AdminController中添加引用: Index添加[Authorize]权限要求: StartUp.cs中添加引用: StartUp.cs ConfigureServices中添加常量: 添加中间件: 此时,访问Admin页面,自动跳转至Account/Login?ReturnUrl=%2F ......
AdminController中添加引用:
using Microsoft.AspNetCore.Authorization;
Index添加[Authorize]权限要求:
[Authorize] public IActionResult Index() { return View(); }
StartUp.cs中添加引用:
using Microsoft.AspNetCore.Authentication; using Microsoft.AspNetCore.Authentication.Cookies;
StartUp.cs ConfigureServices中添加常量:
public void ConfigureServices(IServiceCollection services) { services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
.AddCookie(); services.AddMvc(); }
添加中间件:
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseAuthentication();
}
此时,访问Admin页面,自动跳转至Account/Login?ReturnUrl=%2FAdmin
添加AccountController.cs控制器,编写MakeLogin和Logout。此时访问Account/MakeLogin后,访问Admin能正常访问。
public class AccountController : Controller { public IActionResult MakeLogin() { var claims = new List<Claim> { new Claim(ClaimTypes.Name,"liumuu"), new Claim(ClaimTypes.Role,"admin") }; var claimIdentity = new ClaimsIdentity(claims, CookieAuthenticationDefaults.AuthenticationScheme); HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, new ClaimsPrincipal(claimIdentity)); return Ok(); } public IActionResult Logout() { HttpContext.SignOutAsync(); return Ok(); } }
可自定义默认选项:
public void ConfigureServices(IServiceCollection services) { services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme) .AddCookie(options => { options.LoginPath = "/Account/Login"; });
services.AddMvc(); }
新建ViewModel:
public class RegisterViewModel { public string Email { get; set; } public string Password { get; set; } public string ConfirmPassword { get; set; } }
public class LoginViewModel { [Required] [DataType(DataType.EmailAddress)] public string Email { get; set; } [Required] [DataType(DataType.Password)] public string Password { get; set; } }
@model RegisterViewModel @{ ViewData["Title"] = "Register"; } <h2>Register</h2> <div class="row"> <div class="col-md-4"> <form method="post"> <h4>Create Account</h4> <hr /> <div class="form-group"> <label asp-for="Email"></label> <input asp-for="Email" class="form-control" /> </div> <div class="form-group"> <label asp-for="Password"></label> <input asp-for="Password" type="password" class="form-control" /> </div> <div class="form-group"> <label asp-for="ConfirmPassword"></label> <input asp-for="ConfirmPassword" type="password" class="form-control" /> </div> <button type="submit" class="btn btn-default btn-sm">Regtister</button> </form> </div> </div>
@model LoginViewModel @{ ViewData["Title"] = "Login"; } <h2>Login</h2> <div class="row"> <div class="col-md-4"> <form method="post"> <h4>Use a Account to Login</h4> <hr /> <div class="form-group"> <label asp-for="Email"></label> <input asp-for="Email" class="form-control" /> </div> <div class="form-group"> <label asp-for="Password"></label> <input asp-for="Password" class="form-control" /> </div> <div class="form-group"> <button type="submit" class="btn btn-default btn-sm">Login</button> </div> </form> </div> </div>
创建Models:ApplicationUser.cs和ApplicationRole.cs:
public class ApplicationUser : IdentityUser<int> { }
public class ApplicationRole : IdentityRole<int> { }
数据连接:ApplicationDbContext.cs:
public class ApplicationDbContext : IdentityDbContext<ApplicationUser, ApplicationRole, int> { public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options) { } }
appsettings.json中添加数据链接:
{ "Logging": { "IncludeScopes": false, "LogLevel": { "Default": "Warning" } }, "GetConnectionString": { "Default": "Data Source = .; Database = database; User ID = sa; Password = 123" } }
StartUp.cs中添加数据引用、密码设置等:
public void ConfigureServices(IServiceCollection services) { services.AddDbContext<ApplicationDbContext>(options => { options.UseSqlServer(Configuration.GetConnectionString("Default")); }); services.AddIdentity<ApplicationUser, ApplicationRole>() .AddEntityFrameworkStores<ApplicationDbContext>() .AddDefaultTokenProviders(); services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme) .AddCookie(options => { options.LoginPath = "/Account/Login"; }); services.Configure<IdentityOptions>(options => { options.Password.RequireUppercase = false; options.Password.RequireNonAlphanumeric = false; options.Password.RequireLowercase = false; }); services.AddMvc(); }
编辑AccountController.cs:
private UserManager<ApplicationUser> _userManager; private SignInManager<ApplicationUser> _signInManager; public AccountController(UserManager<ApplicationUser> userManager, SignInManager<ApplicationUser> signInManager) { _userManager = userManager; _signInManager = signInManager; }
[HttpPost] public async Task<IActionResult> Register(RegisterViewModel registerViewModel) { var identityUser = new ApplicationUser { Email = registerViewModel.Email, UserName = registerViewModel.Email, NormalizedUserName = registerViewModel.Email }; var identityResult = await _userManager.CreateAsync(identityUser, registerViewModel.Password); if (identityResult.Succeeded) { return RedirectToAction("Index", "Home"); } return View(); }
