Introduction à Scrapy (1) Introduction à Scrapy (2) Introduction à Scrapy (3)

Dans l'article précédent, j'ai essayé de télécharger des fichiers à l'aide de Scrapy. Cette fois, je vais vous montrer comment passer des arguments à Spider à partir de la ligne de commande.

Créer une araignée

Cette fois, nous allons créer une araignée pour obtenir le contenu de la page de catégorie du calendrier de l'Avent de Qiita. Dans Spider, il reçoit la catégorie cible en tant qu'argument de ligne de commande, génère dynamiquement l'URL cible et télécharge le contenu de la page.

qiita_spider.py


# -*- coding:utf-8 -*-


import scrapy


class QiitaSpider(scrapy.Spider):
    name = 'qiita_spider'

    def start_requests(self):

        #URL à explorer
        url = 'http://qiita.com/advent-calendar/2016/categories/'

        #Les arguments passés depuis la ligne de commande peuvent être obtenus en tant qu'attributs Spider par défaut.
        #Dans ce cas, soi.Vous pouvez obtenir la valeur de l'argument dans les catégories.
        categories = getattr(self, 'categories', None)
        if categories:
            url = '{0}{1}'.format(url, categories)

        yield scrapy.Request(url, self.parse)

    def parse(self, response):
        for title in response.css('.adventCalendarList_calendarTitle > a::text').extract():
            yield {'title': title}

Comment passer des arguments

Vous pouvez passer des arguments aux commandes fournies avec Scrapy en utilisant l'option -a.

-a categories=programming_languages

Si vous souhaitez transmettre plusieurs arguments, écrivez comme suit.

-a offset=0 -a limit=100

Exécution de la commande

scrapy crawl qiita_spider -a categories=programming_languages -o categories.json

Lorsque vous exécutez la commande, le journal s'affiche sur la console. Comme expliqué la dernière fois, le journal affiche des informations telles que l'URL en cours de récupération, l'état, le nombre d'octets et le résumé.
