IdentitiServser4 + Mysql实现Authorization Server

 Identity Server 4官方文档:https://identityserver4.readthedocs.io/en/latest/

新建2个asp.net core 项目使用空模板

Auth 身份认证服务

Client客户端

Auth项目打开安装相关依赖 

IdentityServer4 和 EF 实体框架

Mysql EF Provider

Nlog日志组件

打开Startup.cs 文件配置 管道

配置 identity server

还是Startup.cs,编辑ConfigureServices方法:

添加Nlog日志

  services.AddLogging(logBuilder =>
            {
                logBuilder.AddNLog();
            });

日志配置文件(右键属性选择始终复制)

日志配置内容

xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <extensions>
    <add assembly="Nlog.Targets.Splunk"/>
  extensions>

  <targets async="true">
    <target name="asyncFile" xsi:type="File"
            layout="[${longdate}] [${level}] [${logger}] [${message}] ${newline} ${exception:format=tostring}"
            fileName="${basedir}/log/${shortdate}.txt"
            archiveFileName="${basedir}/log/archives/log.{#####}.txt"
            archiveAboveSize="102400000"
            archiveNumbering="Sequence"
            concurrentWrites="true"
            keepFileOpen="false"
            encoding="utf-8" />

    

    <target name="console" xsi:type="console"/>
  targets>

  <rules>
    
    <logger name="*" levels="Info,Error,Warn,Debug,Fatal" writeTo="asyncFile" />
    <logger name="*" minlevel="Error" writeTo="console" />

  rules>
nlog>

添加IdentityServer服务

services.AddIdentityServer()

添加身份验证方式

  services.AddIdentityServer()
                .AddResourceOwnerValidator()

ResourceOwnerPasswordValidator 类实现接口 IResourceOwnerPasswordValidator

实现验证ValidateAsync异步方法

 public async Task ValidateAsync(ResourceOwnerPasswordValidationContext context)
        {
            try
            {
                //根据context.UserName和context.Password与数据库的数据做校验,判断是否合法
                if (context.UserName == "wjk" && context.Password == "123")
                {
                    context.Result = new GrantValidationResult(
                        subject: context.UserName,
                        authenticationMethod: "custom",
                        claims: GetUserClaims());
                }
                else
                {

                    //验证失败
                    context.Result = new GrantValidationResult(TokenRequestErrors.InvalidGrant, "invalid custom credential");
                }
            }
            catch (System.Exception exception)
            {
                context.Result = new GrantValidationResult(TokenRequestErrors.InvalidGrant, "Invalid username or password");
                throw;
            }
        }

设置Claims

private static IEnumerable GetUserClaims()
        {
            return new[]
            {
                new Claim("uid", "1"),
                new Claim(JwtClaimTypes.Name,"wjk"),
                new Claim(JwtClaimTypes.GivenName, "GivenName"),
                new Claim(JwtClaimTypes.FamilyName, "yyy"),
                new Claim(JwtClaimTypes.Email, "[email protected]"),
                new Claim(JwtClaimTypes.Role,"admin")
            };
        }

设置验证方式

 services.AddIdentityServer()
                .AddResourceOwnerValidator()
                .AddSigningCredential(cert)

使用pfx 证书验证

cert证书读取

 var certAbsolutePath = PathResolver.ResolveCertConfigPath(Configuration["AuthOption:X509Certificate2FileName"], Environment);
 var cert = new X509Certificate2(certAbsolutePath, Configuration["AuthOption:X509Certificate2Password"]);
public static class PathResolver
    {
        public static string ResolveCertConfigPath(string configPath, IHostingEnvironment environment)
        {
            var start = new[] { "./", ".\\", "~/", "~\\" };
            if (start.Any(d => configPath.StartsWith(d)))
            {
                foreach (var item in start)
                {
                    configPath = configPath.TrimStart(item);
                }
                return Path.Combine(environment.ContentRootPath, configPath);
            }
            return configPath;
        }

        public static string TrimStart(this string target, string trimString)
        {
            if (string.IsNullOrEmpty(trimString)) return target;

            string result = target;
            while (result.StartsWith(trimString))
            {
                result = result.Substring(trimString.Length);
            }

            return result;
        }
    }

appsettings.json配置文件

  "AuthOption": {
    "X509Certificate2FileName": "./work.pfx",
    "X509Certificate2Password": "123456"
  }

证书生成方式:https://www.cnblogs.com/liuxiaoji/p/10790057.html

EF注入

var migrationsAssembly = typeof(Startup).GetTypeInfo().Assembly.GetName().Name;
 services.AddIdentityServer()
                .AddResourceOwnerValidator()
                .AddSigningCredential(cert)
                .AddConfigurationStore(options =>
                {
                    options.ConfigureDbContext = b =>
                        b.UseMySql(connectionString, sql => sql.MigrationsAssembly(migrationsAssembly));
                }).AddOperationalStore(options =>
                {
                    options.ConfigureDbContext = b =>
                        b.UseMySql(connectionString, sql => sql.MigrationsAssembly(migrationsAssembly));
                    options.EnableTokenCleanup = true;
                });

EF数据库迁移

 var connectionString = Configuration.GetConnectionString("Auth");
 "ConnectionStrings": {
    "Auth": "Server=localhost;database=auth;uid=root;pwd=123456;charset=UTF8;"
  },

执行命令

 切换到程序包管理器控制器,将默认项目设置为Auth,然后输入以下命令
 PersistedGrantDbContext
 Add-Migration -Name InitialIdentityServerConfigurationDbMigration -Context PersistedGrantDbContext -OutputDir Migrations/IdentityServer/PersistedGrantDb -Project Auth
 ConfigurationDbContext
 Add-Migration -Name InitialIdentityServerConfigurationDbMigration -Context ConfigurationDbContext -OutputDir Migrations/IdentityServer/ConfigurationDb -Project Auth
 命令将使用ConfigurationDbContext创建一个名为InitialIdentityServerConfigurationDbMigration 的迁移。迁移文件将输出到将默认项目设置为Auth项目的Migrations/IdentityServer/ConfigurationDb文件夹。

打开Startup.cs 文件配置 管道

        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)

            app.UseAuthentication();

            //添加MVC框架
            app.UseMvc();
        }
  public void ConfigureServices(IServiceCollection services)

添加 AuthController 用于测试token 身份验证
