How to open a Chrome Profile through Python

问题:

My script I have been writing has been working great. I just added the option so it would open a profile on chrome using this code.

options = webdriver.ChromeOptions
browser = webdriver.Chrome(executable_path=r"C:\Users\princess\AppData\Local\Programs\Python\Python36-32\chromedriver.exe", chrome_options=options)
options.add_argument(r'user-data-dir=C:\Users\princess\AppData\Local\Google\Chrome\User Data')
options.add_argument('--profile-directory=Profile 1')

When used, I get this error code.

C:\Users\Princess\Desktop>CHBO.py
Traceback (most recent call last):
  File "C:\Users\Princess\Desktop\CHBO.py", line 12, in <module>
    browser = webdriver.Chrome(executable_path=r"C:\Users\princess\AppData\Local\Programs\Python\Python36-32\chromedriver.exe", chrome_options=options)
  File "C:\Users\Princess\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 59, in __init__
    desired_capabilities = options.to_capabilities()
TypeError: to_capabilities() missing 1 required positional argument: 'self'

How do I fix this?

To create and open a new Chrome Profile you need to follow the following steps :

• Open Chrome browser, click on the Side Menu and click on Settings on which the url chrome://settings/ opens up.
• In People section, click on Manage other people on which a popup comes up.
• Click on ADD PERSON, provide the person name, select an icon, keep the item Create a desktop shortcut for this user checked and click on ADD button.
• Your new profile gets created.
• Snapshot of a new profile SeLeNiUm

• Now a desktop icon will be created as SeLeNiUm - Chrome
• From the properties of the desktop icon SeLeNiUm - Chrome get the name of the profile directory. e.g. --profile-directory="Profile 2"

• Get the absolute path of the profile-directory in your system as follows :

  C:\\Users\\Otaku_Wiz\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 2
  

• Now pass the value of profile-directory through an instance of Options with add_argument() method along with key user-data-dir as follows :

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  
  options = Options()
  options.add_argument("user-data-dir=C:\\Users\\AtechM_03\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 2")
  driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
  driver.get("https://www.google.co.in")
  

• Execute your Test

• Observe Chrome gets initialized with the Chrome Profile as SeLeNiUm

You can use options = Options() or options = webdriver.ChromeOptions() at place of options = webdriver.ChromeOptions
