() { } public static Authentication Instance { get { return new Authentication(); } } /// <summary> /// 写入验证信息 /// </summary> /// <param name="uInfo"></param> /// <param name="isPersistent">是否保存</param> public void SetAuth(LoginResult uInfo, bool isPersistent) { string token = uInfo.Id + "|" + uInfo.Token; //将用户ID和角色写入Cookie FormsAuthentication.SetAuthCookie(token, isPersistent, FormsAuthentication.FormsCookiePath); HttpCookie authCookie = FormsAuthentication.GetAuthCookie(token, isPersistent); FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(authCookie.Value); //FormsAuthentication.RedirectFromLoginPage(ticket.Name, true); FormsAuthenticationTicket newTicket = new FormsAuthenticationTicket(ticket.Version, ticket.Name, ticket.IssueDate, DateTime.Now.AddDays(30), ticket.IsPersistent, ""); authCookie.Value = FormsAuthentication.Encrypt(newTicket); HttpContext.Current.Response.AddHeader("P3P", "CP=CAO PSA OUR");//解决ie js跨域调用 HttpContext.Current.Response.Cookies.Add(authCookie); SetSession(uInfo); } /// <summary> ///保存用户状态 /// </summary> /// <param name="uInfo"></param> public void SetSession(LoginResult uInfo) { HttpContext.Current.Session[UserSessionKey] = uInfo; } /// <summary> ///保存用户状态 /// </summary> /// <param name="uid"></param> public void SetSession(int uid) { bool setFlag = false; if (HttpContext.Current.Session == null) { throw new ArgumentNullException("SessionState Failed"); } if (HttpContext.Current.Session[UserSessionKey] == null) { setFlag = true; } else { //得到用户信息 LoginResult sulr = HttpContext.Current.Session[UserSessionKey] as LoginResult; if (sulr.Id != uid) setFlag = true; } if (setFlag) { try { //var u = GetUserInfo(); //if (u != null) //{ // HttpContext.Current.Session[UserSessionKey] = u; //} new RedirectToRouteResult("default", new System.Web.Routing.RouteValueDictionary(new { action = "Index", controller = "Home" })); } catch { } } } private LoginResult GetUserInfo() { var client = new Api(WebCommon.ApiUrl, WebCommon.ActiveUser, WebCommon.ApiToken); LoginResult slr = new LoginResult(); client.Request.Header.Cmd = "api/staffuser/getstaffuserinfo"; slr = client.ExecutePost<LoginResult>(); if (client.Response.Header.statusCode == 1000) { return slr; } else { return null; } } /// <summary> /// 登出 /// </summary> public void SignOut() { FormsAuthentication.SignOut(); HttpContext.Current.Session.Clear(); } public bool IsLogin { get { return HttpContext.Current != null ? HttpContext.Current.Request.IsAuthenticated : false; } } /// <summary> /// 当前用户信息 /// </summary> public LoginResult CurrentUser { get { if (!IsLogin) { return null; } int uid; if (int.TryParse(HttpContext.Current.User.Identity.Name.Split('|')[0], out uid)) { if (HttpContext.Current.Session[UserSessionKey] == null) { SetSession(uid); } return HttpContext.Current.Session[UserSessionKey] as LoginResult; } return null; } } //public void RefreshInfo() //{ // UsersExtensionInfo u = UsersService.GetById(HttpContext.Current.User.Identity.Name); // u.ImName = UsersService.GetImName(u.TTUserId); // HttpContext.Current.Session[UserSessionKey] = UserInfoDec(u); //} } }
3、新建类AuthAttribute,继承AuthorizeAttribute类。示例如下：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; namespace CloudWave.JustBeHere.JBH_H5.Controllers.Attribute { /// <summary> /// 登录过滤器 /// </summary> public class AuthAttribute : AuthorizeAttribute { public override void OnAuthorization(AuthorizationContext filterContext) { var controller = filterContext.Controller as BaseController; if (controller.IsLogin) { filterContext.Controller.ViewBag.UserInfo = controller.Operator?.Id; // filterContext.Controller.ViewBag.PartnerName = controller.Operator?.PartnerName; } else { filterContext.Controller.ViewBag.UserInfo = ""; // filterContext.Controller.ViewBag.PartnerName = ""; } if (!filterContext.ActionDescriptor.IsDefined(typeof(AllowAnonymousAttribute), true) && !filterContext.ActionDescriptor.ControllerDescriptor.IsDefined(typeof(AllowAnonymousAttribute), true)) { if (!controller.IsLogin) { //if (filterContext.HttpContext.Request.IsAjaxRequest()) //{ // filterContext.Result = new JsonResult // { // Data = "needlogin", // JsonRequestBehavior = JsonRequestBehavior.AllowGet // }; //} //else //{ // string reutrnUrl = filterContext.RequestContext.HttpContext.Request.RawUrl; // filterContext.Result = new RedirectToRouteResult("default", new System.Web.Routing.RouteValueDictionary(new { action = "index", controller = "Home", returnUrl = reutrnUrl })); //} string reutrnUrl = filterContext.RequestContext.HttpContext.Request.RawUrl; filterContext.Result = new RedirectToRouteResult("default", new System.Web.Routing.RouteValueDictionary(new { action = "index", controller = "Home", returnUrl = reutrnUrl })); } } //if (!AuthorizeCore(filterContext.HttpContext)) { // HandleUnauthorizedRequest(filterContext); //} else { // filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache); //} } } }
4、在Web.config的节点system.web下新增如下节点配置：
<authentication mode="Forms"> <forms loginUrl="/Home/Index" timeout="43200"></forms> </authentication>
5、返回信息过滤器：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Security; namespace CloudWave.JustBeHere.JBH_H5.Controllers.Attribute { /// <summary> /// 请求返回结果过滤器 /// </summary> public class ResultFilterAttribute : ActionFilterAttribute { public override void OnResultExecuting(ResultExecutingContext filterContext) { if (filterContext.Result is ViewResult) { var controller = (BaseController)filterContext.Controller; FormsAuthentication.SignOut(); HttpContext.Current.Session.Clear(); } base.OnResultExecuting(filterContext); } } }
