Keycloak：使查询字符串参数在标记 FreeMarker 模板中可用

Question

Context: using https://www.keycloak.org/ as an authentication provider.

I have a use case where I need to render a block of HTML depending on the value of a query string param in the login page. The value will be coming from the login URL similar to this:

http://localhost:8080/auth/realms/default/protocol/openid-connect/auth?...&customvar=1

I would like to have customvar available in the login.ftl to accomplish my objective. So far I have tried to retrieve the baseUrl from the client bean, but it's not available, the app crashes when I attempt to access baseUrl. I have also attempted to access the request url in the ${url} , but it's not available either.

Thanks in advance for any help.

Answer 1

尝试 href="${client.baseUrl}" 它应该返回一个客户端 baseUrl。
