I tried to explain how to get the article content with MediaWiki API in an easy-to-understand manner with examples (Python 3)

Background

I am making a Wiki site using MediaWiki, and I searched for an API to get update information etc. in Python, but there are several Qiita articles and ** MediaWiki Japanese version with subtle translation **, English Since there was only information on MediaWiki, I decided to write an article for those who are thinking about using API in the future. This API is basically ** usable for MediaWiki sites other than Wikipedia **, so it is quite versatile. Please note that the detailed explanation may be wrong and it is a little difficult to read because it is Qiita's first post ...

Parameters to use

These are the main parameters used to acquire the content of this article. Regarding the parameters, This Qiita article: Get Wikipedia information using MediaWiki API introduces in detail, so there are other things besides getting the article content. If you do, I think you should refer to it. Note: I can hit it from the link, but I use `` `requests``` for readability.

Implementation example 1

What you want to do

Get the article name with "Category: School Regulations of Chiba Prefecture" on the site kousokuwiki.org created by MediaWiki.

code

 coding: UTF-8
from urllib.request import Request, urlopen
from urllib.parse import urlencode
from urllib.error import URLError, HTTPError
import json
import requests
S = requests.Session()
# Declare the URL. In the case of wikipedia, it will be "https://jp.wikipedia.org/w/api.php".
URL = "https://kousokuwiki.org/w/api.php"

# Parameter settings.
PARAMS = {
    "action": "query",
 "cmtitle": "Category: School Regulations in Chiba Prefecture",
    "cmlimit": "500",
    "list": "categorymembers",
    "format": "json"
}

# Get information with get function
R = S.get(url=URL, params=PARAMS)
DATA = R.json()

# Extracting the required data from json
PAGES = DATA['query']['categorymembers']

# Extract only title information and store in list
Return_List=[]
for page in PAGES:
    Return_List.append(page['title'])
print(Return_List)

output

 [Chiba Prefectural Chiba Higashi High School Regulations, Chiba Prefectural Inba Akira Makoto High School Regulations, Chiba Prefectural Kokubun High School Regulations, Chiba Prefectural Narita International High School Regulations, Chiba Prefectural Matsudo International High School Regulations, Chiba Prefectural Kashiwanoha High School School rules ... (Omitted below)]

Implementation example 2

What you want to do

Get the contents of the article "School rules of Chiba Prefectural Kashiwanoha High School" on the site kousokuwiki.org created by MediaWiki.

code

 coding: UTF-8
from urllib.request import Request, urlopen
from urllib.parse import urlencode
from urllib.error import URLError, HTTPError
import json
import requests
S = requests.Session()
# Declare the URL. In the case of wikipedia, it will be "https://jp.wikipedia.org/w/api.php".
URL = "https://kousokuwiki.org/w/api.php"

# Parameter settings.
PARAMS = {
    "action": "query",
    "prop": "revisions",
 "titles": "School rules of Chiba Prefectural Kashiwanoha High School",
    "rvprop": "content",
    "format": "json"
}

# Get information with get function
R = S.get(url=URL, params=PARAMS)
DATA = R.json()

# Extracting the required data from json
CONTENT = DATA['query']['pages']
    
print(CONTENT)

output

Slice only the information you want further if necessary.

At the end

I explained the MediaWiki API, which lacks Japanese information, with examples. Other parameter explanations and implementation examples may be added in the future! We hope you find it useful.
