带def选项的Selenium Python Chrome打开

Question

opt = webdriver.ChromeOptions()
opt.add_arguments("--user-data-dir=C:\Users\Bar\AppData\Local\Google\Chrome\User Data")
driver = webdriver.Chrome(opt)
driver.get("https://www.google.com/")

但它不起作用，它说：

C:\Users\Bar\AppData\Local\Programs\Python\Python35-32\python.exe C:/Users/Bar/PycharmProjects/yad2/Webdriver.py
  File "C:/Users/Bar/PycharmProjects/yad2/Webdriver.py", line 7
    opt.add_arguments("--user-data-dir=C:\Users\Bar\AppData\Local\Google\Chrome\User Data")
                     ^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 18-19: truncated \UXXXXXXXX escape

Process finished with exit code 1

AttributeError：“Options”对象没有属性“add_arguments”

应该是add_argument而不是add_argument。你应该试试：-

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

opt = webdriver.ChromeOptions() 
opt.add_argument("user-data-dir=C:\Users\Bar\AppData\Local\Google\Chrome\User Data")

AttributeError：“Service”对象没有属性“Process”

driver = webdriver.Chrome(chrome_options=opt)
driver.get("https://www.google.com/")

driver = webdriver.Chrome(executable_path="path/to/chromedriver.exe", chrome_options=opt)
driver.get("https://www.google.com/")
