Semalt Shares A Screen Scraper Guida rapida

Feb 08, 2018

Internet è pieno di dati, che vanno dai dati di vendita alle tendenze dei consumatori. Pertanto, le aziende stanno scoprendo quanto sia cruciale l'analisi di tali dati. Ma prima di poter analizzare questi dati, devi prima estrarlo e memorizzarlo in un formato utilizzabile. E questo a parte il fatto che dovresti filtrare i dati non necessari per ridurre il margine di errore che si presenta durante la fase di analisi.

È qui che entra in gioco Screen Scraper, strumento in grado di estrarre dati da siti Web e archiviare i contenuti in vari formati. Oggi guarderemo il tutorial di Screen Scraper. Sebbene lo strumento sia facile da usare, alcune conoscenze di programmazione saranno utili soprattutto quando si gestiscono progetti di scraping complessi.

Download e installazione del software

Screen Scraper è disponibile su tutti i principali sistemi operativi; puoi, quindi, scaricare una copia del programma dalla sua homepage ufficiale. Attualmente, il servizio è offerto in tre pacchetti diversi: la versione gratuita di base, la versione pro che costa $ 549 e la versione enterprise disponibile per $ 2799. È importante notare che è possibile testare la versione a pagamento per 30 giorni e si consiglia di evitare di pagare per un servizio che potrebbe non essere adatto alle proprie esigenze. Vai avanti e installa il programma e completa la configurazione.

Proxy Server Setup

Screen Scraper si basa sulla registrazione delle risposte tra un server Web e il browser web. Affinché questo accada, sarà necessario configurare un server proxy. Essenzialmente, un server proxy si trova tra un browser e un server web, ogni volta che si fa clic su un collegamento il browser invierà una richiesta a un server di destinazione.

Andare avanti e configurare il browser per utilizzare la sessione proxy, ci sono tutorial su come si può andare su questa attività su ciascun browser. Una volta impostato, il browser invierà tutte le richieste tramite il proxy dello screen scraper. Queste richieste sono ciò su cui si basa lo Screen Scraper. Sono anche noti come transazioni proxy.

Le transazioni proxy multiple possono essere contenute in un singolo clic. Lo scrapper, quindi, deve filtrare e identificare solo le transazioni utili. Questi sono quelli che verranno utilizzati nel passaggio successivo.

Registrazione di transazioni HTTP

Avviare il browser che ora utilizza il server proxy e accedere a qualsiasi URL, Screen raschietto registrerà automaticamente questa operazione e sarà disponibile nella tabella delle transazioni HTTP.

È possibile fare clic sulla singola transazione per visualizzare dettagli come intestazioni HTTP e dati POST.

Generazione di File Scrapeable

Iniziare creando una nuova sessione di raschiamento. Questo conterrà tutti i file e altri oggetti che ti permetteranno di estrarre il contenuto da un determinato sito web. Le transazioni relative a questo nuovo progetto sono visualizzate facendo clic sulla scheda di avanzamento. È importante notare che ciascuna di queste operazioni può essere utilizzata per creare un file scaricabile selezionando semplicemente "Genera file di scrapeable" nel pannello a discesa.

Creating Extractor Pattern

Un pattern extractor è un blocco di codice che contiene token speciali che corrispondono ai frammenti di dati che si desidera estrarre. Sono etichette di testo circondate da delimitatori '@ ~'. È qui che entrerà in gioco una buona conoscenza dell'HTML, poiché dovrai aggiungere token estrattori seguiti da nomi e singoli attributi.
