Issue
Where can I find a list of all available Chrome Options with selenium?
While crawling with selenium in a python environment, I had to use flash in the chrome webdriver.
so I tried to find a setting that would allow Flash and I found these answers.
Selenium.Chrome where can I find a list of all available ChromeOption arguments? C#
but I really want to find official document
about these arguments :
- profile.default_content_setting_values.plugins
- profile.content_settings.plugin_whitelist.adobe-flash-player
I think that exist because some people said like above two answers.
but I can’t found it.
Solution
- open
chrome://versionin chrome address bar -
open the folder of Profile Path:, there will be a file
perference
-
copy and open the
perferencefile, it’s a JSON file, you can use JSON formater or JSON viewer online.
important, please open the copied one to avoid break your chrome if you did changes. -
I think the configuration related to flash under
profile.content_settings - open
chrome://settings/content/flashin chrome address bar, do waht you wanted settings for flash, your changes will be updated intoperferencefile, - Find out the difference between the updated and copied
perferencefile.
The difference should be you wanted chrome perference. - set perference when build ChromeOptions, like
profile.content_settings.xxx=xxx
Alternative, you can pre-config the flash settings(chrome://settings/content/flash) in current user profile and use user profile to build ChromeOptions.
Some reference:
- Manage Flash in Chrome
- Default user preferences
- Preferences vs. Policies
- Policy List
- Policy List – DefaultPluginsSetting
Policy more close to using registry/system level setting to effect all users in one machine; Preference work under user profile only effect one user, user can use it to customize upon Policy settings. But Policy has higher priority than Preference.
