如何通过Selenium检索页面源？

标签： python selenium selenium-webdriver iframe web-crawler

我想使用硒从该网站获取数据：

dropna

当我使用时：

driver.get(url_main)

driver.page_source

返回如下：

<!-- Vers: 80000 9 --><html xmlns="http://www.w3.org/1999/xhtml"><head>\n\t<title>The City of Coquitlam Property Inquiry System</title>\n</head>\n<frameset rows="100%, *" frameborder="0" framespacing="0">\n\t<frame src="default.cfm?autorefresh=yes" name="frame_map" id="frame_map" frameborder="0" scrolling="auto" noresize="" marginwidth="0" marginheight="0" />\n\t<frame src="nothing.cfm" name="frame_action" id="frame_action" frameborder="0" scrolling="no" marginwidth="0" marginheight="0" />\n</frameset>\n</html>

代替页面的完整html，我如何获得此网站的整个页面？

2 个答案:

答案 0 :(得分：2)

您可以使用以下代码：

driver.get("https://e-civic.coquitlam.ca/tempestprod/webinquiry/frames.cfm")  
driver.switch_to.frame("frame_map")
print(driver.page_source)

请注意，您的页面内容位于框架中。为了与 iframe / frame / frameset 中的element/elements进行交互，您必须将网络驱动程序的焦点切换到相应的框架。

希望这会有所帮助。

答案 1 :(得分：-1)

使用硒从网站https://e-civic.coquitlam.ca/tempestprod/webinquiry/frames.cfm中提取数据，您需要诱使 WebDriverWait 使预期的框架可用并切换到< / em>，则可以使用以下解决方案：

  • 代码块：

    from selenium import webdriver
from selenium.webdriver import Chrome
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

options = Options()
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\WebDrivers\ChromeDriver\chromedriver_win32\chromedriver.exe')    
driver.get('https://e-civic.coquitlam.ca/tempestprod/webinquiry/frames.cfm')       
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.ID,"frame_map")))
print(driver.page_source)

  • 控制台输出：
