Semalt teilt einen Screen Scraper Quick-Start Guide

Das Internet ist reich an Daten, von Verkaufsdaten bis zu Verbrauchertrends. Daher finden Unternehmen jetzt, wie entscheidend es sein kann, solche Daten zu analysieren. Bevor Sie diese Daten analysieren können, müssen Sie sie zunächst extrahieren und in einem brauchbaren Format speichern. Und das ist neben der Tatsache, dass Sie die unnötigen Daten herausfiltern müssten, um die Fehlerspanne zu reduzieren, die während der Analysephase entsteht.

Hier kommt Screen Scraper ins Spiel. Dieses Tool kann Daten von Webseiten extrahieren und Inhalte in verschiedenen Formaten speichern. Heute sehen wir uns das Screen Scraper Tutorial an. Obwohl das Tool einfach zu bedienen ist, werden einige Programmierkenntnisse hilfreich sein, besonders bei komplexen Scraping-Projekten.

Herunterladen und Installieren der Software

Screen Scraper ist auf allen gängigen Betriebssystemen verfügbar; Sie können daher eine Kopie des Programms von seiner offiziellen Homepage herunterladen. Derzeit wird der Service in drei verschiedenen Paketen angeboten: die kostenlose Basisversion, die Pro-Version für 549 US-Dollar und die Enterprise-Version für 2799 US-Dollar. Es ist wichtig zu beachten, dass Sie die kostenpflichtige Version 30 Tage lang testen können. Dies wird empfohlen, um zu vermeiden, dass Sie für einen Service bezahlen, der nicht Ihren Anforderungen entspricht. Gehen Sie voran und installieren Sie das Programm und schließen Sie das Setup ab.

Proxy Server Setup

Screen Scraper basiert auf der Aufzeichnung der Antworten zwischen einem Webserver und Ihrem Webbrowser. Dazu müssen Sie einen Proxy-Server konfigurieren. Im Wesentlichen sitzt ein Proxyserver zwischen einem Browser und einem Webserver. Jedes Mal, wenn Sie auf einen Link klicken, sendet Ihr Browser eine Anfrage an einen Zielserver.

Fahren Sie fort und konfigurieren Sie Ihren Browser für die Verwendung der Proxy-Sitzung. Dort finden Sie Anleitungen, wie Sie diese Aufgabe in jedem Browser ausführen können. Einmal eingestellt, sendet Ihr Browser alle Anfragen über den Screen Scraper-Proxy. Auf diese Anforderungen stützt sich der Screen Scraper. Sie werden auch als Proxy-Transaktionen bezeichnet.

Mehrere Proxy-Transaktionen können in einem einzigen Klick enthalten sein. Der Scrapper muss daher nur die sinnvollen Transaktionen herausfiltern und identifizieren. Diese werden im nächsten Schritt verwendet.

HTTP-Transaktionen aufzeichnen

Starten Sie den Browser, der jetzt den Proxy-Server verwendet, und gehen Sie zu einer beliebigen URL. Screen Scraper zeichnet diesen Vorgang automatisch auf und ist in der HTTP-Transaktionstabelle verfügbar.

Sie können auf die einzelne Transaktion klicken, um Details wie HTTP-Header und POST-Daten anzuzeigen.

Scrapable-Datei erstellen

Starten Sie, indem Sie eine neue Scraping-Sitzung erstellen. Dies wird alle Dateien und andere Objekte enthalten, mit denen Sie Inhalte von einer bestimmten Website extrahieren können. Die Transaktionen in Bezug auf dieses neue Projekt werden angezeigt, indem Sie auf die Registerkarte "Fortschritt" klicken. Es ist wichtig zu beachten, dass jeder dieser Vorgänge verwendet werden kann, um eine scrapeable Datei zu erstellen, indem Sie einfach "Scrapeable Datei erstellen" im Dropdown-Feld auswählen.

Erstellen eines Extraktormusters

Ein Extraktormuster ist ein Codeblock, der spezielle Token enthält, die mit den Datenelementen übereinstimmen, die Sie extrahieren möchten. Sie sind Textlabels, umgeben von Begrenzern '@ ~.' Dies ist, wo ein gutes Verständnis von HTML kommt, wie Sie Extraktor-Token gefolgt von den Namen und einzelnen Attributen hinzufügen müssen.
