When trying to import a publication by DOI lookup, I get an error "HTTP error: 400 when trying to contact crossref.org for XML input"
Found a solution online: "In the Biblio file, ...site/all/modules/biblio/modules/crossref/biblio.crossref.client.php, in the function called fetch, you have to make the following change:
FROM: $request_options = array('method' => 'POST');
TO: $request_options = array('method' => 'GET');
It should have been GET in the first place, I suppose; but it seems that POST had been working, as well.
The problem is that the crossref.org server is now throwing a Java exception when you present it with a POST request at this URL, thus producing the 400 server error."
Is there a way to get this fixed with our biblio module?
