Semalt: ¿Cómo raspar un sitio web con Ajax?

Ajax, también conocido como Asynchronous JavaScript and XML, es el conjunto de técnicas de desarrollo web. Se usa para crear diferentes aplicaciones web y software. Con Ajax, puede recuperar fácilmente datos de Internet y crear múltiples páginas web a la vez, sin interferir con el comportamiento y la visualización de sus páginas web existentes. Ajax le permite cambiar el contenido de un sitio dinámicamente sin necesidad de volver a cargar toda la página web. Las implementaciones modernas principalmente sustituyen a JSON por XML, pero Ajax no es una tecnología única. En cambio, es un grupo de tecnologías. CSS y HTML se usan individualmente o en combinación con otros lenguajes de marcado para diseñar diferentes páginas web.

Raspado de sitios web de Ajax:

Ajax no es una tecnología nueva y se utiliza para desarrollar diferentes sitios y mejorar el contenido de las páginas web existentes. Una variedad de bibliotecas JavaScript (incluido JQuery) se utilizan para ejecutar solicitudes Ajax. No es fácil robar un sitio web con JavaScript y Ajax, y no puede realizar esta tarea con un raspador de datos común. Sin embargo, las siguientes herramientas pueden facilitar su trabajo en cierta medida.

1. Octoparse

Octoparse es un extractor de datos poderoso e interactivo y un raspador web. Se usa principalmente para raspar sitios web de Ajax y JavaScript. También puede usar Octoparse para sitios de destino con cookies, ventanas emergentes y redirecciones. Octoparse es un software gratuito que viene con muchas opciones de raspado de datos y características de rastreo web. Puede usar el software para indexar sus páginas web y mejorar su clasificación en los motores de búsqueda. Una vez que un sitio de Ajax está completamente raspado, los datos se entregan en formatos Excel, XML, CSV y JSON. El precio de esta herramienta comienza desde $99, pero la versión gratuita es adecuada para curadores de contenido, no codificadores y pequeñas empresas.

2. PhantomJS

Al igual que Octoparse, PhantomJS se utiliza para raspar un sitio web de Ajax y JavaScript. Es principalmente un script de WebKit sin cabeza con JavaScript API. PhantomJS es mejor conocido por sus estándares web rápidos y confiables: selector de CSS, manejo de Canvas, SVG, JSON y DOM. Es la forma más adecuada de rozar el sitio web de Ajax y no necesita conocimientos de programación o codificación. Primero, tendrías que descargar PhantomJS. En el siguiente paso, deberá agregar un código especial a su sitio Ajax para raspar su contenido de manera cómoda y precisa. Puede usar este servicio con cualquier navegador web y es compatible con todos los sistemas operativos.

Conclusión:

Hay momentos en que tienes toneladas de sitios web de Ajax y quieres eliminar datos de todos ellos. En tales circunstancias, debe optar por un servicio más sofisticado y preciso, ya que ni PhantomJS ni Octoparse le proporcionarán resultados confiables. Ambos servicios son adecuados para tareas de raspado de datos de pequeño tamaño. Si tienes muchos sitios con Ajax, JavaScript, redirecciones y cookies, te sugerimos que import.io y Kimono Labs. Ambas herramientas tienen mejores características que Octoparse y PhantomJS. Alternativamente, las dos herramientas que discutimos anteriormente son buenas para tareas básicas de extracción de datos o extracción de web.
