问题描述

如果用户的access_token过期并且用户希望继续登录，则需要使用户继续在系统中登录.

I need to make the user keep login in the system if the user's access_token get expired and user want to keep login. How can I get newly updated access_token with the use of refresh_token on Keycloak?

我正在将 vertx-auth 用于与 vert.x 上的https://www.keycloak.org"rel =" noreferrer>密钥斗篷.是否可以使用 vertx-auth 或

I am using vertx-auth for the auth implementation with Keycloak on vert.x. Is it possible to refresh access_token with vertx-auth or Keycloak's REST API itself? Or what will be another implementation of this?

推荐答案

keycloak具有用于使用refresh_token创建access_token的REST API.这是一个POST endpoint with application/x-www-form-urlencoded

keycloak has REST API for creating an access_token using refresh_token. It is a POST endpoint with application/x-www-form-urlencoded

这是它的外观:

Method: POST
URL: https://keycloak.example.com/auth/realms/myrealm/protocol/openid-connect/token
Body type: x-www-form-urlencoded
Form fields:    
client_id : <my-client-name>
grant_type : refresh_token
refresh_token: <my-refresh-token>

这将使用刷新令牌为您提供新的访问令牌.

This will give you new access token using refresh token.

注意::如果您的刷新令牌已过期，则会引发400个异常，您可以再次使用户登录.

NOTE: if your refresh token is expired it will throw 400 exception in that you can make user login again.

在Postman中查看示例，您可以使用它开发相应的API.

Check out a sample in Postman, you can develop and corresponding API using this.
