尝试从网站抓取电子邮件地址

Question

我试着抓取这个网站：

www.united-church.ca/search/locator/all?keyw=&mission_units_ucc_ministry_type_advanced=10&locll=

我用Scrapy刮掉了它，但我不能刮掉电子邮件地址。有谁可以帮我？

到目前为止，我的代码如下：

# -*- coding: utf-8 -*-
import scrapy
from ..items import ChurchItem


class ChurchSpiderSpider(scrapy.Spider):
    name = 'church_spider'
    page_number = 1
    start_urls = ['https://www.united-church.ca/search/locator/all?keyw=&mission_units_ucc_ministry_type_advanced=10&locll=']

    def parse(self, response):
        items = ChurchItem()
        container = response.css(".icon-ministry")
        for t in container:
            church_name = t.css(".field-name-locator-ministry-title a::text").extract()
            church_phone = t.css(".field-name-field-phone::text").extract()
            church_address = t.css(".thoroughfare::text").extract()
            church_email = t.css(".field-name-field-mu-email span::text").extract()

            items["church_name"] = church_name
            items["church_phone"] = church_phone
            items["church_address"] = church_address
            items["church_email"] = church_email

            yield items

        # next_page = 'https://www.united-church.ca/search/locator/all?keyw=&mission_units_ucc_ministry_type_advanced=10&locll=&page=' + str(ChurchSpiderSpider.page_number)
        # if ChurchSpiderSpider.page_number <= 110:
        #     ChurchSpiderSpider.page_number += 1
        #     yield response.follow(next_page, callback=self.parse)

我已经找到了部分解决方案，但它仍然不完整。输出现在如下所示：

{'church_address': ['7763 Highway 21'],
 'church_email': ['herbklaehn', ' [at] ', 'gmail.com'],
 'church_name': ['Allenford United Church'],
 'church_phone': ['519-35-6232']}

如何用@替换[at]并将电子邮件地址合并为一个字符串？

Answer 1

使用美汤的

获取电子邮件的一种简单方法是使用class=field-name-field-mu-email'查找div，然后将奇怪的显示替换为适当的电子邮件格式。

例如：

from bs4 import BeautifulSoup
url = 'https://www.united-church.ca/search/locator/all?keyw=&mission_units_ucc_ministry_type_advanced=10&locll='

r = requests.get(url)
soup = BeautifulSoup(r.text, 'html.parser')

for div in soup.findAll('div', attrs={'class': 'field-name-field-mu-email'}):
    print (div.find('span').text.replace(' [at] ', '@'))

Answer 2

你可以尝试使用Selenium进行网络抓取，我尝试了这段代码，它给出了完美的结果。

from selenium import webdriver
from bs4 import BeautifulSoup


driver = webdriver.Chrome("chromedriver")
driver.get("https://www.united-church.ca/search/locator/all?keyw=&mission_units_ucc_ministry_type_advanced=10&locll=")

content = driver.page_source
soup = BeautifulSoup(content)

for all_emails in soup.find_all('a',class_="spamspan"):
    print(all_emails.text)

结果：

alpcharge@sasktel.net
guc-eug@bellnet.ca
pioneerpastoralcharge@gmail.com
acmeunitedchurch@gmail.com
cmcphers@lakeheadu.ca
mbm@kos.net
