Question

我正在尝试从以下网页获取所有事件以及这些事件的其他元数据：https://alando-palais.de/events

我的问题是，result（html）不包含我要查找的信息。我想，它们被“隐藏”在某些php脚本后面。该网址：“ https://alando-palais.de/wp/wp-admin/admin-ajax.php”

关于如何等待页面完全加载的任何想法，或者我必须使用哪种方法来获取事件信息？

这是我现在的脚本：-）：

from bs4 import BeautifulSoup
from urllib.request import urlopen, urljoin
from urllib.parse import urlparse
import re
import requests

if __name__ == '__main__':
    target_url = 'https://alando-palais.de/events'
    #target_url = 'https://alando-palais.de/wp/wp-admin/admin-ajax.php'

    soup = BeautifulSoup(requests.get(target_url).text, 'html.parser')
    print(soup)

    links = soup.find_all('a', href=True)
    for x,link in enumerate(links):
        print(x, link['href'])


#    for image in images:
#        print(urljoin(target_url, image))

预期的输出将类似于：

日期：08.03.2019
标题：顶楼俱乐部特惠：Maiwai＆Friends
img： https://alando-palais.de/wp/wp-content/uploads/2019/02/0803_MaiwaiFriends-500x281.jpg”

这与结果无关：

<div class="vc_gitem-zone vc_gitem-zone-b vc_custom_1547045488900 originalbild vc-gitem-zone-height-mode-auto vc_gitem-is-link" style="background-image: url(https://alando-palais.de/wp/wp-content/uploads/2019/02/0803_MaiwaiFriends-500x281.jpg) !important;">
    <a href="https://alando-palais.de/event/penthouse-club-special-maiwai-friends" title="Penthouse Club Special: Maiwai &#038; Friends" class="vc_gitem-link vc-zone-link"></a>    <img src="https://alando-palais.de/wp/wp-content/uploads/2019/02/0803_MaiwaiFriends-500x281.jpg" class="vc_gitem-zone-img" alt="">  <div class="vc_gitem-zone-mini">
        <div class="vc_gitem_row vc_row vc_gitem-row-position-top"><div class="vc_col-sm-6 vc_gitem-col vc_gitem-col-align-left">   <div class="vc_gitem-post-meta-field-Datum eventdatum vc_gitem-align-left"> 08.03.2019
    </div>

Answer 1

您可以模仿页面上的xhr帖子

from bs4 import BeautifulSoup
import requests
import pandas as pd

url = 'https://alando-palais.de/wp/wp-admin/admin-ajax.php'

data = {

  'action': 'vc_get_vc_grid_data',
  'vc_action': 'vc_get_vc_grid_data',
  'tag': 'vc_basic_grid',
  'data[visible_pages]' : 5,
  'data[page_id]' : 30,
  'data[style]' : 'all',
  'data[action]' : 'vc_get_vc_grid_data',
  'data[shortcode_id]' : '1551112413477-5fbaaae1-0622-2',
  'data[tag]' : 'vc_basic_grid',
  'vc_post_id' : '30',
  '_vcnonce' : 'cc8cc954a4'  

}

res = requests.post(url, data = data)
soup = BeautifulSoup(res.content, 'lxml')
dates = [item.text.strip() for item in soup.select('.vc_gitem-zone[style*="https://alando-palais.de"]')]
textInfo = [item for item in soup.select('.vc_gitem-link')][::2]
imageLinks = [item['src'].strip() for item in soup.select('img')]
titles = []
links = []
for item in textInfo:
    titles.append(item['title'])
    links.append(item['href'])
results = pd.DataFrame(list(zip(titles, dates, links, imageLinks)),columns = ['title', 'date', 'link', 'imageLink'])
print(results)

或者使用硒：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import pandas as pd

url = 'https://alando-palais.de/events#'
driver = webdriver.Chrome()
driver.get(url)

dates = [item.text.strip() for item in WebDriverWait(driver,10).until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, ".vc_gitem-zone[style*='https://alando-palais.de']"))) if len(item.text)]
textInfo = [item for item in driver.find_elements_by_css_selector('.vc_gitem-link')][::2]
textInfo = textInfo[: int(len(textInfo) / 2)]
imageLinks = [item.get_attribute('src').strip() for item in driver.find_elements_by_css_selector('a + img')][::2]
titles = []
links = []

for item in textInfo:
    titles.append(item.get_attribute('title'))
    links.append(item.get_attribute('href'))
results = pd.DataFrame(list(zip(titles, dates, links, imageLinks)),columns = ['title', 'date', 'link', 'imageLink'])

print(results)

driver.quit()

Answer 2

我最好建议您selenium绕过所有服务器限制。

已编辑

from selenium import webdriver

driver = webdriver.Firefox()
driver.get("https://alando-palais.de/events")
elems = driver.find_elements_by_xpath("//a[@href]")
for elem in elems:
    print elem.get_attribute("href")
