Error report

A small partner in the VIP full-stack answering group of thousands of people came to private message me when he encountered a problem, and wanted to use selenium to operate the browser, but an error occurred (at that time, his heart was cold for a moment, and he came to me for help, and then it went smoothly. Help him solve it, and record it by the way, hoping to help more friends who encounter this bug and will not solve it), the error code is as follows:

from selenium.webdriver.chrome.options import Options
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

def get_html_str(url):
    chrome_options = Options()
    chrome_options.add_experimental_option("debuggerAddress", "127.0.0.1:9222")  # 通过端口号接管已打开的浏览器
    driver = webdriver.Chrome(options=chrome_options)
    # driver.maximize_window()
    driver.get(url)
    html_str = driver.page_source
    return html_str

Error reason

Reason for error :

An error is reported because the driver version of the operating browser is different from the browser version.

Friends, follow the method below to solve it permanently! ! !

Solution

1. Download the corresponding driver version

1. Check the browser version:

2. Download the corresponding Chrome driver version : http://chromedriver.storage.googleapis.com/index.html

3. Select the window version:

4. After decompressing the installation package, .exeput the driver into the Python installation path :

5. Start the program again successfully:

2. Set to permanently prohibit automatic upgrade of Google Chrome

Step 1: Turn off the update service

1. Keyboard windows logo key + R key, enter services.msc, and then confirm

2. Find two Google update services, double-click to open

3. In the properties interface that pops up, click Stop first, then set the startup type to Disable, then select Apply and OK:

4. Check whether both updates are disabled:

Step 2: Turn off update permissions

Chrome updates are upgraded using the upgrade program in update, so the files inside can be deleted. But if you delete Chrome directly, it will be automatically generated again. So you can consider cutting off this step, as long as Chrome cannot generate an update program in the Update folder, then Chrome cannot be upgraded.

1. Find C:\Program Files (x86)\Google\Updatethe path and delete all the content under the file:

2. Then right-click the Update folder, open Properties, click the "Security" tab, and click Edit

3. Set the full control right of System to Deny (System is the highest authority, after setting, Chrome will not have permission to move this file):

4. Then click OK one by one to finish. At this point, Chrome can permanently disable updates.

5. Open the Google Chrome settings to check whether the setting is successful:
