selenium - 使用 Selenium 从动态网页中抓取内容会返回错误的内容

您正在看到正确的输出和正确的行为。

我拿走了你的代码并添加了一些选项以及一些等待，这是观察结果：

代码块：

from selenium import webdriver

options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
driver.get('https://www.dplay.no/kanaler/')
time.sleep(10)
print(driver.page_source)

控制台输出：
