crossref CN lookups

lookup_curl.sh

#!/bin/bash

curl -SLH "Accept: text/bibliography; style=apa" http://dx.doi.org/$1

lookup_habanero.py

#!/usr/bin/env python

from __future__ import print_function
from habanero import cn
import sys

doi_name = 'doi:' + sys.argv[1]
print(cn.content_negotiation(ids=doi_name, format="text", style="apa"))

lookup_requests.py

#!/usr/bin/env python

from __future__ import print_function
import requests
import sys

headers = {'Accept': 'text/bibliography; style=apa', 'Accept-Encoding': 'utf-8'}
response = requests.get('http://dx.doi.org/' + sys.argv[1], headers=headers)
print(response.text.encode(response.encoding).decode('utf-8'))

Using habanero to do content negotiation can result in mangled character encoding.

For example, looking up doi:10.1093/bioinformatics/btp324 results in different output from habanero.cn vs a standard curl:

lookup_curl.sh:

Li, H., & Durbin, R. (2009). Fast and accurate short read alignment with Burrows-Wheeler transform. Bioinformatics, 25(14), 1754–1760. doi:10.1093/bioinformatics/btp324

lookup_habanero.py:

Li, H., & Durbin, R. (2009). Fast and accurate short read alignment with Burrows-Wheeler transform. Bioinformatics, 25(14), 1754�1760. doi:10.1093/bioinformatics/btp324

Requests marks the response encoding as ISO-8859-1. While cn returns the response text, it does not pass along the encoding.
