Google検索結果を取得する（Python）

概要

OlostepのAPIを使用すると、パーサーを利用して検索エンジンの結果から構造化されたデータを抽出できます。これらのパーサーは、検索結果の生のHTMLをクリーンで構造化されたJSONデータに変換し、分析やアプリケーションへの統合に備えます。

統合例

検索結果から解析されたJSONコンテンツを取得するには、formatsパラメータにjsonを含め、parserオブジェクトにパーサーの名前@olostep/google-searchを指定する必要があります。以下は、構造化された形式でGoogle検索結果を取得する方法です：

import requests
import json

endpoint = "https://api.olostep.com/v1/scrapes"
payload = {
    "formats": ["json"],
    "parser": {"id": "@olostep/google-search"},
    "url_to_scrape": "https://www.google.com/search?q=alexander+the+great&gl=us&hl=en",
    "wait_before_scraping": 0,
}
headers = {
    "Authorization": "Bearer <YOUR-API-KEY>",
    "Content-Type": "application/json"
}
response = requests.request("POST", endpoint, json=payload, headers=headers)
print(json.dumps(response.json(), indent=4))

レスポンス形式

Google検索パーサーを使用してOlostep APIにリクエストを送信すると、以下のようなJSONレスポンスを受け取ります：
