问题描述
我是MVC的新手，我浏览了堆栈中的类似文章，但它们似乎并没有解决我的问题.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 Admin 特权或 User 特权来更改布局.
I am new to MVC, I looked through similar posts on stack, but they did'nt seem to help my problem. I have two roles Admin and User. When a person logs in, I want the layout to change based on whether the person had Admin privileges or User Privileges.
我的 Admin 布局为_Layout.cshtml
我的 User 布局是_LayoutUser.cshtml
我的登录控制器中是否可以放置某些内容，这些内容将根据用户的角色来更改布局?用户的角色在登录"表中指定.
Is there something in my Login Controller that I can put which will change the layout based on the role of the User? The role of the user is specified in the Login table.
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);
}
}
}

推荐答案
您只需要修改/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该怎么办，所以我添加了支票并将其发送到
_Layout.cshtml视图.您应该根据应用程序的需要更改逻辑.
You didn't mention what should happen if no user is logged in, so I added the check and just sent them to the
_Layout.cshtmlview. You should change the logic as needed for your application.
