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

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(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;
}

// 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

additionalinfo.put("user_id", pigxuser.getid());

((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。
