Java中OAuth2.0第三方授权原理与实战

2022-11-13 09:11:53 原理 第三方 实战

RFC6749

OAuth2的官方文档在RFC6749：https://datatracker.ietf.org/doc/html/rfc6749

以王者荣耀请求微信登录的过程为例

  • A：Client申请访问用户资源
  • B：用户授权（过程较复杂）一次有效
  • C：Client向Server请求一个长时间有效的token
  • D：返回token
  • E：使用token访问资源

OAuth 2.0授权4大模式

授权码模式：完整、严密，第三方认证和授权的最主流实现

  • A：APP请求微信登录
  • B：用户信息验证
  • C：返回只能使用一次的授权码
  • D：APP把授权码发给后台服务，服务请求微信登录请求一个长期有效的token
  • E：返回长期有效的token

token只有APP的后台服务和微信的后台才有，二者之间使用token通信，保证数据不易泄露到后台黑客

简化模式：令牌用户可见，移动端的常用实现手段

  • A：APP请求微信登录
  • B：用户信息验证
  • C：直接返回一个长期有效的token

密码模式：用户名密码都返回

  • A：用户把用户名 + 密码发送给APP
  • B：APP可以直接用账号 + 密码访问微信后台

客户端模式：后台内容应用之间进行访问

微信登录会为APP分配一个内部的特定用户名和密码，APP用这个账号 + 密码和微信沟通，微信返回一个token，APP可以用这个token做很多部门自身的事情

合同到期后的续约机制

通常拿到Access token时还会拿到一个Refresh token，可以用来延长token的有效期

  • F：token已过期
  • G：使用Refresh token和微信登录沟通，尝试延长token
  • H：重新返回一个新的token

SpringBoot的经典启动类：

package com.wjw.oauthclient;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

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

创建OAuth2的配置类：

package com.wjw.oauthclient.config;

import org.springframework.boot.autoconfigure.security.oauth2.client.EnableOAuth2Sso;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

//激活OAuth2 SSO客户端
@Configuration
@EnableOAuth2Sso
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .anyRequest()
            .authenticated()
            .and()
            .csrf()
            .disable();
    }
}

配置文件application.yaml：

security.oauth2.client.client-secret=my_client_secret
security.oauth2.client.client-id=my_client_id
security.oauth2.client.user-authorization-uri=http://localhost:9090/oauth/authorize
security.oauth2.client.access-token-uri=http://localhost:9090/oauth/token
security.oauth2.resource.user-info-uri=http://localhost:9090/user

server.port=8080

server.servlet.session.cookie.name=ut
  • 定义用户id为my_client_id，密码为my_client_secret
  • 定义“微信登录服务”为：http://localhost:9090/oauth/authorize
  • 请求长期有效token的地址为：http://localhost:9090/oauth/token
  • 拿到token后请求用户信息的地址为：http://localhost:9090/user

    </repository>
  </repositories>
  
</project>

创建SpringBoot启动类：

package com.wjw.oauthserver;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;

@SpringBootApplication
@EnableResourceServer
public class OauthServerApplication {
    
    public static void main(String[] args) {
        SpringApplication.run(OauthServerApplication.class, args);
    }
    
}

创建controller：

提供一个api接口，模拟资源服务器

package com.wjw.oauthserver.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.security.Principal;

@RestController
public class UserController {
    @GetMapping("/user")
    public Principal getCurrentUser(Principal principal) {
        return principal;
    }
}

创建oauth2的关键配置类：

package com.wjw.oauthserver.config;

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;

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
    @Autowired
    PasswordEncoder passwordEncoder;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory() // 在内存里
                .withClient("my_client_id")
                .secret(passwordEncoder.encode("my_client_secret")) // 加密密码
                .autoApprove(true)  // 允许所有子类用户登录
                .redirectUris("http://localhost:8080/login")    // 反跳会登录页面
                .scopes("all")
                .accessTokenValiditySeconds(3600)
                .authorizedGrantTypes("authorization_code");    // 4大模式里的授权码模式
    }
}

现在需要提供一个登录页面让用户输入用户名和密码，并设置一个管理员账户：

package com.wjw.oauthserver.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
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;

@Configuration
@EnableWebSecurity
@Order(1)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Bean
    PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.requestMatchers()
                .antMatchers("/login")
                .antMatchers("/oauth/authorize")
                .and()
                .authorizeRequests().anyRequest().authenticated()
                .and()
                .fORMLogin()
                .permitAll()
                .and()
                .csrf().disable();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("wjw")
                .password(passwordEncoder().encode("123456"))
                .roles("admin");
    }
}

配置文件application.yaml：

server.port=9090

分别启动oauth-server和oauth-client进行测试：
访问localhost:8080/hello

访问hello时会重定向到login

访问登录时又会重定向到微信登录：

之后又会重定向到：

输入账户名+密码：

继续看控制台：
登录成功后还是会被重定向

此时再访问就会有授权码了（只能用一次）：

此时浏览器拿着授权码才去真正请求王者荣耀的hello接口（浏览器自动使用授权码交换token，对用户透明）：

王者荣耀使用授权码请求微信得到一个token和用户信息并返回给浏览器，浏览器再使用这个token调王者荣耀的hello接口拿用户信息：
