最近刚做完一个项目，项目架构师使用mvc5+ef6+Bootstrap，用的是vs2015，数据库是sql server2014。下面小编把mvc5+ef6+Bootstrap项目心得之身份验证和权限管理模块的实现思路分享给大家，需要的朋友可以参考下
近和朋友完成了一个大单子架构是ef="/article/51254.html">mvc5+ef6+Bootstrap，用的是vs2015，数据库是sql server2014。朋友做的架构，项目完成后觉得很多值得我学习，在这里总结下一些心得。
创建项目一开始删掉App_Start目录下的IdentityConfig.cs和Startup.Auth.cs文件;清空Modle文件夹，Controller文件夹和相应的View; 删除目录下的ApplicationInsights.config文件和Startup.cs文件
修改web.config文件（添加<add key="owin:AutomaticAppStartup" value="false"/>不使用Startup.cs文件来启动项目）

<appSettings><add key="webpages:Version" value="3.0.0.0" /><add key="webpages:Enabled" value="false" /><add key="ClientValidationEnabled" value="true" /><add key="UnobtrusiveJavaScriptEnabled" value="true" /><add key="owin:AutomaticAppStartup" value="false"/> <!--去掉创建项目初的Startup.cs文件的设置--></appSettings> |
（不用他们是因为自带的这些内容太冗余）
去掉冗余内容正式开始,首先介绍数据库这一块，数据库我们是配置的可以手动生成和修改的
1.在项目目录想创建Migrations文件夹，里面添加Configuration.cs文件

internal sealed class Configuration : DbMigrationsConfiguration<AccountContext>{public Configuration(){AutomaticMigrationsEnabled = true;ContextKey = "UserProject.DAL.AccountContext";}protected override void Seed(AccountContext context){//base.Seed(context);}} |
在Modle文件夹下添加AccountContext.cs文件

public class AccountContext:DbContext{public AccountContext():base("AccountContext") {}public DbSet<User> Users { get; set; }protected override void OnModelCreating(DbModelBuilder modelBuilder){modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();}}<connectionStrings><add name="AccountContext" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\UserProject.mdf;Initial Catalog=UserProject;Integrated Security=True" providerName="System.Data.SqlClient" /></connectionStrings> |
然后 使用vs2015里面的工具-NuGet包管理器-程序包管理控制平台
输入add-migration Initial 按回车，在输入update-database按回车。在App_Data文件夹下就会看到AccountContext数据库了。
2.在Modle文件夹下添加User.css文件

public class User{public int ID { get; set; }public string UserName { get; set; }public string Password { get; set; }public Role Role { get; set; }}public enum Role//角色枚举{ 管理员 = 0, 员工 = 1, 经理 = 2, 总经理 = 3, 董事长 = 4 } |
在ViewModle文件夹中添加Account.cs文件

public class Account{[Required]public string Name { get; set; }[Required]public string Password { get; set; }public string RePassword { get; set; }} |
这里推荐创建BaseController之后的Controller就继承它来使用

public class BaseController : Controller{public string UserName => User.Identity.Name;public AccountContext db = new AccountContext();private User _userInfo = null;public User CurrentUserInfo{get{if (_userInfo == null){var user = db.Users.SingleOrDefault(u => u.UserName == UserName);//此处为了不每次访问用户表可以做一个静态类，里面存放用户表信息._userInfo = user == null ? null : new User(){ID = user.ID,UserName = user.UserName,Role = user.Role};}return _userInfo;}} //验证角色：获取Action的CustomAttributes，过滤角色protected override void OnActionExecuting(ActionExecutingContext filterContext){base.OnActionExecuting(filterContext);var authRoleAtt = filterContext.ActionDescriptor.GetCustomAttributes(false).SingleOrDefault(att => att is AuthorizeRoleAttribute) as AuthorizeRoleAttribute;if (authRoleAtt == null && CurrentUserInfo != null)return;if (!authRoleAtt.Roles.Contains(CurrentUserInfo.Role)){filterContext.Result = View("NoPermission", "_Layout", "您没有权限访问此功能!");}}//这里是记log用protected override void OnActionExecuted(ActionExecutedContext filterContext){base.OnActionExecuted(filterContext);var msg = $"用户: {CurrentUserInfo?.UserName}, 链接: {Request.Url}";if (Request.HttpMethod == "POST")msg += $", 数据: {HttpUtility.UrlDecode(Request.Form.ToString())}";//Log.Debug(msg);}} |
AdminController继承BaseController

[AllowAnonymous]public ActionResult Login(){return View();}[HttpPost, AllowAnonymous]public ActionResult Login(Account model){if (ModelState.IsValid){var user = db.Users.SingleOrDefault(t => t.UserName == model.Name && t.Password == model.Password);if (user != null){FormsAuthentication.SetAuthCookie(model.Name, false);//将用户名放入Cookie中}else{ModelState.AddModelError("Name", "用户名不存在!");}}return View(model);}public ActionResult LogOff(){FormsAuthentication.SignOut();return RedirectToAction("Login");} |
按照以上方式 访问Details这个Action的时候必须是管理员角色。
以上所述是小编给大家介绍的基于mvc5+ef6+Bootstrap框架实现身份验证和权限管理，希望对大家有所帮助，如果大家有任何疑问请给我留言，小编会及时回复大家的。在此也非常感谢大家对米米素材网网站的支持！
