鉴权架构图
一、服务列表和技术版本列表
1. 服务列表
2. 技术版本列表
二、Oauth2.0 核心接口和概念简介
1. Oauth2 对外暴露的重要端口(REST API接口)
1) 申请token接口/oauth/token
2) 校验token接口 /oauth/check_token
3) 授权接口/oauth/authorize
2. Oauth2 定义的角色
三、环境搭建
1. 启动Nacos注册中心
2. 创建Oauth2 Server 工程并注册到Nacos
数据库设计
oauth_client_details
oauth_access_token
oauth_refresh_token
sys_user
1) pom.xml
2) application.yml
3) 配置授权服务器
4) 配置资源服务器
5) 配置HttpSecurity
6) 集成mybatis基于数据库认证
3. 整合网关gateway
1) 创建一个网关服务实现请求转发到auth-server
2) pom.xml
3) 配置路由
4) 测试网关转发请求
四、将普通微服务配置为资源服务器由网关统一转发认证
1. 创建user-service
2. 配置资源服务器
3. 配置oauth2 client 统一转发请求
五、统一鉴权的四种模式验证
1. 授权码模式(authorization_code)
2. 简化模式(implicit)
3. 密码模式(password)
4. 客户端模式(client_credentials)
服务名称 | 说明 |
nacos-server | 服务注册中心，提供服务发现与注册功能。 |
springcloud-gateway | 提供网关服务，网关尽量不做鉴权相关的操作，主要将请求路由到各微服务，实现统一转发请求到授权服务器 |
oauth2-project | 提供授权服务，通过客户端认证模式，将所有从网关转发过来的请求进行认证和授权。 |
user-service | 用户服务，普通微服务，同时也是资源服务器，需要配置授权转发。 |
名称 | 组 | 版本 | 说明 |
Java version | 11 | 为了支持springboot最新版本，使用java 11 | |
|
| 2.6.3 | Spring boot 版本 |
|
| 2021.0.1 | Spring Cloud 版本 |
|
| 2021.0.1.0 | Spring Cloud Alibaba 版本 |
|
| 3.1.1 | Gateway 版本 |
|
| 2021.0.1.0 | Nacos服务发现版本 |
|
| 3.1.1 | 新版本gateway默认不支持 lb转发，因此需要添加此依赖支持与nacos转发的负载均衡 |
|
| 2.2.4.RELEASE | oauth2 安全框架 |
nacos-server | 2.0.4 | naocs 注册中心 | |
|
| 5.1.46 | 提供mysql驱动和数据源 |
|

| 2.6.3 | 提供redis支持 |
oauth2 是一个能由开发者定制的安全框架，我们可以借助oauth2来完成系统应用的授权和认证，从而达到保护应用安全的目的。
oauth2 框架中自了几个重要的API，我们用它前一定要熟悉以下的接口。
/oauth/token接口在org.springframework.security.oauth2.provider.endpoint里的TokenEndpoint类里， 该接口会以post请求方式对外提供以表单形式的认证方式，通过了就会返回带期限的token。
通过表单的形式提交, 通过后会返回一个带期限的access_token， 如何用客户端模式去申请token:
/oauth/check_token接口在org.springframework.security.oauth2.provider.endpoint包里的CheckTokenEndpoint类里，请求方式get和post都可以，可以看到需要一个token参数
校验成功后会返回客户端信息:
/oauth/authorize接口在org.springframework.security.oauth2.provider.endpoint包里的AuthorizationEndpoint， 该接口可用于授权模式的授权操作， 也可用于简化模式的直接申请token。
授权服务器: 给具有权限的资源拥有者对应的访问请求授权。
资源服务器: 受保护的资源，可以为静态资源、接口等。
资源拥有者: 具有该系统资源的拥有者，最终受益于用户。
客户端: 与用户和资源、授权服务器沟通的平台，如一个web应用客户端，QQ、微信以第三方形式登录的客户端。
理解了Oauth2的概念后，我们把注册中心、授权服务器、网关搭起来。

import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;

}
可以在WebSecurityConfigurerAdapter里configure方法里配置不需要拦截的url, 比如一些登录、登出地址， 默认登录页面用 .formLogin()。
package com.bing.cloud.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.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
/**
* SpringSecurity配置
*/
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Override
public void configure(HttpSecurity http) throws Exception {
http.csrf()
.disable()
.httpBasic()
.and()
.authorizeRequests()
// 配置可以直接访问的页面
.antMatchers("/login/**", "/logout/**", "/api/getCurrentUser")
.permitAll()
// 其余所有请求都要通过认证鉴权
.anyRequest()
.authenticated()
.and()
// 配置spring security默认的登录页面
.formLogin()
.permitAll();
}
}
当使用密码模式请求/oauth/token接口时，我们可以使用自己创建的数据库与oauth2进行集成，只需要重写UserDetailService里的loadUserByUserName(String username)方法即可。
创建SecurityUser对象，使用mybatisplus插件映射到sys_user表。
package com.bing.cloud.service.impl;
import com.bing.cloud.MessageConstant;
import com.bing.cloud.entity.SecurityUser;
import com.bing.cloud.service.UserService;
import com.google.gson.GsonBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.AccountExpiredException;
import org.springframework.security.authentication.DisabledException;
import org.springframework.security.authentication.LockedException;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Service;
import javax.annotation.PostConstruct;
import java.util.ArrayList;
import java.util.List;
/**
* 自定义用户服务
*/
@Service
public class CustomUserDetailServiceImpl implements UserDetailsService {
@Autowired
private UserService userService;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
// 基于数据库认证
SecurityUser userInfo = userService.selectUserByUserName(username);
if (!userInfo.isEnabled()) {
throw new DisabledException(MessageConstant.ACCOUNT_DISABLED);
} else if (userInfo.isAccountLocked()) {
throw new LockedException(MessageConstant.ACCOUNT_LOCKED);
} else if (userInfo.isAccountExpired()) {
throw new AccountExpiredException(MessageConstant.ACCOUNT_EXPIRED);
}
// 获取到所有的role, 把role写入到simpleGrantedAuthority里。
List<SimpleGrantedAuthority> authorities = new ArrayList<>();
// String password = passwordEncoder.encode(userInfo.getPassword());
return new User(username, userInfo.getPassword(), authorities);
}
}
如果需要配置一些role, 可以通过mybatis将role表里的角色添加到SimpleGrantedAuthority列表里。
上述操作如果无误后启动 Auth-Server,能在nacos 里发现注册成功即可。
如果还有不了解gateway的朋友，推荐抽点时间浏览一下以下的文章
Nacos源码系列(一) 源码编译_Dream_it_possible！的博客-CSDN博客_nacos源码编译
本节目标是创建一个网关服务，实现请求能通过nacos转发到auth-server服务器上。
网关的作用是为了统一请求的入口，因此不建议在网关里写入大量的鉴权逻辑，新建一个springboot工程

添加auth-service-routte路由，注意将uri设置为lb://oauth2-server-service，因为通过nacos转发时，会根据服务名进行负载均衡式的请求。
可以在predicates里配置StripPrefix=1, 转发到目标服务后会去掉Path里第一个"/"和第二个"/"里的内容。
server:
port: 9000
spring:
application:
name: gateway
cloud:
gateway:
discovery:
locator:
enabled: true
lower-case-service-id: true
routes:
- id: user-service #路由的ID
uri: lb://user-service

- Path=/user/**
filters:
- StripPrefix=1
- name: Retry
args:
retires: 1
statuses: BAD_GATEWAY
- id: auth-service-route
uri: lb://oauth2-server-service
predicates:

- Path=/auth-server/**
filters:

args:
retries: 1 # 调用失败需要进行重试的次数,比如因为网络原因出现502等
statuses: BAD_GATEWAY
- StripPrefix=1
nacos:

启动网关服务, 可以从控制台看到我们配置的路由和相关的规则。
首先在auth-server添加一个测试api: /api/hello，使用postman访问请求localhost:9000/auth-server/api/hello
解决用网关转发Lb时，一直报503的问题:
由于最新版spring cloud的gateway不支持负载均衡功能，因此需要手动添加一个loadbalancer依赖：
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-loadbalancer</artifactId>
</dependency>
重新刷新依赖、启动网关微服务，访问localhost:9000/auth-server/api/hello，响应代码为: 401, 说明请求正确的转发到auth-server:
在一个大型的分布式系统里，存在的微服务可能有几十个或者上百个，如何使用网关和oauth server来保护，我们可以将普通微服务的未认证的请求全部由网关转发给鉴权服务器。
同样集成nacos, oauth2,mybatis 等框架，运行起来后能在nacos中发现。
放了方便配置资源服务器，我们将所有需要认证的接口都带上/api前缀。
package com.bingbing.sh.config;
import org.springframework.context.annotation.Configuration;
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;
/**
* 资源服务器配置
*/
@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.anyRequest()
.authenticated()
.and()
.requestMatchers()
.antMatchers("/api/**");//配置需要保护的资源路径
}
}
需要注意client-id和client-secret要与数据库里保持一致，可以选择使用客户端模式的进行认证，另外ecurity.oauth2.resource.token-info-uri这个值配为:oauth2-server的/oauth/check_token。
在application.properties文件里添加以下配置:
security.oauth2.client.access-token-uri=http://localhost:9000/auth-server/oauth/token
security.oauth2.client.client-authentication-scheme=form
security.oauth2.client.client-id=client-app
security.oauth2.client.client-secret=asdfholu12josadf#
security.oauth2.client.grant-type=client_credentials
security.oauth2.resource.token-info-uri=http://localhost:9000/auth-server/oauth/check_token
我们在请求user-service里的接口时，可以跟踪一下源代码，看一下oauth2 在user-service做了哪些事？
首先把上述的properties里的配置给注释掉，进入OAuth2AuthenticationProcessingFilter在org.springframework.security.oauth2.provider.authentication包里。 .doFilter() 方法， doFilter()方法用来拦截进入的请求。
接着进入到OAuth2AuthenticationManager.authenticate方法:
然后进入到tokenServices.loadAuthentication()方法：
默认进入到DefaultTokenService里的loadAuthentication:
可以发现默认是进入到DefaultTokenService认证token的，我们可以推断出肯定是不行的，因为我在user-service的项目里没有配置授权服务器，简单讲user-service是没有授权功能的。
接着我们把注释的配置放开，然后进入到loadAuthentication方法，发现是通过RemoteTokenServices调用的，向我们配置的security.oauth2.resource.token-info-uri 地址发起了一个rest请求:
如果token是正确的话，/oauth/check_token接口会返回一个map给我们
我们需要基于数据库的进行认证，那么需要在数据库里也配置所有的授权模式。
在authorized_grant_types字段里配置4种模式，用"," 隔开: password,client_credentials,authorization_code,implicit，在配置可以在加一个refresh_token，用于支持刷新token。
授权码模式是现在最严密、最安全的一种认证模式，第三方应用先通过登录获取到一个授权码和directUrl, 然后携带授权码和directUrl去授权服务器请求token令牌, 其中direct_url配置在数据库里，参数中的grant_type为client_credentials。
第一步在浏览器中访问如下地址:
输入用户名和密码:
登录成功后会在地址栏上返回一个code,每次申请的code只能使用一次, 由于我没有配置/dashboard页面，因此会报404的错误:
拿到code后，使用postman采用授权码模式请求token：
再次用同样的code去请求就会报错:Invalid authorization code: n2jZMX，必须重新访问/oauth/authorize重新申请一个新的code才行。
简化模式是直接在浏览器中向授权服务器申请令牌，成功了就能拿到token，参数中的grant_type为token。
第一步在浏览器中输入:
其中 redirect_uri和grant_type均配置在数据库里，如果没有登录，那么会先输入用户名和密码，登录成功后，会在地址栏上显示出token和失效时间。
密码模式是用户向客户端提供用户名和密码，客户端使用这些信息向授权服务器去申请令牌，参数中的grant_type为password，需要客户端应用与服务器提供商高度信息，必须是同一家公司。
密码模式直接将客户端ID、secret、用户名和密码放在body的表单里，用postman发一个post请求。
body里的参数
客户端模式是指客户端用自己的名义而不是用户的身份去向授权服务器申请令牌。
用postman请求localhost:9010/oauth/token, body里的参数为：
以上就是搭建统一鉴权的所有流程，4种模式都可以使用，可根据不同的场景进行甄选。
