oauth2 authorization code 大致流程
- 用户打开客户端后，客户端要求用户给予授权。
- 用户同意给予客户端授权。
- 客户端使用授权得到的code，向认证服务器申请token令牌。
- 认证服务器对客户端进行认证以后，确认无误，同意发放令牌。
- 客户端请求资源时携带token令牌，向资源服务器申请获取资源。
- 资源服务器确认令牌无误，同意向客户端开放资源。
security oauth2 整合的核心配置类
- 授权认证服务配置 AuthorizationServerConfiguration
- security 配置 SecurityConfiguration

授权认证服务配置类 AuthorizationServerConfiguration
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {
@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private MyUserDetailsService userDetailsService;
@Override
public void configure(final AuthorizationServerSecurityConfigurer oauthServer) throws Exception {

@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
PasswordEncoder passwordEncoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();
String secret = passwordEncoder.encode("secret");
clients.inMemory() // 使用in-memory存储
.withClient("client") // client_id
.secret(secret) // client_secret
//.autoApprove(true) ／／如果为true 则不会跳转到授权页面，而是直接同意授权返回code
.authorizedGrantTypes("authorization_code","refresh_token") // 该client允许的授权类型
.scopes("app"); // 允许的授权范围
}
@Override
public void configure(final AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.authenticationManager(authenticationManager).userDetailsService(userDetailsService)

web 安全配置 WebSecurityConfig

@Configuration
@EnableWebSecurity

auth.userDetailsService(userDetailsFitService).passwordEncoder(passwordEncoder());
auth.parentAuthenticationManager(authenticationManagerBean());
}
@Bean
public PasswordEncoder passwordEncoder(){
return PasswordEncoderFactories.createDelegatingPasswordEncoder();
}
}
url 注册配置 MvcConfig
@Configuration
public class MvcConfig implements WebMvcConfigurer {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/login").setViewName("login"); //自定义的登陆页面
registry.addViewController("/oauth/confirm_access").setViewName("oauth_approval"); //自定义的授权页面
}
}
# security 登陆认证 MyUserDetailsService
@Service
public class MyUserDetailsService implements UserDetailsService {
@Override
public UserDetails loadUserByUsername(String name) throws UsernameNotFoundException {

User user = mockUser();
return user;
}

PasswordEncoder passwordEncoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();
String pwd = passwordEncoder.encode("123456");
User user = new User("admin",pwd,authorities);
return user;
}

1. 访问oauth2 服务
client_id：第三方应用在授权服务器注册的 Id
response_type：固定值 code。
redirect_uri：授权服务器授权重定向哪儿的 URL。
scope：权限
state：随机字符串，可以省略
如果未登陆则出现登录页面，输入用户名：admin 密码：123456 登陆系统
image.png
2. 成功登陆后自动跳转到授权页面
image.png
- 点击“approve” 同意授权获取code返回：https://www.baidu.com/?code=1LerDZ&state=123
image.png - 点击“deny” 拒绝授权 返回：https://www.baidu.com/?error=access_denied&error_description=User%20denied%20access&state=123
image.png
3. 携带授权之后返回的code 获取token
http://localhost:18084/oauth/token?client_id=client&grant_type=authorization_code&redirect_uri=http://baidu.com&code=bzxoHn
如果没有登陆会出现登陆页面 输入：账号 client 密码 secret 登陆
image.png
这里的账号和密码 是我们注册的 client_id 和 client_secret

成功登陆后获取token

4.携带toekn 访问资源
