在Startup类中添加授权和验证的注入对象和中间件
1.在ConfigureServices方法注入对象
//验证注入services.AddAuthentication ( opts=>opts.DefaultScheme= Microsoft.AspNetCore.Authentication.Cookies.CookieAuthenticationDefaults.AuthenticationScheme ).AddCookie( Microsoft.AspNetCore.Authentication.Cookies.CookieAuthenticationDefaults.AuthenticationScheme , opt => { opt.LoginPath = new Microsoft.AspNetCore.Http.PathString("/login"); opt.AccessDeniedPath= new Microsoft.AspNetCore.Http.PathString("/home/error"); opt.LogoutPath= new Microsoft.AspNetCore.Http.PathString("/login"); opt.Cookie.Path = "/"; } );
2.在Configure方法中添加中间件
//开启验证中间件app.UseAuthentication();
在特效下去授权controller和action
[Authorize(Roles ="admin")]//允许那些角色访问[AllowAnonymous]//允许所有人访问
登录方法
[HttpGet("login")] [AllowAnonymous]//允许所有人访问 public IActionResult Login( string returnUrl) { //没有通过验证 if ( ! HttpContext.User.Identity.IsAuthenticated) { ViewBag.returnUrl = returnUrl; } return View(); }
登录实现功能方法
[HttpPost("login")][AllowAnonymous]//允许所有人访问public IActionResult Login(string NET_User, string PassWord ,string returnUrl) { if (NET_User == "123" && PassWord == "123") { var claims = new System.Security.Claims.Claim[] { new System.Security.Claims.Claim(System.Security.Claims.ClaimTypes.Role,"admin"), //User.Identity.Name new System.Security.Claims.Claim(System.Security.Claims.ClaimTypes.Name,"NAME"), }; HttpContext.SignInAsync( Microsoft.AspNetCore.Authentication.Cookies.CookieAuthenticationDefaults.AuthenticationScheme, new System.Security.Claims.ClaimsPrincipal(new System.Security.Claims.ClaimsIdentity(claims)) ); return new RedirectResult(string.IsNullOrEmpty(returnUrl) ? "/home/index":returnUrl); } else { ViewBag.error = "用户名或密码错误"; return View(); }}
