前台用href='/Home/Logout'请求,后台使用Redirect()、RedirectToAction()进行控制跳转 。
退出
public class HomeController : Controller
{
public ActionResult Logout()
{
Session.Abandon();
return Redirect("/Login/Index");
//return RedirectToAction("Index", "Login");
}
}
如果前台使用了ajax发起请求,那就只能在success:function(data){ }中进行页面跳转了,后台写的return View()、return Redirect()、return RedirectToAction()最多只能执行Action,不会跳转页面。
function logout() {
alert("logout()");
$.ajax({
type: "post",
url: "/Home/Logout",
success: function (data) {
//window.location.href = '/Login/Index';
window.location.href = '@Url.Action("Index", "Login")';
},
error: function (err) { }
});
}
public class HomeController : Controller
{
public ActionResult Logout()
{
Session.Abandon();
return Redirect("/Login/Index");
//return RedirectToAction("Index", "Login");
//return View("/Login/Index");
}
}
Statrup.cs中的路由配置
app.UseMvc(routes =>
{
routes.MapAreaRoute(
name: "areasSys",
areaName: "Sys",
template: "Sys/{controller=Home}/{action=Index}/{id?}"
);
routes.MapAreaRoute(
name: "areasPersonalAccount",
areaName: "PersonalAccount",
template: "PersonalAccount/{controller=Home}/{action=Index}/{id?}"
);
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});

//[跨Area重定向方法1]
return Redirect("/Sys/Sys_Dictionary/Index");
}
}
Sys_Dictionary控制器的Index页及后台方法(Sys区域重定向到PersonalAccount区域)
public class Sys_DictionaryController : Controller
{
public IActionResult Index()
{
return View();
}
public IActionResult SkipToAreaPersonalAccount()
{
//[跨Area重定向方法1]
return Redirect("/PersonalAccount/PersonalAccount_Apply/Index");
}
}
