Con el web scraping, la recuperación de grandes cantidades de datos útiles de sitios web está a solo un clic de distancia. Web scraping es una técnica utilizada por webmasters y marketers para extraer textos, imágenes y documentos de la red.

Octoparse

Hoy en día, raspar imágenes desde sitios de carga estáticos y de JavaScript se ha convertido en una tarea diaria para ejecutar. Puede usar Octoparse para extraer imágenes de destino como la URL de la ubicación de la imagen en una página web. En esta guía, aprenderá a usar la herramienta de raspado "descargar desde URL" para recuperar grandes cantidades de imágenes de sitios web.

Algunas herramientas de raspado web se han presentado para actividades de raspado web. Las herramientas de raspado web están diseñadas para raspar los sitios de carga estáticos y de JavaScript. Si no eres un programador, no tienes que entrar en pánico. La extracción de imágenes de sitios usando Octoparse es tan simple como ABC.

La elección de la herramienta de raspado web para trabajar depende de sus proyectos. Algunas de las herramientas están diseñadas para extraer grandes cantidades de imágenes al mismo tiempo, mientras que otras se ajustan a una única fuente por solicitud. Tenga en cuenta que la mayoría de los sitios web de comercio electrónico restringen a los usuarios de los sitios web. En tal caso, se recomienda verificar el archivo de configuración robots.txt de los sitios web para ver los permisos.

¿Cómo extraer imágenes de sitios web?

  • Usando su navegador incorporado, abra la página web que comprende las imágenes que se recuperarán.
  • Configure la paginación para la extracción para obtener todas las URL de sus imágenes de destino.
  • Seleccione en el icono "Crear una lista de elementos" en la esquina superior izquierda de su navegador y edite la lista compilada.
  • Haga clic en "Loop" para procesar su lista compilada.
  • Comience a extraer todas las URL de las imágenes haciendo clic en "Extraer texto". Para obtener resultados confiables, la dirección de la imagen debe estar en etiqueta de imagen principal. Recuerde localizar la etiqueta de imagen adecuada antes de comenzar a extraer todas las imágenes de una página web.
  • Para ejecutar el proceso de extracción en su máquina local, haga clic en "Extracción local". Sin embargo, ejecute este paso una vez que haya terminado de configurar todas las reglas para extraer imágenes de un sitio web.
  • Después de obtener las URL de todas las imágenes en una página web, exporte los datos recortados a un archivo local o a un formato de base de datos. 

Las URL raspadas de todas las imágenes se pueden exportar en CouchDB o en Microsoft Excel. La elección de la base de datos a considerar depende de la cantidad de imágenes que se exportarán. Para finalizar el proceso de extracción de imágenes, utilice Pestaña de extensión de Google Chrome y haga clic en "guardar" para descargar todas las imágenes. Ingrese los enlaces de descarga obtenidos en nuestra consulta de búsqueda del navegador para comenzar.

Copie y pegue las URL de las imágenes en su cuadro de texto y haga clic en el botón "Descargar" para guardar las imágenes en su PC. La extracción de imágenes de sitios web usando Octoparse está a solo un clic de distancia. No permita que los conocimientos de programación pongan en peligro sus proyectos de eliminación de imágenes. Descargue y guarde imágenes de sitios de carga estáticos y de JavaScript con facilidad utilizando los tutoriales de Octoparse.
