使用.Net Core + Vue + IdentityServer4 + Ocelot 实现一个简单的DEMO +源码

运行环境

Vue 使用的是D2admin:https://doc.d2admin.fairyever.com/zh/

Github地址:https://github.com/Fengddd/PermissionAdmin.git

Net Core的环境:Webapi 使用的是:NET Core SDK2.1 IdentityServer和Ocelot:NET Core SDK2.2

Github地址:https://github.com/Fengddd/IdentityServerOcelotDemo.git

我也是在初学阶段,所以有些地方可能描述的不是很清楚,可以下载源码查看,也可能大家一起交流,学习

建立IdentityServer4项目

根据 https://www.cnblogs.com/edisonchou/p/identityserver4_foundation_and_quickstart_01.html 根据Edison Zhou大佬的博客,配置好 QuickStart UI 以及IdentityServer的依赖项

新建IdentityServer4的配置文件IdentityConfig


   public static IEnumerable GetIdentityResources()
        {
            return new IdentityResource[]
            {
                new IdentityResources.OpenId(),
                new IdentityResources.Profile(),
                new IdentityResource("delimitClaim","delimitClaim",new List(){ "role", "name"}),  //在Claims添加role 和 name信息
            };
        }     
        public static IEnumerable GetApiResource()
        {
            return new List
            {              
                new ApiResource("identityServerApi", "identityServerApi"),
            };
        }
       public static IEnumerable GetClients()
        {
             new Client
                {                
                    ClientId = "js", //客户端Id
                    ClientName = "JavaScript Client", //客户端名称
                    AllowedGrantTypes = GrantTypes.Code, //授权模式
                    //AllowedGrantTypes = GrantTypes.Implicit,
                    RequirePkce = true,
                    RequireClientSecret = false,
                    RequireConsent = false, //禁用 consent 页面确认                    
                    AllowAccessTokensViaBrowser = true,
                    AlwaysIncludeUserClaimsInIdToken = true,
                    RedirectUris =
                    {
                        "http://localhost:8080/#/IdentityServerCallBack",  //登陆后回调页面 
                        "http://localhost:8080/#/IdentityServerRefreshToken" //刷新Token的页面
                    },
                    PostLogoutRedirectUris = { "http://localhost:8080/#/IdentityServerClient" },//注销退出后跳转的页面(登录页)                   
                    AllowedCorsOrigins = { "http://localhost:8080" }, //跨域
                    AccessTokenLifetime = 60, //AccessToken 的有效时间
                    AllowedScopes =
                    {
                        IdentityServerConstants.StandardScopes.OpenId,
                        IdentityServerConstants.StandardScopes.Profile,
                        "identityServerApi", //授权的Scopes
                        "delimitClaim" //Claims 信息
                    },
                    AllowOfflineAccess = true,                  
                }
        }

有时我们需要自定义验证以及自定义一些Claim的信息,所以需要实现 IProfileService 接口

public virtual Task GetProfileDataAsync(ProfileDataRequestContext context)
{
context.LogProfileRequest(Logger);
//判断是否有请求Claim信息
if (context.RequestedClaimTypes.Any())
{
var userClaims = new List
{
new Claim("demo1", "测试1"),
new Claim("demo2", "测试2"),
};
List userList = new List()
{
new TestUser(){SubjectId = "cfac01a9-ba15-4678-bccb-cc22d7896362",Password = "123456",Username="李锋",Claims = userClaims},
new TestUser(){SubjectId = "cfac01a9-ba15-4678-bccb-cc22d7855555",Password = "123456",Username="张三"},
};
TestUserStore userStore = new TestUserStore(userList);
//根据用户唯一标识查找用户信息
var user = userStore.FindBySubjectId(context.Subject.GetSubjectId());
if (user != null)
{
//调用此方法以后内部会进行过滤,只将用户请求的Claim加入到 context.IssuedClaims 集合中 这样我们的请求方便能正常获取到所需Claim
context.AddRequestedClaims(user.Claims);
}
//context.IssuedClaims=userClaims;
}
context.LogIssuedClaims(Logger);
return Task.CompletedTask;
}
///


/// 验证用户是否有效 例如:token创建或者验证
///

/// The context.
///
public virtual Task IsActiveAsync(IsActiveContext context)
{
Logger.LogDebug("IsActive called from: {caller}", context.Caller);
var userClaims = new List
{
new Claim("demo1", "测试1"),
new Claim("demo2", "测试2"),
};
List userList = new List()
{
new TestUser(){SubjectId = "cfac01a9-ba15-4678-bccb-cc22d7896362",Password = "123456",Username="李锋",Claims = userClaims},
new TestUser(){SubjectId = "cfac01a9-ba15-4678-bccb-cc22d7855555",Password = "123456",Username="张三"},
};
TestUserStore userStore = new TestUserStore(userList);
var user = userStore.FindBySubjectId(context.Subject.GetSubjectId());
context.IsActive = user?.IsActive == true;
return Task.CompletedTask;
}

其中关于Claims的地方这里做测试所以直接实例出来的数据,这里可以通过读取数据库进行验证,以及添加Claims的信息

在Startup 的ConfigureServices 注入IdentityServer信息 ,Configure下注册UseIdentityServer中间件

services.AddIdentityServer()
.AddDeveloperSigningCredential()
.AddInMemoryIdentityResources(IdentityConfig.GetIdentityResources())
.AddInMemoryApiResources(IdentityConfig.GetApiResource())
.AddInMemoryClients(IdentityConfig.GetClients())
//.AddTestUsers(IdentityConfig.GetUsers().ToList())
.AddProfileService(); //使用的是Code模式,使用自定义Claims信息
//.AddResourceOwnerValidator();

app.UseIdentityServer();

然后找到QuickStart中的登录方法,这里修改为从数据库读取验证用户信息

建立Vue项目

安装依赖项:oidc-client :npm install oidc-client --save axios:npm install axios --save

添加 IdentityServerClient 页面

添加 IdentityServerCallBack页面

添加 IdentityServerCallBack页面

访问IdentityServerClient 页面时会自动跳转到IdentityServer4的登录页面,输入账号密码,验证成功之后,会跳转到IdentityServerCallBack页面,然后在IdentityServerCallBack页面设置路由,跳转到目标页面

这里主要讲哈前端的配置,建议看https://www.cnblogs.com/FireworksEasyCool/p/10576911.html教程和oidc-client官方文档https://github.com/IdentityModel/oidc-client-js/wiki

注意使用:自动刷新Token使用自动刷新Token需要accessTokenExpiringNotificationTime和automaticSilentRenew 一起设置,当AccssToken要过期前:accessTokenExpiringNotificationTime设置的时间,会去请求

IdentityServer4 connect/token接口,刷新Token,请求到Token以后会触发addUserLoaded事件,我们可以把Token 保存在浏览器的缓存中(cookies,localstorage)中,然后在Axios中全局拦截请求,添加headers信息

Authorization 是token的信息,X-Claims是Claims的信息,传递Authorization 是为了IdentityServer 进行验证授权,X-Claims是为了后面结合Ocelot,携带一些Ocelot下游需要的参数进去

建立OcelotGateWay项目

添加Ocelot.json文件

"ReRoutes": [
{
"DownstreamPathTemplate": "/api/{url}",
"DownstreamScheme": "http",
"DownstreamHostAndPorts": [
{
"Host": "localhost",
"Port": 44375
}
],
"UpstreamPathTemplate": "/api/{url}",
"UpstreamHttpMethod": [ "Get", "Post" ],
"Priority": 2,
"AuthenticationOptions": {
"AuthenticationProviderKey": "IdentityServerKey",
"AllowScopes": [ "identityServerApi", "delimitClaim" ]
},
"RateLimitOptions": {
"ClientWhiteList": [ //白名单
],
"EnableRateLimiting": true, //启用限流
"Period": "1m",
"PeriodTimespan": 30,
"Limit": 5
},
"QoSOptions": {
"ExceptionsAllowedBeforeBreaking": 3,
"DurationOfBreak": 3000,
"TimeoutValue": 5000
}
]
}

AuthenticationOptions 表示认证的信息:IdentityServer4验证信息,AuthenticationProviderKey 填写 AddIdentityServerAuthentication 的key 一致,然后配置跨域,注册中间件

services.AddAuthentication()
.AddIdentityServerAuthentication("IdentityServerKey", options =>
{
options.Authority = "http://localhost:17491";
options.ApiName = "identityServerApi";
options.SupportedTokens = IdentityServer4.AccessTokenValidation.SupportedTokens.Both;
options.RequireHttpsMetadata = false;
});
services.AddOcelot()
.AddConsul()
.AddPolly();
//配置跨域处理
services.AddCors(options =>
{
options.AddPolicy("any", builder =>
{
builder.AllowAnyOrigin() //允许任何来源的主机访问
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials();//指定处理cookie
});
});
//配置Cors
app.UseCors("any");
app.UseAuthentication();

Program中添加

public static IWebHostBuilder CreateWebHostBuilder(string[] args)
{
return WebHost.CreateDefaultBuilder(args)
.ConfigureAppConfiguration((hostingContext, config) =>
{
config
.SetBasePath(hostingContext.HostingEnvironment.ContentRootPath)
.AddOcelot(hostingContext.HostingEnvironment) //ocelot合并配置文件,不能出现同样的一个端口,多个路由
.AddEnvironmentVariables();
})
.UseStartup();
}
