BeautifulSoup 没有获取所有数据,只有一些

BeautifulSoup is not getting all data, only some

import requests
from bs4 import BeautifulSoup


def trade_spider(max_pages):
page = 0
while page <= max_pages:
    url = 'http://orangecounty.craigslist.org/search/foa?s=' + str(page * 100)
    source_code = requests.get(url)
    plain_text = source_code.text
    soup = BeautifulSoup(plain_text)
    for link in soup.findAll('a', {'class':'hdrlnk'}):
        href = 'http://orangecounty.craigslist.org/' + link.get('href')
        title = link.string
        print title
        #print href
        get_single_item_data(href)
    page += 1

def get_single_item_data(item_url):
    source_code = requests.get(item_url)
    plain_text = source_code.text
    soup = BeautifulSoup(plain_text)
    for item_name in soup.findAll('section', {'id':'postingbody'}):
        print item_name.string

我正在尝试抓取 craigslist(练习),尤其是 http://orangecounty.craigslist.org/search/foa?s=0。我现在将其设置为打印条目的标题和条目的描述。问题是,虽然标题为列出的每个 object 都正确打印,但其中大多数的描述被列为 "None",即使有明确的描述。任何帮助,将不胜感激。谢谢

而不是获取发帖正文的 .stringget the text(为我工作):

item_name.get_text(strip=True)

附带说明一下,您的脚本有一个阻塞 "nature",您可以通过切换到 Scrapy web-scraping framework 来显着加快速度。

你快到了。只需将 item_name.string 更改为 item_name.text
