一、概念

大多数软件的相互沟通图：客户端与Web应用程序的访问、应用与Web api、api与api……相互沟通则需要授权、身份验证

技术分享

IdentityServer3的功能：Web认证、SSO单点登录、Web Api访问权限（常用的这三个）

OP:OpenID Provider

IP：Id Provider

STS:安全令牌服务

Scope(身份、资源)

用户(User)访问客户端、客户端（Client: 如Web或APP）向IdentityServer请求token,OP返回身份token\访问token，每一种资源都有一个标识范围（身份信息，授权资源信息都有一个对应的scope标识），OP会获取资源（RP）的Scope

技术分享

二、示例

1、新建一个控制台应用作为IdentityServer

安装：install-package identityserver3

新建Client.cs：在IdentityServer注册Client信息

using IdentityServer3.Core.Models;
using System.Collections.Generic;

namespace IdSrv
{
    static class Clients
    {
        public static List<Client> Get()
        {
            return new List<Client>
            {
                // no human involved
                new Client
                {
                    ClientName = "Silicon-only Client",
                    ClientId = "silicon",
                    Enabled = true,
                    AccessTokenType = AccessTokenType.Reference,

                    Flow = Flows.ClientCredentials,
                    
                    ClientSecrets = new List<Secret>
                    {
                        new Secret("F621F470-9731-4A25-80EF-67A6F7C5F4B8".Sha256())
                    },
                    
                    AllowedScopes = new List<string>
                    {
                        "api1"
                    }
                },

                // human is involved
                new Client
                {
                    ClientName = "Silicon on behalf of Carbon Client",
                    ClientId = "carbon",
                    Enabled = true,
                    AccessTokenType = AccessTokenType.Reference,

                    Flow = Flows.ResourceOwner,
                    
                    ClientSecrets = new List<Secret>
                    {
                        new Secret("21B5F798-BE55-42BC-8AA8-0025B903DC3B".Sha256())
                    },

                    AllowedScopes = new List<string>
                    {
                        "api1"
                    }
                }
            };
        }
    }
}

Client.cs

Scopes.cs注册范围标识

using System.Collections.Generic;
using IdentityServer3.Core.Models;

namespace IdSrv
{
    static class Scopes
    {
        public static List<Scope> Get()
        {
            return new List<Scope>
            {
                new Scope
                {
                    Name = "api1"
                }
            };
        }
    }
}

Scopes.cs

Users.cs注册用户

using IdentityServer3.Core.Services.InMemory;
using System.Collections.Generic;

namespace IdSrv
{
    static class Users
    {
        public static List<InMemoryUser> Get()
        {
            return new List<InMemoryUser>
            {
                new InMemoryUser
                {
                    Username = "bob",
                    Password = "secret",
                    Subject = "1"
                },
                new InMemoryUser
                {
                    Username = "alice",
                    Password = "secret",
                    Subject = "2"
                }
            };
        }
    }
}

Users.cs

配置Owin；这里把IdentityServer作为Owin的中间件配置一下

using Owin;
using IdentityServer3.Core.Configuration;

namespace IdSrv
{
    class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            var options = new IdentityServerOptions
            {
                Factory = new IdentityServerServiceFactory()
                            .UseInMemoryClients(Clients.Get())
                            .UseInMemoryScopes(Scopes.Get())
                            .UseInMemoryUsers(Users.Get()),

                RequireSsl = false
            };

            app.UseIdentityServer(options);
        }
    }
}

Startup.cs

Program.cs

using Microsoft.Owin.Hosting;
using System;

namespace IdSrv
{
    class Program
    {
        static void Main(string[] args)
        {


            // hosting identityserver
            using (WebApp.Start<Startup>("http://localhost:5000"))
            {
                Console.WriteLine("server running...");
                Console.ReadLine();
            }
        }
    }
}

Program.cs

2、新建控制台应用作为Client

namespace Client
{
    class Program
    {
        static void Main(string[] args)
        {
            var response = GetClientToken();//获取令牌
            CallApi(response);//实用令牌访问资源

            response = GetUserToken();
            CallApi(response);
        }

        static void CallApi(TokenResponse response)
        {
            var client = new HttpClient();
            client.SetBearerToken(response.AccessToken);

            Console.WriteLine(client.GetStringAsync("http://localhost:14869/test").Result);
        }

        static TokenResponse GetClientToken()
        {
            var client = new TokenClient(
                "http://localhost:5000/connect/token",
                "silicon",
                "F621F470-9731-4A25-80EF-67A6F7C5F4B8");

            return client.RequestClientCredentialsAsync("api1").Result;
        }

        static TokenResponse GetUserToken()
        {
            var client = new TokenClient(
                "http://localhost:5000/connect/token",
                "carbon",
                "21B5F798-BE55-42BC-8AA8-0025B903DC3B");

            return client.RequestResourceOwnerPasswordAsync("bob", "secret", "api1").Result;
        }
    }
}

Program.cs

3、新建Web API作为资源（RP）

Owin配置

using Microsoft.Owin;
using Owin;
using System.Web.Http;
using IdentityServer3.AccessTokenValidation;

[assembly: OwinStartup(typeof(Apis.Startup))]

namespace Apis
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            // accept access tokens from identityserver and require a scope of ‘api1‘
            app.UseIdentityServerBearerTokenAuthentication(new IdentityServerBearerTokenAuthenticationOptions
                {
                    Authority = "http://localhost:5000",
                    ValidationMode = ValidationMode.ValidationEndpoint,

                    RequiredScopes = new[] { "api1" }
                });

            // configure web api
            var config = new HttpConfiguration();
            config.MapHttpAttributeRoutes();
            
            // require authentication for all controllers
            config.Filters.Add(new AuthorizeAttribute());

            app.UseWebApi(config);
        }
    }
}

Startup

Controller

using System.Security.Claims;
using System.Web.Http;

namespace Apis
{
    [Route("test")]
    public class TestController : ApiController
    {
        public IHttpActionResult Get()
        {
            var caller = User as ClaimsPrincipal;

            var subjectClaim = caller.FindFirst("sub");
            if (subjectClaim != null)
            {
                return Json(new
                {
                    message = "OK user",
                    client = caller.FindFirst("client_id").Value,
                    subject = subjectClaim.Value
                });
            }
            else
            {
                return Json(new
                {
                    message = "OK computer",
                    client = caller.FindFirst("client_id").Value
                });
            }
        }
    }
}
