Semalt Guide For Beginners: Hoe Websites te schrapen

Jan 22, 2018

Webscraping helpt gebruikers om verschillende gegevens van sites over het net te extraheren. Als u vandaag de juiste extraherenstools gebruikt, kunt u bijna elke gewenste inhoud downloaden. Er zijn een aantal online softwareprogramma's die een aantal fantastische extractiemogelijkheden bieden. Schrapen heeft zelfs veel toepassingen. U kunt bijvoorbeeld verschillende lijsten, contacten, e-mails, producten en nog veel meer verkrijgen. Als gevolg hiervan gebruiken veel SEO-bedrijven en e-shops deze methode om de kwaliteit van hun services te verbeteren.

Juridische kwesties

Er zijn websites die geen scraping toestaan. Gebruikers moeten dus heel voorzichtig zijn bij het bezoeken van een webpagina om bepaalde inhoud te downloaden. Het is noodzakelijk om de algemene voorwaarden van elke website die u bezoekt te lezen om ervoor te zorgen dat u geen wetten overtreedt. Anders kunt u een aantal problemen tegenkomen, zoals juridische kwesties. Webzoekers moeten onthouden dat zij webscraping kunnen gebruiken als een effectief hulpmiddel voor hun werk en inhoud kunnen extraheren om goede redenen. U wilt bijvoorbeeld de prijzen van andere producten of contactgegevens van potentiële klanten vinden. Dit kan helpen om uw services te verbeteren door hoogwaardige producten tegen goede prijzen aan te bieden.

Python Software Program

Webscraping kan worden uitgevoerd met behulp van verschillende programmeertalen. Zo kunnen webschrapers gebruikmaken van het Python-softwareprogramma, een eenvoudige en dynamische programmeertaal die gebruikers vele nuttige pakketten biedt. In feite is het een geweldig extractietool voor zowel beginners als ervaren gebruikers. Met Python is het zo eenvoudig om binnen enkele minuten gegevens te extraheren door een van de bibliotheken te gebruiken. U kunt bijvoorbeeld gebruikmaken van Beautiful Soup, een geweldige tool om informatie van het web te verzamelen.

HTML-code

Gebruikers die via het web toegang tot een bepaalde site moeten hebben, moeten een HTML-code downloaden om deze later te analyseren. HTML is een code die alle relatieve informatie bevat die een gebruiker nodig heeft. Als gevolg hiervan kan de vereiste informatie, zoals contactlijsten of prijzen, worden verkregen door deze code te analyseren. Webzoekers kunnen een bepaalde bibliotheek gebruiken, zoals Scrapy of Beautiful Soup, om de HTML-code te ontleden en binnen enkele seconden alle benodigde gegevens te ontvangen. Maar hoe kunt u de HTML-code ontleden? Eerst moet je controleren of het HTML-adres dat je hebt correct is en dan de paginatitel verifiëren. U kunt doorgaan door alle specifieke informatie van deze pagina te verzamelen. Om te slagen, moet je de structuur van de HTML-code analyseren. Doe dit met behulp van de Chrome Inspector.
