Keycloak:REST API调用，用于通过管理员用户名和密码获取用户的访问令牌 [英] Keycloak :REST API call to get access token of a user through admin username and password

问题描述

我有一个需要获取用户访问令牌的要求.

I have a requirement where I need to get an access token of a user.

我知道管理员的用户名和密码，因此可以获得管理员的访问令牌.

I am aware of the admin username and password and hence can get the access token of the admin.

是否有任何其他API可以为使用上述数据的用户提供访问令牌?

Is there any rest API that can provide me access token a user using the above data?

推荐答案

有两种获取访问令牌的方法.一种带有Rest客户端(keycloak Rest API)，另一种则通过java keycloak-admin-client库.

There are two ways to get access token. One with Rest client (keycloak Rest API) and other through java keycloak-admin-client library.

1. Keycloak Rest API:

URI: http://keycloak:8080/auth/realms/myrealm/protocol/openid-connect/token
Type: POST
Content-Type: application/x-www-form-urlencoded
grant_type:password
username:user
password:user_password
client_id:client_id
secret_id:client_secret

2. Keycloak admin client (JAVA)

Keycloak instance = Keycloak.getInstance("http://keycloak:8080/auth", "myrealm", "user", "user_password","client_id", "client_secret");                                                                                                      
TokenManager tokenmanager = instance.tokenManager();
String accessToken = tokenmanager.getAccessTokenString();
