[Python] 공공데이터포털 OpenAPI 호출 에러 SSLError: HTTPSConnectionPool(host='apis.data.go.kr', port=443)

기존 공공데이터 API 화면에서 호출을 진행 했을 때는 수행이 잘 되다가 주피터노트북에서 호출하려고 보니 아래와 같은 에러가 발생하는 경우가 생겼다 ..

import requests
import chardet
import xml.etree.ElementTree as ET
import logging

# API 요청
url = 'https://apis.data.go.kr/1160100/service/GetFinaStatInfoService_V2/getSummFinaStat_V2'
serviceKey = ''
params = {'serviceKey': serviceKey, 'pageNo': '1', 'numOfRows': '10', 'resultType': 'xml', 'bizyear': '2024'}

response = requests.get(url, params=params)
detected_encoding = chardet.detect(response.content)['encoding']
logger.info(f"Detected Encoding: {detected_encoding}")

decoded_text = response.content.decode(detected_encoding)

SSLError: HTTPSConnectionPool(host='apis.data.go.kr', port=443)

url에서 s를 빼고 호출하니 오류없이 정상적으로 실행되었다.

url = 'http://apis.data.go.kr/1160100/service/GetFinaStatInfoService_V2/getSummFinaStat_V2'
