Re: [islandora] MicroServices

[Steve Sonnenberg]

Hi Team,

I've been trying to get MicroServices to work on the Islandora_VM 12.1 using the sample plugin, but am running into a simple authorization failure.

The islandora_microservices.cfg file has a username/password fedoraAdmin,password are these the wrong credentials?

My islandora_microservices.log file shows:

Hi Steve

Assuming you've not changed the default Fedora credentials on the VM then the username will be fedoraAdmin and the password will be islandora. To confirm this (or to change these to something a little more secure) you can view/edit the the file /usr/local/fedora/server/config/fedora-users.xml

Thanks Richard, I no longer get the 401 error.
During an ingest of a simple image, I get the following:

When I enter that URL in my browser I get back a valid objectProfile (in XML)

Is there additional logging that I can enable on the server side?

Thanks

DEBUG is the highest level of logging you can set but you can put your own logging statements into the plugin. Adding logging.debug() lines to output more variables can help a lot when you're trying to work out what's going on.

One thing you might want to try is changing the url to /fedora/objects/islandora:365?format=xml if you are just after the XML.

Has anyone managed to resolve this issue.  I am having the same problems setting up microservices.
