KeyError Solution w/o Library

[cho104]

Seems to be working properly on a large dataset (used 40k sentence dataset) (Last time checked: Oct 2024)
This may not provide all the features offered by the original library.

• You may need to implement a feature to skip sentence after a few rejections as the api refuses to spell check certain sentences.

import requests
import json
import re

class SpellChecker:
    def __init__(self):
        self.passport_key = None
        self.base_url = None

    def fetch_passport_key(self):
        headers = {
            'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/129.0.0.0 Safari/537.36',
            'Referer': 'https://search.naver.com/',
        }
        response = requests.get("https://search.naver.com/search.naver?query=%EB%A7%9E%EC%B6%A9%EB%B2%95%20%EA%B2%80%EC%82%AC%EA%B8%B0", headers=headers)
        passport_key_match = re.search(r'(?<={new SpellingCheck\({API:{checker:").*?(?="},selector)', response.text)
        if not passport_key_match:
            return "Error: Unable to retrieve passport key"
        self.base_url, self.passport_key = passport_key_match.group(0).split("?passportKey=")

    def spell_check(self, text):
        if self.passport_key is None or self.base_url is None:
            self.fetch_passport_key()
        payload = {
            'passportKey': self.passport_key,
            'where': 'nexearch',
            'color_blindness': 0,
            'q': text
        }
        headers = {
            'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, Gecko) Chrome/129.0.0.0 Safari/537.36',
            'Referer': 'https://search.naver.com/',
        }
        result_response = requests.get(self.base_url, headers=headers, params=payload)
        return json.loads(result_response.text)['message']['result']['notag_html']

# Usage
checker = SpellChecker()
result = checker.spell_check("sentence for spell check")
print(result)
