asp.net core cookie和jwt简单的登录认证

1. 首先在Startup.cs文件中配置Cookie认证和jwt认证

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Authentication.Cookies;
using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.IdentityModel.Tokens;

namespace JwtDemo
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews();
            //这里为jwt登录验证的的key,在配置文件中
            var securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["SecurityKey"]));
            services.AddSingleton(securityKey);
            //配置cookie认证和jwt认证
            services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
                .AddCookie(CookieAuthenticationDefaults.AuthenticationScheme, options =>
                {

                })
                .AddJwtBearer(JwtBearerDefaults.AuthenticationScheme, options =>
                {
                    options.TokenValidationParameters = new TokenValidationParameters
                    {
                        ValidateIssuer = true,
                        ValidateAudience = true,
                        ValidateLifetime = true,
                        ClockSkew = TimeSpan.FromSeconds(30),
                        ValidateIssuerSigningKey = true,
                        ValidAudience = "localhost",
                        ValidIssuer = "localhost",
                        IssuerSigningKey = securityKey
                    };
                });
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
            }
            app.UseStaticFiles();

            app.UseRouting();
			//使用认证中间件
            app.UseAuthentication();
            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }
}

2. 在appsettings.json中添加SecurityKey

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*",
  "SecurityKey": "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDI2a2EJ7m872v0afyoSDJT2o1+SitIeJSWtLJU8/Wz2m7gStexajkeD+Lka6DSTy8gt9UwfgVQo6uKjVLG5Ex7PiGOODVqAEghBuS7JzIYU5RvI543nNDAPfnJsas96mSA7L/mD7RTE2drj6hf3oZjJpMPZUQI/B1Qjb5H3K3PNwIDAQAB"
}

3. 测试代码:

using System;
using System.Collections.Generic;
using System.IdentityModel.Tokens.Jwt;
using System.Linq;
using System.Security.Claims;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Authentication;
using Microsoft.AspNetCore.Authentication.Cookies;
using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Mvc;
using Microsoft.IdentityModel.Tokens;

namespace JwtDemo.Controllers
{
    public class AccountController : Controller
    {
        public async Task<string> Login()
        {
            return await Task.FromResult("请先登录");
        }
		//使用cookie登录才能看到内容
        [Authorize]
        public IActionResult Content1()
        {
            return Content("只有登录的人才能看到");
        }
        
		//使用cookie认证才能看到内容
        [Authorize(AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme)]
        public IActionResult Content2()
        {
            return Content("只有登录的人才能看到");
        }

		// cookie和jwt认证
        [Authorize(AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme+","+CookieAuthenticationDefaults.AuthenticationScheme)]
        public IActionResult Content3()
        {
            return Content("只有登录的人才能看到");
        }
		
		// cookie登录
        public async Task<IActionResult> CookieLogin(string userName, string password)
        {
            var identity = new ClaimsIdentity(CookieAuthenticationDefaults.AuthenticationScheme);
            identity.AddClaim(new Claim("Name", userName));
            await this.HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, new ClaimsPrincipal(identity));
            return Content("登录"); 
        }

        /// <summary>
        /// token登录
        /// </summary>
        /// <param name="securityKey"></param>
        /// <param name="userName"></param>
        /// <returns></returns>
        public IActionResult JwtLogin([FromServices]SymmetricSecurityKey securityKey,string userName)
        {
            List<Claim> claims = new List<Claim>();
            claims.Add(new Claim("Name", userName));
            var creds = new SigningCredentials(securityKey, SecurityAlgorithms.HmacSha256);
            var token = new JwtSecurityToken(
                issuer: "localhost",
                audience: "localhost",
                claims:claims,
                expires:DateTime.Now.AddMinutes(30),
                signingCredentials:creds
                );
            var t = new JwtSecurityTokenHandler().WriteToken(token);
            var result = User.Identity.IsAuthenticated;
            return Content(t + "----" + result.ToString());
        }

    }
}
