[PYTHON] Einführung in Scrapy (4)

Einführung in Scrapy (4)

Einführung

Einführung in Scrapy (1) Einführung in Scrapy (2) Einführung in Scrapy (3)

Im vorherigen Artikel habe ich versucht, Dateien mit Scrapy herunterzuladen. Dieses Mal werde ich Ihnen zeigen, wie Sie Argumente über die Befehlszeile an Spider übergeben.

Eine Spinne erstellen

Dieses Mal werden wir eine Spinne erstellen, um den Inhalt der Kategorieseite von Qiitas Adventskalender zu erhalten. In Spider empfängt es die Zielkategorie als Befehlszeilenargument, generiert dynamisch die Ziel-URL und lädt den Inhalt der Seite herunter.

qiita_spider.py


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


import scrapy


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

    def start_requests(self):

        #URL, die gecrawlt werden soll
        url = 'http://qiita.com/advent-calendar/2016/categories/'

        #Über die Befehlszeile übergebene Argumente können standardmäßig als Spider-Attribute abgerufen werden.
        #In diesem Fall selbst.Sie können den Wert des Arguments in Kategorien abrufen.
        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}

Wie man Argumente übergibt

Mit der Option -a können Sie Argumente an Befehle übergeben, die mit Scrapy geliefert werden.

-a categories=programming_languages

Wenn Sie mehrere Argumente übergeben möchten, schreiben Sie wie folgt.

-a offset=0 -a limit=100

Befehlsausführung

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

Wenn Sie den Befehl ausführen, wird das Protokoll auf der Konsole angezeigt. Wie beim letzten Mal erläutert, werden im Protokoll Informationen wie die abgerufene URL, der Status, die Anzahl der Bytes und die Zusammenfassung angezeigt.
