Ошибка сертификата при использовании API Википедии в Python 3.7

0 голосов
/ 23 мая 2019

Когда я пытаюсь использовать API Википедии, я получаю сообщение об ошибке сертификата.

Это для помощника. Я пишу код на школьном компьютере и думаю, что это было сделано администрацией, поскольку я получил ошибку сертификата при использовании NPM ранее.

Вот код, который я использую: 

    wikiSearch = query.strip("wiki ")
    outputs = wikipedia.summary(wikiSearch, sentences=3)

Я думал, что это вернет первые три предложения статьи, как это делается в python 2.7, но вместо этого возвращает это длинное сообщение об ошибке:

Edit:

Теперь я получаю эту ошибку:

Как вы уже упоминали, вы сталкивались с подобной ошибкой при работе с NPM, скорее всего, это связано с настройкой прокси-сервера вашей администрацией.

Вы можете настроить прокси для любого стороннего модуля для подключения к Интернету. По умолчанию urlopen urllib3 использует переменную среды http_proxy, чтобы определить, какой HTTP-прокси использовать.

запустите эту команду в CMD перед запуском вашего приложения на Python 

export http_proxy='http://myproxy.proxy.com:1234'

=============================================== =============

если вы не знаете своего прокси, вы можете попробовать этот обходной путь. выполните эту команду в CMD перед запуском приложения python 

export CURL_CA_BUNDLE=''

или добавьте эти строки в свой код, чтобы избежать добавления переменной окружения вручную каждый раз. 

import os
os.environ['CURL_CA_BUNDLE'] = ""

если вы получаете InsecureRequestWarning и хотите его отключить, вы можете сделать следующее. 

import wikipedia
import os
import urllib3
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)
os.environ['CURL_CA_BUNDLE'] = ""
os.environ['PYTHONWARNINGS']="ignore:Unverified HTTPS request"
print(wikipedia.wikipedia.summary("Google"))

Надеюсь, это поможет.
