.net core權(quán)限認(rèn)證

在Startup類中添加授權(quán)和驗(yàn)證的注入對(duì)象和中間件

1.在ConfigureServices方法注入對(duì)象

//驗(yàn)證注入
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方法中添加中間件

//開啟驗(yàn)證中間件
app.UseAuthentication();

在特效下去授權(quán)controller和action

[Authorize(Roles ="admin")]//允許那些角色訪問
[AllowAnonymous]//允許所有人訪問

登錄方法

        [HttpGet("login")]
        [AllowAnonymous]//允許所有人訪問
        public IActionResult Login( string returnUrl) {
            //沒有通過驗(yàn)證
            if ( ! HttpContext.User.Identity.IsAuthenticated) {
                ViewBag.returnUrl = returnUrl;
            }
            return View();
        }

登錄實(shí)現(xiàn)功能方法

[HttpPost("login")]
[AllowAnonymous]//允許所有人訪問
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 = "用戶名或密碼錯(cuò)誤";
		return View();
	}

}
