Semalt Expert elabora herramientas de extracción de datos en el sitio web

Dec 01, 2017

El desguace web implica la recopilación de datos de un sitio web utilizando un rastreador web. Las personas utilizan las herramientas de extracción de datos del sitio web para obtener información valiosa de un sitio web que puede estar disponible para su exportación a otra unidad de almacenamiento local o una base de datos remota. Un software web scraper es una herramienta que se puede usar para rastrear y recolectar información del sitio web, como categorías de productos, todo el sitio web (o partes), contenido e imágenes. Puede obtener cualquier contenido de sitio web desde otro sitio sin una API oficial para tratar con su base de datos.

En este artículo de SEO, existen los principios básicos con los que operan estas herramientas de extracción de datos de sitios web. Puede aprender la forma en que la araña lleva a cabo el proceso de rastreo para guardar los datos de un sitio web de una manera estructurada para la recopilación de datos del sitio web. Consideraremos la herramienta de extracción de datos del sitio web BrickSet. Este dominio es un sitio web basado en la comunidad que contiene mucha información sobre los juegos de LEGO. Debería poder hacer una herramienta funcional de extracción de Python que pueda viajar al sitio web de BrickSet y guardar la información como conjuntos de datos en su pantalla..Este raspador web es ampliable y puede incorporar cambios futuros en su funcionamiento.

Necesidades

Para crear un scrapper web de Python, necesita un entorno de desarrollo local para Python 3. Este entorno de ejecución es una API de Python o un Kit de desarrollo de software para hacer algunas de las partes esenciales de su software de rastreador web. Hay algunos pasos que uno puede seguir al hacer esta herramienta:

Creación de un raspador básico

En esta etapa, debe ser capaz de encontrar y descargar páginas web de un sitio web sistemáticamente. Desde aquí, puede tomar las páginas web y extraer la información que desee de ellas. Diferentes lenguajes de programación pueden lograr este efecto. Su rastreador debería poder indexar más de una página simultáneamente, así como también poder guardar los datos de varias maneras.

Necesitas tomar una clase Scrappy de tu araña. Por ejemplo, nuestro nombre de araña es brickset_spider. La salida debería verse así:

script de instalación de pip

Esta cadena de código es una Pip Python que puede aparecer similarmente en la cadena:

mkdir brickset-scraper

Esta cadena crea un nuevo directorio. Puede navegar hacia él y usar otros comandos como entrada táctil de la siguiente manera:

toca scraper.py
