Quick and sloppy script to clear out unused fields from Solr's schema API

clear_fields.py

import json

from urllib.parse import urlencode
from urllib.request import Request, urlopen

solr_url = 'http://localhost:8983/solr/gettingstarted/schema'

luke_file = open('luke-json-output.json', 'r')
luke_json = json.load(luke_file)
luke_file.close()

for field in luke_json['fields']:
    if 'docs' not in luke_json['fields'][field]:
        post_fields = {'delete-field': {"name": field}}
        request = Request(solr_url, urlencode(post_fields).encode())
        urlopen(request).read().decode()
