Semalt mostra come estrarre immagini dai siti web usando Octoparse

Le aziende e le organizzazioni si affidano a dati completi per definire strategie e prendere decisioni di business. Con il web scraping, il recupero di enormi quantità di dati utili dai siti Web è a portata di clic. Il web scraping è una tecnica utilizzata dai webmaster e dai marketer per estrarre testi, immagini e documenti dalla rete.

Octoparse

Al giorno d'oggi, ritagliare le immagini dai siti di caricamento statico e JavaScript è diventato un compito quotidiano da eseguire. È possibile utilizzare Octoparse per estrarre le immagini di destinazione come l'URL di dove si trova l'immagine su una pagina Web. In questa guida imparerai come utilizzare lo strumento di scraping "scarica dagli URL" per recuperare grandi quantità di immagini dai siti web.

Alcuni strumenti di scraping web sono stati proposti per attività di scraping web. Gli strumenti di scraping Web sono progettati per analizzare sia i siti di caricamento statici che quelli JavaScript. Se non sei un programmatore, non devi andare nel panico. Estrarre immagini da siti usando Octopar è semplice come ABC.

La scelta dello strumento di scraping web con cui lavorare dipende dai tuoi progetti. Alcuni degli strumenti sono progettati per estrarre grandi quantità di immagini allo stesso tempo mentre altre si adattano a una singola fonte per richieste. Si noti che la maggior parte dei siti di e-commerce impedisce agli utenti di raschiare i siti. In tal caso, si consiglia di controllare i file di configurazione robots.txt dei siti Web per le autorizzazioni.

Come estrarre le immagini dai siti Web?

  • Utilizzando il browser integrato, aprire la pagina Web che comprende le immagini da recuperare.
  • Configurare l'impaginazione per l'estrazione per ottenere tutti gli URL delle immagini di destinazione.
  • Selezionare l'icona "Crea un elenco di oggetti" nell'angolo in alto a sinistra del browser e modificare l'elenco compilato.
  • Fare clic su "Loop" per elaborare l'elenco compilato.
  • Iniziare a estrarre tutti gli URL delle immagini facendo clic su "Estrai testo". Per ottenere risultati affidabili, l'indirizzo dell'immagine deve essere tag immagine primario Ricordarsi di individuare il tag immagine appropriato prima di iniziare a estrarre tutte le immagini da una pagina Web.
  • Per eseguire il processo di estrazione sul computer locale, fare clic su "Estrazione locale". dopo aver finito con la configurazione di tutte le regole di estrazione dell'immagine da un sito Web.
  • Dopo aver ottenuto gli URL di tutte le immagini in una pagina Web, esportare i dati raschiati in un file locale o in un formato di database. 

Gli URL raschiati di tutte le immagini possono essere esportati in CouchDB o in Microsoft Excel. La scelta del database da considerare dipende dalla quantità di immagini da esportare. Per concludere il processo di estrazione delle immagini, utilizzare Scheda Estensione di Google Chrome e fai clic su "Salva" per scaricare tutte le immagini. Inserisci i link di download ottenuti su yo la tua query di ricerca del browser per iniziare.

Copia-incolla gli URL delle immagini nella tua casella di testo e clicca sul pulsante "Download" per salvare le immagini sul tuo PC. Estrarre le immagini dai siti web usando Octoparse è solo un clic di distanza. Non lasciare che le conoscenze di programmazione mettano a repentaglio i progetti di scraping delle immagini. Scarica e salva le immagini dai siti di caricamento statico e JavaScript con facilità utilizzando le esercitazioni Octoparse.

Thanks for the article, George. Can Octoparse extract images from websites that require JavaScript interaction, like clicking buttons to load dynamic content?
George Forrest
Hi Daniel, Octoparse can extract images from websites that require JavaScript interaction, including scenarios where clicking buttons loads dynamic content. Octoparse provides functionalities like Click Element and Wait for Element that allow you to interact with dynamic elements and ensure that the necessary content is loaded before proceeding with image extraction. Octoparse's support for JavaScript rendering and interactive features enables successful extraction of images from websites with JavaScript-driven content. If you encounter any specific challenges related to JavaScript interactions during the extraction process, feel free to ask for assistance!

I've been looking for a tool to extract images for my art research project. Can Octoparse handle websites with images protected by watermarks or overlayed with copyright information?
George Forrest
Hi Emily, Octoparse can handle websites with images protected by watermarks or overlayed with copyright information. Octoparse focuses on extracting images as they are presented on the webpage, including any watermarked or copyrighted images. However, it's essential to consider copyright laws and the terms of use of the websites you extract images from. Octoparse's primary goal is to facilitate extraction based on publicly accessible website content, and it's the user's responsibility to ensure that they comply with applicable copyright regulations. If you have any further questions or need assistance specific to extracting images with watermarks or copyright overlays, feel free to ask!

Octoparse seems like a versatile tool for image extraction. Can I extract images from multiple websites simultaneously?

Hi David, Octoparse supports concurrent extraction, allowing you to extract images from multiple websites simultaneously. Octoparse's built-in parallel extraction capabilities enhance efficiency and can significantly reduce the overall extraction time, especially when dealing with multiple websites. As long as your system resources and network conditions allow, you can extract images from multiple websites simultaneously using Octoparse. If you need any guidance on optimizing parallel extraction or have specific challenges with concurrent extraction, feel free to ask!
Sophie Walker
I've used Octoparse for data extraction, but I'm interested in exploring its image extraction capabilities. Can I upgrade my existing Octoparse license to include image extraction?
George Forrest
Hi Sophie, if you already have an existing Octoparse license for data extraction, you should be able to utilize the same license for image extraction as well. Octoparse offers comprehensive functionality for both data extraction and image extraction within the same tool. There's no need to upgrade your license separately to access image extraction capabilities. If you have any specific concerns related to licensing or need assistance in utilizing Octoparse for image extraction with your existing license, feel free to ask!
