ASP.NET Core Identity Server 3自定义修改Token过期刷新时间

1、自定义DefaultRefreshTokenService类刷新Token

Identity Server 3的默认实现类，可以参考根据自己的需求，自定义实现：DefaultRefreshTokenService源代码

下面的MyDefaultRefreshTokenService类重写CreateRefreshTokenAsync方法，来实现针对不同用户设置不同的刷新时间(过期时间)，另外，MyDefaultRefreshTokenService类项目中还要引用IdentityModel，直接Nuget中安装IdentityModel即可。

相关文档：VS(Visual Studio)中Nuget的使用

using IdentityModel;using IdentityServer3.Core.Logging;using IdentityServer3.Core.Models;using IdentityServer3.Core.Services;using IdentityServer3.Core.Services.Default;using System;using System.Collections.Generic;using System.Linq;using System.Security.Claims;using System.Threading.Tasks;namespace Host.AspNetCore{    public class MyDefaultRefreshTokenService : DefaultRefreshTokenService    {        private readonly static ILog Logger = LogProvider.GetCurrentClassLogger();        public MyDefaultRefreshTokenService(IRefreshTokenStore store, IEventService events) : base(store, events)        {        }        public override async Task CreateRefreshTokenAsync(ClaimsPrincipal subject, Token accessToken, Client client)        {           // return base.CreateRefreshTokenAsync(subject, accessToken, client);            Logger.Debug("Creating refresh token");            int lifetime;            //这里可以根据需求，不同的用户设置不同的token刷新时间            if (client.RefreshTokenExpiration == TokenExpiration.Absolute)            {                Logger.Debug("Setting an absolute lifetime: " + client.AbsoluteRefreshTokenLifetime);                lifetime = client.AbsoluteRefreshTokenLifetime;            }            else            {                Logger.Debug("Setting a sliding lifetime: " + client.SlidingRefreshTokenLifetime);                lifetime = client.SlidingRefreshTokenLifetime;            }            var handle = CryptoRandom.CreateUniqueId();            var refreshToken = new RefreshToken            {                CreationTime = DateTimeOffset.UtcNow,                LifeTime = lifetime,                AccessToken = accessToken,                Subject = subject            };            await _store.StoreAsync(handle, refreshToken);            await RaiseRefreshTokenIssuedEventAsync(handle, refreshToken);            return handle;        }    }}

2、Startup.cs中配置RefreshTokenService

将RefreshTokenService配置为MyDefaultRefreshTokenService

public void Configure(IApplicationBuilder app, IHostingEnvironment host)
        {
            Log.Logger = new LoggerConfiguration()
               .MinimumLevel.Debug()
               .WriteTo.File(@"c:\logs\idsvrlog.txt")
               .CreateLogger();
            app.Map("/core", coreApp =>
            {
                var factory = new IdentityServerServiceFactory()
                    .UseInMemoryClients(Clients.Get())
                    .UseInMemoryScopes(Scopes.Get())
                    .UseInMemoryUsers(Users.Get());
                var refreshTokenService = new MyDefaultRefreshTokenService(new InMemoryRefreshTokenStore(), new DefaultEventService());
                factory.RefreshTokenService = new Registration(resolver => refreshTokenService);
                var options = new IdentityServerOptions
                {
                    SiteName = "IdentityServer3 - AspNet Core",
                    SigningCertificate = Certificate.Get(host.ContentRootPath),
                    Factory = factory,
                };
                coreApp.UseIdentityServer(options);
            });
        }
