.page_sourceon a webdriverinstance is what you need:
.page_source在一个webdriver实例上是你需要的：
>>> from selenium import webdriver
>>> driver = webdriver.Firefox()
>>> driver.get('http://google.com')
>>> print(driver.page_source)

You can also get the HTML page source without using a browser. The requests module allows you to do that.
您还可以在不使用浏览器的情况下获取 HTML 页面源代码。requests 模块允许您这样做。
import requests
res = requests.get('https://google.com')
res.raise_for_status() # this line trows an exception if an error on the
# connection to the page occurs.
print(res.text)
