如何从page_source获取iframe源

Question

您好，我尝试从page_source中提取链接，而我的代码是：

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

driver_path = r"C:\Users\666\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();

现在我只想抓取此链接

Answer 1

尝试

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

Answer 2

请尝试以下脚本来获取您要解析的链接。您无需切换到iframe即可获取链接。硬编码延迟始终是解析任何动态内容的最糟糕的选择。如果链接在5秒钟后出现，该怎么办。我在下面的脚本中使用了Explicit Wait，使其更强大。

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()

输出：
