Creates a new instance of the chrome driver.
Starts the service and then creates new instance of chrome driver.
Parameters
----------
options: ChromeOptions, optional, default: None - automatic useful defaults
this takes an instance of ChromeOptions, mainly to customize browser behavior.
anything other dan the default, for example extensions or startup options
are not supported in case of failure, and can probably lowers your undetectability.
user_data_dir: str , optional, default: None (creates temp profile)
if user_data_dir is a path to a valid chrome profile directory, use it,
and turn off automatic removal mechanism at exit.
driver_executable_path: str, optional, default: None(=downloads and patches new binary)
browser_executable_path: str, optional, default: None - use find_chrome_executable
Path to the browser executable.
If not specified, make sure the executable's folder is in $PATH
port: int, optional, default: 0
port you would like the service to run, if left as 0, a free port will be found.
enable_cdp_events: bool, default: False
:: currently for chrome only
this enables the handling of wire messages
when enabled, you can subscribe to CDP events by using:
driver.add_cdp_listener("Network.dataReceived", yourcallback)
# yourcallback is an callable which accepts exactly 1 dict as parameter
service_args: list of str, optional, default: None
arguments to pass to the driver service
desired_capabilities: dict, optional, default: None - auto from config
Dictionary object with non-browser specific capabilities only, such as "item" or "loggingPref".
advanced_elements: bool, optional, default: False
makes it easier to recognize elements like you know them from html/browser inspection, especially when working
in an interactive environment
default webelement repr:
<selenium.webdriver.remote.webelement.WebElement (session="85ff0f671512fa535630e71ee951b1f2", element="6357cb55-92c3-4c0f-9416-b174f9c1b8c4")>
advanced webelement repr
<WebElement(<a class="mobile-show-inline-block mc-update-infos init-ok" href="#" id="main-cat-switcher-mobile">)>
note: when retrieving large amounts of elements ( example: find_elements_by_tag("*") ) and print them, it does take a little more time.
service_log_path: str, optional, default: None
path to log information from the driver.
keep_alive: bool, optional, default: True
Whether to configure ChromeRemoteConnection to use HTTP keep-alive.
log_level: int, optional, default: adapts to python global log level
headless: bool, optional, default: False
can also be specified in the options instance.
Specify whether you want to use the browser in headless mode.
warning: this lowers undetectability and not fully supported.
version_main: int, optional, default: None (=auto)
if you, for god knows whatever reason, use
an older version of Chrome. You can specify it's full rounded version number
here. Example: 87 for all versions of 87
patcher_force_close: bool, optional, default: False
instructs the patcher to do whatever it can to access the chromedriver binary
if the file is locked, it will force shutdown all instances.
setting it is not recommended, unless you know the implications and think
you might need it.
suppress_welcome: bool, optional , default: True
a "welcome" alert might show up on *nix-like systems asking whether you want to set
chrome as your default browser, and if you want to send even more data to google.
now, in case you are nag-fetishist, or a diagnostics data feeder to google, you can set this to False.
Note: if you don't handle the nag screen in time, the browser loses it's connection and throws an Exception.
use_subprocess: bool, optional , default: False,
False (the default) makes sure Chrome will get it's own process (so no subprocess of chromedriver.exe or python
This fixes a LOT of issues, like multithreaded run, but mst importantly. shutting corectly after
program exits or using .quit()
unfortunately, there is always an edge case in which one would like to write an single script with the only contents being:
--start script--
import undetected_chromedriver as uc
d = uc.Chrome()
d.get('https://somesite/')
---end script --
and will be greeted with an error, since the program exists before chrome has a change to launch.
in that case you can set this to `True`. The browser will start via subprocess, and will keep running most of times.
! setting it to True comes with NO support when being detected. !
