Shop::Amazon - scraper de produtos Amazon

Visão geral do scraper​

Ao utilizar o scraper de produtos da amazon, você pode obter todos os dados da ficha do produto, coletar uma base de links de produtos, monitorar a dinâmica de preços e frete, coletar avaliações de classificação e o número de comentários do produto, coletar imagens dos produtos e obter uma lista de lojas.

A funcionalidade do A-Parser permite salvar as configurações de extração de dados para uso futuro (presets), definir agendamentos de extração de dados e muito mais. Você pode usar a multiplicação automática de consultas, substituição de subconsultas a partir de arquivos, combinação de caracteres alfanuméricos e listas para obter o máximo possível de resultados.

Tarefa em execução

Dados coletados​

Dados coletados
  • Nome do produto
  • Link do produto
  • Imagem do produto
  • Preço e preço sem desconto
  • Classificação, número de comentários
  • Quantidade de vendas e vendedores
  • Vendedor
  • Informações adicionais (Bestseller, Sponsored)

Casos de uso​

  • Coleta de links de produtos
  • Avaliação da popularidade dos produtos
  • Monitoramento da dinâmica de preços

Consultas​

Como consultas, é necessário indicar os nomes dos produtos, exatamente como se fossem digitados diretamente no formulário de busca da Amazon, por exemplo:

iphone 11pro max
Mouse Bluetooth sem fio, mouse gamer doméstico
Cartão de memória Micro Sd Sandisk, cartão Micro Sd Class10 TF
AMD Ryzen R3 2200U

Substituições de consultas​

Você pode usar macros integradas para multiplicar consultas, por exemplo, se quisermos obter uma base de produtos muito grande por marcas,

philips
sony
xiaomi
samsung

No formato de consultas, indicaremos a iteração de caracteres de a até zzzz, este método permite rotacionar ao máximo os resultados de busca e obter muitos novos resultados únicos:

$query {az:a:zzzz}

Esta macro criará 475254 consultas adicionais para cada consulta de busca inicial, o que resultará em um total de 4 x 475254 = 1901016 consultas de busca, um número impressionante, mas isso não é problema para o A-Parser. Com uma velocidade de 2000 consultas por minuto, essa tarefa será processada em apenas 16 horas.

Opções de exibição de resultados​

O A-Parser suporta formatação flexível de resultados graças ao motor de modelos integrado Template Toolkit, o que permite exibir resultados em formato livre, bem como estruturado, como CSV ou JSON.
