Python+Scrapy+JSON+XPath：如何使用Scrapy获取JSON数据

Question

我知道如何用Scrapy获取HTML数据点的xpath。但是我必须从这个网站上获取这个页面的所有url（起始url），它们是用JSON格式编写的：

https://highape.com/bangalore/all-events

查看源：https://highape.com/bangalore/all-events

我通常是这样写的：

def parse(self, response):
      events = response.xpath('**What To Write Here?**').extract()

      for event in events:
          absolute_url = response.urljoin(event)
          yield Request(absolute_url, callback = self.parse_event)

请告诉我在这里写什么部分。在

Answer 1

What to write here?

events = response.xpath("//script[@type='application/ld+json']").extract()
events = json.loads(events[0])

Answer 2

查看url的页面源代码，然后复制第76-9045行并另存为数据.json在本地驱动器中，然后使用此代码。。。在

import json
from bs4 import BeautifulSoup
import requests
req = requests.get('https://highape.com/bangalore/all-events')
soup = BeautifulSoup(req.content, 'html.parser')
js = soup.find_all('script')[5].text
data = json.loads(js, strict=False)
for i in data:
    url = i['url']
    print(url)
    ##callback with scrapy
