ASP.Net MVC Session和Cookies的简单使用

目标：用Session和Cookies实现登陆信息保存和展现

Cookies实现:

Controller:

   //把登陆用户名存到cookies中
  HttpCookie cook = new HttpCookie("cookusername", UserName.ToString());
  Response.Cookies.Add(cook);

View:

<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button"
                           aria-expanded="false">
                            <i class="fa fa-user-o fa-fw"></i>
                            @if (Request.Cookies["cookusername"]!= null)
                            {
                                @Request.Cookies["cookusername"].Value;
                            }
                            <span class="caret"></span>
                        </a>

Session实现:

controller:

  //登陆成功把用户名存入session
 Session["username"] = UserName.ToString();

View:

 <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button"
                            aria-expanded="false">
                             <i class="fa fa-user-o fa-fw"></i>
                             @if (Session["username"]!= null)
                             {
                                 @Session["username"].ToString();
                             }
                             <span class="caret"></span>
                         </a>

在web.config设置Session过期时间

<system.web>
<sessionState mode="InProc" timeout="30"></sessionState>  <!--session过期时间设置-->
</system.web>
