Question

私はPythonスパイダーに次の問題があります。スパイダーはすべての正しいデータを抽出しますが、すべてのデータをまとめています。ウェブサイト。

ここにスパイダーのコードです。

import scrapy 
from scrapy import * 
from auInd.items import AuindItem 

class auInSpider(scrapy.Spider): 
    name = "auiS" 
    start_urls = ["https://au.indeed.com/jobs?as_and=&as_phr=&as_any=&as_not=&as_ttl=&as_cmp=&jt=all&st=&salary=&radius=0&l=Australia&fromage=any&limit=50&sort=&psf=advsrch", 
    ] 

    def parse(self, response): 
     yield { 
      'title':response.xpath('//h2[@class="jobtitle"]//text()').extract(), 
      'company': response.xpath('//span[@class="company"]//text()').extract(), 
      'location': response.xpath('//span[@itemprop="jobLocation"]//text()').extract(), 
      'sumary': response.xpath('//span[@class="summary"]//text()').extract(), 
      'jobType': response.xpath('//td[@class="snip"]/text()').extract(), 
      'date': response.xpath('//span[@class="date"]/text()').extract(), 
      'salary': response.xpath('//nobr/text()').extract() 
     } 

そして、これが.json
