When using selenium for web automation, we often encounter such a requirement. Can we continue to run automation scripts on the basis of already opened browsers?
In this way, the previous verification code login can be manually clicked, and the subsequent pages can be executed using scripts, which can solve a big pain point.
Start the browser from the command line
First right-click the desktop icon of the Chrome browser and find the installation path of chrome.exe
Copy the address C:\Program Files\Google\Chrome\Applicationand add it to the environment variable Path
Open cmd and enter the command to start the chrome browser
- –remote-debugging-port is the specified running port, you can set the easy port, as long as it is not occupied
- –user-data-dir specifies the operating data of the running browser, and creates a new clean directory without affecting the original data of the system
> chrome.exe --remote-debugging-port=9222 --user-data-dir="D:\selenium_chrome"
After execution, the chrome browser will be launched
selenium running has opened the browser
Enter my blog address on the opened browser:https://www.cnblogs.com/yoyoketang/
Create a new py file, which can be run directly on the browser without restarting the browser
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_experimental_option("debuggerAddress", "127.0.0.1:9222")
driver = webdriver.Chrome(chrome_options=chrome_options)
# 接着运行
print(driver.current_url)
print(driver.title)
operation result
