@adaniela a essayé d’utiliser l’api dans une web app rails sans succès pour le moment. Ci-dessous l'erreur que j'ai eu: "rails aborted! OpenURI::HTTPError: 403 Please identify your user agent, see https://meta.wikimedia.org/wiki/User-Agent_policy"

Entête pour la requête GET : User-Agent: EndangeredSpeciesIdentifier/0.1 (contact@okfnfr; http://cites.okfn.fr/en/home/)

itly314 commented 5 years ago

Example of how to query the Wikidata API from Python using the `requests` library

See docs on the requests library here

import requests

# Wikidata SPARQL endpoint
url = 'https://query.wikidata.org/sparql'

# build the SPARQL query string
sparql_string = '\
SELECT distinct ?taxonRank ?idCITES  ?nomSc \
WHERE { \
  ?item wdt:P2040 ?idCITES . \
  ?item wdt:P225 ?nomSc . \
  ?item wdt:P105 ?taxonRank \
  OPTIONAL { ?item wdt:P18 ?image . } \
  SERVICE wikibase:label { bd:serviceParam wikibase:language "fr" } \
  } \
LIMIT 20  \
'

# set custom header required by Wikidata service ; pass them in as a dict
# (optional? - the GET call seems to work from Python without this)
header ={'User-Agent':'EndangeredSpeciesIdentifier/0.1 (contact@okfnfr; http://cites.okfn.fr/en/home/)'}

# specify url parameters ; pass in as a dict
params = {'format':'json','query':sparql_string}

# make the HTTP GET call
r = requests.get(url, params=params, headers=header)

# examine the json returned
print( r.json() )

# display the results without the query metadata
print( r.json()['results']['bindings'] )

# display only the first result
print( r.json()['results']['bindings'][0] )
