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);

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"
}
