近和朋友完成了一个大单子架构是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
[Authorize] public ActionResult Index() { return View(db.Users.ToList()); } [Authorize, AuthorizeRole(Role.管理员)] public ActionResult Details(int? id) { if (id == null) { return new HttpStatusCodeResult(HttpStatusCode.BadRequest); } User user = db.Users.Find(id); if (user == null) { return HttpNotFound(); } return View(user); }
登录页面:
@model UserProject.ViewModels.Account @{ ViewBag.Title = "Login"; } @using (Html.BeginForm("Login", "Admin",FormMethod.Post, new { @class = "form-horizontal", role = "form" })) { @Html.AntiForgeryToken() <hr /> @Html.ValidationSummary(true, "", new { @class = "text-danger" }) <div class="form-group"> @Html.LabelFor(m => m.Name, new { @class = "col-md-2 control-label" }) <div class="col-md-10"> @Html.TextBoxFor(m => m.Name, new { @class = "form-control" }) @Html.ValidationMessageFor(m => m.Name, "", new { @class = "text-danger" }) </div> </div> <div class="form-group"> @Html.LabelFor(m => m.Password, new { @class = "col-md-2 control-label" }) <div class="col-md-10"> @Html.PasswordFor(m => m.Password, new { @class = "form-control" }) @Html.ValidationMessageFor(m => m.Password, "", new { @class = "text-danger" }) </div> </div> <div class="form-group"> <div class="col-md-offset-2 col-md-10"> <input type="submit" value="登录" class="btn btn-primary" /> </div> </div> }
登录的Action:
[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 return RedirectToAction("Index"); } 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。
