net mvc中实现记录用户登陆信息(记住登陆效果)

现记录用户登陆信息(记住登陆效果)cookie

本文讲述了使用cookies实现网站记住登陆效果,效果以下:网站

主要实现方法,当用户选择记住登陆时创建cookies保存用户名和用户密码,当用户登陆不选择记住登陆时,从新创建一个cookies,设置以过时,并将保存用户名、密码的子cookies赋null值,代码以下:spa

//记住登陆名密码blog

if (SAVAUSERID == "on")input

{it

     HttpCookie cookie = new HttpCookie("COOKIE_NAME_FOR_USER");cookies

     cookie.Expires = DateTime.Now.AddYears(1);class

     cookie["COOKIE_USER_NAME"] = LOGINNAME;登录

     cookie["COOKIE_USER_PASS"] = LOGINPASSWORD;密码

     System.Web.HttpContext.Current.Response.Cookies.Add(cookie);

 }

 else

 {

     HttpCookie cookie = new HttpCookie("COOKIE_NAME_FOR_USER");

     cookie.Expires = DateTime.Now.AddYears(-1);

     Request.Cookies.Add(cookie);

     cookie["COOKIE_USER_NAME"] = null;

     cookie["COOKIE_USER_PASS"] = null;

     System.Web.HttpContext.Current.Response.Cookies.Add(cookie);

 }

前台页面代码:

用户名称:<input class="input" id="LOGINNAME" name="LOGINNAME" style="width:150px" type="text" value="<%=ViewData["username"]%>" />

用户密码:<input class="input" id="LOGINPASSWORD" name="LOGINPASSWORD" style="width:150px" type="password" value="<%=ViewData["userpass"]%>"/>

<input type="submit" name="button" class="button" value="登陆系统" />&nbsp;&nbsp;

<input type="checkbox" name="SAVAUSERID" id="SAVAUSERID" <%= ViewData["CHECKBOX"]%>/><span style="font-size: 12px;">记住登陆</span>

其中ViewData在进入登录页面时判断cookies的值是否为空,若是不为空就赋值,代码以下:

HttpCookie cookie = System.Web.HttpContext.Current.Request.Cookies.Get("COOKIE_NAME_FOR_USER");

ViewData["username"] = (cookie == null ? "" : cookie["COOKIE_USER_NAME"].ToString().Trim());

ViewData["userpass"] = (cookie == null ? "" : cookie["COOKIE_USER_PASS"].ToString().Trim());

if (cookie != null)

    ViewData["CHECKBOX"] = "checked=checked";

 

eturn View();
