I don't want boring you with this problem but I implemented the definitive
solution keeping zeppenlin authorization as is. I think is the more clean
solution.
Use apache proxy to overcome CORS problems
I did proceed in this way:
Zeppelin: modify zeppelin-site.xml change property zeppelin.server.context.path
from "/" to "/zeppelin"
Apache2 in the same host (in my case 192.168.56.107) where your app lives:
enable module proxy proxy_http
add the following lines to , ie. http-vhost.conf
ProxyPass /zeppelin http://192.168.56.105:9090/zeppelin
timeout=600
ProxyPassReverse /zeppelin http://192.168.56.105:9090/zeppelin
timeout=600
Your app: call zeppelin rest api using Apache2 host,
ie. http://192.168.56.107/zeppelin/api/login ,
http://192.168.56.107/zeppelin/api/notebook etc.
STOP.
if you would include paragraph link into any iframes of your app rebembers to
proxy websocket too
Best regards,
Alessandro
