Semalt explique comment effectuer des opérations Web Scraping gratuitement

 

Un racleur de bande est un type de robot développé pour courir à travers la bande pages pour extraire toutes les données nécessaires. Content Grabber est un outil de grattage Web gratuit créé pour gérer même avec des types complexes de données.

Tout d'abord, vous pouvez essayer la version d'essai de l'agent pour commencer. Pendant la période d'essai, un agent de raclage web simple mais personnalisé peut être développé pour vous. Cependant, vous devez comprendre que l'agent d'essai est créé pour démontrer son potentiel et qu'il ne peut pas correspondre à tous vos besoins. En outre, vous ne pouvez obtenir qu'un seul agent pour un seul site Web.

Si vous avez besoin d'un agent de grattage Web capable de gérer des tâches de grattage complexes ou si vous souhaitez récupérer des données de plusieurs sites Web, vous devrez acheter sa version payante. Cependant, au cours de cet article, nous allons parler des options Content Grabber que vous pouvez obtenir gratuitement. Vous pouvez donc demander un agent de grattage Web gratuit en envoyant un courriel à demo@contengrabber.com. Habituellement, vous recevrez un agent gratuit dans les 24 heures ouvrables après l'envoi d'une demande. Cependant, cela peut prendre plus de temps si vous envoyez la demande pendant une période occupée.

Étapes pour demander un agent grattoir gratuit

Tout d'abord, vous devez fournir une URL de démarrage. C'est l'URL d'une page Web où votre agent libre commencera à extraire des données.

Vous devez expliquer quel type de données vous souhaitez extraire de votre site Web. La méthode la plus efficace pour y parvenir consiste à fournir des captures d'écran des pages Web avec les données requises marquées en caractères gras.

Vous devriez éviter de donner des instructions vagues comme «toutes les données doivent être extraites du site Web», car ce n'est pas ce dont vous avez réellement besoin. Cependant, s'il s'avère que vous avez littéralement besoin de toutes les données sur votre site Web, utilisez Website Downloader au lieu de Content Grabber.

Vous devez également spécifier le format de données qui vous convient le mieux. Les formats habituels sont XML, CSV et Excel.

L'étape suivante consiste à envoyer toutes les informations énumérées ci-dessus à demo@contentgrabber.com et à obtenir une réponse et un exemple d'extrait de données dans les 24 heures ouvrables ou un peu plus dans certains cas.

Installez la version d'évaluation de Content Grabber pour vous familiariser avec l'outil. Vous obtiendrez un fichier d'agent exporté qui peut être importé dans Content Grabber en sélectionnant Import Agent dans le menu File de Content Grabber.

Vous pouvez maintenant utiliser l'agent de grattage Web dans le menu Exécution de l'outil de saisie de contenu. Vous devez garder à l'esprit que la version d'évaluation s'arrêtera immédiatement après le chargement de 100 pages.
