如何从 page_source 获取 iframe 源

Question

您好，我尝试从 page_source 中提取 link，我的代码是：

from bs4 import BeautifulSoup
from selenium import webdriver
import time
import html5lib

driver_path = r"C:\Users6\Desktop\New folder (8)\chromedriver.exe"
driver = webdriver.Chrome(driver_path)
driver.implicitly_wait(10)

driver.get("https://www.milversite.club/milver/outsiders-1x01-video_060893d7a.html")
try:
    time.sleep(4)
    iframe = driver.find_elements_by_tag_name('iframe')
    for i in range(0, len(iframe)):
        f = driver.find_elements_by_tag_name('iframe')[i]
        driver.switch_to.frame(i)
        #  your work to extract link
        text = driver.find_element_by_tag_name('body').text
        print(text)
        driver.switch_to.default_content()

    output = driver.page_source

    print (output)

finally:
    driver.quit();

现在我只想抓取这个 link

Answer 1

试试

element = driver.find_element_by_id('iframevideo')
link = element.get_attribute('src')

Answer 2

试试下面的脚本来获取你想要解析的link。您无需切换到 iframe 即可获得 link。硬编码延迟始终是解析任何动态内容的最差选择。如果 link 在 5 秒后出现怎么办？我在下面的脚本中使用了 Explicit Wait 以使其健壮。

from selenium import webdriver
from selenium.webdriver.support import ui

driver = webdriver.Chrome()
wait = ui.WebDriverWait(driver, 10)
driver.get("https://www.milversite.club/milver/outsiders-1x01-video_060893d7a.html")

elem = wait.until(lambda driver: driver.find_element_by_id("iframevideo"))
print(elem.get_attribute("src"))

driver.quit()
