版本:
Spring Boot 1.4.3、Spring Security OAuth2 2.0.12
OAuth2.0的开源 Server / Client 实现可以参考这里： https://oauth.net/code/，这里采用Spring Security OAuth2实现四种授权模式中最常用的：Authorization Code Grant。
具体可以看OAuth2.0标准的定义： https://tools.ietf.org/html/rfc6749#section-4.1。
这里首先只为演示 OAuth2.0 的整个过程，做最小实现！
Spring Security OAuth2默认提供的四个URL：
- /oauth/authorize ： 授权AuthorizationEndpoint
- /oauth/token ： 令牌TokenEndpoint
- /oauth/check_token ： 令牌校验CheckTokenEndpoint
- /oauth/confirm_access ： 授权页面WhitelabelApprovalEndpoint
- /oauth/error ： 错误页面WhitelabelErrorEndpoint

（1）授权请求(Get)
URL： http://localhost:8080/oauth/authorize?client_id=oauth_client&scope=read&response_type=code&state=rensanning&redirect_uri=http://default-oauth-callback.com
由于对/oauth/authorize开启了HTTP Basic认证，所以需要输入密码:
输入正确用户名密码（user/123）后显示授权页：
选择Approve点击Authorize按钮后，自动跳转到 http://default-oauth-callback.com?code=sdb6vF&state=rensanning
URL中的code参数值即为授权码，该值是一个6位英数字的随机数，具体可以看源码：org.springframework.security.oauth2.common.util.RandomValueStringGenerator.generate()
！！授权码10分钟过期目前还没有实现！！ https://github.com/spring-projects/spring-security-oauth/issues/725
（2）获得令牌(Post)
URL： http://localhost:8080/oauth/token?grant_type=authorization_code&redirect_uri=http://default-oauth-callback.com&code=sdb6vF
【/oauth/token】默认采用的是HTTP Basic Auth（org.springframework.security.web.authentication.www.BasicAuthenticationFilter），所以需要在HTTP的header里提供clientId和clientSecret的Base64值。具体可以执行Test.java获取。
Authorization: Basic b2F1dGhfY2xpZW50Om9hdXRoX2NsaWVudF9zZWNyZXQ=
通过以下设置，可以通过参数的形式传递clientId和clientSecret的值。比如：http://localhost:8080/oauth/token?grant_type=authorization_code&redirect_uri=http://default-oauth-callback.com&code=sdb6vF&client_id=oauth_client&client_secret=oauth_client_secret
@Configuration
@EnableAuthorizationServer
protected static class OAuth2Config extends AuthorizationServerConfigurerAdapter {
@Override
public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
oauthServer.allowFormAuthenticationForClients();
}
}
返回令牌信息
引用
{
"access_token": "1cc5ffbd-faac-4d20-afd9-b8531acd248e",
"token_type": "bearer",
"refresh_token": "5b319fed-5600-4ea2-8c4f-61f6e3ea6e41",
"expires_in": 1631,
"scope": "read"
}
"access_token": "1cc5ffbd-faac-4d20-afd9-b8531acd248e",
"token_type": "bearer",
"refresh_token": "5b319fed-5600-4ea2-8c4f-61f6e3ea6e41",
"expires_in": 1631,
"scope": "read"
}
生成的令牌是一个UUID，具体可以看源码：org.springframework.security.oauth2.provider.token.DefaultTokenServices.createAccessToken()
（4）访问API(Get)
直接访问API返回401。URL： http://localhost:8080/api/get
通过access_token参数访问。URL： http://localhost:8080/api/get?access_token=1cc5ffbd-faac-4d20-afd9-b8531acd248e
通过http header参数访问。URL： http://localhost:8080/api/get
Authorization: Bearer 1cc5ffbd-faac-4d20-afd9-b8531acd248e
*** @EnableResourceServer 自动增加OAuth2AuthenticationProcessingFilter过滤器
*** ！！SpringBoot1.5 @EnableResourceServer和@EnableWebSecurity配置的HttpSecurity有先后顺序的问题，需要特殊设置！！参考：
https://github.com/spring-projects/spring-security-oauth/issues/993#issuecomment-284430752
https://stackoverflow.com/questions/29893602/spring-security-form-logging-and-outh2-in-same-app
（5）刷新令牌(Post)
URL： http://localhost:8080/oauth/token?grant_type=refresh_token&refresh_token=5b319fed-5600-4ea2-8c4f-61f6e3ea6e41
Authorization: Basic b2F1dGhfY2xpZW50Om9hdXRoX2NsaWVudF9zZWNyZXQ=
返回新的access_token：
引用
{
"access_token": "3cbe70fc-753f-44ff-9bb4-0ba6bc3c9aab",
"token_type": "bearer",
"refresh_token": "5b319fed-5600-4ea2-8c4f-61f6e3ea6e41",
"expires_in": 1800,
"scope": "read"
}
"access_token": "3cbe70fc-753f-44ff-9bb4-0ba6bc3c9aab",
"token_type": "bearer",
"refresh_token": "5b319fed-5600-4ea2-8c4f-61f6e3ea6e41",
"expires_in": 1800,
"scope": "read"
}
旧的Token就不能再用了：
通过新的Token访问API：
同理，可以测试scope为write的权限！
