首先在Startup的ConfigureServices方法添加一段权限代码
services.AddAuthentication(x=> {
x.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
x.DefaultChallengeScheme = CookieAuthenticationDefaults.AuthenticationScheme;
x.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
}).AddCookie(CookieAuthenticationDefaults.AuthenticationScheme, x =>
{
//登录地址
x.LoginPath = "/Home/Login";
//sid
x.Cookie.Name = "mycookie";
x.Cookie.Path = "/";
x.Cookie.HttpOnly = true;
x.Cookie.Expiration = new TimeSpan(0, 0, 30);
x.ExpireTimeSpan = new TimeSpan(0, 0, 30);
});
这里整理下目录。
有个HomeController，首页的Index页面添加[Authorize]，需要权限进入
有个Login的action，登录页
添加登录方法SignIn
public async Task<IActionResult> SignIn(LoginViewModel model)
{
if (ModelState.IsValid)
{
var claims = new List<Claim>();
claims.Add(new Claim(ClaimTypes.Name, model.UserName));
var identity = new ClaimsIdentity(claims, "login");
var principal = new ClaimsPrincipal(identity);
await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal);
if (principal.Identity.IsAuthenticated)
return RedirectToAction("Index");
}
return View();
}
添加登录页面
@{
ViewData["Title"] = "Login";
}
<h2>Login</h2>
<form method="post" action="/home/SignIn">
用户名<input type="text" name="username" />
密码<input type="password" name="password" />
<button type="submit" class="btn">登录</button>
</form>
因为在Startup里面配置了当没权限时进入登录页面
x.LoginPath = "/Home/Login";
此时运行程序，会跳转到登录页面
输入用户名密码登陆，登录验证成功后就可以跳转到Index了。
再添加个退出
public async Task<IActionResult> SignOut() { if (HttpContext.User.Identity.IsAuthenticated) await HttpContext.SignOutAsync(CookieAuthenticationDefaults.AuthenticationScheme); return RedirectToAction("Login"); }
在页面上可以通过这段代码判断是否登录
Context.User.Identity.IsAuthenticated
