问题
I started with Using OpenID/Keycloak with Superset and did everything as explained. However, it is an old post, and not everything worked. I'm also trying to implement a custom security manager by installing it as a FAB add-on, so as to implement it in my application without having to edit the existing superset code.
I'm running KeyCloak 4.8.1.Final and Apache SuperSet v 0.28.1
As explained in the post, SuperSet does not play nicely with KeyCloak out of the box because it uses OpenID 2.0 and not OpenID Connect, which is what KeyCloak provides.
The first difference is that after pull request 4565 was merged, you can no longer do:
from flask_appbuilder.security.sqla.manager import SecurityManager
Instead, you now have to use: (as per the UPDATING.md file)
from superset.security import SupersetSecurityManager
In the above mentioned post, the poster shows how to create the manager and view files separately, but don't say where to put it. I placed both the manager and view classes in the same file, named manager.py, and placed it in the FAB add-on structure.
from flask_appbuilder.security.manager import AUTH_OID
from superset.security import SupersetSecurityManager
from flask_oidc import OpenIDConnect
from flask_appbuilder.security.views import AuthOIDView
from flask_login import login_user
from urllib.parse import quote
from flask_appbuilder.views import ModelView, SimpleFormView, expose
import logging
class OIDCSecurityManager(SupersetSecurityManager):
def __init__(self,appbuilder):
super(OIDCSecurityManager, self).__init__(appbuilder)
if self.auth_type == AUTH_OID:
self.oid = OpenIDConnect(self.appbuilder.get_app)
self.authoidview = AuthOIDCView
CUSTOM_SECURITY_MANAGER = OIDCSecurityManager
class AuthOIDCView(AuthOIDView):
@expose('/login/', methods=['GET', 'POST'])
def login(self, flag=True):
sm = self.appbuilder.sm
oidc = sm.oid
@self.appbuilder.sm.oid.require_login
def handle_login():
user = sm.auth_user_oid(oidc.user_getfield('email'))
if user is None:
info = oidc.user_getinfo(['preferred_username', 'given_name', 'family_name', 'email'])
user = sm.add_user(info.get('preferred_username'), info.get('given_name'), info.get('family_name'), info.get('email'), sm.find_role('Gamma'))
login_user(user, remember=False)
return redirect(self.appbuilder.get_url_for_index)
return handle_login()
@expose('/logout/', methods=['GET', 'POST'])
def logout(self):
oidc = self.appbuilder.sm.oid
oidc.logout()
super(AuthOIDCView, self).logout()
redirect_url = request.url_root.strip('/') + self.appbuilder.get_url_for_login
return redirect(oidc.client_secrets.get('issuer') + '/protocol/openid-connect/logout?redirect_uri=' + quote(redirect_url))
I have the CUSTOM_SECURITY_MANAGER variable set in this file and not in superset_config.py. This is because it didn't work when it was there, it didn't load the custom security manager. I moved the variable there after reading Decorator for SecurityManager in flask appbuilder for superest.
My client_secret.json file looks as follows:
{
"web": {
"realm_public_key": "<PUBLIC_KEY>",
"issuer": "https://<DOMAIN>/auth/realms/demo",
"auth_uri": "https://<DOMAIN>/auth/realms/demo/protocol/openid-connect/auth",
"client_id": "local",
"client_secret": "<CLIENT_SECRET>",
"redirect_urls": [
"http://localhost:8001/*"
],
"userinfo_uri": "https://<DOMAIN>/auth/realms/demo/protocol/openid-connect/userinfo",
"token_uri": "https://<DOMAIN>/auth/realms/demo/protocol/openid-connect/token",
"token_introspection_uri": "https://<DOMAIN>/auth/realms/demo/protocol/openid-connect/token/introspect"
}
}
realm_public_key: I got this key at Realm Settings > Keys > Active and then in the table, in the "RS256" row.client_id: local (the client I use for local testing)client_secret: I got this at Clients > local (from the table) > Credentials > Secret
All the url/uri values are adjusted from the first mentioned post I used to set it all up. The <DOMAIN> is an AWS CloudFront default domain, since I'm running KeyCloak on EC2 and don't want to go through the trouble to setup a custom HTTPS domain for simply getting it up and running.
Then, finally, part of my superset_config.py file looks like this:
ADDON_MANAGERS = ['fab_addon_keycloak.manager.OIDCSecurityManager']
AUTH_TYPE = AUTH_OID
OIDC_CLIENT_SECRETS = '/usr/local/lib/python3.6/site-packages/fab_addon_keycloak/fab_addon_keycloak/client_secret.json'
OIDC_ID_TOKEN_COOKIE_SECURE = False
OIDC_REQUIRE_VERIFIED_EMAIL = False
AUTH_USER_REGISTRATION = True
AUTH_USER_REGISTRATION_ROLE = 'Gamma'
OPENID_PROVIDERS = [{
'name': 'KeyCloak',
'url': 'https://<DOMAIN>/auth/realms/demo/account'
}]
In the original post, the OPENID_PROVIDERS environment variable is not mentioned, so I'm not really sure what to put in here for the URL. I put that one since that's the URL you'll hit to login to the client console on KeyCloak.
When I run SuperSet I don't get any errors. I can see that the custom security manager loads. When I navigate to the login screen, I have to choose my provider, I don't get a login form. I choose KeyCloak, since there's obviously nothing else, and click Login. When I click Login I can see that something loads in the address bar of the browser, but nothing happens. It's my understanding that I'm supposed to be redirected to the KeyCloak login form, and then back to my application upon successful login, but nothing happens. Am I missing something somewhere?
Edit
So after some more digging, it seems like my custom view class loads, however the methods in the class do not override the default behavior. Not sure why this is happening or how to fix it.
回答1:
I ended up figuring it out myself.
The solution I ended up with does not make use of a FAB add-on, but you also don't have to edit existing code/files.
I've renamed the manager.py file to security.py, and it now looks like this:
from flask import redirect, request
from flask_appbuilder.security.manager import AUTH_OID
from superset.security import SupersetSecurityManager
from flask_oidc import OpenIDConnect
from flask_appbuilder.security.views import AuthOIDView
from flask_login import login_user
from urllib.parse import quote
from flask_appbuilder.views import ModelView, SimpleFormView, expose
import logging
class AuthOIDCView(AuthOIDView):
@expose('/login/', methods=['GET', 'POST'])
def login(self, flag=True):
sm = self.appbuilder.sm
oidc = sm.oid
@self.appbuilder.sm.oid.require_login
def handle_login():
user = sm.auth_user_oid(oidc.user_getfield('email'))
if user is None:
info = oidc.user_getinfo(['preferred_username', 'given_name', 'family_name', 'email'])
user = sm.add_user(info.get('preferred_username'), info.get('given_name'), info.get('family_name'), info.get('email'), sm.find_role('Gamma'))
login_user(user, remember=False)
return redirect(self.appbuilder.get_url_for_index)
return handle_login()
@expose('/logout/', methods=['GET', 'POST'])
def logout(self):
oidc = self.appbuilder.sm.oid
oidc.logout()
super(AuthOIDCView, self).logout()
redirect_url = request.url_root.strip('/') + self.appbuilder.get_url_for_login
return redirect(oidc.client_secrets.get('issuer') + '/protocol/openid-connect/logout?redirect_uri=' + quote(redirect_url))
class OIDCSecurityManager(SupersetSecurityManager):
authoidview = AuthOIDCView
def __init__(self,appbuilder):
super(OIDCSecurityManager, self).__init__(appbuilder)
if self.auth_type == AUTH_OID:
self.oid = OpenIDConnect(self.appbuilder.get_app)
I place the security.py file next to my superset_config_py file.
The JSON configuration file stays unchanged.
Then I've changed the superset_config.py file to include the following lines:
from security import OIDCSecurityManager
AUTH_TYPE = AUTH_OID
OIDC_CLIENT_SECRETS = <path_to_configuration_file>
OIDC_ID_TOKEN_COOKIE_SECURE = False
OIDC_REQUIRE_VERIFIED_EMAIL = False
AUTH_USER_REGISTRATION = True
AUTH_USER_REGISTRATION_ROLE = 'Gamma'
CUSTOM_SECURITY_MANAGER = OIDCSecurityManager
That's it.
Now when I navigate to my site, it automatically goes to the KeyCloak login screen, and upon successful sign in I am redirected back to my application.
