Spring Security OAuth 个性化token

个性化Token 目的

默认通过调用 /oauth/token 返回的报文格式包含以下参数

{

"access_token": "e6669cdf-b6cd-43fe-af5c-f91a65041382",

"token_type": "bearer",

"refresh_token": "da91294d-446c-4a89-bdcf-88aee15a75e8",

"expires_in": 43199,

"scope": "server"

}

并没包含用户的业务信息比如用户信息、租户信息等。

扩展生成包含业务信息（如下）,避免系统多次调用，直接可以通过认证接口获取到用户信息等，大大提高系统性能

{

"access_token":"a6f3b6d6-93e6-4eb8-a97d-3ae72240a7b0",

"token_type":"bearer",

"refresh_token":"710ab162-a482-41cd-8bad-26456af38e4f",

"expires_in":42396,

"scope":"server",

"tenant_id":1,

"license":"made by pigx",

"dept_id":1,

"user_id":1,

"username":"admin"

}

密码模式生成Token 源码解析

​ 主页参考红框部分

ResourceOwnerPasswordTokenGranter （密码模式）根据用户的请求信息，进行认证得到当前用户上下文信息

protected OAuth2Authentication getOAuth2Authentication(ClientDetails client, TokenRequest tokenRequest) {

Map<String, String> parameters = new LinkedHashMap<String, String>(tokenRequest.getRequestParameters());

String username = parameters.get("username");

String password = parameters.get("password");

// Protect from downstream leaks of password

parameters.remove("password");

Authentication userAuth = new UsernamePasswordAuthenticationToken(username, password);

((AbstractAuthenticationToken) userAuth).setDetails(parameters);

userAuth = authenticationManager.authenticate(www.yinxionghui1.com/ userAuth);

OAuth2Request storedOAuth2Request = getRequestFactory().createOAuth2Request(client, tokenRequest);

return new OAuth2Authentication(storedOAuth2Request, userAuth);

}

然后调用AbstractTokenGranter.getAccessToken() 获取OAuth2AccessToken

protected OAuth2AccessToken getAccessToken(ClientDetails client, TokenRequest tokenRequest) {

return tokenServices.createAccessToken(getOAuth2Authentication(client, tokenRequest));

}

默认使用DefaultTokenServices来获取token

public OAuth2AccessToken createAccessToken(OAuth2Authentication authentication) throws AuthenticationException {

... 一系列判断 ，合法性、是否过期等判断

OAuth2AccessToken accessToken = createAccessToken(authentication, refreshToken);

tokenStore.storeAccessToken(accessToken,www.dasheng178.com authentication);

// In case it was modified

refreshToken = accessToken.getRefreshToken();

if (refreshToken != null) {

tokenStore.storeRefreshToken(refreshToken, authentication);

}

return accessToken;

}

createAccessToken 核心逻辑

// 默认刷新token 的有效期

private int refreshTokenValiditySeconds = 60 * 60 * 24 * 30; // default 30 days.

// 默认token 的有效期

private int accessTokenValiditySeconds = 60 * 60 * 12; // default 12 hours.

private OAuth2AccessToken createAccessToken(www.michenggw.com OAuth2Authentication authentication, OAuth2RefreshToken refreshToken) {

DefaultOAuth2AccessToken token = new DefaultOAuth2AccessToken(uuid);

token.setExpiration(Date)

token.setRefreshToken(refreshToken);

token.setScope(authentication.getOAuth2Request(www.tianshengyuLe1.cn).getScope());

return accessTokenEnhancer != null ? accessTokenEnhancer.enhance(token, authentication) : token;

}

如上代码，在拼装好token对象后会调用认证服务器配置TokenEnhancer( 增强器) 来对默认的token进行增强。

TokenEnhancer.enhance 通过上下文中的用户信息来个性化Token

public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) {

final Map<String, Object> additionalInfo = new HashMap<www.zhongxinyul2.com>(8);

PigxUser pigxUser =www.yongshi123.cn (PigxUser) authentication.getUserAuthentication().getPrincipal();

additionalInfo.put("user_id", pigxUser.getId());

additionalInfo.put("username", pigxUser.getUsername());

additionalInfo.put("dept_id", pigxUser.getDeptId());

additionalInfo.put("tenant_id", pigxUser.getTenantId());

additionalInfo.put("license", SecurityConstants.PIGX_LICENSE);

((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(additionalInfo);

return accessToken;

}

基于pig 看下最终的实现效果

Pig 基于Spring Cloud、oAuth2.0开发基于Vue前后分离的开发平台，支持账号、短信、SSO等多种登录，提供配套视频开发教程。
