Kiv*_*oon 4 asp.net-mvc login roles asp.net-mvc-4
我是MVC的新手,我在堆栈上看过类似的帖子,但他们似乎没有帮我解决问题.我有两个角色Admin和User.当一个人登录时,我希望根据该人是否具有管理员权限或用户权限来更改布局.
我的管理员布局是_Layout.cshtml
我的用户布局是_LayoutUser.cshtml
我的登录控制器中是否有可以根据用户角色更改布局的内容？用户的角色在Login表中指定.
id LoginStudentNumber LoginPassword Role
1 123456 123456 Admin
2 234567 234567 Admin
3 345678 345678 User
4 456789 456789 User
登录控制器:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using RMS.DAL;
using RMS.Models;
namespace RMS.Controllers
{
public class LoginController : Controller
{
RMSContext db = new RMSContext();
[AllowAnonymous]
public ActionResult Login(string returnUrl)
{
ViewBag.ReturnUrl = returnUrl;
return View();
}
//
// POST: /Account/Login
[HttpPost]
[AllowAnonymous]
public ActionResult Login(Login model, int? LoginStudentNumber, string LoginPassword)
{
//RMS.Models.Login user = db.Logins.Find(LoginID);
RMS.Models.Login user = db.Logins.FirstOrDefault(l => l.LoginStudentNumber == model.LoginStudentNumber);
if (user == null)
{
ViewBag.InvalidID = "Invalid User Id";
return View(model);
}
if ((user.LoginPassword.Equals(LoginPassword)) && (user.Role.Equals("Admin")))
{
return RedirectToAction("Index", "Home");
}
if ((user.LoginPassword.Equals(LoginPassword)) && (user.Role.Equals("User")))
{
return RedirectToAction("IndexUser", "Home");
}
ViewBag.InvalidPassword = "Invalid Password";
return View(model);
}
}
}

您只需要修改该/Views/_ViewStart.cshtml文件.
@{
if (this.User.IsInRole("Admin") || !this.User.Identity.IsAuthenticated) {
Layout = "~/Views/Shared/_Layout.cshtml";
} else {
Layout = "~/Views/Shared/_LayoutUser.cshtml";
}
}
您没有提到如果没有用户登录会发生什么,所以我添加了检查并将它们发送到
_Layout.cshtml视图.您应该根据应用程序的需要更改逻辑.
