image
2、将安装的谷歌webdriver导入到项目中
image
3、简单的爬虫代码
import os
from time import sleep
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
project_path = os.path.abspath(os.path.dirname(__file__))
drivers_path = os.path.join(project_path, 'drivers')
chrome_driver_path = os.path.join(drivers_path, 'chromedriver.exe')
print(chrome_driver_path)
def learning():
driver = webdriver.Chrome(executable_path=chrome_driver_path)
sleep(2)
driver.get("http://www.python.org")
sleep(2)
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
sleep(2)
elem.clear()
sleep(2)
elem.send_keys("pycon")
sleep(2)
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
sleep(10)
driver.close()
if __name__ == "__main__":
learning()
