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。
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 parameters = new LinkedHashMap(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(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, 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(OAuth2Authentication authentication, OAuth2RefreshToken refreshToken) {
DefaultOAuth2AccessToken token = new DefaultOAuth2AccessToken(uuid);
token.setExpiration(Date)
token.setRefreshToken(refreshToken);
token.setScope(authentication.getOAuth2Request().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 additionalInfo = new HashMap<>(8);
PigxUser pigxUser = (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。
