Semalt fournit des questions utiles sur 5 Top Web Scraper

Souvent, l'information dont nous avons besoin est piégée dans un site, et nous ne peut pas gratter ou ramper correctement. Alors que certains sites font des efforts pour présenter les données dans des formats propres et structurés, les autres ne peuvent fournir aucune fonction d'exploration ou de grattage des données. C'est pourquoi nous aurons besoin d'accéder aux meilleurs robots d'exploration, mineurs et scrapers. Ici, nous avons discuté des cinq meilleurs outils à cet égard.

1. Webhose.io:

Webhose.io nous permet d'obtenir des données en temps réel à partir de ressources et de sites en ligne. La meilleure partie est que ce programme mine et rampe les sites commodément et présente les données dans un format propre et bien organisé. Cela nous permet également d'extraire des données en fonction de leurs mots-clés, expressions, langues et nature. Les résultats finaux peuvent être obtenus sous la forme de fichiers XML, RSS et JSON. Bien que ce programme soit gratuit, vous pouvez accéder à sa version premium si vous souhaitez utiliser Webhose.io à des fins commerciales. Le plan payant vous permettra d'envoyer plusieurs requêtes HTTP au serveur principal, ce qui vous permettra de récupérer et d'explorer facilement les sites.

2. Scrapy:

Scrapy est un framework de grattage et d'exploration puissant et étonnant sur Internet. Sa meilleure partie est que ce programme est soutenu par une communauté d'experts, avec qui vous pouvez entrer en contact pour des conseils utiles et des tutoriels à tout moment, n'importe où. Il aide à gratter et analyser vos données et les enregistre dans différents formats tels que CSV et JSON.

3. Hub de contournement:

Si vous n'êtes pas à l'aise avec les codes, Outwit Hub vous fournira l'interface visuelle utile, facilitant l'exploration et l'exploitation des données. Sa version hébergée est disponible sur le site officiel, et la version gratuite peut être téléchargée depuis n'importe quel magasin en ligne. Outwit Hub est une extension Firefox qui ne nécessite pas de compétences en programmation.

4. Octoparse:

Tout comme Outwit Hub, Octoparse est un grattoir web puissant, un robot d'exploration et un data miner. Il gère à la fois les sites statiques et dynamiques en utilisant Javascript, les cookies, les redirections et AJAX. Ce programme web aidera à extraire n'importe quel site ou blog et extraira des types de données basiques et avancés. Toutes les informations utiles dont vous avez besoin peuvent être trouvées dans la zone de stockage en nuage d'Octoparse. Il vous permet d'extraire des sites Web en une heure, et vous obtiendrez la meilleure qualité avec l'API Octoparse. Permettez-moi de vous dire que ce freeware ne supporte que Windows et n'est disponible pour aucun autre système d'exploitation.

5. Web Scraper pour Chrome:

Si vous utilisez Google Chrome comme navigateur Web principal, vous devez opter pour Web Scraper. Il s'agit d'un programme d'exploration et d'exploration exceptionnel qui vous permet de créer des sitemaps pour vos blogs personnels et vos sites Web professionnels. Vous n'avez qu'à télécharger, installer et ajouter ce scraper à votre navigateur Chrome et voir comment il va extraire les données de vos sites Web. Vous pouvez également importer les sitemaps ou utiliser ses modèles pour améliorer l'apparence générale et les performances de votre site Web. Il sauvegardera vos données extraites dans les fichiers CSV ou dans son propre dossier Archive.
