微博 oauth2.0 授权时间自动刷新不生效是怎么回事

[liuhaotian]

微博open API oauth2.0，测试级别。用测试用户登录，第一次授权结束之后不断登录但是授权更新时间不会刷新，expire在不断减少。官方帮助里面这么写：

access_token自动延续方案
如果用户在授权有效期内重新打开授权页授权（如果此时用户有微博登录状态，这个页面将一闪而过），那么新浪会为开发者自动延长access_token的生命周期，请开发者维护新授权后得access_token值。

但是我实际操作里并没有延长，access_token的生命周期不断减少，不知道这是什么原因。

我自己这边测试结果是立即重新登录不会刷新
超过一段时间后会刷新(比如一天
从11号到19号的记录, 每天10点登录
