Semalt Expert elabora sobre raspado de imágenes de Google

Buscar imágenes en Google es la forma más popular de obtener fondos de pantalla para su escritorio, imágenes para el proyecto, fotos para inspirarse, etc. Pero a veces lleva mucho tiempo revisarlos a todos y descargar cada imagen manualmente, por lo que debe acelerar y facilitar el proceso. Por supuesto, automatizar el proceso de descarga de imágenes de Google puede ser un pan comido si tiene un software especial como Google Image Downloader u otro, pero la mayoría de ellos no son gratuitos. Vamos a mostrarle algunas formas cómodas de raspar imágenes de Google con scripts.

PHP Script

PHP es un lenguaje de programación bastante útil para crear un web scraper. Con un simple script PHP, puede raspar imágenes de cualquier tema que necesite de Google. Puede establecer la solicitud y la profundidad del raspado. Todas las imágenes se descargarán a la carpeta que necesites en muy poco tiempo.

Existen muchos scripts PHP existentes para este propósito. Si no está familiarizado con la programación y no puede crearla por su cuenta, navegue por Internet y busque la que le resulte más cómoda.

Script de Python

Otra solución simple para raspar imágenes de Google es utilizar el script de Python. Puede encontrar diferentes guiones listos para usar en GitHub o escribirlos usted mismo. Python es un maestro en hacer su trabajo, y hay muchos bibliotecas que lo ayudarán a crear su propio raspador web.

La mayoría de los scripts raspadores en Python usan urllib y urllib2. Este módulo tiene sus propias funciones y clases que ayudan a trabajar con URLs: autenticación básica y resumida, redirecciones, cookies y mucho más. Por lo general, los scripts con urllib también usan la biblioteca BeautifulSoup, que es básicamente la herramienta más popular para copiar cualquier cosa y Google images no es una excepción.

Pero ten en cuenta que hay mucha información que no puedes get with urllib. Ahí es cuando puedes probar Selenium, un paquete que automatiza la interacción del navegador web con Python. El uso de Selenium siempre llega a la creación de un bot que realiza todo el trabajo manual con el navegador de manera automatizada. Y eso es exactamente lo que necesidad.

Otras opciones

En realidad, hay muchas maneras de eliminar las imágenes de Google, por lo que las opciones que se muestran en este artículo son solo ejemplos. El lenguaje de programación o software que elija para escribir un guión es solo cuestión de gustos. Es posible eliminar imágenes de Google con muchas más bibliotecas de Python que las que se enumeran aquí (Scrapy, JSON, etc.), también puede hacerlo con Java o JavaScript. ¡Sé creativo y encuentra tu propio camino!

Conclusión

Entonces, como puede ver, raspar las imágenes de Google no es tan difícil con las secuencias de comandos de Python o PHP. Ahora no tendrá problemas para descargar toneladas de imágenes de Google en solo unos minutos.

Puede usar cualquiera de los guiones de GitHub, pero recuerde que algunas imágenes están sujetas a la ley de derechos de autor y no puede usarlas pública o comercialmente sin el permiso del propietario.
