一、案例源码

微服务IASS 网关 sentinel 认证授权中心的搭建模板: 微服务IASS 网关 sentinel 认证授权中心的搭建模板

二、网关、sentinel熔断限流搭建

1、网关路由

将网关和对应微服务注册发现到Nacos中，采用网关负载均衡来路由各个微服务集群。

2、网关配置熔断限流策略

通过网关进行的限流策略有两个维度的限流：

1、网关维度；2、API分组维度的限流

两个维度限流的文件我将其存到Nacos中，便可实现Nacos动态更改熔断限流策略。

要注意的是，虽然熔断限流策略可以被sentinel的可视化操作界面进行动态更改，但更改后的内容也只是缓存在内存里的，若要下次重启仍然保留，需要将该对应的熔断限流策略复制粘贴到，Nacos的对应限流文件里，进行刷新。

网关限流:

Api分组的限流策略：

  

 测试结果：

通过访问测试我们可以看到，若该路径在API分组策略里，那么该路径会优先执行api分组限流里的策略，否则执行网关的统一限流策略。

3、网关的Token过滤器

授权服务器会给每个微服务在登录成功时授权对应的token,网关需要对这些请求进行判断已筛选出需要token验证的请求。

二、Oauth2授权服务器搭建

1、生成RSA密钥对

密钥对生成见我的这篇文章：

SpringBoot SpringSecurity JWT+Redis+RSA授权登录登出 验证码 前后端分离 分布式_Dragon Wu的博客-CSDN博客

2、授权服务器配置

主要依赖于：

        
            org.springframework.cloud
            spring-cloud-starter-oauth2
        

开启授权服务的配置类：

package com.dragonwu.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;
import org.springframework.security.oauth2.provider.token.store.KeyStoreKeyFactory;

/**

 **/
@EnableAuthorizationServer //开启授权服务器的功能
@Configuration
public class AuthorizationConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    @Qualifier("userServiceDetailsServiceImpl")
    private UserDetailsService userDetailsService;

    /*
    添加第三方的客户端
    */
    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("dragon-api")//第三方客户端的名称
                .secret(passwordEncoder.encode("dragon-secret"))//第三方客户端的密钥
                .scopes("all")//第三方客户端的授权范围
                .authorizedGrantTypes("password", "refresh_token")//密码模式、token刷新模式
                .accessTokenValiditySeconds(7 * 24 * 3600)//token的有效期
                .refreshTokenValiditySeconds(30 * 24 * 3600)//refresh_token的有效期
                .and()
                ///应用之间内部的访问形式
                .withClient("inside-app")
                .secret(passwordEncoder.encode("inside-secret"))
                .authorizedGrantTypes("client_credentials")//客户端授权，固定写法
                .scopes("all")
                .accessTokenValiditySeconds(7 * 24 * 3600);
        super.configure(clients);
    }

    /*
    配置验证管理器，UserDetailsService
     */
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(authenticationManager)
                .userDetailsService(userDetailsService)
                .tokenStore(jwtTokenStore()) //采用JWT存储token
                .tokenEnhancer(jwtAccessTokenConverter()); //token转换器
        super.configure(endpoints);
    }

    /*
    JWT token 存储
     */
    private TokenStore jwtTokenStore() {
        return new JwtTokenStore(jwtAccessTokenConverter());
    }

    /*
    JWT转换器
     */
    public JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter tokenConverter = new JwtAccessTokenConverter();

        //加载我们的私钥
        ClassPathResource classPathResource = new ClassPathResource("keys/dragonwu.jks");
        KeyStoreKeyFactory keyStoreKeyFactory = new KeyStoreKeyFactory(classPathResource, "dragonwu".toCharArray());//第二个参数为你生成密钥时输入的password
        tokenConverter.setKeyPair(keyStoreKeyFactory.getKeyPair("dragonwu", "dragonwu".toCharArray()));//第一个参数是生成密钥是的alias,第二个是password

        return tokenConverter;
    }
}

Security的配置类：

package com.dragonwu.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

/**
 * @author DragonWu
 * @since 2022-10-10 10:12
 **/
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    /*
    请求说明
     */
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
        http.authorizeRequests().anyRequest().authenticated();
    }

    /*
        认证管理
         */
    @Bean
    @Override
    protected AuthenticationManager authenticationManager() throws Exception {
        return super.authenticationManager();
    }

    /*
    加密器
     */
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

//    public static void main(String[] args) {
//        PasswordEncoder passwordEncoder=new BCryptPasswordEncoder();
//        String encode = passwordEncoder.encode("123456");
//        System.out.println(encode);
//    }
}

3、授权登录测试

 请求成功结果：

 用户登录类似，只需要更改对应参数即可：

refresh_token进行刷新登录： 与之前登录类似

服务器内部登录测试：

不同的是内部登录需要采用内部登录时的口令：

4、客户端登录 

开启对应的资源服务器

 资源服务器配置类：

package com.dragonwu;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configurers.ResourceServerSecurityConfigurer;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;
import org.springframework.util.FileCopyUtils;

import java.nio.charset.StandardCharsets;

/**
 * @author DragonWu
 * @since 2022-10-11 10:14
 **/
@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true) //开启权限访问注解
@EnableResourceServer //开启资源服务器
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

    //允许匿名访问的
    private static final String[] ALLOW_ASK = {
            "/login",//管理员登录
            "/user/login",//用户登录
            "/captcha",//验证码
    };
    //总数允许访问的
    private static final String[] ALWAYS_ALLOW_ASK = {
            "/v2/api-docs",
            "/swagger-resources/configuration/ui",//用来获取支持的动作
            "/swagger-resources",//用来获取api-docs的URI
            "/swagger-resources/configuration/security",//安全选项
            "/webjars/**",
            "/swagger-ui.html",//以上为api文档接口访问路径
            "**/public/**" //开放访问的资源
    };

    /*
    访问资源配置
     */
    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.csrf()
                .disable()
                .sessionManagement().disable()
                .authorizeRequests()
                .antMatchers(ALWAYS_ALLOW_ASK).permitAll()
                .antMatchers(ALLOW_ASK).anonymous()
                .antMatchers("/**").authenticated()
                .and().headers().cacheControl();
    }

    /*
     设置公钥
     */
    @Override
    public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
        resources.tokenStore(jwtTokenStore());

    }

    /*
    jwt token存储
     */
    private TokenStore jwtTokenStore() {
        return new JwtTokenStore(accessTokenConverter());
    }

    /*
    公钥解密的token转换器
     */
    @Bean // 放在ioc容器的
    public JwtAccessTokenConverter accessTokenConverter() {
        //resource 验证token（公钥） authorization 产生 token （私钥）
        JwtAccessTokenConverter tokenConverter = new JwtAccessTokenConverter();
        String s = null;
        try {
            ClassPathResource classPathResource = new ClassPathResource("keys/public.key");
            byte[] bytes = FileCopyUtils.copyToByteArray(classPathResource.getInputStream());
            s = new String(bytes, StandardCharsets.UTF_8);
        } catch (Exception ignored) {
        }
        tokenConverter.setVerifierKey(s);
        return tokenConverter;
    }
}

从代码中我们也不难看出，授权服务器拥有私钥可以对JWT token进行生成，而客户端志愿服务器仅有公钥对JWT token进行解密。

客户端访问授权服务器采用OpenFeign来访问

package com.dragonwu.feign;

import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.Data;

/**
 * @author DragonWu
 * @since 2022-10-11 8:48
 **/
@Data
public class JwtToken {
    @JsonProperty("access_token")
    private String accessToken;

    /*
    token的类型
     */
    @JsonProperty("token_type")
    private String tokenType;

    @JsonProperty("refresh_token")
    private String refreshToken;

    /*
    过期时间
     */
    @JsonProperty("expires_in")
    private Long expiresIn;

    /*
    token的范围
     */
    private String scope;

    /*
    颁发的凭证
     */
    private String jti;
}

Feign接口

package com.dragonwu.feign;

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestHeader;
import org.springframework.web.bind.annotation.RequestParam;

/**
 * @author DragonWu
 * @since 2022-10-11 8:52
 **/
@FeignClient(value = "authorization-server")
public interface OAuth2FeignClient {

    @PostMapping("/oauth/token")
    ResponseEntity getToken(
            @RequestParam("grant_type") String grantType,//授权类型
            @RequestParam("username") String username,//用户名
            @RequestParam("password") String password,//用户密码
            @RequestParam("login_type") String loginType,//登录的类型
            @RequestHeader("authorization") String basicToken//Basic ZHJhZ29uLWFwaTpkcmFnb24tc2VjcmV0 由第三方加密出来的值
    );
}

登录实现类：

package com.dragonwu.service.impl;

import com.alibaba.fastjson2.JSON;
import com.alibaba.fastjson2.JSONArray;
import com.alibaba.fastjson2.JSONObject;
import com.dragonwu.entity.SysMenu;
import com.dragonwu.feign.JwtToken;

import org.springframework.http.ResponseEntity;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.jwt.Jwt;
import org.springframework.security.jwt.JwtHelper;
import org.springframework.stereotype.Service;

import java.util.List;
import java.util.stream.Collectors;

/**

 * @since 2022-10-11 8:42
 **/
@Service
public class SysLoginServiceImpl implements SysLoginService {

    @Autowired
    private OAuth2FeignClient oAuth2FeignClient;

    @Value("${basic.token:Basic ZHJhZ29uLWFwaTpkcmFnb24tc2VjcmV0}")
    private String basicToken;

    @Autowired
    private ISysMenuService sysMenuService;

    @Override
    public LoginResult login(String username, String password) throws RuntimeException{
        System.out.println("用户："+username+"开始登录...");
        //1、获取token 远程调用authorization-server 的该服务
        ResponseEntity tokenResponseEntity = oAuth2FeignClient.getToken("password", username, password, "admin_type", basicToken);
        if(tokenResponseEntity.getStatusCode()!= HttpStatus.OK){
            throw new RuntimeException("token获取失败");
        }
        JwtToken jwtToken=tokenResponseEntity.getBody();
        System.out.println("远程调用授权服务器成功，获取的token为："+ JSON.toJSONString(jwtToken));
        assert jwtToken != null;
        String token=jwtToken.getAccessToken();

        //2、查询我们的菜单数据
        Jwt jwt= JwtHelper.decode(token);//解析jwt
        String jwtJsonStr=jwt.getClaims();//获得解析后的数据
        JSONObject jwtJson=JSON.parseObject(jwtJsonStr);//将解析后的数据转为json格式
        Long userId=Long.valueOf(jwtJson.getString("user_name"));//json中的user_name就是之前登录时存入的用户id

        List menus=sysMenuService.getMenuByUserId(userId);//通过用户id获取到对应的菜单

        //3、权限数据怎么查询-->不需要查询的，因为我们的jwt里面已包含了
        JSONArray authoritiesJsonArray=jwtJson.getJSONArray("authorities");
        List authorities=authoritiesJsonArray.stream()//组装我们的权限数据
                .map(authorityJson->new SimpleGrantedAuthority(authorityJson.toString()))
                .collect(Collectors.toList());

        return new LoginResult(token,menus,authorities);
    }
}

三、最终登录测试

 

可以看到次时我们通过网关去访问admin-service的login接口，admin-service此时做资源服务器，通过authorization-server进行授权登录。

请求路线：

url-->gateway-->admin-service-->authorization-server

--授权成功，颁发token-->admin-service-->响应。 

案例见代码，后续还会优化代码。
