过滤器:
public class MyActionFilter : ActionFilterAttribute//继承ActionFilterAttribute类
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
//用session验证是否登陆过
if(filterContext.HttpContext.Session["visitor_name"] == null)
{
//未登录则跳转到登录页面,并拖过url?传递状态码?Login_state=false用于前端验证并友好提示
filterContext.HttpContext.Response.Redirect("/Login_/Index?Login_state=false",true);
}
}
}
Login_Controller.cs:
public ActionResult Login(string name, string pwd)//传进来的字符串实际没用上
{
var get_name = Request["name"];
var get_pwd = Request["pwd"];
JJQPractice visitor = JJQPractice.SingleOrDefault(new { name = get_name });//得到对应输入的账号的集
if (visitor != null)//验证输入的账号是否存在
{
if (visitor.pwd == get_pwd)//验证密码是否正确
{
Session["visitor_name"] = get_name;//在session中写入name用于判断登录状态
return RedirectToAction("Index", "Select_");//密码正确后跳转到查询视图
}
else
{
Response.Write("登录失败!密码错误.");
return View("Index");
}
}
else
{
Response.Write("登录失败,用户名不存在.");
return View("Index");
}
}
