如何强制客户端刷新认知令牌 [英] How can I force a cognito token refresh from the client

问题描述

我正在使用aws放大，我知道令牌会在需要时自动刷新，并且在后台完成.

I am using aws amplify and I know that the tokens get automatically refreshed when needed and that that is done behind the scenes.

我需要做的是通过Lambda后端进程在cognito用户池中的用户上更改自定义属性.我可以做到，并且正在运行.但是，Web客户端用户从未看到过这个新的自定义属性，我在想，他们看到该令牌的唯一方法是令牌是否被刷新，因为该值存储在JWT令牌中.

What I need to do is change a custom attribute on the user in the cognito user pool via a Lambda backend process. This I can do, and it is working. However, the web client user never sees this new custom attribute and I am thinking the only way they can see it is if the token gets refreshed since the value is stored within the JWT token.

推荐答案

未公开，但是您可以在用户上使用 refreshSession 方法.您对currentAuthenticatedUser和currentSession的下一次调用将更新配置文件属性(和组)

Undocumented, but you can use the refreshSession method on the User. Your next call to currentAuthenticatedUser and currentSession will have updated profile attributes (and groups)

User = Auth.currentAuthenticatedUser()
Session =  Auth.currentSession()

User.refreshSession(Session.refreshToken))
