Identity Server - 名为Expires的Oauth2 userinfo / Missing Field

Question

WSO2身份服务器中是否有配置选项为范围定义一组自定义声明值＆＃34; openid＆＃34;并在几秒钟内添加当前令牌到期。这个名为＆＃34;的计数器到期了＃34;在进入过期状态之前，可能有助于跟踪和更新老化令牌。我目前看到以下值从＆＃34; userinfo＆＃34;查询：

A = LOAD '/user/uszanr8/pigtest/file1' using PigStorage(',')  AS(l1:int,l2:chararray,l3:int); 
B = LOAD '/user/uszanr8/pigtest/file2'  using PigStorage(',') AS(r1:int,r2:chararray,r3:int,r4:chararray); 
C = FILTER B BY r4 == 'Y';
D = JOIN A BY l1  LEFT OUTER, B BY r1 ;
E = FILTER D BY r1 is NULL;
F = FOREACH E GENERATE l1,l2,l3;
DUMP F;
