Oauth2使用postman登录获取token

  1. 网关请求拦截-(CheckJwtFilter.java)

    package com.xiaoge.config;

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.xiaoge.constant.GatewayConstant;
import org.apache.commons.lang.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.gateway.filter.GatewayFilter;
import org.springframework.cloud.gateway.filter.GatewayFilterChain;
import org.springframework.cloud.gateway.filter.GlobalFilter;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.Ordered;
import org.springframework.core.io.buffer.DataBuffer;
import org.springframework.core.io.buffer.DataBufferFactory;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.http.server.reactive.ServerHttpResponse;
import org.springframework.util.CollectionUtils;
import org.springframework.web.server.ServerWebExchange;
import reactor.core.publisher.Mono;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

/**
 * @Classname CheckJwtFilter
 * @Date 2022/3/20 下午4:49
 * @Created by xiaoge
 * @Description TODO
 */
@Configuration
public class CheckJwtFilter implements GlobalFilter, Ordered {

    @Autowired
    private StringRedisTemplate redisTemplate;

    /**
     * 过滤请求, 判断是否有jwt, 有放行, 没拦截
     * @param exchange
     * @param chain
     * @return
     */
    @Override
    public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
        ServerHttpRequest request = exchange.getRequest();

        // 获取路径
        String path = request.getURI().getPath();

        // 判断该路径是否在放行路径中
        if (GatewayConstant.ALLOW_PATH.contains(path)) {
            return chain.filter(exchange);
        }

        // 判断该请求头中是否包含Authorization
        HttpHeaders headers = request.getHeaders();
        List<String> list = headers.get(GatewayConstant.AUTHORIZATION);
        if (!CollectionUtils.isEmpty(list)) {
            String token = list.get(0);

            if (StringUtils.isNotBlank(token)) {
                String jwt = token.replace("bearer ", "");

                if (StringUtils.isNotBlank(jwt)) {
                    // 看redis是否还有该token
                    Boolean hasKey = redisTemplate.hasKey(GatewayConstant.OAUTH_PREFIX + jwt);

                    if(hasKey) {
                        return chain.filter(exchange);
                    }
                }
            }

        }

        // 这里就是没有 jwt 了，返回 401
        ServerHttpResponse response = exchange.getResponse();
        // 设置响应头
        response.getHeaders().add("content-type", "application/json;charset=utf-8");
        Map<String, Object> map = new HashMap<>();
        map.put("code", HttpStatus.UNAUTHORIZED.value());
        map.put("msg", "非法访问!");

        ObjectMapper objectMapper = new ObjectMapper();

        byte[] bytes = null;
        try {
            bytes = objectMapper.writeValueAsBytes(map);
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }

        DataBuffer buffer = response.bufferFactory().wrap(bytes);
        return response.writeWith(Mono.just(buffer));

    }


    /**
     * 执行顺序 越小越先 要比-1 小
     * @return
     */
    @Override
    public int getOrder() {
        return -2;
    }
}

  2. 网关配置把获取到的token存入redis-(GatewayConfig.java)它是把我们访问网关的路由转发到授权微服务

    package com.xiaoge.config;

import cn.hutool.json.JSONObject;
import cn.hutool.json.JSONUtil;
import com.xiaoge.constant.GatewayConstant;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.gateway.route.RouteLocator;
import org.springframework.cloud.gateway.route.builder.RouteLocatorBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.core.StringRedisTemplate;
import reactor.core.publisher.Mono;

import java.time.Duration;
import java.util.concurrent.TimeUnit;

/**
 * @Classname GatewayConfig
 * @Date 2022/3/20 下午5:18
 * @Created by xiaoge
 * @Description TODO
 */
@Configuration
public class GatewayConfig {

    @Autowired
    private StringRedisTemplate redisTemplate;

    /**
     * 描述: 给授权专门做的存入 token 路由
     *
     * @param builder:
     * @return org.springframework.cloud.gateway.route.RouteLocator */
    @Bean
    public RouteLocator routeLocator(RouteLocatorBuilder builder) {
        return builder .routes()
                .route("auth-server-router", r -> r.path("/oauth/**")
                        .filters(f -> f.modifyResponseBody(String.class, String.class, (exchanges, s) -> {
                            String path = exchanges.getRequest().getURI().getPath();
                            if ("/oauth/token".equals(path)) {
                                //如果是登录的请求，那么得到的 s 就是 token 的一套
                                JSONObject jsonObject = JSONUtil.parseObj(s);

                                // 判断jsonObject 是否包含access_token
                                if (jsonObject.containsKey("access_token")) {
                                    //如果包含 access_token 就放进 redis 里面
                                    // token值
                                    String access_token = jsonObject.getStr("access_token");
                                    // 过期时间
                                    Long expires_in = jsonObject.getLong("expires_in");

                                    // 存入redis中
                                    redisTemplate.opsForValue().set(GatewayConstant.OAUTH_PREFIX + access_token, "", Duration.ofSeconds(expires_in));
                                }
                            }
                            return Mono.just(s);
                        })).uri("lb://auth-server"))
                .build();

    }
}

  3. 授权服务认证配置-(AuthorizationConfig.java)

    package com.xiaoge.config;

import com.xiaoge.service.impl.UserDetailsServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.security.authentication.AuthenticationManager;
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.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;

import java.security.KeyPair;

/**

 * @DateTime: 2022/4/7 15:59
 * @Description:
 * 1. token的存储
 * 2. jwt的转换器
 * 3. 第三方应用
 * 4. endpoints暴露
 */
@Configuration
public class AuthorizationConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private UserDetailsServiceImpl userDetailsService;

    /**
     * 使用 jwt 存放 token
     * @return
     */
    @Bean
    public TokenStore tokenStore() {
        return new JwtTokenStore(jwtAccessTokenConverter());
    }


    /**
     * 使用非对称加密的方式
     * @return
     */
    @Bean
    public JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter jwtAccessTokenConverter = new JwtAccessTokenConverter();
        // 把私钥读到内存中
        ClassPathResource resource = new ClassPathResource("cxs-jwt.jks");
        // 创建一个钥匙工厂
        KeyStoreKeyFactory keyStoreKeyFactory = new KeyStoreKeyFactory(resource,"cxs123".toCharArray());
        // 获取钥匙, 传入钥匙别名
        KeyPair privateKey = keyStoreKeyFactory.getKeyPair("cxs-jwt");
        // 设置进转换器里面
        jwtAccessTokenConverter.setKeyPair(privateKey);
        return jwtAccessTokenConverter;
    }


    /**
     * 配置第三方应用
     * password 只要是登录都用这个授权方式
     * 客户端授权 用于微服务之间自发的进行远程调用时 资源服务器必须要token的情况, 当然也是可以放行服务提供者的接口的
     *
     *
     * 描述: 一个 web 平台，用于第三方访问
     * 一个 sxt 平台，内部访问的，例如 mq 里发起远程调用
     * @param clients
     * @throws Exception
     */
    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory() // 配置第三方引用
                    .withClient("web") // 浏览器
                    .secret(passwordEncoder.encode("web-secret")) // 密码加密方式
                    .scopes("all")  // 作用域
                    .authorizedGrantTypes("password") // 授权类型 密码授权
                    .accessTokenValiditySeconds(7200) // token的时间7200秒
                    .redirectUris("https://www.baidu.com") // token过期从定向地址
                    .and() // 上面是密码授权方式, 下面是客户端授权
                    .withClient("client") // 微服务之间自发的调用
                    .secret(passwordEncoder.encode("client-secret")) // 密码加密方式
                    .scopes("read") // 只读 业务方面的一个配置
                    .authorizedGrantTypes("client_credentials") // 授权类型  客户端授权
                    .accessTokenValiditySeconds(Integer.MAX_VALUE) // token过期时间 66年
                    .redirectUris("https://www.baidu.com");  // token过期从定向地址

    }


    /**
     * 暴露出去
     * @param endpoints
     * @throws Exception
     */
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints
                .userDetailsService(userDetailsService)  // 暴露密码登录实现类
                .authenticationManager(authenticationManager) // 暴露密码登录需要的认证管理器
                .tokenStore(tokenStore())  // 暴露tokenStore
                .accessTokenConverter(jwtAccessTokenConverter()); // 暴露jwt转换器
        super.configure(endpoints);
    }

}

  4. 授权服务安全配置-(WebSecurityConfig.java)

    package com.xiaoge.config;

import com.xiaoge.service.impl.UserDetailsServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

/**
 * @Author: ZhangXiao
 * @DateTime: 2022/4/7 15:56
 * @Description:
 */
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsServiceImpl userDetailsService;

    /**
     * 认证管理器 密码登录需要认证管理器
     * @return
     * @throws Exception
     */
    @Bean
    public AuthenticationManager authenticationManager() throws Exception {
        return super.authenticationManager();
    }


    /**
     * 走自己的登录 密码登录需要的
     * @param auth
     * @throws Exception
     */
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        //走自己的登录
        auth.userDetailsService(userDetailsService);
    }

}

  5. 授权服务登录-(UserDetailsServiceImpl.java)

    package com.xiaoge.service.impl;

import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.xiaoge.constant.AuthConstant;
import com.xiaoge.domain.SysUser;
import com.xiaoge.mapper.SysUserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import org.springframework.util.CollectionUtils;
import org.springframework.util.ObjectUtils;
import org.springframework.util.StringUtils;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;
import java.util.List;

/**
 * @Author: ZhangXiao
 * @DateTime: 2022/4/7 16:10
 * @Description:
 */
@Service
public class UserDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private SysUserMapper sysUserMapper;

    /**
     * 登录方法
     * @param username
     * @return
     * @throws UsernameNotFoundException
     */
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        // 获取request
        ServletRequestAttributes requestAttributes =  (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = requestAttributes.getRequest();

        // 获取请求头信息
        String loginType = request.getHeader(AuthConstant.LOGIN_TYPE);

        if (StringUtils.isEmpty(loginType)) {
            return null;
        }

        // 选择
        switch (loginType) {
            case AuthConstant.SYS_USER:
                // 后台用户 就查后台的sys_user表
                SysUser sysUser = sysUserMapper.selectOne(new LambdaQueryWrapper<SysUser>().eq(
                        SysUser::getUsername, username
                ));

                if (!ObjectUtils.isEmpty(sysUser)) {
                    // 查询权限
                    List<String> auths = sysUserMapper.findUserAuthsById(sysUser.getUserId());

                    if (!CollectionUtils.isEmpty(auths)) {
                        // 设置权限
                        sysUser.setAuths(auths);
                    }
                }
                return sysUser;
            case AuthConstant.MEMBER:
                // 前台用户
                return null;
            default:
                return null;

        }
    }
}

  6. 授权服务启动类-(AuthServerApplication.class) (一定要加这个认证注解EnableAuthorizationServer, 因为WebSecurityConfig配置了认证管理器)

    package com.xiaoge;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.context.annotation.Bean;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;

/**
 * @Author: ZhangXiao
 * @DateTime: 2022/4/7 15:36
 * @Description:
 */
@SpringBootApplication
@EnableAuthorizationServer // 开启授权服务器
@EnableEurekaClient  // 开启eureka客户端
@MapperScan(basePackages = "com.xiaoge.mapper")
public class AuthServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(AuthServerApplication.class, args);
    }


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

}

  7. postman-Authorization(web web-secret grant_type(认证方式)是AuthorizationConfig类中配置的)
