//url加密与解密
string res1 = HttpUtility.UrlEncode("7Z2K5Lgk/iI="); //值是7Z2K5Lgk%2fiI%3d string res2 = HttpUtility.UrlEncode(res1); //值是: 7Z2K5Lgk%252fiI%253d string res3 = HttpUtility.UrlDecode(res2); //值是7Z2K5Lgk%2fiI%3d string res4 = HttpUtility.UrlDecode(res3);
//值是7Z2K5Lgk/iI=
using GiftWeb.Dao; using System; using System.Collections.Generic; using System.Linq; using System.Text.RegularExpressions; using System.Web; using System.Web.Mvc; namespace GiftWeb.Controllers { public class LoginController : Controller { // // GET: /Login/ public ActionResult Index() { //1.当session自动过期 string returnUrl = Request.RawUrl; string url = string.Empty; if (!Regex.IsMatch(returnUrl, @"^/Login/Index")) { url = HttpUtility.UrlEncode(returnUrl); } //获取退出时的ulr地址 url = Request["returnUrl"]; ViewBag.returnUrl = url; return View(); } [HttpPost] public ActionResult Index(string loginname, string password) { using (GiftDBEntities db = new GiftDBEntities()) { var userinfo = db.SysUserInfo.Where(u => u.LoginName == loginname && u.Password == password).FirstOrDefault(); if (userinfo == null) { ViewBag.msg = "登录名或密码错误"; return View(); } else { //获取退出时的ulr地址 string url = Request["returnUrl"]; //对url解密 string result = HttpUtility.UrlDecode(url); Session["sysuserInfo"] = userinfo; if (string.IsNullOrEmpty(url)) { return RedirectToAction("Index", "TopicInfo"); } else { return RedirectPermanent(result); } } } } public ActionResult Logout() { //获取当前的url string url = Request["returnUrl"]; //将url加密 string result = HttpUtility.UrlEncode(url); //让session过期 Session.Abandon(); //跳转到登录页面 return Content(result); } } }
<script type="text/javascript"> function logout() { var url = "@Request.RawUrl"; alert(url); $.post("/Login/Logout?returnUrl="+url, function (data) { if (data != null) { window.location = "/Login/Index?returnUrl=" + data; } }); } </script>
URL的获取很简单，ASP.NET通用：
【1】获取 完整url
（协议名+域名+虚拟目录名+文件名+参数）
string url=Request.Url.ToString();
【2】获取 虚拟目录名+页面名+参数：
string url=Request.RawUrl;
(或 string
url=Request.Url.PathAndQuery;)
【3】获取
虚拟目录名+页面名：
string url=HttpContext.Current.Request.Url.AbsolutePath;
(或
string url= HttpContext.Current.Request.Path;)
【4】获取 域名：
string
url=HttpContext.Current.Request.Url.Host;
【5】获取 参数：
string url=
HttpContext.Current.Request.Url.Query;
【6】获取 端口：
Request.Url.Port
二、当前controller、action的获取
RouteData.Route.GetRouteData(this.HttpContext).Values["controller"]
RouteData.Route.GetRouteData(this.HttpContext).Values["action"]
或
RouteData.Values["controller"]
RouteData.Values["action"]
如果在视图中可以用
ViewContext.RouteData.Route.GetRouteData(this.Context).Values["controller"]
ViewContext.RouteData.Route.GetRouteData(this.Context).Values["action"]
或
ViewContext.RouteData.Values["controller"]
ViewContext.RouteData.Values["action"]
