听起来好像你真正要找的数据可以通过主页面上的一些javascript调用的辅助URL访问。

虽然您可以尝试在服务器上运行javascript来处理这个问题，但一种更简单的方法可能是使用Firefox加载页面，并使用Charles或Firebug之类的工具来准确识别辅助URL。然后，您可以直接查询该URL以获得您感兴趣的数据。

你也可以使用webdriver执行javascript。

from selenium import webdriver

driver = webdriver.Firefox()
driver.get(url)
driver.execute_script('document.title')

或者将值存储在变量中

result = driver.execute_script('var text = document.title ; return text')

Playwright-Python

还有一种选择是剧作家- Python，它是微软剧作家(本身是受木偶大师影响的浏览器自动化库)到Python的移植。

下面是选择一个元素并抓取它的文本的最小示例:

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.launch()
    page = browser.new_page()
    page.goto("http://whatsmyuseragent.org/")
    ua = page.query_selector(".user-agent");
    print(ua.text_content())
    browser.close()

也许硒可以做到。

from selenium import webdriver
import time

driver = webdriver.Firefox()
driver.get(url)
time.sleep(5)
htmlSource = driver.page_source

这似乎是一个很好的解决方案，从一个伟大的博客文章

import sys  
from PyQt4.QtGui import *  
from PyQt4.QtCore import *  
from PyQt4.QtWebKit import *  
from lxml import html 

#Take this class for granted.Just use result of rendering.
class Render(QWebPage):  
  def __init__(self, url):  
    self.app = QApplication(sys.argv)  
    QWebPage.__init__(self)  
    self.loadFinished.connect(self._loadFinished)  
    self.mainFrame().load(QUrl(url))  
    self.app.exec_()  

  def _loadFinished(self, result):  
    self.frame = self.mainFrame()  
    self.app.quit()  

url = 'http://pycoders.com/archive/'  
r = Render(url)  
result = r.frame.toHtml()
# This step is important.Converting QString to Ascii for lxml to process

# The following returns an lxml element tree
archive_links = html.fromstring(str(result.toAscii()))
print archive_links

# The following returns an array containing the URLs
raw_links = archive_links.xpath('//div[@class="campaign"]/a/@href')
print raw_links

如前所述，Selenium是呈现JavaScript结果的好选择:

from selenium.webdriver import Firefox
from selenium.webdriver.firefox.options import Options

options = Options()
options.headless = True
browser = Firefox(executable_path="/usr/local/bin/geckodriver", options=options)

url = "https://www.example.com"
browser.get(url)

gazpacho是一个非常容易解析渲染html的库:

from gazpacho import Soup

soup = Soup(browser.page_source)
soup.find("a").attrs['href']
