Semalt: come estrarre immagini dai siti web

Feb 08, 2018

Conosciuto anche come raschiatura del nastro, l'estrazione del contenuto web è la soluzione definitiva per estrarre immagini, testo e documenti da siti Web in formati utilizzabili. Siti Web statici e dinamici visualizzano il contenuto agli utenti finali come di sola lettura, rendendo difficile il download di contenuti da tali siti.

Quando si tratta di marketing online e di contenuti, i dati sono uno strumento essenziale. Per fare affari coerenti e validi, sono necessarie fonti di dati complete che visualizzano informazioni in formati strutturati. È qui che entra in gioco lo scraping dei contenuti.

Perché i crawler di immagini online?

Nel moderno settore del content marketing, i proprietari dei siti web utilizzano i file robots.txt per indirizzare gli scrapers web delle sezioni del sito web a raschiare e dove evitare. Tuttavia, la maggior parte dei web scrapers va contro i diritti d'autore e le politiche dei siti Web estraendo il contenuto dai siti "completa disallow".

Recentemente, la piattaforma LinkedIn ha recentemente intentato una causa contro gli estrai del web che hanno preso l'iniziativa di estrarre vaste serie di dati dal sito web di LinkedIn senza controllare il file di configurazione robots.txt del sito. Come webmaster, l'utilizzo di strumenti di web scraping per ottenere informazioni da alcuni siti può compromettere la tua campagna di scraping web.

Un crawler di immagini online è ampiamente utilizzato da blogger e operatori di marketing per recuperare le immagini di massa da siti Web dinamici e di e-commerce. Le immagini raschiate possono essere visualizzate direttamente come miniature o salvate su un file locale per l'elaborazione avanzata. Si noti che il database CouchDB è raccomandato per progetti di scraping di immagini su larga scala e avanzati.

Caratteristiche dei crawler di immagini online

Un crawler di immagini online raccoglie grandi quantità di immagini da siti Web ed elabora le immagini raschiate in formati strutturati generando report XML e HTML. Un crawler di immagini online comprende le seguenti funzionalità pre-confezionate:

Supporto completo della funzione di trascinamento della selezione che consente di salvare singole immagini sul file locale
Registrazione di immagini raschiate generando report XML e HTML
Estrazione simultanea di immagini singole e multiple
Osservazione esplicita di tag HTML Meta description e file di configurazione robots.txt

Getleft

Getleft è un crawler di immagini online e un web raschietto utilizzato per estrarre immagini e testi dai siti web. Per raschiare le pagine Web utilizzando Getleft, inserire l'URL del sito Web da raschiare e identificare le pagine Web di destinazione contenenti immagini. Questo raschietto modifica le pagine Web e i collegamenti originali per la navigazione locale.

Scraper

Scraper è un'estensione Google Chrome che genera automaticamente XPaths per determinare gli URL da sottoporre a scansione e scrap. Scraper è consigliato per progetti di scraping web su larga scala.

Scrapinghub

Scrapinghub è un raschiatore di immagini di alta qualità che converte le pagine Web in contenuti strutturati e ben organizzati. Questo raschietto di immagini comprende un rotatore proxy che supporta l'aggiramento delle contromisure dei bot per eseguire la scansione dei siti protetti da bot. L'hub di raschiamento è ampiamente utilizzato dagli scraper Web per scaricare immagini di massa attraverso la semplice API (Application Programming Interface) HTTP.

Dexi.io

Dexi.io è un raschiatore di immagini basato su browser che fornisce server proxy Web per le immagini raschiate. Questo raschietto immagine consente di estrarre immagini da siti Web sotto forma di file CSV e JSON.

Al giorno d'oggi, non hai bisogno di migliaia di stagisti per copiare manualmente le immagini dai siti web. Un crawler di immagini online è la soluzione definitiva per estrarre grandi quantità di immagini da pagine web dinamiche. Usa i crawler di immagini online sopra evidenziati per ottenere enormi quantità di immagini in formati utilizzabili.
