+
+ + +# 📜 Introdução ao Scrapy e tutorias de instalação + +## O que é o Scrapy? 🤔 +O Scrapy é um framework de web scraping de código aberto em Python usado para extrair informações de sites da web de maneira automatizada. Web scraping é o processo de coletar dados de páginas da web de forma programática, em vez de manualmente, o que é útil para várias finalidades, como coletar dados para análise, pesquisa, mineração de dados, entre outras. + +O Scrapy fornece uma estrutura robusta e flexível para desenvolver [spiders](#nossa-primeira-spyder-🕷️), que são programas que navegam na web, fazem solicitações HTTP para páginas da web, extraem dados de interesse e armazenam esses dados em um formato estruturado, como JSON, CSV ou em um banco de dados. Além disso, o Scrapy lida com tarefas como gerenciamento de cookies, tratamento de redirecionamentos, paralelismo de solicitações e muito mais. + +**Clique** 👉 [**aqui**](https://github.com/unb-mds/2023-2-Squad04/blob/main/prototipos/tutorial_spyder/) **e tenha acesso ao nosso prototipo** + +## Instalação do Scrapy 👨‍🔧 +Para começar a usar o Scrapy, siga estas etapas para a instalação:
+**⚠️ Certifique-se de que você tenha o Python instalado em seu sistema. O Scrapy requer Python 3.8+** +1. Verificando a versão do python: `python --version` +2. Instalando o scrapy: + - Se você estiver usando Anaconda ou Miniconda, você pode instalar a partir do canal conda-forge, que possui pacotes atualizados para Linux, Windows e macOS: `conda install -c conda-forge scrapy` + - Como alternativa, se você já estiver familiarizado com a instalação de pacotes Python, você pode instalar o Scrapy e suas dependências do PyPI com: `pip install scrapy` + - Verifique a instalação: `scrapy --version`
+ + 3. ⚠️ **Em caso de erros, crie um Ambiente Virtual (Recomendado para evitar conflitos entre pacotes instalados no sistema):** + - Primeiro, crie um ambiente virtual: `python3 -m venv meuambiente` + - Ative o ambiente virtual: `source meuambiente/bin/activate` + - Instale o scrapy: `pip install scrapy` + - Para sair do ambiente virtual, basta digitar o seguinte comando: `deactivate` + + +## Exemplo de utilização do Scrapy 🧐 +Vamos raspar [quotes.toscrape.com](quotes.toscrape.com), um site que lista citações de autores famosos. + +### Nossa primeira Spyder 🕷️ + +Spiders são classes que você define e que o Scrapy usa para raspar informações de um site (ou de um grupo de sites). + +#### Criando um projeto + +Antes de começar a fazer web scraping, você precisará configurar um novo projeto Scrapy. Acesse um diretório onde você deseja armazenar seu código e execute: +`scrapy startproject tutorial` + +Isso criará um diretório com o seguinte conteúdo: +``` +tutorial/ + scrapy.cfg # arquivo de configuração para implantação + + tutorial/ # módulo Python do projeto, você importará seu código a partir daqui + __init__.py + + items.py # arquivo de definição de itens do projeto + + middlewares.py # arquivo de middlewares do projeto + + pipelines.py # arquivo de pipelines do projeto + + settings.py # arquivo de configurações do projeto + + spiders/ # um diretório onde você colocará suas spiders posteriormente + __init__.py + +``` + +Este é o código para a nossa primeira Spider. + +```python +from pathlib import Path + +import scrapy + +class QuotesSpider(scrapy.Spider): + name = "quotes" + + def start_requests(self): + urls = [ + "https://quotes.toscrape.com/page/1/", + "https://quotes.toscrape.com/page/2/", + ] + for url in urls: + yield scrapy.Request(url=url, callback=self.parse) + + def parse(self, response): + page = response.url.split("/")[-2] + filename = f"quotes-{page}.html" + Path(filename).write_bytes(response.body) + self.log(f"Saved file {filename}") +``` + +Como você pode ver, nossa Spider é uma subclasse de scrapy.Spider e define alguns atributos e métodos: + +- **name:** identifica a Spider. Ele deve ser exclusivo dentro de um projeto, ou seja, você não pode definir o mesmo nome para diferentes Spiders. + +- **start_requests():** deve retornar um iterável de Requests (você pode retornar uma lista de solicitações ou escrever uma função geradora) a partir das quais a Spider começará a rastrear. Solicitações subsequentes serão geradas sucessivamente a partir dessas solicitações iniciais. + +- **parse():** um método que será chamado para lidar com a resposta baixada para cada uma das solicitações feitas. O parâmetro de resposta é uma instância de TextResponse que contém o conteúdo da página e possui métodos adicionais úteis para lidar com ele. + +- O método **parse()** geralmente analisa a resposta, extrai os dados raspados como dicionários e também encontra novas URLs para seguir, criando novas solicitações () a partir delas. + +#### Como executar nossa spyder 💻 +Para colocar nossa spider para trabalhar, vá para o diretório de nível superior do projeto e execute:
+`scrapy crawl quotes` + +Este comando executa a spider com o nome que acabamos de adicionar, que enviará algumas solicitações para o domínio. Você receberá uma saída semelhante a esta: + +``` +... (omitted for brevity) +2016-12-16 21:24:05 [scrapy.core.engine] INFO: Spider opened +2016-12-16 21:24:05 [scrapy.extensions.logstats] INFO: Crawled 0 pages (at 0 pages/min), scraped 0 items (at 0 items/min) +2016-12-16 21:24:05 [scrapy.extensions.telnet] DEBUG: Telnet console listening on 127.0.0.1:6023 +2016-12-16 21:24:05 [scrapy.core.engine] DEBUG: Crawled (404) (referer: None) +2016-12-16 21:24:05 [scrapy.core.engine] DEBUG: Crawled (200) (referer: None) +2016-12-16 21:24:05 [scrapy.core.engine] DEBUG: Crawled (200) (referer: None) +2016-12-16 21:24:05 [quotes] DEBUG: Saved file quotes-1.html +2016-12-16 21:24:05 [quotes] DEBUG: Saved file quotes-2.html +2016-12-16 21:24:05 [scrapy.core.engine] INFO: Closing spider (finished) +... +``` + +Agora, verifique os arquivos no diretório atual. Você deve notar que dois novos arquivos foram criados: **quotes-1.html** e **quotes-2.html**, com o conteúdo correspondente às respectivas URLs, conforme nosso método instrui. + +#### O que aconteceu nos bastidores? 🤔 + +O Scrapy agendou os objetos retornados pelo método da Spider. Ao receber uma resposta para cada um deles, ele cria objetos de Resposta e chama o método de retorno de chamada associado à solicitação (neste caso, o método "parse"), passando a resposta como argumento. + +#### Raspando apenas os dados e salvando em um .json 💾 +O código abaixo é um exemplo de uma spider que raspa dados das páginas, em vez de salvar o HTML como fazia a do exemplo anterior. + +**Clique** 👉 [**aqui**](https://github.com/unb-mds/2023-2-Squad04/blob/main/prototipos/tutorial_spyder/) **e tenha acesso ao nosso prototipo** + +``` +import scrapy + +class QuotesSpider(scrapy.Spider): + # Nome do spider + name = "quotes" + + # URLs iniciais a serem raspadas + start_urls = [ + "https://quotes.toscrape.com/page/1/", + "https://quotes.toscrape.com/page/2/", + ] + + # Função que é chamada para processar cada página + def parse(self, response): + # Loop através de cada elemento 'div.quote' na página + for quote in response.css("div.quote"): + # Extrai o texto da citação usando o seletor CSS + text = quote.css("span.text::text").get() + # Extrai o autor da citação usando o seletor CSS + author = quote.css("span small::text").get() + # Extrai todas as tags da citação usando o seletor CSS + tags = quote.css("div.tags a.tag::text").getall() + + # Cria um dicionário com os dados extraídos + quote_data = { + "text": text, + "author": author, + "tags": tags, + } + + # Retorna o dicionário como resultado do processamento da página + yield quote_data + + # Verifica se há uma próxima página + next_page = response.css("li.next a::attr(href)").get() + if next_page is not None: + # Se houver uma próxima página, segue o link e chama 'parse' novamente + yield response.follow(next_page, self.parse) + +``` +Você pode armazenar os dados extraídos em um formato de sua escolha, como JSON, CSV ou em um banco de dados. Para salvar os dados em um arquivo JSON, você pode usar o seguinte comando: `scrapy crawl livros -o livros.json` + +# 🕵️ Para saber mais... +Esse tutorial se baseou na documentação oficial do scrapy, se você quiser saber mais a fundo sobre todas as funcionalidades disponíveis da ferramenta, clique 👉 [aqui](https://docs.scrapy.org/en/latest/index.html) e acesse a documentação completa. + + +

+ “This life is what you make it. No matter what, you're going to mess up sometimes, it's a universal truth. But the good part is you get to decide how you're going to mess it up. Girls will be your friends - they'll act like it anyway. But just remember, some come, some go. The ones that stay with you through everything - they're your true best friends. Don't let go of them. Also remember, sisters make the best friends in the world. As for lovers, well, they'll come and go too. And baby, I hate to say it, most of them - actually pretty much all of them are going to break your heart, but you can't give up because if you give up, you'll never find your soulmate. You'll never find that half who makes you whole and that goes for everything. Just because you fail once, doesn't mean you're gonna fail at everything. Keep trying, hold on, and always, always, always believe in yourself, because if you don't, then who will, sweetie? So keep your head high, keep your chin up, and most importantly, keep smiling, because life's a beautiful thing and there's so much to smile about.” + by + (about) + +

She may not be thinking about you every second of the day, but she will give you a part of her that she knows you can break—her heart. So don't hurt her, don't change her, don't analyze and don't expect more than she can give.
