keycloak设置master登录用户

keycloak 管理界面

keycloak 获取用户token 

• 创建我们自己的域
  

• 添加域的用户

  

• 设置密码

•  创建client（普通用户登录 设置public）

• 查看openid配置详情

接口：http://localhost:8080/auth/realms/{创建的realm名字}/.well-known/openid-configuration
示例：http://localhost:8080/auth/realms/keycloak-manage-user/.well-known/openid-configuration

• confidential client 设置 

public confidential 区别：
public 就是简单的账号密码登录
confidential 需要算法支持
从配置中可以看到支持5种： 

     "private_key_jwt","client_secret_basic","client_secret_post","tls_client_auth","client_secret_jwt"

• client_secret 方式获取用户token

 

curl --location --request POST 'http://localhost:8080/auth/realms/keycloak-manage-user/protocol/openid-connect/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'grant_type=client_credentials' \
--data-urlencode 'client_id=user-token' \
--data-urlencode 'client_secret=40bf9908-94e1-4571-8ad3-10940e21ee9f' \
--data-urlencode 'username=test' \
--data-urlencode 'password=123456'

注意grant_type=client_credentials参数的修改

• client 认证 "client_secret_post " 获取client token

 

这里新建了realm和client方便区分

curl --location --request POST 'http://localhost:8080/auth/realms/openbanking/protocol/openid-connect/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'client_id=client1-mtls-PS256-PS256' \
--data-urlencode 'client_secret=63795b52-65ec-468c-a7b9-4b73817bdfc9' \
--data-urlencode 'grant_type=client_credentials'

•  client 认证 “client_secret_basic” 获取client token

 

 

curl --location --request POST 'http://localhost:8080/auth/realms/openbanking/protocol/openid-connect/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--header 'Authorization: Basic Y2xpZW50MS1tdGxzLVBTMjU2LVBTMjU2OjYzNzk1YjUyLTY1ZWMtNDY4Yy1hN2I5LTRiNzM4MTdiZGZjOQ==' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'grant_type=client_credentials' \
--data-urlencode 'client_id=client1-mtls-PS256-PS256' \
--data-urlencode 'scope=accounts'

 Base64.getEncoder().encodeToString((id + “:” + secret).getBytes());

• client 认证 “private_key_jwt” 获取client token

         RSAKey privateKey = new RSAKeyGenerator(2048).algorithm(JWSAlgorithm.PS256).keyUse(KeyUse.SIGNATURE).keyID("client-PS256").generate();RSAKey publicKey = privateKey.toPublicJWK();
