.net core jwt 实现简易授权

jwt授权拓展类AddAuth：

using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.IdentityModel.Tokens;
using Siia.MobileApi.Extensions.Jwt;
using System;
using System.Text;

namespace Siia.MobileApi.Extensions
{
    public static class AuthenticationExt
    {
        public static void AddAuth(this IServiceCollection services, IConfiguration configuration)
        {
            if (services == null) throw new ArgumentNullException(nameof(services));

            JwtSettings jwtSettings = new JwtSettings();
            services.Configure<JwtSettings>(configuration.GetSection("JwtSettings"));
            configuration.GetSection("JwtSettings").Bind(jwtSettings);

            services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
                .AddJwtBearer(o =>
                {
                    o.TokenValidationParameters = new TokenValidationParameters()
                    {
                        ValidateIssuerSigningKey = true,
                        ValidateIssuer = true,//是否验证Issuer
                        ValidateAudience = true,//是否验证Audience
                        ValidateLifetime = true,//是否验证失效时间
                        ValidIssuer = jwtSettings.Issuer,
                        ValidAudience = jwtSettings.Audience,
                        //用于签名验证
                        IssuerSigningKey = new SymmetricSecurityKey(Encoding.ASCII.GetBytes(jwtSettings.SecretKey)),
                        //注意这是缓冲过期时间，总的有效时间等于这个时间加上jwt的过期时间，如果不配置，默认是5分钟
                        //ClockSkew = TimeSpan.FromSeconds(4)
                    };
                });
            services.AddTransient<IPassport, Passport>(PassportFactory);
        }
        private static Passport PassportFactory(IServiceProvider provider)
        {
            var httpAccessor = provider.GetService<IHttpContextAccessor>();
            if (httpAccessor == null)
            {
                return null;
            }
            return new Passport(httpAccessor.HttpContext?.User);
        }
    }

ConfigureServices中注入AddAuth： services.AddAuth(Configuration);

 public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllers();

            services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
            services.AddSwagger();
            services.AddAuth(Configuration);
            services.AddScoped<IJwt, Jwt>(); // Jwt注入

            //json 序列化问题
            services.AddControllers().AddNewtonsoftJson(options =>
            {
                options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
                options.SerializerSettings.DateFormatString = "yyyy-MM-dd HH:mm:ss"; //指定时间的序列化格式
                options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore; //忽略循环引用
            });

            //解决中文被编码
            services.AddSingleton(HtmlEncoder.Create(UnicodeRanges.All));

            services.AddHttpClient("Siia.MobileApi");
            //防止回收
            services.AddQuartzHostedService()
                .AddQuartzJob<WeatherMonitoring>()
               .AddQuartzJob<HealthCheckJob>();

            //services.AddSingleton<MessageQueueFunc>();
        }

app.UseAuthorization();

            var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);
