Google Zoekresultaten Scraper met Olostep

Deze gids laat zien hoe je de Olostep API kunt gebruiken om Google zoekresultaten te scrapen en ze te parseren naar gestructureerde JSON-gegevens. Dit is vooral nuttig voor het automatiseren van onderzoekstaken, het verzamelen van concurrentie-informatie, of het bouwen van applicaties die zoekgegevens vereisen.

Hoe Het Werkt

Het onderstaande voorbeeld in Javascript laat zien hoe je naar een LinkedIn profiel-URL van een specifieke persoon (Patrick Collison) kunt zoeken met behulp van Google zoekopdracht en Olostep’s google zoekparser @olostep/google-search
async function scrapeGoogleSearch(apiKey, query = "site%3Alinkedin.com+Patrick+Collison") {
  const endpoint = "https://api.olostep.com/v1/scrapes";

  const payload = {
    "formats": ["json"],
    "parser": {"id": "@olostep/google-search"},
    "url_to_scrape": `https://www.google.com/search?q=${encodeURIComponent(query)}&gl=us&hl=en`,
    "wait_before_scraping": 0,
  };

  const headers = {
    "Authorization": `Bearer ${apiKey}`,
    "Content-Type": "application/json"
  };

  try {
    const response = await fetch(endpoint, {
      method: "POST",
      headers: headers,
      body: JSON.stringify(payload)
    });

    const data = await response.json();
    console.log(JSON.stringify(data, null, 4));
    return data;
  } catch (error) {
    console.error("Error:", error);
    throw error;
  }
}

// Vervang <API_KEY> door je eigen Olostep API-sleutel
scrapeGoogleSearch("<API_KEY>");

Responsformaat

Wanneer je een verzoek doet aan de Olostep API met de Google Zoekparser, ontvang je een JSON-respons zoals het onderstaande voorbeeld:

Olostep biedt ook een gehost JSON-bestand met de gestructureerde zoekresultaten. Je kunt toegang krijgen tot het JSON-bestand via het veld json_hosted_url in de respons: Als je ook de HTML- en Markdown-inhoud van de zoekresultaten wilt verkrijgen, kun je deze formaten opnemen in de formats parameter en Olostep zal ze in de respons retourneren en gehoste URL’s voor elk formaat bieden.

Voorbeeldgebruiksscenario’s

scrapeGoogleSearch(apiKey, "\"Company X\" vs \"Company Y\" comparison");

Belangrijke Opmerkingen

  1. Zoekparameters: De gl=us en hl=en parameters stellen de geolocatie in op de VS en de taal op Engels. Pas deze aan indien nodig.
