上篇中我们已经可以实现sso,并且为各个服务集成sso认证。本篇处理权限系统的角色问题,权限系统分两层,第一层为整体系统角色权限,区分app用户、后台用户、网站用户的接口权限,第二层为业务系统权限,对业务子系统各个岗位的人划分不同权限。
第一层的角色固化在代码中,如商家app用户,师傅app用户,订单系统用户,接单系统用户等,第二层角色可自定义,和现有系统的角色概念一致。权限系统需要读取其他各个子系统的权限列表(标记在控制器、action上),并在系统权限中定义第一层权限和第二层权限。然后自定义一个Authorize方法,在里面实现第一层、第二层权限的authentication认证。想要实现权限鉴定,首先需要在用户Claims中取得除用户id外必要的用户信息,所以先实现自定义Claims。
1.自定义Claims
2.MVC项目sso跳转
3.Authentication验证
自定义Claims
打开Authorize项目的Startup,可以看到AddAbpIdentityServer,查看源码,我们模仿abp的方式自己实现一个认证。考虑到需要读取数据库,所以卸载WebCore项目
先实现AddProtonIdentityServer扩展方法
![复制代码](https://common.cnblogs.com/images/copycode.gif)
using System; using System.IdentityModel.Tokens.Jwt; using Abp.Authorization.Users; using Abp.IdentityServer4; using Abp.Runtime.Security; using IdentityModel; using IdentityServer4.Services; using Microsoft.Extensions.DependencyInjection; using Microsoft.Extensions.DependencyInjection.Extensions; namespace Authorize.Validation { public static class IdentityServerBuilderExtensions { /// <summary> /// 一个简单的扩展,用于注册IdentityServer /// </summary> /// <typeparam name="TUser"></typeparam> /// <param name="builder"></param> /// <param name="optionsAction"></param> /// <returns></returns> public static IIdentityServerBuilder AddProtonIdentityServer<TUser>(this IIdentityServerBuilder builder, Action<AbpIdentityServerOptions> optionsAction = null) where TUser : AbpUser<TUser> { var options = new AbpIdentityServerOptions(); optionsAction?.Invoke(options); builder.AddAspNetIdentity<TUser>(); builder.AddProfileService<AbpProfileService<TUser>>(); builder.AddResourceOwnerValidator<ProtonResourceOwnerPasswordValidator<TUser>>(); builder.Services.Replace(ServiceDescriptor.Transient<IClaimsService, ProtonClaimService>()); if (options.UpdateAbpClaimTypes) { AbpClaimTypes.UserId = JwtClaimTypes.Subject; AbpClaimTypes.UserName = JwtClaimTypes.Name; AbpClaimTypes.Role = JwtClaimTypes.Role; } if (options.UpdateJwtSecurityTokenHandlerDefaultInboundClaimTypeMap) { JwtSecurityTokenHandler.DefaultInboundClaimTypeMap[AbpClaimTypes.UserId] = AbpClaimTypes.UserId; JwtSecurityTokenHandler.DefaultInboundClaimTypeMap[AbpClaimTypes.UserName] = AbpClaimTypes.UserName; JwtSecurityTokenHandler.DefaultInboundClaimTypeMap[AbpClaimTypes.Role] = AbpClaimTypes.Role; } return builder; } } }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
还需要自定义ProtonResourceOwnerPasswordValidator和ProtonClaimService并且替换具体实现,这里的ProtonResourceOwnerPasswordValidator没有修改abp默认的用户表。
![复制代码](https://common.cnblogs.com/images/copycode.gif)
using Abp.Authorization.Users; using Abp.Domain.Uow; using Abp.Json; using Abp.Runtime.Security; using IdentityModel; using IdentityServer4.AspNetIdentity; using IdentityServer4.Models; using IdentityServer4.Services; using IdentityServer4.Validation; using Microsoft.AspNetCore.Identity; using Microsoft.Extensions.Logging; using System.Collections.Generic; using System.Linq; using System.Security.Claims; using System.Threading.Tasks; namespace Authorize.Validation { /// <summary> /// 自定义 Resource owner password 验证器 /// </summary> /// <typeparam name="TUser"></typeparam> public class ProtonResourceOwnerPasswordValidator<TUser> : ResourceOwnerPasswordValidator<TUser> where TUser : AbpUser<TUser> { /// <summary> /// 使用真实数据库验证用户 /// </summary> protected UserManager<TUser> UserManager { get; } protected SignInManager<TUser> SignInManager { get; } protected ILogger<ResourceOwnerPasswordValidator<TUser>> Logger { get; } public ProtonResourceOwnerPasswordValidator( UserManager<TUser> userManager, SignInManager<TUser> signInManager, IEventService eventService, ILogger<ResourceOwnerPasswordValidator<TUser>> logger) : base( userManager, signInManager, eventService, logger) { UserManager = userManager; SignInManager = signInManager; Logger = logger; } [UnitOfWork] public override async Task ValidateAsync(ResourceOwnerPasswordValidationContext context) { var user = await UserManager.FindByNameAsync(context.UserName); if (user != null) { var result = await SignInManager.CheckPasswordSignInAsync(user, context.Password, true); if (result.Succeeded) { Logger.LogInformation("Credentials validated for username: {username}", context.UserName); //验证通过返回结果 //subjectId 为用户唯一标识 一般为用户id //authenticationMethod 描述自定义授权类型的认证方法 //authTime 授权时间 //claims 需要返回的用户身份信息单元 此处应该根据我们从数据库读取到的用户信息 添加Claims 如果是从数据库中读取角色信息,那么我们应该在此处添加 此处只返回必要的Claim var sub = await UserManager.GetUserIdAsync(user); var claims = GetAdditionalClaimsOrNull(user); context.Result = new GrantValidationResult( sub, OidcConstants.AuthenticationMethods.Password, claims); //Logger.LogInformation($"claims:{claims.Select(d => d.Type + ":" + d.Value).ToJsonString()}"); return; } else if (result.IsLockedOut) { Logger.LogInformation("Authentication failed for username: {username}, reason: locked out", context.UserName); } else if (result.IsNotAllowed) { Logger.LogInformation("Authentication failed for username: {username}, reason: not allowed", context.UserName); } else { Logger.LogInformation("Authentication failed for username: {username}, reason: invalid credentials", context.UserName); } } else { Logger.LogInformation("No user found matching username: {username}", context.UserName); } context.Result = new GrantValidationResult(TokenRequestErrors.InvalidGrant); } protected virtual IEnumerable<Claim> GetAdditionalClaimsOrNull(TUser user) { var additionalClaims = new List<Claim>(); if (user.TenantId.HasValue) { additionalClaims.Add(new Claim(AbpClaimTypes.TenantId, user.TenantId?.ToString())); } /* * 系统角色 * 如超级管理员,xx子系统管理员,xx子系统普通用户,xxApp普通用户等, * 角色列表被固化在代码中,sso系统中每个账户可拥有一个或多个系统角色,每个接口上有标记Authorize[Role="abc"],不属于角色列表的用户无法调用接口。 * 注意和业务角色的区分,两者是完全不同的概念。业务角色是指以往所说的同类权限的用户组集合。 */ additionalClaims.Add(new Claim(ProtonClaimTypes.SystemRole, "systemrole")); //从用户表取 /* * 直营商id * 类似于tenantid,但全部放在业务系统处理相关逻辑。可能会换成tenantid */ additionalClaims.Add(new Claim(ProtonClaimTypes.PartnerId, "0")); return additionalClaims; } } /// <summary> /// Proton自定义ClaimTypes /// </summary> public static class ProtonClaimTypes { public const string PartnerId = "partner_id"; public const string SystemRole = "system_role"; } }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
注意在GetAdditionalClaimsOrNull方法添加需要在api服务获取的Claim属性。ProtonClaimService代码如下:
![复制代码](https://common.cnblogs.com/images/copycode.gif)
using Abp.Json; using Abp.Runtime.Security; using IdentityModel; using IdentityServer4.Services; using Microsoft.Extensions.Logging; using System.Collections.Generic; using System.Linq; using System.Security.Claims; namespace Authorize.Validation { public class ProtonClaimService : DefaultClaimsService { public ProtonClaimService(IProfileService profile, ILogger<DefaultClaimsService> logger) : base(profile, logger) { } protected override IEnumerable<Claim> GetOptionalClaims(ClaimsPrincipal subject) { var claims = base.GetOptionalClaims(subject); var tenantClaim = subject.FindFirst(AbpClaimTypes.TenantId); if (tenantClaim != null) { claims = claims.Union(new[] { tenantClaim }); } var sysRoleClaim = subject.FindFirst(ProtonClaimTypes.SystemRole); if (sysRoleClaim != null) { claims = claims.Union(new[] { sysRoleClaim }); } var partnerIdClaim = subject.FindFirst(ProtonClaimTypes.PartnerId); if (partnerIdClaim != null) { claims = claims.Union(new[] { partnerIdClaim }); } Logger.LogInformation(claims.Select(d => d.Type + ":" + d.Value).ToJsonString()); return claims; } } }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
同样需要把必要的Claims都加上,否则api服务取不到。如果是自带的claims,想在api服务中取得,那么修改IdentityServerConfig.GetApiResources方法
![复制代码](https://common.cnblogs.com/images/copycode.gif)
/// <summary> /// 允许使用认证服务的api列表 /// </summary> /// <returns></returns> public static IEnumerable<ApiResource> GetApiResources() { return new List<ApiResource> { new ApiResource("serviceorder", "Default (all) API",new List<string>(){JwtClaimTypes.Role}), new ApiResource("servicepartner", "Default (all) API1"), }; }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
修改一下订单服务的Default控制器以适应测试数据
![复制代码](https://common.cnblogs.com/images/copycode.gif)
// GET: api/Default [HttpGet] [Authorize(Roles = "Admin")] public String Get() { return $"claims:{HttpContext.User.Claims.Select(d => d.Type+":"+d.Value).ToJsonString()}"; //return new string[] { $"{serviceName}: {DateTime.Now.ToString()} {Environment.MachineName} " + // $"OS: {Environment.OSVersion.VersionString}" }; } // GET: api/Default/5 [Authorize(Roles = "SuperAdmin")] [HttpGet("{id}", Name = "Get")] public string Get(int id) { return $"claims:{HttpContext.User.Claims.Select(d => d.Type + ":" + d.Value).ToJsonString()}"; return serviceName + ".value." + id; }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
设想的结果是,Admin角色可以访问/api/default接口,并且返回Claims数据集合,但无法访问/api/default/1接口,我们测试一下
从authorize服务取得token,然后用这个token请求/api/default
正常返回claims信息,继续请求/api/default/1
提示403 forbidden,测试通过
MVC项目sso跳转
authorize服务本身的api接口,未授权401时,也会跳转到Account/Login,就用这个来做测试。sso登录需要统一的登录页,
IdentityServer4官方提供了一个QuickstartUI组件,包含了登录、授权、查看权限等基本功能,可以基于此建立第一个版本
https://github.com/IdentityServer/IdentityServer4.Quickstart.UI
下载来代码后,我们需要以下3个文件夹,复制到Authorize服务Host项目下
修改AuthConfigurer
![复制代码](https://common.cnblogs.com/images/copycode.gif)
services.AddAuthentication().AddIdentityServerAuthentication(configuration["Authentication:JwtBearer:DefaultScheme"], options => { options.Authority = $"http://{configuration["Service:IP"]}:{configuration["Service:Port"]}/"; options.RequireHttpsMetadata = false; options.ApiName = "serviceauthorize"; });
![复制代码](https://common.cnblogs.com/images/copycode.gif)
启用CORS,支持跨域,这里直接用abp的代码,未做改变
![复制代码](https://common.cnblogs.com/images/copycode.gif)
// Configure CORS for angular2 UI services.AddCors( options => options.AddPolicy( _defaultCorsPolicyName, builder => builder .WithOrigins( // App:CorsOrigins in appsettings.json can contain more than one address separated by comma. _appConfiguration["App:CorsOrigins"] .Split(",", StringSplitOptions.RemoveEmptyEntries) .Select(o => o.RemovePostFix("/")) .ToArray() ) .AllowAnyHeader() .AllowAnyMethod() .AllowCredentials() ) );
![复制代码](https://common.cnblogs.com/images/copycode.gif)
app.UseCors(_defaultCorsPolicyName); // Enable CORS!
修改appsettings.json,增加以下节点
"App": { "CorsOrigins": "http://localhost:21021,http://localhost:8080,http://localhost:8081,http://localhost:3000" },
去掉项目本身自带的HomeController(和demo的homecontroller冲突了),然后修改demo带来的每个控制器基类为AuthorizeControllerBase,比如:
![复制代码](https://common.cnblogs.com/images/copycode.gif)
/// <summary> /// This sample controller allows a user to revoke grants given to clients /// </summary> [SecurityHeaders] [Authorize] public class GrantsController : AuthorizeControllerBase { private readonly IIdentityServerInteractionService _interaction; private readonly IClientStore _clients; private readonly IResourceStore _resources; private readonly IEventService _events; public GrantsController(IIdentityServerInteractionService interaction, IClientStore clients, IResourceStore resources, IEventService events) { _interaction = interaction; _clients = clients; _resources = resources; _events = events; } //...... }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
最后,添加一个defaultcontroller用于测试,给Get方法添加Authorize标记
![复制代码](https://common.cnblogs.com/images/copycode.gif)
[DontWrapResult] [Route("api/[controller]")] public class DefaultController : AuthorizeControllerBase { private string serviceName = string.Empty; public IConfiguration Configuration { get; } public DefaultController(IConfiguration configuration) { Configuration = configuration; serviceName = Configuration["Service:Name"]; } // GET: api/Default [HttpGet] [Authorize] public IEnumerable<string> Get() { return new string[] { $"{serviceName}: {DateTime.Now.ToString()} {Environment.MachineName} " + $"OS: {Environment.OSVersion.VersionString}" }; } // other methods }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
运行项目,可以顺利打开http://localhost:21021/Account/Login
访问/api/default,会跳转到login,输入用户名密码登录后,可以访问到api/default这个受权限保护的接口,在实际mvc应用中,这个接口就是视图页
接下来处理新建一个mvc应用来实现上述功能。建立mvc应用是因为现有后端开发可以先行开发mpa应用,如果想开发spa,则需要单独招聘前端人员。mvc应用只提供视图,不提供任何其他接口,应用前端通过api网关直接向service请求数据,这是为了以后mpa转变为spa更方便。
权限问题,mtn系统可以管理整个系统的用户,用户的系统角色属性可能是商家app用户,师傅app用户,mtn管理员,mtn普通用户,order管理员,order普通用户等。一个用户可以有多个系统角色。mtn系统对每个系统角色都可以自定义权限范围,权限全集是所有页面权限(来自mpa应用或spa自定义的规则)和接口权限。mtn管理员在进入mtn系统后,可以添加mtn系统的业务角色,指定每个业务角色的权限(在全集内),还可以管理mtn系统的用户(从authorize服务取所有系统角色属于mtn管理员和mtn普通用户的所有用户),并为这些用户指定角色(可多个)。这部分功能放在基础服务实现。
从abp下载一个带login的模板,并用rename.ps1来重命名,注意CompanyName不要使用“Service”!,会导致rename时替换不应该替换的字符。去掉不相关的项目,只保留mvc
继承过程中遇到这个问题
![复制代码](https://common.cnblogs.com/images/copycode.gif)
IdentityServer4.Hosting.IdentityServerMiddleware[0] Unhandled exception: 系统找不到指定的文件。 Internal.Cryptography.CryptoThrowHelper+WindowsCryptographicException: 系统找不到指定的文件。 at System.Security.Cryptography.CngKey.Open(String keyName, CngProvider provider, CngKeyOpenOptions openOptions) at System.Security.Cryptography.CngKey.Open(String keyName, CngProvider provider) at Internal.Cryptography.Pal.CertificatePal.GetPrivateKey[T](Func`2 createCsp, Func`2 createCng) at Internal.Cryptography.Pal.CertificatePal.GetRSAPrivateKey() at System.Security.Cryptography.X509Certificates.X509Certificate2.get_PrivateKey() at Microsoft.IdentityModel.Tokens.X509SecurityKey.get_PrivateKey() at Microsoft.IdentityModel.Tokens.X509SecurityKey.get_PrivateKeyStatus()
![复制代码](https://common.cnblogs.com/images/copycode.gif)
解决方案:应用程序池,高级设置,修改“加载用户配置文件”为“True”即可!
https://blog.csdn.net/mushui0633/article/details/78596615
mvc应用访问authorize限制的页面,自动跳转到权限中心登录页,但输入账号密码登录成功后,不跳转,有以下几种错误信息:
Showing login: User is not active
Client requested access token - but client is not configured to receive access tokens via browser(服务端clients属性没开)

Executing ChallengeResult with authentication schemes ().
最后发现权限服务AddProtonIdentityServer方法中的AbpProfileService方法有问题,但是去掉后又导致role这个claim丢失,所以先写固定值,后面自己重写一套usermanager
增加一个ProtonProfileService
![复制代码](https://common.cnblogs.com/images/copycode.gif)
using Abp.Authorization.Users; using IdentityModel; using IdentityServer4.Models; using IdentityServer4.Services; using Microsoft.AspNetCore.Identity; using Microsoft.Extensions.Logging; using System.Linq; using System.Security.Claims; using System.Threading.Tasks; namespace Authorize.Validation { public class ProtonProfileService<TUser> : IProfileService where TUser : AbpUser<TUser> { protected UserManager<TUser> UserManager { get; } protected ILogger<ProtonProfileService<TUser>> Logger { get; } protected readonly IUserClaimsPrincipalFactory<TUser> ClaimsFactory; public ProtonProfileService( UserManager<TUser> userManager, ILogger<ProtonProfileService<TUser>> logger, IUserClaimsPrincipalFactory<TUser> claimsFactory) { UserManager = userManager; Logger = logger; ClaimsFactory = claimsFactory; } public async Task GetProfileDataAsync(ProfileDataRequestContext context) { //var sub = context.Subject?.GetSubjectId(); //if (sub == null) throw new Exception("No sub claim present"); //var user = await UserManager.FindByIdAsync(sub); //if (user == null) //{ // Logger?.LogWarning("No user found matching subject Id: {0}", sub); //} //else //{ // var principal = await ClaimsFactory.CreateAsync(user); // if (principal == null) throw new Exception("ClaimsFactory failed to create a principal"); // context.AddRequestedClaims(principal.Claims); //} var claims = context.Subject.Claims.ToList(); context.IssuedClaims = claims.ToList(); } public async Task IsActiveAsync(IsActiveContext context) { context.IsActive = true; } } }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
修改IdentityRegistrar中的Client
![复制代码](https://common.cnblogs.com/images/copycode.gif)
new Client { ClientId = "default_mvc_client", ClientName="default_name1114324324", AllowedGrantTypes = GrantTypes.Implicit, RedirectUris = { $"{Configuration["Clients:MvcClient:RedirectUri"]}signin-oidc" }, PostLogoutRedirectUris = { $"{Configuration["Clients:MvcClient:RedirectUri"]}signout-callback-oidc" }, AllowedScopes =new List<string> { IdentityServerConstants.StandardScopes.OpenId, IdentityServerConstants.StandardScopes.Profile, "serviceorder", }, AllowAccessTokensViaBrowser = true }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
将IdentityServerBuilderExtensions中的AbpProfileService替换为ProtonProfileService
修改ProtonResourceOwnerPasswordValidator中的GetAdditionalClaimsOrNull,增加一个role,后期重写时会替换为真实的用户角色
![复制代码](https://common.cnblogs.com/images/copycode.gif)
protected virtual IEnumerable<Claim> GetAdditionalClaimsOrNull(TUser user) { var additionalClaims = new List<Claim>(); if (user.TenantId.HasValue) { additionalClaims.Add(new Claim(AbpClaimTypes.TenantId, user.TenantId?.ToString())); } /* * 系统角色 * 如超级管理员,xx子系统管理员,xx子系统普通用户,xxApp普通用户等, * 角色列表被固化在代码中,sso系统中每个账户可拥有一个或多个系统角色,每个接口上有标记Authorize[Role="abc"],不属于角色列表的用户无法调用接口。 * 注意和业务角色的区分,两者是完全不同的概念。业务角色是指以往所说的同类权限的用户组集合。 */ additionalClaims.Add(new Claim(ProtonClaimTypes.SystemRole, "systemrole")); //从用户表取 /* * 业务角色 * 业务子系统的角色 */ additionalClaims.Add(new Claim(JwtClaimTypes.Role, "Admin")); /* * 直营商id * 类似于tenantid,但全部放在业务系统处理相关逻辑。可能会换成tenantid */ additionalClaims.Add(new Claim(ProtonClaimTypes.PartnerId, "0")); return additionalClaims; }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
修改appsettings.json
![复制代码](https://common.cnblogs.com/images/copycode.gif)
"Clients": { "MvcClient": { "RedirectUri": "http://192.168.8.157:5200/", "LogoutRedirectUri": "http://192.168.8.157:5200/" } }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
修改新增的mpa.maintenance项目的HomeController,给About这个action加上Authorize
![复制代码](https://common.cnblogs.com/images/copycode.gif)
using Microsoft.AspNetCore.Authorization; using Microsoft.AspNetCore.Mvc; namespace Mpa.Maintenance.Web.Controllers { public class HomeController : MaintenanceControllerBase { public ActionResult Index() { return View(); } [Authorize] public ActionResult About() { return View(); } } }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
修改其Startup.cs,其中Authority地址必须和认证服务地址一致,ClientId和权限服务配置的client信息一致。
![复制代码](https://common.cnblogs.com/images/copycode.gif)
using System; using System.IdentityModel.Tokens.Jwt; using Abp.AspNetCore; using Abp.Castle.Logging.Log4Net; //using Abp.EntityFrameworkCore; //using Mpa.Maintenance.EntityFrameworkCore; using Castle.Facilities.Logging; using Microsoft.AspNetCore.Builder; using Microsoft.AspNetCore.Hosting; using Microsoft.AspNetCore.Mvc; using Microsoft.Extensions.DependencyInjection; using Microsoft.Extensions.Logging; namespace Mpa.Maintenance.Web.Startup { public class Startup { public IServiceProvider ConfigureServices(IServiceCollection services) { //Configure DbContext //services.AddAbpDbContext<MaintenanceDbContext>(options => //{ // DbContextOptionsConfigurer.Configure(options.DbContextOptions, options.ConnectionString); //}); services.AddMvc(options => { options.Filters.Add(new AutoValidateAntiforgeryTokenAttribute()); }); JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear(); services.AddAuthentication(options => { options.DefaultScheme = "Cookies"; options.DefaultChallengeScheme = "oidc"; }) .AddCookie("Cookies") .AddOpenIdConnect("oidc", options => { options.SignInScheme = "Cookies"; options.Authority = "http://192.168.8.157:5100"; options.RequireHttpsMetadata = false; options.ClientId = "default_mvc_client"; options.ResponseType = "id_token token"; // allow to return access token options.SaveTokens = true; }); //Configure Abp and Dependency Injection return services.AddAbp<MaintenanceWebModule>(options => { //Configure Log4Net logging options.IocManager.IocContainer.AddFacility<LoggingFacility>( f => f.UseAbpLog4Net().WithConfig("log4net.config") ); }); } public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) { app.UseAbp(); //Initializes ABP framework. if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); //app.UseDatabaseErrorPage(); } else { app.UseExceptionHandler("/Error"); } app.UseAuthentication(); app.UseStaticFiles(); app.UseMvc(routes => { routes.MapRoute( name: "default", template: "{controller=Home}/{action=Index}/{id?}"); }); } } }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
再次测试,把之前的两个测试都重复一遍,验证api客户端和mvc客户端都可以正常使用
Authentication验证
有了基础的权限以后,我们需要考虑一下权限系统如何实现,然后再处理如何在controller,api,mpa_controller中获取session信息。authorize特性可以基于用户角色来验证,但这个角色必须固化在action上面,只能处理固化的系统角色,并不符合当前业务需求。当前业务需求是基于系统角色、业务角色来限制权限,需要灵活可配置每个角色的权限。所以需要自定义authorizeattribute,并设置一些属性来标记权限值(字符串),同时在控制器上也需要自定义attribute,这样就获得一个action的权限值,如“controllerName.actionName”,可以经由api接口或其他途径提供给authorize服务,在数据库中建立与角色的对应关系。最后再自定义一个filter用于验证权限即可。session的实现,可以经由Httpcontext.user.claims取得并赋值。
首先实现session功能,参考https://www.jianshu.com/p/930c10287e2a方式二。
第一步是确保所需的claims已经正常添加到context,然后我们基于abpSession进行扩展。新建一个IProtonSesson,继承IAbpSession,并添加我们需要的属性.
![复制代码](https://common.cnblogs.com/images/copycode.gif)
using Abp.Runtime.Session; namespace Proton.Web.Session { public interface IProtonSession : IAbpSession { string PartnerId { get; } //int UserId { get; } string SystemPermissions { get; } } }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
新建ProtonSession类,继承ClaimsAbpSession,IProtonSession,注意其中override重写了UserId字段
![复制代码](https://common.cnblogs.com/images/copycode.gif)
using Abp.Configuration.Startup; using Abp.Json; using Abp.MultiTenancy; using Abp.Runtime; using Abp.Runtime.Session; using Castle.Core.Logging; using IdentityModel; using Microsoft.AspNetCore.Http; using Proton.IdentityModel; using System; using System.Linq; namespace Proton.Web.Session { public class ProtonSession : ClaimsAbpSession, IProtonSession { private IHttpContextAccessor _accessor; public ILogger Logger { get; set; } public ProtonSession( IPrincipalAccessor principalAccessor, IMultiTenancyConfig multiTenancy, ITenantResolver tenantResolver, IAmbientScopeProvider<SessionOverride> sessionOverrideScopeProvider, IHttpContextAccessor accessor) : base( principalAccessor, multiTenancy, tenantResolver, sessionOverrideScopeProvider) { _accessor = accessor; Logger = NullLogger.Instance; } public string PartnerId => GetClaimValue(ProtonClaimTypes.PartnerId); public override long? UserId => Int32.Parse(GetClaimValue(JwtClaimTypes.Subject)); public string SystemPermissions => GetClaimValue(ProtonClaimTypes.SystemPermissions); private dynamic GetClaimValue(string claimType) { //var claimsPrincipal = PrincipalAccessor.Principal; //var claim = claimsPrincipal?.Claims.FirstOrDefault(c => c.Type == claimType); var claim = _accessor.HttpContext.User.Claims.FirstOrDefault(c => c.Type == claimType); Logger.InfoFormat(_accessor.HttpContext.User.Claims.Select(d => d.Type + ":" + d.Value).ToJsonString()); if (string.IsNullOrEmpty(claim?.Value)) { return null; } return claim.Value; } } }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
这里用到IHttpContextAccessor,参考https://www.cnblogs.com/liuxiaoji/p/6860122.html,需要在service提前注入实现。
services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>(); services.AddScoped<IProtonSession, ProtonSession>();
替换掉注入的AbpSession,在ControllerBase中处理
public new IProtonSession AbpSession { get; set; }
修改defaultcontroller来测试一下
![复制代码](https://common.cnblogs.com/images/copycode.gif)
public string Get() { var session = AbpSession; var userId = AbpSession.UserId; var partnerid = AbpSession.PartnerId; var r = $"claims:{HttpContext.User.Claims.Select(d => d.Type + ":" + d.Value).ToJsonString()}"; return $"session:{session.ToJsonString()};.\r\n" + r + "\r\n" + $"userId:{userId},partnerid:{partnerid}"; }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
可以看到成功取得userid,partnerid,并可以看到claims中所有的值。
下面处理权限验证。首先定义ProtonAuthorizeAttribute
![复制代码](https://common.cnblogs.com/images/copycode.gif)
using Abp.Extensions; using Microsoft.AspNetCore.Authorization; using System; namespace Proton.Web.Authorize { [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = true)] public class ProtonAuthorizeAttribute : AuthorizeAttribute { /// <summary> /// Action权限值名称,英文,同一控制器下唯一 /// </summary> public string AuthName { get; set; } /// <summary> /// 权限中文名,用于权限列表展示 /// </summary> public string AuthNameDisplay { get; set; } /// <summary> /// 构造函数 /// </summary> /// <param name="authName">权限值</param> /// <param name="displayName">权限值中文名称。</param> public ProtonAuthorizeAttribute(string authName, string displayName = "") { AuthName = authName; AuthNameDisplay = displayName.IsNullOrEmpty() ? authName : displayName; ; } } }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
定义ProtonControllerAttribute
![复制代码](https://common.cnblogs.com/images/copycode.gif)
using System; namespace Proton.Web.Authorize { public class ProtonControllerAttribute : Attribute { /// <summary> /// ControllerID,Guid,唯一值,用于和数据库对比记录 /// </summary> public string Id { get; set; } /// <summary> /// Controller权限值名称 /// </summary> public string ControllerName { get; set; } /// <summary> /// Controller中文名称,用于权限列表显示 /// </summary> public string ControllerNameDisplay { get; set; } public ProtonControllerAttribute(string id, string controllerName, string controllerNameDisplay = "") { Id = id; ControllerName = controllerName; ControllerNameDisplay = String.IsNullOrEmpty(controllerNameDisplay) ? controllerName : controllerNameDisplay; } } }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
其中预置的ProtonAuthNames如下:
![复制代码](https://common.cnblogs.com/images/copycode.gif)
using System.ComponentModel; namespace Proton.Web.Authorize { /// <summary> /// 页面元素预置权限类型 /// 可以自定义,只允许添加通用类型,特殊类型直接用字符串 /// </summary> public static class ProtonAuthNames { public const string List = "list"; public const string Detail = "look"; public const string Create = "create"; public const string Edit = "edit"; public const string Delete = "delete"; public const string Import = "import"; public const string Export = "export"; public const string Accept = "accept"; public const string Reject = "reject"; public const string CustomeOne = "custom1"; } }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
新建authorizefilter,定义AuthorizeFilter
![复制代码](https://common.cnblogs.com/images/copycode.gif)
using Abp.Collections.Extensions; using Microsoft.AspNetCore.Mvc; using Microsoft.AspNetCore.Mvc.Authorization; using Microsoft.AspNetCore.Mvc.Controllers; using Microsoft.AspNetCore.Mvc.Filters; using Proton.IdentityModel; using System.Collections.Generic; using System.Linq; namespace Proton.Web.Authorize { /// <summary> /// 权限验证拦截器 /// 当前只用于第一级系统角色验证,还需适应第二级业务角色验证 /// </summary> public class ProtonAuthorizationFilter : RequireHttpsAttribute { public override void OnAuthorization(AuthorizationFilterContext context) { if (context.Filters.Any(item => item is IAllowAnonymousFilter)) { return; } if (!(context.ActionDescriptor is ControllerActionDescriptor)) { return; } //不存在claims信息,需要验证登录 if (!context.HttpContext.User.Claims.Any()) { return; } var attributeList = new List<object>(); attributeList.AddRange((context.ActionDescriptor as ControllerActionDescriptor).MethodInfo.GetCustomAttributes(true)); attributeList.AddRange((context.ActionDescriptor as ControllerActionDescriptor).MethodInfo.DeclaringType.GetCustomAttributes(true)); //获取当前服务id,控制器id,控制器名称,action名称 var actionAttributes = attributeList.OfType<ProtonAuthorizeAttribute>().ToList(); string authName = actionAttributes.FirstOrDefault()?.AuthName; var controllerAttributes = attributeList.OfType<ProtonControllerAttribute>().ToList(); string controllerName = controllerAttributes.FirstOrDefault()?.ControllerName; var permissionStr = $"{controllerName}.{authName}"; //获取用户权限并判断 var claims = context.HttpContext.User.Claims; var permissions = claims.FirstOrDefault(c => c.Type == ProtonClaimTypes.SystemPermissions)?.Value.Split(','); permissions = new[] { "default_one.list" }; if (!permissions.IsNullOrEmpty() && permissions.Any(s => s.Equals(permissionStr))) { //授权通过 return; } //未授权返回403 context.Result = new StatusCodeResult(403); } } }
![复制代码](https://common.cnblogs.com/images/copycode.gif)
准备测试数据,修改DefaultController
![复制代码](https://common.cnblogs.com/images/copycode.gif)
[HttpGet] [ProtonAuthorize(ProtonAuthNames.List, "列表")] public string Get() { var session = AbpSession; var userId = AbpSession.UserId; var partnerid = AbpSession.PartnerId; var r = $"claims:{HttpContext.User.Claims.Select(d => d.Type + ":" + d.Value).ToJsonString()}"; return $"session:{session.ToJsonString()};.\r\n" + r + "\r\n" + $"userId:{userId},partnerid:{partnerid}"; } // GET: api/Default/5 [HttpGet("{id}", Name = "Get")] [ProtonAuthorize(ProtonAuthNames.Accept, "提交")] public string Get(int id) { return serviceName + ".value." + id; }

其中控制器也要加上Attribute
[ProtonController("72701F1B-4DAF-4E4C-AB87-9DA36CEC9D02", "default_one", "默认页面")] public class DefaultController : AuthorizeControllerBase
filter中定义了固化的permission="default_one.list"(claims没传回来,需要修改),所以理论上是/api/default和/api/default/1都需要登录,但前者有权限,可以读取内容,后者无权限,返回403.
测试结果表明,api访问可以正常取得所有claim,mpa应用和authorize服务不能,只能取到以下信息,这个问题后面在解决
