[Résolu]-[Python] - urllib.request.urlopen en erreur

[Ernest]

Bonjour,

Je suis en train d' adapter pour libreoffice,un script python fonctionnel avec mon éditeur. Avec apso je me heurte à une erreur de certificat. Voici le début du script python:

Code : Tout sélectionner

import urllib.request
url = "https://www.boursorama.com/cours/1rPAF/"
rqt = urllib.request.Request(url)
rslt = urllib.request.urlopen(rqt)

Alors que cette syntaxe fonctionne sans problème avec mon éditeur python, sous libreoffice/apso, j' obtiens le message d' erreur suivant:

Code : Tout sélectionner

Traceback (most recent call last):

Pourriez-vous m' expliquer ce problème de certificat ?
Par avance merci.
Cordialement

Bonsoir,
Si cela peut aider des utilisateurs, voici la solution que j' ai mis en place.

Code : Tout sélectionner

import urllib.request
import ssl
url = "https://www.boursorama.com/cours/1rPAF/"
rqt = urllib.request.Request(url)
#Passer outre la vérification de certificat
context = ssl._create_unverified_context()
rslt = urllib.request.urlopen(rqt, context=context)

Bonne soirée à tous
