Empty result file using scrapy-CodePudding

just started learning python so sorry if this is a stupid question!

I'm trying to scrape real estate data from this website: https://www.immoscout24.ch/de/buero-gewerbe-industrie/mieten/ort-zuerich?pn=2&r=10 using scrapy.

Ideally, in the end I'd get a file containing all available real estate offers and their respective address, price, area in m2, and other details (e.g. connection to public transport).

I built a test spider with scrapy but it always returns an empty file. I tried a whole bunch of different xpaths but can't get it to work. Can anyone help? Here's my code:

import scrapy

class GetdataSpider(scrapy.Spider):
  name = 'getdata' 
  allowed_domains = ['immoscout24.ch']
  start_urls = ['https://www.immoscout24.ch/de/buero-gewerbe-industrie/mieten/ort-zuerich?r=10',
  'https://www.immoscout24.ch/de/buero-gewerbe-industrie/mieten/ort-zuerich?pn=2&r=10',
  'https://www.immoscout24.ch/de/buero-gewerbe-industrie/mieten/ort-zuerich?pn=3&r=10',
  'https://www.immoscout24.ch/de/buero-gewerbe-industrie/mieten/ort-zuerich?pn=4&r=10',
  'https://www.immoscout24.ch/de/buero-gewerbe-industrie/mieten/ort-zuerich?pn=5&r=10']

  def parse(self, response):

    single_offer = response.xpath('//*[@]')


    for offer in single_offer: 
        offer_price = offer.xpath('.//*[@]/text()').extract()
        offer_address = offer.xpath('.//*[@]/text()').extract_first()

        yield {'Price': offer_price,
                'Address': offer_address}

CodePudding user response：

First all of , You need to add your real user agent . I injected user-agent in settings.py file. I also have corrected the xpath selection and made pagination in start_urls which type of next page pagination is 2 time fister than other types.This is the woeking example.

import scrapy
class GetdataSpider(scrapy.Spider):
    name = 'getdata'
    allowed_domains = ['immoscout24.ch']
    start_urls = ['https://www.immoscout24.ch/de/buero-gewerbe-industrie/mieten/ort-zuerich?pn='  str(x) '&r=10' for x in range(1,5)]
                

    def parse(self, response):

        single_offer = response.xpath('//*[@]')

        for offer in single_offer:
            name = offer.xpath('.//*[@]/span/text()').extract_first()
            offer_address = offer.xpath('.//*[@]/text()').extract_first()

            yield {'title': name,
                   'Address': offer_address}

Output:
