.NET Core中JWT+OAuth2.0实现SSO，附完整源码（.NET6）
一、简介
单点登录(SingleSignOn，SSO)
指的是在多个应用系统中，只需登录一次，就可以访问其他相互信任的应用系统。
JWT
json Web Token，这里不详细描述，简单说是一种认证机制。
OAuth2.0
OAuth2.0是一个认证流程，一共有四种方式，这里用的是最常用的授权码方式，流程为：
1、系统A向认证中心先获取一个授权码code。
2、系统A通过授权码code获取 token，refresh_token，expiry_time，scope。
token：系统A向认证方获取资源请求时带上的token。
refresh_token：token的有效期比较短，用来刷新token用。
expiry_time：token过期时间。
这里的SSO都是公司自己的系统，都是获取用户信息，所以这个为空，第三方需要接入我们的登录时才需要scope来做资源权限判断。
二、实现目标
1、一处登录，全部登录
流程图为：
1、浏览器访问A系统，发现A系统未登录，跳转到统一登录中心（SSO），带上A系统的回调地址，
地址为：token，实际项目应该存到数据库。
{ "Logging": { "LogLevel": { "Default": "Information", "Microsoft.AspNetCore": "Warning" } }, "AllowedHosts": "*", "AppSetting": { "appHSSettings": [ { "domain": " "clientId": "web1", "clientSecret": "Nu4Ohg8mfpPnNxnXu53W4g0yWLqF0mX2" }, { "domain": " "clientId": "web2", "clientSecret": "pQeP5X9wejpFfQGgSjyWB8iFdLDGHEV8" } ] } }
domain：接入系统的域名，可以用来校验请求来源是否合法。
clientId：接入系统标识，请求token时传进来识别是哪个系统。
clientSecret：接入系统密钥，用来生成对称加密的JWT。
建一个IJWTService定义JWT生成需要的方法

新建类JWTHSService实现对称加密
/// /// JWT对称可逆加密 /// public class JWTHSService : JWTBaseService { public JWTHSService(IOptions options, Cachelper cachelper):base(options,cachelper) { } /// /// 生成对称加密签名凭证 /// /// /// protected override SigningCredentials GetCreds(string clientId) { var appHSSettings=getAppInfoByAppKey(clientId); var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(appHSSettings.clientSecret)); var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256); return creds; } /// /// 根据appKey获取应用信息 /// /// /// private AppHSSetting getAppInfoByAppKey(string clientId) { AppHSSetting appHSSetting = _appSettingOptions.Value.appHSSettings.Where(s => s.clientId == clientId).FirstOrDefault(); return appHSSetting; } }
新建JWTRSService类实现非对称加密，和上面的对称加密，只需要一个就可以里，这里把两种都写出来了
/// /// JWT非对称加密 /// public class JWTRSService : JWTBaseService { public JWTRSService(IOptions options, Cachelper cachelper):base(options, cachelper) { } /// /// 生成非对称加密签名凭证 /// /// /// protected override SigningCredentials GetCreds(string clientId) { var appRSSetting = getAppInfoByAppKey(clientId); var rsa = RSA.Create(); byte[] privateKey = Convert.FromBase64String(appRSSetting.privateKey);//这里只需要私钥，不要begin,不要end rsa.ImportPkcs8PrivateKey(privateKey, out _); var key = new RsaSecurityKey(rsa); var creds = new SigningCredentials(key, SecurityAlgorithms.RsaSha256); return creds; } /// /// 根据appKey获取应用信息 /// /// /// private AppRSSetting getAppInfoByAppKey(string clientId) { AppRSSetting appRSSetting = _appSettingOptions.Value.appRSSettings.Where(s => s.clientId == clientId).FirstOrDefault(); return appRSSetting; } }
什么时候用JWT的对称加密，什么时候用JWT的非对称加密呢？
对称加密：双方保存同一个密钥，签名速度快，但因为双方密钥一样，所以安全性比非对称加密低一些。
非对称加密：认证方保存私钥，系统方保存公钥，签名速度比对称加密慢，但公钥私钥互相不能推导，所以安全性高。
所以注重性能的用对称加密，注重安全的用非对称加密，一般是公司的系统用对称加密，第三方接入的话用非对称加密。
web1项目：
appsettings.json存着web1的信息
{ "Logging": { "LogLevel": { "Default": "Information", "Microsoft.AspNetCore": "Warning" } }, "AllowedHosts": "*", "SSOSetting": { "issuer": "SSOCenter", "audience": "web1", "clientId": "web1", "clientSecret": "Nu4Ohg8mfpPnNxnXu53W4g0yWLqF0mX2" }}
Program.cs文件加入认证代码，加入builder.Services.AddAuthentication(。。。和加入app.UseAuthentication()，完整代码如下：
using Microsoft.AspNetCore.Authentication.JwtBearer;using Microsoft.IdentityModel.Tokens;using RSAExtensions;using SSO.Demo.Web1.Models;using SSO.Demo.Web1.Utils;using System.Security.Cryptography;using System.Text;var builder = WebApplication.CreateBuilder(args);// Add services to the container.builder.Services.AddControllersWithViews();builder.Services.AddHttpClient();builder.Services.AddSingleton();builder.Services.Configure(builder.Configuration.GetSection("AppOptions"));builder.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme) .AddJwtBearer(options => { options.TokenValidationParameters = new TokenValidationParameters { //Audience,Issuer,clientSecret的值要和sso的一致 //JWT有一些默认的属性，就是给鉴权时就可以筛选了 ValidateIssuer = true,//是否验证Issuer ValidateAudience = true,//是否验证Audience ValidateLifetime = true,//是否验证失效时间 ValidateIssuerSigningKey = true,//是否验证client secret ValidIssuer = builder.Configuration["SSOSetting:issuer"],// ValidAudience = builder.Configuration["SSOSetting:audience"],//Issuer，这两项和前面签发jwt的设置一致 IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(builder.Configuration["SSOSetting:clientSecret"]))//client secret }; });#region 非对称加密-鉴权//var rsa = RSA.Create();//byte[] publickey = Convert.FromBase64String(AppSetting.PublicKey); //公钥，去掉begin... end ...////rsa.ImportPkcs8PublicKey 是一个扩展方法，来源于RSAExtensions包//rsa.ImportPkcs8PublicKey(publickey);//var key = new RsaSecurityKey(rsa);//var signingCredentials = new SigningCredentials(key, SecurityAlgorithms.RsaPKCS1);//builder.Services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)// .AddJwtBearer(options =>// {// options.TokenValidationParameters = new TokenValidationParameters// {// //Audience,Issuer,clientSecret的值要和sso的一致// //JWT有一些默认的属性，就是给鉴权时就可以筛选了// ValidateIssuer = true,//是否验证Issuer// ValidateAudience = true,//是否验证Audience// ValidateLifetime = true,//是否验证失效时间// ValidateIssuerSigningKey = true,//是否验证client secret// ValidIssuer = builder.Configuration["SSOSetting:issuer"],//// ValidAudience = builder.Configuration["SSOSetting:audience"],//Issuer，这两项和前面签发jwt的设置一致// IssuerSigningKey = signingCredentials.Key// };// });#endregionvar app = builder.Build();ServiceLocator.Instance = app.Services; //用于手动获取DI对象// Configure the HTTP request pipeline.if (!app.Environment.IsDevelopment()){ app.UseExceptionHandler("/Home/Error"); // The default HSTS value is 30 days. You may want to change this for production scenarios, see app.UseHsts();}app.UseHttpsRedirection();app.UseStaticFiles();app.UseRouting();app.UseAuthentication();//这个加在UseAuthorization 前app.UseAuthorization();app.MapControllerRoute( name: "default", pattern: "{controller=Home}/{action=Index}/{id?}");app.Run();
然后加接口根据授权code获取token，增加AccountController
/// /// 用户信息 /// public class AccountController : Controller { private IHttpClientFactory _ private readonly Cachelper _cachelper; public AccountController(IHttpClientFactory Cachelper cachelper) { _= _cachelper = cachelper; } /// /// 获取用户信息，接口需要进行权限校验 /// /// [MyAuthorize] [HttpPost] public ResponseModel GetUserInfo() { ResponseModel user = new ResponseModel(); return user; } /// /// 登录成功回调 /// /// public ActionResult LoginRedirect() { return View(); } //根据authCode获取token [HttpPost] public async Task> GetAccessCode([FromBody] GetAccessCodeRequest request) { ResponseModel result = new ResponseModel(); //请求SSO获取 token var client = _ var param = new { authCode = request.authCode }; string jsonData = System.Text.Json.JsonSerializer.Serialize(param); StringContent paramContent = new StringContent(jsonData); //请求sso获取token var response = await client.PostAsync("new StringContent(jsonData, Encoding.UTF8, "application/json")); string resultStr = await response.Content.ReadAsStringAsync(); result = System.Text.Json.JsonSerializer.Deserialize>(resultStr); if (result.code == 0) //成功 { //成功,缓存token到局部会话 string token = result.data.token; string key = $"SessionCode:{request.sessionCode}"; string tokenKey = $"token:{token}"; _cachelper.StringSet(key, token, TimeSpan.FromSeconds(result.data.expires)); _cachelper.StringSet(tokenKey, true, TimeSpan.FromSeconds(result.data.expires)); Console.WriteLine($"获取token成功，局部会话code:{request.sessionCode},{Environment.NewLine}token:{token}"); } return result; } /// /// 退出登录 /// /// /// [HttpPost] public ResponseModel LogOut([FromBody] LogOutRequest request) { string key = $"SessionCode:{request.SessionCode}"; //根据会话取出token string token = _cachelper.StringGet(key); if (!string.IsNullOrEmpty(token)) { //清除token string tokenKey = $"token:{token}"; _cachelper.DeleteKey(tokenKey); } Console.WriteLine($"会话Code:{request.SessionCode}退出登录"); return new ResponseModel().SetSuccess(); } }
还有得到的token还没过期，如果我退出登录了，怎么判断这个会话token失效了呢？
这里需要拦截认证过滤器，判断token在缓存中被删除，则认证不通过，增加文件MyAuthorize
/// /// 拦截认证过滤器 /// public class MyAuthorize : Attribute, IAuthorizationFilter { private static Cachelper _cachelper = ServiceLocator.Instance.GetService(); public void OnAuthorization(AuthorizationFilterContext context) { string id = context.HttpContext.User.FindFirst("id")?.Value; if(string.IsNullOrEmpty(id)) { //token检验失败 context.Result = new StatusCodeResult(401); //返回鉴权失败 return; } Console.WriteLine("我是Authorization过滤器"); //请求的地址 var url = context.HttpContext.Request.Path.Value; //获取打印头部信息 var heads = context.HttpContext.Request.Headers; //取到token "Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJodHRwOi8vc2NoZW1hcy54bWxzb2FwLm9yZy93cy8yMDA1LzA1L2lkZW50aXR5L2NsYWltcy9uYW1lIjoi5byg5LiJIiwiQWNjb3VudCI6ImFkbWluIiwiSWQiOiIxMDEiLCJNb2JpbGUiOiIxMzgwMDEzODAwMCIsImh0dHA6Ly9zY2hlbWFzLm1pY3Jvc29mdC5jb20vd3MvMjAwOC8wNi9pZGVudGl0eS9jbGFpbXMvcm9sZSI6IlN1cGVyQWRtaW4iLCJleHAiOjE2NTMwNjA0MDIsImlzcyI6IlNTT0NlbnRlciIsImF1ZCI6IndlYjIifQ.aAi5a0zr_nLQQaSxSBqEhHZQ6ALFD_rWn2tnLt38DeA" string token = heads["Authorization"]; token = token.Replace("Bearer", "").TrimStart();//去掉 "Bearer "才是真正的token if (string.IsNullOrEmpty(token)) { Console.WriteLine("校验不通过"); return; } //redis校验这个token的有效性，确定来源是sso和确定会话没过期 string tokenKey = $"token:{token}"; bool isVaid = _cachelper.StringGet(tokenKey); //token无效 if (isVaid == false) { Console.WriteLine($"token无效,token:{token}"); context.Result = new StatusCodeResult(401); //返回鉴权失败 } } }
然后需要认证的控制器或方法头部加上[MyAuthorize]即能自动认证。
web1需要登录的页面
@{ ViewData["Title"] = "Home Page";}
欢迎来到Web1
Learn about 退出登录.
@section Scripts{ }
sso登录完要跳转回web1的页面
@* For more information on enabling MVC for empty projects, visit Layout = null;}
到这里web1的核心代码就完成了，web2的代码跟web1除了配置里面的加密key，其他全部一样，就不再贴出代码了，后面源码有。
到这里，就实现了一处登录，全部登录了。
2、一处退出，全部退出实现
一处退出，处处退出的流程像实现目标中的流程图，web1系统退出，跳转到SSO，让SSO发 For more information on enabling MVC for empty projects, visit id="form">
用户名：
密码：
这里的SessionCode是关键，作为一个全局code，系统登录会同步到个系统，用于统一退出登录时用
SSO的退出登录页面LogOut.cshtml
@* For more information on enabling MVC for empty projects, visit src="~/lib/jquery/dist/jquery.min.js">
退出登录接口：
/// /// 退出登录 /// /// /// [HttpPost] public async Task LogOutApp([FromBody] LogOutRequest request) { //删除全局会话 string sessionKey = $"SessionCode:{request.sessionCode}"; _cachelper.DeleteKey(sessionKey); var client = _ var param = new { sessionCode = request.sessionCode }; string jsonData = System.Text.Json.JsonSerializer.Serialize(param); StringContent paramContent = new StringContent(jsonData); //这里实战中是用数据库或缓存取 List urls = new List() { " " }; //这里可以异步mq处理，不阻塞返回 foreach (var url in urls) { //web1退出登录 var logOutResponse = await client.PostAsync(url, new StringContent(jsonData, Encoding.UTF8, "application/json")); string resultStr = await logOutResponse.Content.ReadAsStringAsync(); ResponseModel response = System.Text.Json.JsonSerializer.Deserialize(resultStr); if (response.code == 0) //成功 { Console.WriteLine($"url:{url},会话Id:{request.sessionCode},退出登录成功"); } else { Console.WriteLine($"url:{url},会话Id:{request.sessionCode},退出登录失败"); } }; return new ResponseModel().SetSuccess(); }
web1，web2的退出登录接口
/// /// 退出登录 /// /// /// [HttpPost] public ResponseModel LogOut([FromBody] LogOutRequest request) { string key = $"SessionCode:{request.SessionCode}"; //根据会话取出token string token = _cachelper.StringGet(key); if (!string.IsNullOrEmpty(token)) { //清除token string tokenKey = $"token:{token}"; _cachelper.DeleteKey(tokenKey); } Console.WriteLine($"会话Code:{request.SessionCode}退出登录"); return new ResponseModel().SetSuccess(); }
到这里，一处退出，全部退出也完成了。
3、双token机制实现
token和refresh_token生成算法一样就可以了，只是token的有效期短，refresh_token的有效期长。
那刷新token时怎么知道这个是刷新token呢，SSO生成刷新token的时候，把它保存到缓存中，刷新token的时候判断缓存中有就是刷新token。
生成双token的代码：
/// /// 根据授权码,获取Token /// /// /// /// public ResponseModel GetTokenWithRefresh(string authCode) { ResponseModel result = new ResponseModel(); string key = $"AuthCode:{authCode}"; string clientIdCachekey = $"AuthCodeClientId:{authCode}"; string AuthCodeSessionTimeKey = $"AuthCodeSessionTime:{authCode}"; //根据授权码获取用户信息 CurrentUserModel currentUserModel = _cachelper.StringGet(key); if (currentUserModel == null) { throw new Exception("code无效"); } //清除authCode，只能用一次 _cachelper.DeleteKey(key); //获取应用配置 string clientId = _cachelper.StringGet(clientIdCachekey); //刷新token过期时间 DateTime sessionExpiryTime = _cachelper.StringGet(AuthCodeSessionTimeKey); DateTime tokenExpiryTime = DateTime.Now.AddMinutes(10);//token过期时间10分钟 //如果刷新token有过期期比token默认时间短，把token过期时间设成和刷新token一样 if (sessionExpiryTime > DateTime.Now && sessionExpiryTime < tokenExpiryTime) { tokenExpiryTime = sessionExpiryTime; } //获取访问token string token = this.IssueToken(currentUserModel, clientId, (sessionExpiryTime - DateTime.Now).TotalSeconds);if (sessionExpiryTime != default(DateTime)) { refreshTokenExpiry = sessionExpiryTime - DateTime.Now; } else { refreshTokenExpiry = TimeSpan.FromSeconds(60 * 60 * 24);//默认24小时 } //获取刷新token string refreshToken = this.IssueToken(currentUserModel, clientId, refreshTokenExpiry.TotalSeconds); //缓存刷新token _cachelper.StringSet(refreshToken, currentUserModel, refreshTokenExpiry); result.SetSuccess(new GetTokenDTO() { token = token, refreshToken = refreshToken, expires = 60 * 10 }); Console.WriteLine($"client_id:{clientId}获取token,有效期:{sessionExpiryTime.ToString("yyyy-MM-dd HH:mm:ss")},token:{token}"); return result; }
根据刷新token获取token代码：
/// /// 根据刷新Token获取Token /// /// /// /// public string GetTokenByRefresh(string refreshToken, string clientId) { //刷新Token是否在缓存 CurrentUserModel currentUserModel = _cachelper.StringGet($"RefreshToken:{refreshToken}"); if(currentUserModel==null) { return String.Empty; } //刷新token过期时间 DateTime refreshTokenExpiry = _cachelper.StringGet($"RefreshTokenExpiry:{refreshToken}"); //token默认时间为600s double tokenExpiry = 600; //如果刷新token的过期时间不到600s了，token过期时间为刷新token的过期时间 if(refreshTokenExpiry>DateTime.Now&&refreshTokenExpiry四、效果演示
这里项目的SSO地址是：，web1地址是：在最后加入
127.0.0.1 sso.com127.0.0.1 web1.com127.0.0.1 web2.com
这样得到新的地址，SSO地址:，web1地址是：这里一开始，访问 提取码：qcn1
