一：新建WebApi项目【推荐搭配WebApi和MinimalApi使用】

1. 右键当前解决方案、添加、新建项目。
2. 点击ASP.NET Core Web API下一步。
3. 输入项目名称，后缀追加.WebApi。
4. 勾选使用控制器（取消选中以使用最小Api）。
5. 取消勾选不使用顶级语句。
6. 点击创建。
7. 右键管理NuGet包引入：
8. Microsoft.IdentityModel.Tokens
9. Newtonsoft.Json
10. System.IdentityModel.Tokens.Jwt

二：添加关键类

添加关键类JWTTokenOptions

namespace Study_ASP.NET_Core_MVC.AuthenticationCenter.Utility
{
    public class JWTTokenOptions
    {
        public string Audience { get; set; }
        public string SecurityKey { get;set; }
        public string Issuer { get; set; }
    }
}

添加关键类ICustomJWTService

namespace Study_ASP.NET_Core_MVC.AuthenticationCenter.Utility
{
    public interface ICustomJWTService
    {
        string GetToken(string UserName, string PassWord);
    }
}

添加关键类CustomHSJWTService

using Microsoft.Extensions.Options;
using Microsoft.IdentityModel.Tokens;
using System.IdentityModel.Tokens.Jwt;
using System.Security.Claims;
using System.Text;

namespace Study_ASP.NET_Core_MVC.AuthenticationCenter.Utility
{
    public class CustomHSJWTService : ICustomJWTService
    {
        /// 

        /// 注入构造函数
        /// 
        private readonly JWTTokenOptions _JWTTokenOptions;
        public CustomHSJWTService(IOptionsMonitor jwtTokenOptions)
        {
            this._JWTTokenOptions = jwtTokenOptions.CurrentValue;
        }
        /// 

        /// 用户登录成功之后
        /// 用来生成Token方法
        /// 
        /// 用户账号
        /// 用户密码
        /// 
        /// 
        public string GetToken(string UserName, string PassWord)
        {
            //有效载荷，避免敏感信息
            var claims = new[]
            {
                new Claim(ClaimTypes.Name,UserName),
                new Claim(ClaimTypes.Role,"Administrator"),
                new Claim("NickName",UserName),
                new Claim("Role","Admin"),
                new Claim("ABCD","ABCD"),
                new Claim("Student","酱油")
            };
            //获取加密KEY
            SymmetricSecurityKey key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_JWTTokenOptions.SecurityKey));
            //加密KEY
            SigningCredentials creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);
            //准备生成Token
            JwtSecurityToken token = new JwtSecurityToken(issuer: _JWTTokenOptions.Issuer, audience: _JWTTokenOptions.Audience, claims: claims, expires: DateTime.Now.AddMinutes(5), signingCredentials: creds);
            string returnToken = new JwtSecurityTokenHandler().WriteToken(token);
            return returnToken;
        }
    }
}

三：修改appsettings.json文件

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "AllowedHosts": "*",
  "JWTTokenOptions": {
    "Audience": "http://localhost:5200",
    "Issuer": "http://localhost:5200",
    "SecurityKey": "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDI2a2EJ7m872v0afyoSDJT2o1+SitIeJSWtLJU8/Wz2m7gStexajkeD+Lka6DSTy8gt9UwfgVQo6uKjVLG5Ex7PiGOODVqAEghBuS7JzIYU5RvI543nNDAPfnJsas96mSA7L/mD7RTE2drj6hf3oZjJpMPZUQI/B1Qjb5H3K3PNwIDAQAB"
  }
}

四：修改Program.cs文件

using Study_ASP.NET_Core_MVC.AuthenticationCenter.Utility;

//表示整个应用程序，调用CreateBuilder方法创建一个WebApplicationBuilder对象
var builder = WebApplication.CreateBuilder(args);

//向管道容器添加注册中间件
//添加注册Controller中间件
//添加注册Swagger中间件
builder.Services.AddControllers();
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
//添加注册JWT鉴权授权
builder.Services.Configure(builder.Configuration.GetSection("JWTTokenOptions"));
builder.Services.AddTransient();

//配置管道容器中间件，构造WebApplication实例
var app = builder.Build();

//配置HTTP请求管道判断开发者模式
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

//向管道添加用于将HTTP请求重定向到HTTPS的中间件
app.UseHttpsRedirection();
//向管道添加用于身份鉴权授权中间件
app.UseAuthorization();
//向管道添加用于Controller中间件
app.MapControllers();


//向管道添加启动应用程序中间件
app.Run();

五：添加控制器AuthenticationController

using Microsoft.AspNetCore.Mvc;
using Newtonsoft.Json;
using Study_ASP.NET_Core_MVC.AuthenticationCenter.Utility;

namespace Study_ASP.NET_Core_MVC.AuthenticationCenter.Controllers
{
    [Route("api/[controller]")]
    [ApiController]
    public class AuthenticationController : Controller
    {
        /// 

        /// 构造函数注入
        /// 
        private ICustomJWTService _iJWTService = null;
        public AuthenticationController(ICustomJWTService customJWTService)
        {
            _iJWTService = customJWTService;
        }
        [Route("Get")]
        [HttpGet]
        public IEnumerable Get()
        {
            return new List() { 1, 2, 3, 4, 6, 7 };
        }

        [Route("Login")]
        [HttpPost]
        public string Login(string UserName, string PassWord)
        {
            //判断用户账号和密码
            if ("VinCente".Equals(UserName) && "123456".Equals(PassWord))
            {
                //生成Token 
                string token = this._iJWTService.GetToken(UserName, PassWord);
                return JsonConvert.SerializeObject(new
                {
                    result = true,
                    token
                });

            }
            else
            {
                return JsonConvert.SerializeObject(new
                {
                    result = false,
                    token = ""
                });
            }
        }
    }
}
