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

 

공공데이터포털에서 한국장애인고용공단 장애인 구인 실시간 현황 api를 호출해 데이터를 가져오는 과정에서 오류가 발생했다.  

공공데이터 포털에서 api를 호출했을 때는 성공적으로 호출했다. 

 

import requests
import pprint
import json

PAGE_NO = '1'
NUM_OF_ROWS= '1000'
API_KEY = '' # Decoding 인증키

url = 'https://apis.data.go.kr/B552583/job/job_list_env'

params = {
    'serviceKey': API_KEY,
    'pageNo': PAGE_NO,
    'numOfRows': NUM_OF_ROWS
}
response = requests.get(url, params=params)
contents = response.text

pprint.pprint(contents)

 

직접 주피터노트북에서 호출하려고 하니 계속 아래와 같은 오류가 났다. 

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

https에서 s를 빼고 http로 호출하니 성공적으로 실행되었다. 

url = 'http://apis.data.go.kr/B552583/job/job_list_env'
