Semalt: Como usar jQuery.Ajax em uma extensão do Google Chrome

Feb 06, 2018

Hoje em dia, os raspadores de web usam ferramentas de raspagem de web de alta classificação para extrair dados úteis da web páginas em formatos utilizáveis. Essas ferramentas de raspagem na Web compreendem recursos pré-embalados que permitem criar um plano efetivo (sitemap) sobre como um site deve ser navegado e raspado.

Por que jQuery.ajax?

A extração de dados da Web é denominada como a solução definitiva para extrair informações da web automaticamente. Se você está trabalhando na extração de informações de sites dinâmicos, a primeira coisa que você precisa fazer é verificar se o site é composto de uma interface oficial de programação de aplicativos (API) ou não.

Normalmente, todos os dados que podem ser vistos em sites e páginas web de comércio eletrônico podem ser extraídos automaticamente. Na indústria atual de marketing on-line, os sites são de maior importância em comparação com as APIs. É aqui que jQuery.ajax entra. Os proprietários do site se concentram em melhorar o engajamento estimulado com potenciais visitantes do que manter seus feeds de dados.

O JavaScript assíncrono e XML (AJAX) é uma tecnologia heurística que ajuda os comerciantes a carregar dados do servidor primário atualizando a página do navegador. Com o AJAX, você pode carregar os dados de destino no fundo de sua máquina e exibi-lo em uma página sem recarregar a página inteira.

Usando jQuery.ajax no plugin do Chrome

O jQuery é uma extensão do Ajax Chrome, que é amplamente utilizada no setor de marketing para enviar solicitações de raspagem na web. Aplicativos como o Google Maps, o Facebook e o Gmail usam toda a execução de suas tarefas. Aqui estão os parâmetros comuns que especificam os valores usados em uma solicitação Ajax:

Async - Este valor da extensão Ajax Chrome indica se o número total de pedidos enviados deve ser executado de forma assíncrona ou não;
Cache - O valor do cache indica se o Google Chrome deve armazenar em cache as páginas da web solicitadas. Observe que a função "Antes de Enviar" é executada antes de uma solicitação ser enviada para as páginas da Web de destino;
Contexto - Esta extensão Ajax Chrome especifica o valor primário de todas as funções de retorno de chamada baseadas no Ajax;
ProcessData - W Quando ele vem ao uso de AJAX, esse valor especifica se os dados enviados com solicitações devem ser totalmente transformados em uma string de consulta ou não. Observe que o parâmetro URL necessário especifica o URL que você prefere carregar.

O que você precisa saber sobre jQuery e AJAX

A extração de dados de sites desenvolvidos usando tecnologia heurística pode ser um pouco complicada. Com as técnicas jQuery AJAX adequadas, você pode solicitar rapidamente JSON, XML ou HTML a partir de um servidor localizado remotamente usando HTTP Post e HTTP Get. Note que jQuery oferece uma grande quantidade de funcionalidades AJAX.

Navegadores diferentes contém sintaxe diferente para cada implementação AJAX. Você, portanto, tem que escrever vários códigos para navegadores diferentes, como Mozilla, Google Chrome e Internet Explorer. Felizmente, você pode carregar dados externos diretamente nos elementos HTML previamente selecionados da página da Web de destino.

Na maioria dos casos, jQuery usa métodos "GET" e "POST" para solicitar dados de recursos especificados e enviar informações para serem processadas em recursos especificados. Por padrão, todas as solicitações são enviadas de forma assíncrona (True). Para usar as aplicações simultâneas, defina a opção assíncrona como falsa. Use a extensão jQuery.Ajax Chrome para facilitar sua campanha de raspagem na web e obter dados precisos e estruturados.
