Semalt stellt die besten Web-Crawler-Tools vor, um Webseiten zu kratzen

Web-Crawling, oft als Web-Scraping bezeichnet, ist der Prozess, wenn ein automatisiertes Skript oder Programm durchsucht das Netz methodisch und umfassend und zielt auf die neuen und vorhandenen Daten ab. Oft sind die Informationen, die wir brauchen, in einem Blog oder auf einer Website gefangen. Während einige Websites versuchen, die Daten im strukturierten, organisierten und sauberen Format darzustellen, tun dies viele nicht. Daten-Crawling, Verarbeitung, Scraping und Reinigung sind für ein Online-Geschäft notwendig. Sie müssten Informationen aus mehreren Quellen sammeln und für geschäftliche Zwecke in den proprietären Datenbanken speichern. Früher oder später müssen Sie durch die Online-Foren und -Gemeinschaften gehen, um Zugriff auf verschiedene Programme, Frameworks und Software zu erhalten, um Daten von einer Site zu erhalten.

Cyotek WebCopy:

Cyotek WebCopy ist einer der besten Web Scraper und Crawler im Internet. Es ist bekannt für seine webbasierte, benutzerfreundliche Oberfläche und macht es uns leicht, den Überblick über mehrere Crawls zu behalten. Darüber hinaus ist dieses Programm erweiterbar und wird mit mehreren Backend-Datenbanken geliefert. Es ist auch für seine Message Queues-Unterstützung und praktische Funktionen bekannt. Das Programm kann leicht fehlgeschlagene Webseiten wiederholen, Websites oder Blogs nach Alter durchsuchen und eine Vielzahl von Aufgaben für Sie ausführen. Cyotek WebCopy benötigt nur zwei bis drei Klicks, um Ihre Arbeit zu erledigen und kann Ihre Daten einfach crawlen. Sie können dieses Tool in verteilten Formaten verwenden, wobei mehrere Crawler gleichzeitig arbeiten. Es ist von Apache 2 lizenziert und wird von GitHub entwickelt.

HTTrack:

HTTrack ist eine berühmte Crawling-Bibliothek, die um die berühmte und vielseitige HTML-Parsing-Bibliothek namens Beautiful Soup herum aufgebaut ist. Wenn Sie der Meinung sind, dass Ihr Web-Crawling ziemlich einfach und einzigartig sein sollte, sollten Sie dieses Programm so schnell wie möglich ausprobieren. Es wird den Crawlingprozess einfacher und einfacher machen. Das einzige, was Sie tun müssen, ist, auf ein paar Kästchen zu klicken und die gewünschten URLs einzugeben. HTTrack ist lizenziert unter der MIT-Lizenz.

Octoparse:

Octoparse ist ein leistungsfähiges  Web-Scraping-Tool , das von der aktiven Community der Webentwickler unterstützt wird und Ihnen beim Aufbau Ihrer Geschäftlich bequem. Außerdem können alle Arten von Daten exportiert, gesammelt und in verschiedenen Formaten wie CSV und JSON gespeichert werden. Es hat auch ein paar eingebaute oder Standard-Erweiterungen für Aufgaben im Zusammenhang mit Cookie-Behandlung, User-Agent-Spoofs und eingeschränkten Crawlern. Octoparse bietet den Zugriff auf seine APIs, um Ihre persönlichen Ergänzungen zu erstellen.

Getleft:

Wenn Sie mit diesen Programmen aufgrund ihrer Codierungsprobleme nicht vertraut sind, können Sie Cola, Demiurge, Feedparser, Lassie, RoboBrowser und andere ähnliche Tools. Getleft ist in jedem Fall ein weiteres leistungsstarkes Tool mit vielen Optionen und Funktionen. Damit müssen Sie kein Experte für PHP- und HTML-Codes sein. Dieses Tool wird Ihren Web-Crawling-Prozess einfacher und schneller als andere traditionelle Programme machen. Es funktioniert direkt im Browser und generiert kleine XPaths und definiert URLs, damit sie richtig durchsucht werden. Manchmal kann dieses Tool in die Premium-Programme ähnlicher Art integriert werden.
