Spring Boot Security 整合 OAuth2 设计安全API接口服务

简介

OAuth是一个关于授权（authorization）的开放网络标准，在全世界得到广泛应用，目前的版本是2.0版。本文重点讲解Spring Boot项目对OAuth2进行的实现，如果你对OAuth2不是很了解，你可以先理解 OAuth 2.0 - 阮一峰，这是一篇对于oauth2很好的科普文章。

OAuth2概述

oauth2根据使用场景不同，分成了4种模式

• 授权码模式（authorization code）
• 简化模式（implicit）
• 密码模式（resource owner password credentials）
• 客户端模式（client credentials）

在项目中我们通常使用授权码模式，也是四种模式中最复杂的，通常网站中经常出现的微博，qq第三方登录，都会采用这个形式。

Oauth2授权主要由两部分组成：

• Authorization server：认证服务
• Resource server：资源服务

在实际项目中以上两个服务可以在一个服务器上，也可以分开部署。下面结合spring boot来说明如何使用。

快速上手

之前的文章已经对 Spring Security 进行了讲解，这一节对涉及到 Spring Security 的配置不详细讲解。若不了解 Spring Security 先移步到 Spring Boot Security 详解。

建表

客户端信息可以存储在内存、redis和数据库。在实际项目中通常使用redis和数据库存储。本文采用数据库。Spring 0Auth2 己经设计好了数据库的表，且不可变。表及字段说明参照：Oauth2数据库表说明 。

创建0Auth2数据库的脚本如下:

DROP TABLE IF EXISTS `clientdetails`;
DROP TABLE IF EXISTS `oauth_access_token`;
DROP TABLE IF EXISTS `oauth_approvals`;
DROP TABLE IF EXISTS `oauth_client_details`;
DROP TABLE IF EXISTS `oauth_client_token`;
DROP TABLE IF EXISTS `oauth_refresh_token`;

CREATE TABLE `clientdetails` (
  `appId` varchar(128) NOT NULL,
  `resourceIds` varchar(256) DEFAULT NULL,
  `appSecret` varchar(256) DEFAULT NULL,
  `scope` varchar(256) DEFAULT NULL,
  `grantTypes` varchar(256) DEFAULT NULL,
  `redirectUrl` varchar(256) DEFAULT NULL,
  `authorities` varchar(256) DEFAULT NULL,
  `access_token_validity` int(11) DEFAULT NULL,
  `refresh_token_validity` int(11) DEFAULT NULL,
  `additionalInformation` varchar(4096) DEFAULT NULL,
  `autoApproveScopes` varchar(256) DEFAULT NULL,
  PRIMARY KEY (`appId`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;


CREATE TABLE `oauth_access_token` (
  `token_id` varchar(256) DEFAULT NULL,
  `token` blob,
  `authentication_id` varchar(128) NOT NULL,
  `user_name` varchar(256) DEFAULT NULL,
  `client_id` varchar(256) DEFAULT NULL,
  `authentication` blob,
  `refresh_token` varchar(256) DEFAULT NULL,
  PRIMARY KEY (`authentication_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE `oauth_approvals` (
  `userId` varchar(256) DEFAULT NULL,
  `clientId` varchar(256) DEFAULT NULL,
  `scope` varchar(256) DEFAULT NULL,
  `status` varchar(10) DEFAULT NULL,
  `expiresAt` datetime DEFAULT NULL,
  `lastModifiedAt` datetime DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE `oauth_client_details` (
  `client_id` varchar(128) NOT NULL,
  `resource_ids` varchar(256) DEFAULT NULL,
  `client_secret` varchar(256) DEFAULT NULL,
  `scope` varchar(256) DEFAULT NULL,
  `authorized_grant_types` varchar(256) DEFAULT NULL,
  `web_server_redirect_uri` varchar(256) DEFAULT NULL,
  `authorities` varchar(256) DEFAULT NULL,
  `access_token_validity` int(11) DEFAULT NULL,
  `refresh_token_validity` int(11) DEFAULT NULL,
  `additional_information` varchar(4096) DEFAULT NULL,
  `autoapprove` varchar(256) DEFAULT NULL,
  PRIMARY KEY (`client_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE `oauth_client_token` (
  `token_id` varchar(256) DEFAULT NULL,
  `token` blob,
  `authentication_id` varchar(128) NOT NULL,
  `user_name` varchar(256) DEFAULT NULL,
  `client_id` varchar(256) DEFAULT NULL,
  PRIMARY KEY (`authentication_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

DROP TABLE IF EXISTS `oauth_code`;
CREATE TABLE `oauth_code` (
  `code` varchar(256) DEFAULT NULL,
  `authentication` blob
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE `oauth_refresh_token` (
  `token_id` varchar(256) DEFAULT NULL,
  `token` blob,
  `authentication` blob
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

为了测试方便，我们先插入一条客户端信息。

INSERT INTO `oauth_client_details` VALUES ('dev', '', 'dev', 'app', 'password,client_credentials,authorization_code,refresh_token', 'http://www.baidu.com', '', 3600, 3600, '{"country":"CN","country_code":"086"}', 'false');

用户、权限、角色用到的表如下:

DROP TABLE IF EXISTS `user`;
DROP TABLE IF EXISTS `role`;
DROP TABLE IF EXISTS `user_role`;
DROP TABLE IF EXISTS `role_permission`;
DROP TABLE IF EXISTS `permission`;

CREATE TABLE `user` (
`id` bigint(11) NOT NULL AUTO_INCREMENT,
`username` varchar(255) NOT NULL,
`password` varchar(255) NOT NULL,
PRIMARY KEY (`id`) 
);
CREATE TABLE `role` (
`id` bigint(11) NOT NULL AUTO_INCREMENT,
`name` varchar(255) NOT NULL,
PRIMARY KEY (`id`) 
);
CREATE TABLE `user_role` (
`user_id` bigint(11) NOT NULL,
`role_id` bigint(11) NOT NULL
);
CREATE TABLE `role_permission` (
`role_id` bigint(11) NOT NULL,
`permission_id` bigint(11) NOT NULL
);
CREATE TABLE `permission` (
`id` bigint(11) NOT NULL AUTO_INCREMENT,
`url` varchar(255) NOT NULL,
`name` varchar(255) NOT NULL,
`description` varchar(255) NULL,
`pid` bigint(11) NOT NULL,
PRIMARY KEY (`id`) 
);

INSERT INTO user (id, username, password) VALUES (1,'user','e10adc3949ba59abbe56e057f20f883e'); 
INSERT INTO user (id, username , password) VALUES (2,'admin','e10adc3949ba59abbe56e057f20f883e'); 
INSERT INTO role (id, name) VALUES (1,'USER');
INSERT INTO role (id, name) VALUES (2,'ADMIN');
INSERT INTO permission (id, url, name, pid) VALUES (1,'/**','',0);
INSERT INTO permission (id, url, name, pid) VALUES (2,'/**','',0);
INSERT INTO user_role (user_id, role_id) VALUES (1, 1);
INSERT INTO user_role (user_id, role_id) VALUES (2, 2);
INSERT INTO role_permission (role_id, permission_id) VALUES (1, 1);
INSERT INTO role_permission (role_id, permission_id) VALUES (2, 2);

SecurityConfig

支持password模式要配置AuthenticationManager

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private MyUserDetailsService userService;


    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {

        //校验用户
        auth.userDetailsService( userService ).passwordEncoder( new PasswordEncoder() {
            //对密码进行加密
            @Override
            public String encode(CharSequence charSequence) {
                System.out.println(charSequence.toString());
                return DigestUtils.md5DigestAsHex(charSequence.toString().getBytes());
            }
            //对密码进行判断匹配
            @Override
            public boolean matches(CharSequence charSequence, String s) {
                String encode = DigestUtils.md5DigestAsHex(charSequence.toString().getBytes());
                boolean res = s.equals( encode );
                return res;
            }
        } );

    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
        http.requestMatchers()
                .antMatchers("/oauth/**","/login","/login-error")
                .and()
                .authorizeRequests()
                .antMatchers("/oauth/**").authenticated()
                .and()
                .formLogin().loginPage( "/login" ).failureUrl( "/login-error" );
    }


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

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new PasswordEncoder() {
            @Override
            public String encode(CharSequence charSequence) {
                return charSequence.toString();
            }

            @Override
            public boolean matches(CharSequence charSequence, String s) {
                return Objects.equals(charSequence.toString(),s);
            }
        };
    }


}

验证

密码授权模式

[ 密码模式需要参数：username , password , grant_type , client_id , client_secret ]

请求token

curl -X POST -d "username=admin&password=123456&grant_type=password&client_id=dev&client_secret=dev" http://localhost:8080/oauth/token

返回

{
	"access_token": "d94ec0aa-47ee-4578-b4a0-8cf47f0e8639",
	"token_type": "bearer",
	"refresh_token": "23503bc7-4494-4795-a047-98db75053374",
	"expires_in": 3475,
	"scope": "app"
}

不携带token访问资源，

curl http://localhost:8080/hi?name=zhangsan

返回提示未授权

{
	"error": "unauthorized",
	"error_description": "Full authentication is required to access this resource"
}

携带token访问资源

curl http://localhost:8080/hi?name=zhangsan&access_token=164471f7-6fc6-4890-b5d2-eb43bda3328a

返回正确

hi , zhangsan

刷新token

curl  -X POST -d 'grant_type=refresh_token&refresh_token=23503bc7-4494-4795-a047-98db75053374&client_id=dev&client_secret=dev' http://localhost:8080/oauth/token

返回

{
    "access_token": "ef53eb01-eb9b-46d8-bd58-7a0f9f44e30b",
    "token_type": "bearer",
    "refresh_token": "23503bc7-4494-4795-a047-98db75053374",
    "expires_in": 3599,
    "scope": "app"
}

客户端授权模式

[ 客户端模式需要参数：grant_type , client_id , client_secret ]

请求token

curl -X POST -d "grant_type=client_credentials&client_id=dev&client_secret=dev" http://localhost:8080/oauth/token

返回

{
	"access_token": "a7be47b3-9dc8-473e-967a-c7267682dc66",
	"token_type": "bearer",
	"expires_in": 3564,
	"scope": "app"
}

授权码模式

获取code

浏览器中访问如下地址：

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

跳转到登录页面，输入账号和密码进行认证：

认证后会跳转到授权确认页面（oauth_client_details 表中 “autoapprove” 字段设置为true 时，不会出授权确认页面）：

确认后，会跳转到百度，并且地址栏中会带上我们想得到的code参数：

通过code换token

curl -X POST -d "grant_type=authorization_code&code=qS03iu&client_id=dev&client_secret=dev&redirect_uri=http://www.baidu.com" http://localhost:8080/oauth/token

返回

{
    "access_token": "90a246fa-a9ee-4117-8401-ca9c869c5be9",
    "token_type": "bearer",
    "refresh_token": "23503bc7-4494-4795-a047-98db75053374",
    "expires_in": 3319,
    "scope": "app"
}
