Request to dx.doi.org doesn't finish

[c-langlet]

There seems to be a bug when querying the dx.doi.org server to ensure DOI existence throught the requests API.

I managed to solve the bug by changing url definition in pdf2doi.finders.validate_doi_web from (line 48):
url = "http://dx.doi.org/" + doi
to
url = "https://dx.doi.org/" + doi

My configuration:

python 3.10
pdf2doi 1.6
requests 2.25.1

Thanks for the useful module !

Thanks for letting us know. It might be some change on the doi.org website. Which error message do you get?

[c-langlet]

I don't get any, the request never ends

Thanks, I'll change the url as you suggested in the next version

I implemented this change in version 1.7 (just published), please re-open the issue if the problem persists.
