美麗的湯未能解析

Question

我想抓取一個頁面，並從即時抓取頁面獲得電話號碼，是的，我已經參考了beautifulsoup文檔，只需要知道如何抓取頁面並從該頁面獲取信息，有什麼建議麼 ？

這裏是代碼

Main.py

#!/usr/bin/env python 
# -*- coding: utf-8 -*- 

import requests 
import urllib 
from bs4 import BeautifulSoup 


glimit = 100 


def my_spider(max_pages): 
    page = 2 
    while page <= max_pages: 
     url = 'http://www.bbb.org/search/?type=name&input=constrution&location=Austin%2c+TX&filter=combined&accredited=&radius=5000&country=USA&language=en&codeType=YPPA' 
     url_2 = url + '&page='+ str(page) +'&source=bbbse' 
     source_code = requests.get(url_2) 
     plain_text = source_code.text 
     soup = BeautifulSoup(plain_text, "html5lib") 
     limit = glimit 
     li = soup.find('h4', {'class': 'hcolor'}) 
     children = li.find_all("a") 
     for result in children: 
      href = "http://www.bbb.org" + result.get('href') 
      owl = (result.string) 
      print owl 
      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, "html5lib") 
    limit = glimit 
    mysoup = soup.findAll('h3',{'class': 'address__heading' })[:limit] 
    mysoup2 = mysoup.find_all("a") 
    for item in mysoup2: 
     href = "http://www.bbb.org" + item.get('href') 
     print (item.string) 


my_spider(2) 

，這裏是錯誤

Answer 1

你在你的代碼的各種問題。 1）你不需要有href = "http://www.bbb.org" +。刪除"http://www.bbb.org"，因爲鏈接已經有主持人。

2）

mysoup = soup.findAll('h3',{'class': 'address__heading' })[:limit] 
mysoup2 = mysoup.find_all("a") 

你正在努力尋找在列表a標籤。您必須迭代mysoup或使用find而不是findAll。

我已更新您的代碼。找到它here。
