Compatibility with HTTPS everywhere config for EPrints 3.4.1+

[drn05r]

EPrints 3.4.1+ allows for simplified configuration of HTTPS only (where all HTTP requests get redirected to HTTPS). See:

https://wiki.eprints.org/w/Simplified_HTTPS_Configuration

This requires $c->{host} to be unset and only $c->{securehost} to be set. This is a problem for the below line: *

DataCiteDoi/cfg/cfg.d/z_datacitedoi.pl

Line 35 in 1e5b538

$c->{datacitedoi}{repoid} = $c->{host};

If you install the DataCiteDOI plugin and you have used the simplified HTTPS configuration method for HTTPS only. This will cause an error and create the wrong DOIs, as they will not include the hostname of the EPrints repository. The following line after the line reference above will fix this issue:

$c->{datacitedoi}{repoid} ||= $c->{securehost};
