Esperto di Semalt dice come estrarre immagini da un sito web

Feb 09, 2018

Al giorno d'oggi, il web è diventato senza dubbio il riferimento più ampio sia per i non strutturati che per i semi dati strutturati. I siti Web dinamici visualizzano i dati in diversi formati, rendendo un po 'difficile estrarre i dati da questi tipi di siti contemporaneamente. Ecco perché è necessario navigare e afferrare il software di scraping per recuperare i dati di destinazione in tempo reale.

Lo scraping Web viene utilizzato per estrarre immagini, testi e file dai siti Web a un singolo foglio di calcolo o database. Al giorno d'oggi, le varietà di strumenti di scraping di immagini sono gratuite sul Web. In questo post, imparerai come estrarre le immagini da un sito web utilizzando diversi navigatori e acquisisci gli scraper di immagini.

Ci sono alcuni popolari scrapers di immagini da considerare:

Web Scraper

Web Scraper è un plugin di Google Chrome di alta qualità utilizzato per estrarre immagini da siti Web moderni. Con Web Scraper, puoi creare un piano che ti consentirà di navigare ed estrarre immagini dal sito web di destinazione.

A differenza di altri scraper di immagini che estraggono le immagini solo da HTML, raschia web anche i siti di caricamento JavaScript. Dopo aver raschiato un sito, è possibile scaricare le immagini in formato CSV o salvare le immagini in CouchDB. Nota che CouchDB è comunemente usato per progetti avanzati di scraping di immagini.

Owidig image scraper

Owidig è un'estensione Google Chrome che comprende funzionalità incorporate pre-confezionate per semplificare l'esperienza di scraping delle immagini. Puoi utilizzare Owidig image scraper per estrarre le immagini collegate alle directory dei file tramite un URI (Uniform Resource Identifier) nell'HTML e incollare il sito di destinazione nel tuo plugin. Tuttavia, se le immagini sono collegate a una fonte esterna usando Python o JavaScript, devi proxy l'indirizzo di origine ideale.

Octoparse scraping tool

Octoparse è un raschiatore di immagini fai-da-te altamente raccomandato sia per utenti inesperti che esperti. Con Octoparse puoi estrarre gli URL delle immagini di destinazione e salvarli utilizzando la scheda Estensione di Google Chrome.

Installare Octoparse sulla macchina e lasciare che il raschietto esegua il resto dell'attività di raschiatura immagine. Nella maggior parte dei casi, gli scraper web utilizzano Octoparse per scaricare ed estrarre un numero enorme di immagini dai siti Web. Nell'attuale settore del marketing, il web scraping è diventato un'attività unica che può essere eseguita in modo efficiente anche dai principianti.

OutWit Hub

Si tratta di un semplice raschiatore di immagini che fornisce un raschiamento del nastro efficiente senza richiedere conoscenze tecniche avanzate o capacità di programmazione. OutWit Hub incorpora facilmente un motore di scraping, estrattori di dati e un browser web. Questo software analizza la pagina Web di destinazione per raschiare automaticamente le immagini disponibili.

A differenza di altri raschietti immagine, OutWit Hub carica le immagini anziché copiare semplicemente i collegamenti. Se stai cercando per navigare e afferrare il software di scrap scrap, OutWit Hub è lo strumento migliore.

Se si utilizza un servizio di scraping o un linguaggio di programmazione, trovare i tag immagine ed estrarre gli attributi da ciascun oggetto identificato. Recupera gli URL dell'immagine di destinazione utilizzando la richiesta HTTP e salva i risultati nel tuo file system definito come "file immagine". Per i progetti su piccola scala, è possibile identificare l'immagine di destinazione, fare clic con il tasto destro sull'immagine e toccare il pulsante "Salva" per scaricare e salvare l'immagine come file locale.
