Ignore SSL errors in prepareEsriBasemapsForOfflineUse.py

Question asked by aug_aug on May 4, 2018
Latest reply on May 10, 2018 by aug_aug

I'm trying to run this script against our federated Portal to add basemaps for offline. The only way I can seem to access our Portal (I've tested in jupyter notebook) without SSL errors thru python is if I include the "verify_cert=False" parameter. 

 

Can someone please show me how to modify the "prepareEsriBasemapsForOfflineUse.py" python script such that the certificate errors are ignored? Like where exactly I should insert the "verify_cert=False" parameter below (python noob here). I seem to recall not having this problem on one of our older servers with this script, maybe one that wasn't https...

 

Thanks in advance!

 

IOError: [Errno socket error] [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661)

# python addOfflineBasemaps.py -u <destinationPortal> -o <portalAdmin>
#                              -s <portalPassword> -f <destFolder>
