【Spring-Security】Re10 Oauth2协议 P1 授权码模式 & 密码模式

一、Oauth2协议：

第三方登录，即忘记本站密码，但是登录界面中提供了一些第三方登录，例如微信、支付宝、QQ、等等，通过第三方授权实现登录

第三方认证技术主要解决的时认证标准，各个平台的登录要遵循统一的接口协议

所以这里采用的方案是Oauth2

二、Spring-Security + Oauth2 环境搭建

创建一个空的SpringBoot项目：

删除不必要的文件

导入POM依赖坐标：

    private Collection<GrantedAuthority> authorities;


    @Override

        return false;
    }

    @Override
    public boolean isEnabled() {
        return false;
    }
}

Security安全配置：

package cn.zeal4j.configuration;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
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;

/**
 * @author Administrator
 * @file Spring-Security + Oauth2
 * @create 2020 09 29 11:35
 */
@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Bean
    public PasswordEncoder getPasswordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        // csrf
        httpSecurity.csrf().disable();

        // 登录，退出，授权放行
        httpSecurity.authorizeRequests().antMatchers("/login/**","/logout/**","/oauth/**/").permitAll();

        // 允许表单登录
        httpSecurity.formLogin().permitAll();

        // 其余请求权限拦截
        httpSecurity.authorizeRequests().anyRequest().authenticated();
    }
}

授权服务配置：

package cn.zeal4j.configuration;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
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;

/**
 * @author Administrator
 * @file Spring-Security + Oauth2
 * @create 2020 09 29 11:48
 * @description 授权服务器配置
 */
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.
                inMemory().
                withClient("admin").
                secret(passwordEncoder.encode("112233")).
                accessTokenValiditySeconds(3600). // 令牌有效时间 一小时
                redirectUris("http://www.baidu.com"). // 授权成功的跳转
                scopes("all").  // 所有范围
                authorizedGrantTypes("authorization_code");     // 授权类型：授权码模式
    }
}

资源服务配置：

package cn.zeal4j.configuration;
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;

/**
 * @author Administrator
 * @file Spring-Security + Oauth2
 * @create 2020 09 29 11:57
 */

@Configuration
@EnableResourceServer
public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity httpSecurity) throws Exception {

        httpSecurity.authorizeRequests().
                anyRequest().authenticated(). // 默认任何请求都需要授权
                and().
                requestMatchers().antMatchers("/user/**"); // 资源匹配规则
    }
}

登录逻辑：

package cn.zeal4j.service.impl;

import cn.zeal4j.domain.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.authority.AuthorityUtils;
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;

/**
 * @author Administrator
 * @file Spring-Security + Oauth2
 * @create 2020 09 29 11:35
 */
@Service
public class CustomUserDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Override
    public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
        String encode = passwordEncoder.encode("123456");
        return new User("admin", encode, AuthorityUtils.commaSeparatedStringToAuthorityList("admin"));
    }
}

User资源控制器：

package cn.zeal4j.controller;

import org.springframework.security.core.Authentication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * @author Administrator
 * @file Spring-Security + Oauth2
 * @create 2020 09 29 12:01
 */
@Controller
@RequestMapping("user")
public class UserController {

    /**
     * 获取当前用户
     * @param authentication
     * @return user/getCurrentUser
     */
    @RequestMapping("/getCurrentUser")
    @ResponseBody
    public Object getCurrentUser(Authentication authentication) {
        return authentication.getPrincipal();
    }

}

启动访问发现：

二、授权码模式实现：

发现生成的UserDetails实例默认设置的都是False，SpringSecurity一经权限判断，直接触发拦截

所以默认这里都要改成TRUE放行通过

    @Override
    public String getPassword() {
        return password;
    }

    @Override
    public String getUsername() {
        return username;
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return true;
    }

再次测试Oauth2地址：

http://localhost:8080/oauth/authorize?response_type=code&client_id=admin&redirect_uri=http://www.baidu.com&scope=all

点击选择Approve允许，点击Authorize进行授权

https://www.baidu.com/?code=G6ocWn

这个code就是我们的授权码

现在使用Postman进行测试：

1、先选择认证账号信息输入：

2、然后输入请求参数：

grant_type    authorization_code
code             你得到的授权码
cient_id        admin 
redirect_uri   http://www.baidu.com
scope            all

请求成功则会返回这个消息JSON

{
    "access_token": "4c562cc7-07c4-47b6-9a5b-537c4f4079cd",
    "token_type": "bearer",
    "expires_in": 43199,
    "scope": "all"
}

得到了许可Token

接着用Token访问资源获取接口：

http://localhost:8080/user/getCurrentUser

得到我们返回的数据：

{
    "username": "admin",
    "password": "$2a$10$tBlHK4KbNFsE7F7usl6AsODWWBkF4oS8Ak4qkaNbEFAsKykvXgH9i",
    "authorities": [
        {
            "authority": "admin"
        }
    ],
    "enabled": true,
    "accountNonLocked": true,
    "credentialsNonExpired": true,
    "accountNonExpired": true
}

如果令牌是错误的

{
    "error": "invalid_token",
    "error_description": "Invalid access token: 2287c3ab-3dc5-475e-97eb-bdffb2a78b8A"
}

三、密码模式授权实现：

package cn.zeal4j.configuration;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.core.userdetails.UserDetails;
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;

/**
 * @author Administrator
 * @file Spring-Security + Oauth2
 * @create 2020 09 29 11:48
 * @description 授权服务器配置
 */
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private PasswordEncoder passwordEncoder;
    
    @Autowired
    private AuthenticationManager authenticationManager;
    @Qualifier("customUserDetailsServiceImpl")
    @Autowired
    private UserDetailsService userDetailsService;

    /**
     * 使用密码模式需要的配置方法
     * @param endpoints
     * @throws Exception
     */
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.
                authenticationManager(authenticationManager).
                userDetailsService(userDetailsService);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.
                inMemory().
                withClient("admin").
                secret(passwordEncoder.encode("112233")).
                // accessTokenValiditySeconds(3600). // 令牌有效时间 一小时
                redirectUris("http://www.baidu.com"). // 授权成功的跳转
                scopes("all").  // 所有范围
                // authorizedGrantTypes("authorization_code");     // 授权类型：授权码模式
                authorizedGrantTypes("password");     // 授权类型：密码模式
    }
}

授权管理器Bean的注入：

package cn.zeal4j.configuration;

import org.omg.CORBA.PUBLIC_MEMBER;
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;

/**
 * @author Administrator
 * @file Spring-Security + Oauth2
 * @create 2020 09 29 11:35
 */
@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Bean
    public PasswordEncoder getPasswordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        httpSecurity.
                csrf().
                    disable().
                authorizeRequests().
                    antMatchers("/login/**","/logout/**","/oauth/**/").permitAll().
                    anyRequest().authenticated().
                    and().
                    formLogin().permitAll();


//        // csrf
//        httpSecurity.csrf().disable();
//
//        // 登录，退出，授权放行
//        httpSecurity.authorizeRequests().antMatchers("/login/**","/logout/**","/oauth/**/").permitAll();
//
//        // 允许表单登录
//        httpSecurity.formLogin().permitAll();
//
//        // 其余请求权限拦截
//        httpSecurity.authorizeRequests().anyRequest().authenticated();
    }
}

Postman请求的地址和前面的密码不变，但是更改授权参数

{
    "access_token": "8e51bdc3-50cd-42bd-b41c-28f06e5eca1f",
    "token_type": "bearer",
    "expires_in": 43199,
    "scope": "all"
}

用密码模式的令牌获取用户主体，也能拿到用户主体的信息：
